Rotary Power Chuck Introduction

It used to be complex for users to convert a manual chuck system to a power one, since setting up a hydraulic system not only is expensive, but also is troublesome. JATO Rotary Power Chuck is specially designed to help users to set up a power workholding system in a low cost way. With a built-in rotary cylinder, JATO's Rotary Power Chuck allows users to easily and quickly set up a power workholding system, and saving cost on purchasing an additional rotary cylinder. JATO Rotary Power Chuck also has quick-change jaw/collet design, helping you to cope with parts of various dimensions.

Rotary Power Chuck comes with both air collet chuck and hydraulic collet chuck models that range from small sizes to large ones, giving users more options to choose from. Rotary Power Chuck now is widely applied to convert manual lathe to semi-auto ones with power workholding system, or is applied to build all kinds of special purpose machines.

  • Air/Hydro cylinder is built-in. No need for extra rotary cylinder.
  • Repeatability for jaw type power chuck: 0.040mm-0.080mm.
  • Aluminum alloy chuck body, light-weighted, good heat dispensation.
  • Allows non-stop operation when loading parts.
  • Widely applied to convert manual lathe into powered ones.
