PRODUCT FUNCTION

1. Strong clamping force

2. Tough toughness and toughness
Collet hole through the precision grinding machine
Material: high-carbon bearing steel, in the heat treatment, with a tough hardness and toughness, and good flexibility and longer life
Hardness 46-50HRC
3. Exquisite processing technology
● Cryogenic treatment
1, -185 ℃ super-long cryogenic treatment, so that nearly all the retained austenite into martensite;
2. precipitation of nano-carbide particles to increase the hardness and toughness;
3. Reduce the residual stress;
4. Significantly improve wear resistance.
 
Aging processing
≥ 100h ultra-long set to remove the heat aging residual stress grinding process.
