Zero-point clamping system
BIG KAISER Precision Tooling Inc.
The quick change Unilock zero-point clamping chuck system can reduce machine set up time by up to 90% while increasing accuracy and repeatability to greatly improve your overall efficiency. Unilock utilizes spring pressure to drive wedges against a tapered wedge lock (clamping knob). Air pressure is used to compress the springs, releasing the wedge lock. Many different models available depending on your applications.
Clamping is achieved by bleeding the air pressure out of the chuck. To facilitate palletization, the clamping knob is attached to a base plate, fixture or directly to a workpiece. The result is quick and repeatable clamping of .0002" or better.
