High Precision ER Collet

ER collets provide excellent run-out characteristics for applications requiring high-precision gripping of tubular material. The collet is retained with a threaded retaining cap that enables quick changeover, and is configured in a “fail-safe” normally-closed mode where full clamping force is applied when no air pressure is present.

Integral Rotary Union

Air is delivered to the collet or gripper assembly through an integral rotary union using a seal-less, frictionless design. This 100% noncontact rotary-union design ensures a lifetime of maintenance-free operation. The combination collet chuck and rotary union assembly also has significantly less friction and inertia than external assemblies created from discrete parts. This reduced inertia improves system performance by allowing higher peak acceleration and reducing position error during laser machining operations.

Brushless Direct-Drive

To maximize positioning performance the ACS series utilizes direct-drive brushless motor technology. Direct-drive technology is optimized for 24/7 production environments, as there are no brushes to replace and no gear trains or belts to maintain. Direct-drive also provides quicker acceleration and higher top speeds than gear- or belt-driven mechanisms, which yields higher total overall throughput.

The low maintenance, high throughput characteristics of the ACS coupled with the integral material handling capability provide the lowest total cost of ownership when compared to component-level solutions.
