Self-Contained Power Chuck. No need for an extra rotary actuator.
Easy mounting, collet and jaws can be changed rapidly to set the gripping system.
Aluminum alloy chuck body, light-weighted, good heat dispensation.Widely applied to convert manual lathes into powered ones. Refer to the following figure.
Don't spray the cutting fluid to the collet directly.
JA7-44/JH7-44 type collet adopts the 2 times force design and the workpieces can be gripped by extanding.
Introduction
It used to be complex for users to convert a manual lathe into one with power workholding device since setting up a hydraulic system is quite troublesome.
NTH Rotary Power Chuck is specially designed to help users to set up a power chuck in a low cost and easy way. With its built-in rotary actuator, the Rotary Power Chuck can be installed and start working in less than 20 minutes.
Rotary Power Chuck comes with both air chuck and hydraulic 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 lathes to semi-auto ones with power workholding system, or is applied to build special purpose machines.
