Improve productivity and lower costs by enhancing workpiece quality . . . . . .
through accurate and repeatable workholding. Manufacturers maintaining high concentricity throughout a workpiece's machining process benefit from lower scrap rates, reduced cycle times and increased production capacity. By holding close tolerances and minimizing the amount of material left for finishing, you not only reduce your cost per part, but you also end up with more parts produced at the end of each shift. The high repeating accuracy of MicroCentric PPC Series Power Chucks also provides the capability to improve workpiece parallelism, roundness, and squareness, as well as holding closer size tolerances.

 

 


Accuracy within .00005" TIR

A standard repeating accuracy of .00005" TIR means the radial and lateral runout of your workpieces will be held within .00005" (0.0012mm). Models with higher accuracy are also available.

 
 



 

PPC Chuck Design
Aircraft quality materials including a hardened alloy steel chuck body, actuators, and base jaws are used to manufacture PPC chucks. The base jaws are precision ground and lapped to achieve high repeating accuracy and minimize jaw lifting as the chuck clamps. PPC chucks can be actuated by either a hydraulic or pneumatic cylinder. Their modular design permits PPC chucks to be adapted to any machine spindle and draw tube configuration.

PPC chucks feature a patented
open center design with seperate actuators mounted to a piston connected to the draw tube adapter.
