SMW Autoblok says its connectable ZeroAct workpiece positioning system is ideal for manual and electric zero-point clamping in a variety of machining applications including milling, inspection and finishing operations.

With an ultralow profile of 40 mm and a flat design, the company says ZeroAct works especially well for zero-point applications where z-axis travel of the spindle is critical. The ZeroAct features rapid open and closing of the modules and simultaneous actuation with one twist of the wrist generating 15 kN clamp force. A low stack-up of 38.1 mm increases z-axis travel and better allows for actuation of workpieces onto tables and adapters.

The modular ZeroAct system, with its compact size of 150 x 150 mm, offers the ability to attach up to three clamping modules in a row with a connecting pin that is available in sizes from 5 mm to 105 mm. By actuating the first unit, all three units clamp simultaneously, adding flexibility to machine operations, saving time and increasing operator safety.

ZeroAct is also available in an electric e-motion version to fully automate the manufacturing processes. This version uses a 24V power supply that operates with a built-in electro-motor. Pull down pins are fully interchangeable with the manually operated ZeroAct and other APS/WPS zero-point systems.

All modules feature corrosion protection and have a built-in air cleaning function to ensure the clamping system's support surface remains clean and free of chips during changeover or automation. This reduces maintenance and production time, while providing a repeat accuracy of <0.005 mm.

ZeroPoint is part of SMW’s lineup of stationary workholding systems that include manual and pneumatic WPS/APS clamping modules, fully customized and self-centering vises that integrate with automation and pallet systems, and SinterGrip clamping inserts for ultra-low clamping depth and no pre-marking of parts.
