Liquid nitrogen cryogenic treatment

1、single time, 12 hours. -185℃. and ultra long cryogenic treatment make the nearly all retained austenite change to martensite.

2、 the precipitated nano carbide particles increase the hardness and toughness of the material.

3、 remove the internal stress of the residual material.

4、 after cryogenic treatment, the wear resistance of products is significantly improved, and the accuracy and service life of repeat clamping can be increased by about 50%

The concave platform in front of the chuck cone is designed to prevent dust from entering during work and improve efficiency

Strong clamping ability,wide clamping range,high precision

Product Installation

Collet in the process of the installation of the lock nut,collet locking nut must tilt angle,and then gently on a lock card lock
nut inside.
