Automated electrical discharge machining solves the technology gap and optimizes production for aerospace manufacturers.
For aerospace manufacturers, electrical discharge machining (EDM) has long been the answer to achieving high precision and precision. The industry has applied this technology to various parts, especially parts exposed to high temperatures and pressures. Due to surface damage, some manufacturers abandoned early EDM equipment, but continued development has led to a more stable and predictable process. These improvements include automation components. Robots, processing systems and sensors can provide real-time feedback, higher repeatability and higher quality.
In the following Q&A, Mike Bystrek, National EDM Product Manager of MC Machinery Systems, discussed other advantages of EDM automation, available tools, and implementation considerations.
It boils down to knowing how many parts you really need to produce, and helps to avoid any guesswork, so that the cost of work is controlled. For example, Erowa Robot Compact 80 can be implemented on sinker EDM to perform automatic electrode replacement, and it can also replace parts. Therefore, a good long-term solution is to increase productivity and reduce overall costs.
The biggest advantage of automation is to increase productivity while reducing delivery time. After the process is validated and automated, it can provide repeatable results every time. In the end, you can reduce your labor costs, improve the quality of parts, and provide profitability.
On the wire rope and sinker, we all have an artificial intelligence (AI) system that allows the operator to input/answer some simple questions on the control system so that the machine can take over. The system uses real-time status monitoring during the combustion process, and directly modifies specific parameters to achieve a stable cutting effect, so as to obtain the best results. Since AI technology analyzes this data, it can reduce the overall wear of the electrode and reduce the cost.
In today’s workforce, the older generation of toolmakers in the workshop are retiring and attracting young people, which is great. But sometimes, this experience does not transfer. Therefore, our experience or knowledge accumulated directly in the machine can enable operators at all levels to obtain high-quality results.
Before the process can be fully automated, it must be demonstrated that the process is complete. You need to make sure you can get the part, place the part repeatedly on some tool on the machine, cut the part, and make sure you get the same result. Once the whole process has been proven, I think you can proceed with automated operations like 24/7. Sometimes people skip the basic steps and try to implement them directly, but then they miss the obvious.
In this industry, whether it is aerospace, tool and mold industries, or any type of manufacturing, they are looking for skilled professionals to complete a lot of work. Having skilled technicians to set up such a thing and allow customers to automate it will enable them to work with lower overhead, thereby making them more profitable. Analyzing to determine whether the results will reduce total turnaround time or increase productivity or product certification, this may be the first thing I consider automation.
It also boils down to dollars and cents. Do you really want to pay someone X dollars to stay there, pull a part of it, and then take it out? Everyone is worried about them going to work, but I think this will make a company profitable and may provide more opportunities for people to train them in other areas. That's the way they should look. By allowing this, productivity can be increased, and your store will be more profitable.
The important thing is that we must better accept EDM and smart tools and controls that can be combined. This is the best way to produce cheap parts faster.
MC Machinery Systems’ EDM automation solution enables manufacturers to greatly increase production and maximize resource utilization. The EDM automation unit can use Roku-Roku high-speed vertical milling machines and robots to speed up the production and replacement of electrodes, and achieve a complete light-off operation. MD + CELL allows the wire cutting machine to continuously load and cut workpieces immediately, and automatically load and unload workpieces. Users can also use Mitsubishi robots, 3R, Erowa or Hirschmann for automation. Application experts can also devote themselves to developing customized EDM automation solutions that are particularly suitable for stores.

Hurco cooperated with ProCobots to develop a simplified automation package for high-mix manufacturing, making workshop automation feasible. It provides a flexible, easy-to-program and easy-to-transfer automation package to other Hurco machines without the need for an integrator To make. change.
The Automation Manager control function seamlessly integrates automation into CNC machines. It includes a setup wizard, job and queue progress bar, a graphical interface between a collaborative robot (cobot) and a CNC machine tool to simplify the easy setup process for each job, run multiple jobs in sequence, and load and save job sets.
The intelligent manufacturing platform seamlessly connects industrial assets and business systems to collect data, and provides real-time data collection and monitoring from any industrial asset, regardless of brand, age or process. The report can be accessed anytime and anywhere through a browser device. This cloud-based Internet of Things (IoT) platform includes customizable dashboards and alerts to identify manufacturing bottlenecks and inefficiencies and simplify manufacturing processes.
Freedom Platform can be used on three plan levels to adjust the size of the program according to the needs of the personal store and process.
The DST20 miniature strain sensor can measure static and dynamic forces in the range of 500µm/m to 1,000µm/m even in a limited space. The size of the fixed sensor is 28mm x 12mm x 10mm. Thanks to the stainless steel housing and IP65 protection level, it can withstand the severe tests in industrial applications. They are suitable for challenging industrial environments and mechanical engineering applications as well as routine process automation. The output signal is 1.0mV/V, which is connected through the M5 4-pin male connector.
The OnRobot screwdriver is an intelligent, out-of-the-box device that allows manufacturers to quickly, easily and flexibly automate a series of assembly processes.
Programming only needs to input the appropriate screw length and torque value in the user interface integrated into the robot teach pendant. With precise torque control and embedded shafts, the screwdriver can automatically calculate the necessary speed and force. It can detect incorrect screw lengths, thereby improving overall quality and reducing scrap. Using the Z axis, the screw retracts into the tool and automatically drives after the robotic arm moves into place, which reduces the movement of the robotic arm and additional programming. When moving, the 35mm screw will be completely retracted into the screwdriver until the screwing process is safely started, thereby enhancing the ability to cooperate.
Advances in wire additive manufacturing (AM) technology have created new opportunities for prototyping, production of old parts, and aerospace tools.
Manufacturers are under constant pressure to deliver prototypes, produce and replace parts at an ever-increasing rate, while maintaining quality. Wire-based metal additive manufacturing (AM) technology can help manufacturers meet this challenge in the following situations:
Lincoln Electric, headquartered in Cleveland, Ohio, is known for its arc welding and cutting products and automation systems. With its own technology, materials, automation and software to produce large, complex metal parts, it has always been at the forefront of additive manufacturing. .
Lincoln Electric Additive Solutions Business Development and Sales Manager Michael (Mike) S. Wangelin has a background in defense aeronautics and he also recently spoke about innovation on behalf of Lincoln Electric subsidiary Baker Industries (Michigan, Michigan)
Wire-based AM basically uses advanced gas metal arc welding (GMAW) power supplies, industrial robots, and software that combines the robot's motion with a multi-axis positioner to place continuous welds to create free-form 3D shapes. It differs from metal powder-based AM in that the technology enables larger builds and is not limited to build rooms. The only restriction is the movement of the robot or the unit used for construction. We are currently dealing with a build volume of 4ft x 6ft x 6ft and can be expanded as needed. No special environment is needed, just close it to collect the flue gas with local protective gas.
Prototypes in polymers or plastics can bring concepts to physical objects in a short amount of time, but it cannot represent the actual part of strength or weight, so it is limited to demonstration purposes, not functional testing. In our process, the intensity will be closely matched or the same as the production. By initially prototyping with metal, you can understand the product being produced, while for polymers, you can only use conceptual objects. Metal is a better match and closer to the final product.
The period of discontinuation of parts that are usually defined in paper 2D drawings is difficult to reproduce in the current manufacturing environment. You can scan the part, capture it digitally as a finished object, and then quickly recreate it using 3D printing. Compared to machined or cast surfaces, Wire AM has a greater surface variation-it is close to the final shape, so it may be necessary to remove excess material from critical areas, but it does not necessarily have to be completely removed to save time.
There are many polymer and metal 3D printing service providers, many of which use off-the-shelf equipment and materials, so they are limited to using commercially available items to create objects. The difference between Lincoln Electric is that we control the entire process from start to finish, so we manufacture power supplies, welding equipment and our own welding wire materials. Lincoln Electric has decades of experience in the field of advanced automation, and owns and develops software that uses 3D models, creates build routines, and controls robots and positioners. From the start-up design to the completion of the product, every piece of work is under the control of Lincoln Electric. With the strength of the large Lincoln company, we are able to invest in each advanced technology field in this process, thereby promoting the entire process.
A key step in establishing a 3D printing solution team within Lincoln Electric is to have the software that slices the 3D model into thin slices to prepare it for 3D printing, generates the deposition tool path, and controls the system. Therefore, the company adopted the software originally developed for complex 5-axis NC machining and adapted it to AM, which is a product called SculptPrintTM. Owning the software owned by Lincoln Electric provides us with an advantage that as we understand the process and continuously improve its efficiency, we can continuously make changes to the software, so there is no delay between discovering problems and making changes, and using third parties In the case of software, you can fall behind in making these advancements.
We are currently printing steel, high-strength low-alloy steel, stainless steel, Inconel, and bronze. Recently, we are using it with Invar. Nickel-based alloys have become the first choice for aerospace composite curing tools due to their thermal coefficient. The material expansion matches the parts being produced. In addition, Invar alloy also has durability and wear resistance.
It is basically a 5-foot-long cube, but it is partially dependent. If it is narrower, we can print up to 9 feet-only limited by the reach of the robot. If we need to exceed our current construction volume, we can use a larger robot or base to lift the robot. The length of several projects we are working on is 14 feet. We are printing 4ft to 5ft line segments vertically, connecting these line segments together, and then welding them together after printing. Printing shorter segments can also reduce cycle time.
MW: As parts become more and more complex, AM's delivery time and cost begin to drop. Tooling is the last item needed before production starts, so there is always the pressure of planning to produce tooling as soon as possible, and we think this is our advantage because we can shorten the cycle and shorten the delivery time, especially for complex tools.
Any object with high curvature, such as an intake pipe, has a complex contour shape, multiple angles or curved outer skins. Traditionally, you can use plates with collision and forging skills to make tools, or you can use blanks to machine them. Using our wire additives, we can rotate parts, and the motion of the robot allows you to build complex parts without supporting structures. It is carefully designed to control the movement of the robot and the angle of the cutting torch, while rotating and rotating the positioner of the fixed part. Multiple devices are rotating, and all devices are programmed using SculptPrintTM software.
Lincoln Electric is selling metal AM 3D printing services as a printing bureau, using 75,000 feet of dedicated
The plant in Cleveland currently has 18 production units. We are cooperating with Baker Industries, which uses its 35 3-axis and 5-axis CNC centers for machining, prototyping or tooling, or to provide customers with printed materials for close-range online processing.
The customer provided the solid model and printed the finished parts or production tools, and provided us with the parameters. We can design according to our needs, we can also use a complete design or a variation between the two. Or bring us the existing design of the product you want to produce. We will print and can also redesign for AM to provide alternatives to reduce time or cost. Or provide us with an existing part where tools or engineering drawings no longer exist.
Aerospace manufacturing and design.
The Quality Information Framework (QIF) standard helps simplify data collection, storage, and sharing.
Engineers and managers use measurement data collected by aviation mechanics and inspectors in workshops and quality laboratories around the world to meet customer requirements, comply with Federal Aviation Administration (FAA) requirements or other government requirements, and monitor product quality and manufacturing performance .
However, manual collection and retention of dimensional data is inefficient, can lead to costly errors, and incur costs related to the storage and maintenance of paper records for the product life required by the aviation industry. As a result, aerospace manufacturers are steadily reducing paper records in favor of high-quality data management software that can capture and store information digitally.
The aerospace industry relies heavily on its extended supply chain to produce high-quality products, but the number of parts and suppliers involved in manufacturing aircraft is huge, making it difficult to track products. Aerospace manufacturers are highly supportive of improving the supply chain so they can improve part quality, profit margins and overall safety of air travel.
This can be achieved by using digital threads, which can be tracked during the life cycle of each part. Quality data management software plays an important role in a company's ability to support digital threads. The software contains basic information, such as part tolerances and measured values. The process capability statistics calculated based on these measurement values can generate performance charts of the manufacturing process. When the required information or other software that can use the data cannot obtain the necessary information, the expanded enterprise will not be able to achieve its due efficiency.
Manufacturers implementing digital threads must choose interoperable software that uses communication standards such as Quality Information Framework (QIF).
QIF has been published and accepted as an ANSI standard in 2013 and has been submitted to ISO/TC 184/SC 4 Industrial Data (ISO/DIS 23952) by the Digital Metrology Standards Association (DMSC). Once accepted, the standard should be adopted more widely.
Adopting the QIF standard should give aerospace manufacturers a clearer view of all parts and products received. QIF stores product information in documents written in Extensible Markup Language (XML). Since XML is commonly used, QIF documents can be easily transferred to aerospace manufacturers across the supplier level through its enterprise resource planning (ERP) software, all of which may be different.
However, when software application developers create proprietary communication protocols, or if private organizations create their own standards, the entire industry takes a step back. Information is no longer easily shared. Because organizations cannot reach a consensus on which agreement to adopt, companies will eventually turn to spreadsheets and PDFs to share information. If a proprietary format is agreed, it becomes expensive to adopt a proprietary format because it is developed by a private organization with its own interests.
However, QIF is free. The XML format is easy to adopt, allowing companies to choose applications that best suit their needs, rather than applications that are only suitable for specific machines or software.
For serialized aerospace parts, conventional feature naming systems including balloon IDs are being supplemented with Universally Unique Identifiers (UUID), which is a standard format ISO/IEC 9834-8:2005. Conventional feature naming systems have been supplemented because they cannot provide unique identifiers throughout the enterprise.
The QIF result files are serialized and are ideal for long-term archiving and retrieval (LOTAR) (http://lotar.prostep-ivip.org), thus eliminating the problems associated with managing, tracking and finding measurement data for specific parts or features.
For example, a database search for "Diameter_28" will return thousands of results for this feature from many parts and assemblies. However, a feature search in one or more QIF documents will find a specific UUID, which will return immediate and accurate results for IDs that will not be repeated.
In the machine unit, the QIF file containing measurement results and statistical data can feed the information back to the machining center for the controller to perform tool compensation, thereby ensuring high-quality manufacturing.
Machine tool controllers are becoming more and more intelligent every day. Many controllers can manage tool wear, estimate cycle time and report machine tool status. However, all these functions require information. In order to adaptively compensate for tool wear, the information required by the machine tool controller must be operable. In this case, it is measurement results and statistical information. For example, the measurement data from the coordinate measuring machine (CMM) that measures the newly processed parts can be calculated as useful process capability statistics through the quality data management software. Then, the machine tool controller can read the information from the QIF results and statistical files to automatically make the necessary corrections to the next part. Closed-loop manufacturing can reduce costs, reduce part tolerances and improve processing capabilities. This also frees up more time for operators to perform other tasks and only requires them to participate in tool compensation in emergency situations.
The future of manufacturing lies in smart factories-more data, more sensors to collect data, and a more interconnected manufacturing space.
A smart factory requires aerospace machine and software suppliers to be able to communicate with each other and share parts and measurement data through the use of QIF and the use of digital threads. Part quality can be confirmed, and manufacturers can respond more quickly to real-time issues that affect delivery.
The interconnectivity of manufacturing plants between different software applications and machines, as well as the sharing of information with partners and suppliers through the entire supply chain, will be indispensable for profitable aerospace manufacturing.
Accurate shop floor measurement can shorten turnaround time while maintaining quality.
Fast quantification of part defects can directly lead to faster turnaround time (TAT) by reducing inspection time. Accurate metrology eliminates any doubts about the severity of defects, reduces scrap and increases production, thereby further improving TAT.
Inspection techniques widely used in maintenance, repair, and overhaul (MRO) workshops can provide fast TAT, but usually cannot accurately assess defects. Alternatively, the technology that provides the required accuracy may come at the cost of fast TAT. In order to provide fast and accurate defect detection, 4D Technology has developed the 4D InSpec surface gauge, which puts metrology and 3D measurement in the workshop.
Visual tests and nail inspections can quickly find defects. Inspectors use fingernails to make educated guesses to understand the size of scratches, scratches, or bruises. Although some inspectors are good at classifying larger defects into a certain depth, it does not provide quantifiable data and is subjective. When unsure whether a defect is acceptable, inspectors tend to make mistakes and reject them. This gray area usually results in the rejection of parts that meet specifications. Studies have shown that visual inspection can only correctly identify about 85% of defective parts, and incorrectly reject 35% of high-quality parts. 1 The result is that MRO facilities lose millions of dollars in quality parts every month. Visual and tactile inspections may provide very important fast TAT, but at the cost of yield. Scribers are more energizing parts than nails, but they usually cannot penetrate the bottom of parts, and finding suitable reference areas on complex geometries adds further uncertainty.
Another defect measurement technique is to combine replication with an optical comparator or stylus profiler. This method uses expensive replication materials, may take about 30 minutes to complete, and only provides 2D traces on a single defect. The defect is not drawn across the entire range – the deepest part of the pit may not yet intersect the measured cross section, leaving the deepest point unknown. In addition, which pit is the deepest is not always visible visually, because discoloration and shading can cause uncertainty. With any of these restrictions, the inspector rejects the part instead of passing a potentially bad component.
Nano-resolution inspection can remove the gray area, but usually requires measurement to leave the workshop in order to use a laboratory-based 3D optical profiler or a contact-based stylus profiler for inspection. The transportation process and the demand for the instrument will push the TAT to several weeks. These instruments are much more expensive than other processes (up to $200,000) and require trained and designated operators. Moreover, the system only measures smaller parts and samples, which means that larger parts need to be checked for duplicate defects. These systems provide the high resolution necessary to accurately measure defects and increase yield at the cost of TAT. Often, operators will reject or rework unquantified defects in parts instead of slowing down the process of adapting to high-resolution technology.
4D Technology worked with the three major engine manufacturers and various MRO organizations to install high-resolution instruments in the workshop. 4D InSpec and 4D InSpec XL are anti-vibration 3D surface measuring instruments designed for portable, fast and accurate measurements at existing inspection stations. Polarized structured light technology allows handheld gauges while maintaining a high resolution of 0.0001 inches (2.5 µm). 2Inspectors can perform accurate in-situ defect quantification without sending parts to the laboratory.
Through non-contact and non-destructive measurement of surfaces from rubber to polished metal, defect analysis using 4D InSpec is like taking a picture. The instrument communicates with a desktop, laptop or tablet computer via an Ethernet cable. Data collection and analysis takes place within a fraction of a second and is displayed to the inspector through the analysis software. Aviation customers can use backpack power supplies and handheld tablets to maximize the portability of applications, such as on-board measurements.
By providing real-time data and reducing labor, the measurement system can be applied to parts to reduce TAT. The folding mirror attachment allows 4D InSpec to perform measurements outside the line of sight. For an aerospace manufacturer, because there is no need to disassemble all parts, being able to enter a narrow space can save a week of labor (per measurement).
2D technologies (such as styli and optical comparators for defect measurement) are common in the workshop, but the disadvantage is the lack of area-based measurement. There is no guarantee that the two-dimensional trajectory can measure the most extreme part of the defect, and each defect must be measured sequentially. For parts with many defects, this can be time-consuming.
3D measurement can map every defect in the field of view, ensuring that the deepest part of a long scratch is measured. At the same time, measuring each defect in the field of view can quantify dozens of corrosion points, so the deepest point will be automatically displayed.
InSpec's design allows macro areas to cover and access recessed features while maintaining high vertical and horizontal resolution. The feature analysis function of the software can display all the data of each feature in the measurement, so the inspector does not have to evaluate each defect individually. This is especially useful for checking corrosion pitting or spot shot peening. Accurate measurement of defects means that inspectors can stop filling depth due to uncertainty, thereby reducing unnecessary rework and scrapping of otherwise good parts. In addition, the results can be printed, exported to a file or uploaded to the facility’s quality control system, thereby providing a comprehensive digital record of the measurement. If you have any questions about the results, you can view the records and even re-analyze them later.
3D measurement is also a powerful tool for evaluating key small geometric shapes such as edge breaks, radii and chamfers. If the 2D trajectory is not perpendicular to such a feature, the calculated radius of curvature or chamfer length will be artificially larger due to incorrect trajectory direction. Edge breakage and characteristic radius are important annotations for many aerospace components. It is unrealistic to rely on the operator to correctly obtain an accurate 2D trajectory. The 3D data enables the software to mathematically find the true radius of curvature or chamfer angle and size without manual judgment. Since this function is sampling on hundreds of lines, the result is more comprehensive and the accuracy of the operator is ensured.
The 3D measurement of the rivet enables the software to analyze the flatness of the rivet and its depth or height relative to the surrounding surface. Users can set pass/fail thresholds in the software according to their own specifications, and receive instant feedback for each measurement.
0.3" x 0.3" (8mm x 8mm) field of view, 1.4" (35mm) support distance
0.6" x 0.6" (15mm x 15mm) field of view, 2.3" (60mm) pitch.
As the MRO industry strives to improve TAT while maintaining quality, the need for accurate shop floor measurements becomes more and more important. Accurate and simple 3D metrology enables inspectors to appraise parts up to the specification line. This reduces unnecessary scrap and rework without the risk of passing defective components. The handheld workshop measuring tool can automatically determine the deepest feature in the measurement area, and if there are multiple pits or scratches, it can be automatically determined. This measurement provides edge break, chamfer and radius analysis, so that a system can complete multiple inspection tasks. Finally, if historical records and exact results need to be reviewed, digital recording of measurement results is essential.

Rego-Fix tool holder solutions can extend tool life and reduce K&G Manufacturing costs.
For K&G manufacturing, a motto is always the center of the entire store: our next order depends on the quality of our last shipment.
Thanks to high-speed machine tool spindles, cutting tools and tool holders, the shop prides itself on being able to meet the needs of the most demanding customers in the industry.
The company mainly focuses on aerospace, marine and defense, as well as other customers from the medical, heavy equipment, high-tech and entertainment industries. Maintain customer loyalty by minimizing defects and maintaining a high on-time delivery rate.
Tool Crib manager Joe Pleskonko oversees K&G’s $500,000 tool inventory to support its 41,000 feet
Various tasks performed on high-performance machine tools in manufacturing plants. The company also designs and produces tools and fixtures in-house.
Like all K&G team members, Pleskonko takes the company's motto seriously and strives to find ways to speed up operations and optimize production.
Pleskonko said: "We run high-performance milling chucks, we want to complete the work as soon as possible, so we will vigorously promote tools."
However, the various hydraulic supports used cannot keep up with the 20,000rpm and faster spindles of the company's machine tools. To find a solution, Pleskonko cooperated with K&G manufacturing supplier Productivity Inc..
“We work with our customers to identify solutions and validate them on their parts and machines,” said Patrick Miller, Productivity’s external sales specialist. "Seeing the implementation of the solution can give them the confidence they need to make decisions. At K&G, they are engaged in many high-end, high-speed jobs, so accuracy is crucial."
Miller and Pleskonko considered many solutions, but decided to check the performance of Rego-Fix Tool Corp.'s powRgrip system. powRgrip does not rely on heating or hydraulic solutions, but on mechanical interference between the tool holder and collet to generate up to 9 tons of clamping force to clamp the tool, and ensure that the runout is less than 0.0001" over 20,000 cycles.
To test the powRgrip system, K&G chose to run it 5 days a week for 50 weeks. With the previous tool holder, K&G has achieved a tool life of approximately 15,000 to 20,000 cutting inches, requiring a tool change every three days a year, and 83 tools a year. Using powRgrip, the tool life has been increased by more than three times, achieving a tool life of 60,000 to 70,000 cutting inches, and 21 tools can be used per year.
Pleskonko said: "This means saving 62 tools per year, each tool is 60 US dollars, and the annual saving is 3,720 US dollars." "That's just a tool. In addition, the operator does not have to change tools frequently, which can prevent the impact of accuracy and/ Or increase the conversion of the set time."
With the help of K&G's PGU 9500 automatic clamping device, the heat-free process can be realized faster, and the clamping device can be safely and reliably clamped and loosened at the push of a button.
However, the advantages of the powRgrip system extend beyond the tool life or set-up time. Using the previous tool holder in this workshop, the tool will begin to produce heavy burrs after cutting 15,000". On the other hand, powRgrip can provide excellent clamping force, rigidity and balance, prevent burr formation and produce a consistent surface finish. Reduce deburring time and save time for employees working on other benchmarks.
Ryan Morris, a manufacturing engineer at K&G, is very grateful for the anti-bounce function of the powRgrip system and looks forward to finding new applications for tool holders.
Morris said: "I want to use it on many roughing tools, and I know I will get significant benefits." "In seven months, we didn't have any tools to pull us like traditional systems."
Pleskonko is so satisfied with the results of the powRgrip system that he is considering other solutions from Rego-Fix. "In order to grind parts (large and large castings), we will push our tools faster and faster to remove material. The faster we cut, the better. Therefore, we will definitely consider other solutions such as secuRgrip Program."
A typical workpiece weighs 5 to 75 pounds and includes everything from relatively small components to 28-inch long engine blocks. The size of the work batch may vary from 50 to 500 per month. The workshop mainly uses cast aluminum and billet aluminum processing, although it also processes some steel and cast iron.
K&G's aerospace work usually involves the fuel tanks and fuel pumps of large airplanes, so high-precision parts need to be produced in large quantities, while its medical work is usually small parts with functional surfaces. Its business department in the marine industry is responsible for almost all mechanical processing and assembly of the entire inboard and outboard engines.
In order to keep up with these extensive work, Pleskonko, Miller and other members of the team constantly re-evaluate the equipment. So far, the Rego-Fix powRgrip tool holder system has passed all tests.
Pleskonko said: "We will always keep a list of the advantages and disadvantages of the equipment and tools used, but for powRgrip, I still haven't added anything in the con column. It just keeps overwhelming everything else."
