Workholding Systems With A Competitive Edge

IMTS 2024 offered visitors an opportunity to browse through a number of new and improved workholding systems that reportedly will help shops streamline automation, improve precision and/or reduce downtime and setup times. What’s more, the following eight products highlighted here reflect key trends in automation, flexibility and maintenance-free operation — each of which are critical for staying competitive in today’s manufacturing sector.

1. HAINBUCH America Corp. introduced new process automation for workpiece clamping with the unveiling of its Automated Change (AC) Line at IMTS 2024. With the company’s TOPlus AC and SPANNTOP AC chucks, clamping heads and workpiece end-stops can be changed automatically. The chucks enable unattended setup and manufacturing of workpieces with different clamping diameters, profiles and clamping lengths. The DockLock AC zero-point clamping system enables automated fixture change-over for both hydraulic and pneumatic versions. Hainbuch’s CENTREX duo AC and centroteX AC interfaces enable change-overs for entire clamping devices, and can be adapted to a shop’s unique requirements.

2. Mate Precision Technologies introduced a series of new enhancements for its 52/96 zero-point workholding system. Featured at Mate’s booth during IMTS 2024, the enhancements include the company’s new machinable hard jaws that allow users to create custom profiles from blank jaws. Also highlighted were Mate’s DynoGrip ER Collet Chucks for holding round parts during milling; the DynoGrip Direct Mount Vise with a wider body that provides additional flexibility and allows for direct bolting to a machine bed, pallet or other fixture, and the DynoMount Lower Profile Pyramid designed for more compact machining spaces.

3. SMW Autoblok Corp. introduced its WPS XL (Workpiece Positioning System) featuring manual zero-point clamping that is best utilized for large workpieces. The WPS XL is said to be ideal for 5-axis machining, and is used for milling, measuring and grinding operations. With an emphasis on flexibility and speed, users reportedly can reduce their setup time by 90% or more with single quick actuation for rapid module operations in only three rotations. The new system features a pull-down force of 40 kN, holding force of 100 kN, maximum torque of 30 Nm, and repeatability of less than 0.01 mm.

4. Royal Products highlighted its Royal Z-Lock zero-point workholding system designed for vertical, horizontal and 5-axis machining centers . The system, which does not require the installation of external air or hydraulic lines, takes just a few turns of a hex key to lock, and there is no risk of the top plate loosening from vibration, spring wear or air/hydraulic failure. The Royal Z-Lock system is said to achieve up to 11,240 lbs. (50 kN) of clamping force, and is capable of precision repeatability of 0.0001″ in the X and Y axes, and 0.00005″ in the Z axis.
