Spring Collet 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.
ER sealed collet is a type of collet that is used in machine tools, such as milling machines and lathes, to hold and secure cutting tools or workpieces. It is called "sealed" because it has a rubber or plastic sealing ring that prevents coolant or debris from entering the collet and contaminating the tool or workpiece.
Spring collet, on the other hand, refers to the mechanism used in the collet to grip and hold the tool or workpiece. It consists of a series of spring fingers that exert radial pressure on the tool or workpiece, ensuring a tight and secure grip.
Together, the ER sealed collet combines the sealing feature with the spring collet mechanism, providing a reliable and efficient tool holding solution that is suitable for applications where coolant or debris is present.
