Workpiece Positioning System Features Simultaneous Actuation

SMW Autoblok’s connectable ZeroAct workpiece positioning system is well suited for manual and electric zero-point clamping in a variety of applications, including milling, inspection and finishing operations.

With a low profile of 40 mm and extremely flat design, ZeroAct is well suited for any zero-point application, especially those where the Z-axis travel of the spindle is critical. The ZeroAct features rapid open and closing of the modules, and simultaneous actuation with one simple twist of the wrist generating 15 kN clamp force. Users can easily actuate workpieces onto a table or adapter with a low stack-up of 38.1 mm, thereby greatly increasing the Z-axis travel.

The modular ZeroAct system, with a compact size of 150 × 150 mm, offers the ability to easily attach up to three clamping modules in a row with a connecting pin that is available in sizes from 5 to 105 mm. By actuating the first unit, all three units clamp simultaneously, therefore it is not necessary to lock each unit individually into position. This gives users tremendous flexibility in machining operations, while also saving time and increasing operator safety.

The ZeroAct is also available in an electric e-motion version to fully automate manufacturing processes. Using a 24 V power supply that operates with a built-in electro-motor, this system offers great flexibility for machining processes, the company says. Users can switch between a manual and electric ZeroAct version for fully automating load and unload processes. Pull down pins are fully interchangeable with the manually operated ZeroAct and other APS/WPS zero-point systems.

All modules are sealed to protect against corrosion and feature a built-in air cleaning function to ensure that the clamping system’s support surface remains clean and free of chips during changeover or automation, thereby greatly reducing maintenance and production time, and providing a repeat accuracy of <0.005 mm.
