It can be said that IMTS (virtual or other) presents the ultimate manufacturing toolbox, where the latest, most innovative and proven equipment can be found in the workshop for fixing, moving, cutting, bending and inspecting workpieces. The challenges in this area are growing. The tool spindle is faster. The material is harder. The workpiece is larger, thinner, and heavier (or lighter). In the traditional material removal process, the action of the tool hitting the workpiece is violent, generating heat and force, which must be processed to ensure the quality of the final workpiece. Research in depth and you will always find a solution.

The BIG Kaiser Precision Mold Company of Hoffman Estates, Illinois, released a new type of closed-loop boring system with an intelligent, fully automatic fine boring head. When used with an in-process measurement system, the system can automatically compensate for cutting edge wear, thereby reducing scrap, improving accuracy and saving time.

The diameter movement range of the EWA68 boring head is 0.866 inches (22 mm), and the smallest blade holder is used, with a diameter range of 2.677-3.543 inches (68-90 mm). This means that a boring head can be used to produce similarly sized holes on the same part. By adding two larger blade holders, the diameter range can be expanded to 5.197 inches (132 mm). Integration options for existing machine tools include an external industrial PC for handling machine control communications and EWA boring head adjustments. Machine controls that may need to be updated are suitable for processing EWA software.

For the lower level of integration (there is no measuring tool in the process), BIG Kaiser Precision Tooling provides a third way of implementation, in which the boring head adjustment is done by inputting manual data into the tablet or mobile device used to control the boring head To move.

Bluco of Naperville, Illinois pioneered the development of modular fixtures for welding, machining, inspection, and assembly, whose components and fixtures can be reassembled and reused. Typical applications include position welding tables, basic workstations, power manipulators and robotic welding fixtures. In order to make welders safer and weldments more precise, Bluco fixtures and ALM positioners can be combined to create a solution designed to fix and position multiple parts through a modular kit. The positioner allows the part to rotate 360°, which eliminates heavy work and makes welding more comfortable. Bluco modular tools and ALM positioners are compatible with more than 400 modular components and provide welding solutions for variable size or large heavy parts.

Bluco's newly developed product, the ultra-large modular fixture system (see opening photo), is designed for the largest parts manufactured on vertical and horizontal CNC machines. The tolerance between the holes of the fixture system is ±0.0006 inches (0.015 mm). Customized solutions are suitable for machine tools or pallets with 20' (6 m) or larger substrates.

Lang Technovation of Hartland, Wisconsin, produces workpiece clamping and automation technology for milling applications that complements its zero-point clamping and automation system. Its closed mold technology provides a guarantee for the processing from raw materials to finished workpieces. In addition, the cleaning fan product line will automatically clean the machine tool table, pallet and/or workpiece after the machining process.

Lang's new Makro•4Grip clamping system extends its patented Form-Closure technology to round parts with a diameter of up to 300 mm. The Makro•4Grip system consists of universal punching pliers with repositionable inserts (for different diameters) and matching clamping pliers. These clamping pliers are suitable for Lang self-centering vises of various sizes. The jaws can be used as a compatible jaw kit for all 77 mm and 125 mm wide vises.

The jaw clamps the pre-punched workpiece with a clamping height of 3 mm through four notches. Makro•4Grip mold clamping and clamping system adopts the tried and tested principle of clamping and clamping, and it has been used for square and rectangular workpieces. Makro•4Grip provides a clamping range that can support workpieces with a diameter of 36-300 mm, so that it can seamlessly transition to a large diameter Preci-Point chuck.

SMW Autoblok in Wheeling, Illinois introduced the SJL six-jaw (2 + 2 + 2) equalization and self-centering power chuck. According to the company, SJL is specifically designed for CNC machining applications to provide the highest accuracy for thin-walled and deformation-sensitive workpieces. According to application requirements, SJL can switch from a 2 + 2 + 2 lever balanced chuck to a classic six-jaw self-centering chuck.

By using the 2 + 2 + 2 lever balance function, you can ensure that the gripping force of each jaw group is equal in pairs and continuously contact the workpiece, thereby providing higher concentricity and axial runout accuracy. This minimizes the deformation or inaccuracy of the raw material. The six-jaw self-centering option can provide concentric fixture locking plates for all consecutive six-jaws, so that the chuck can hold round, machined diameter and thin-walled workpieces that require the same wall thickness.

SJL's centrifugal force compensation function can provide constant gripping force at higher speeds and feeds, thereby shortening production time. SJL adopts Proofline seal to prevent contamination inside, while providing consistent lubrication, which can extend maintenance intervals. It can accommodate a tongue-shaped or serrated upper jaw, with sizes ranging from 225 to 400 mm.
