EOC OZ Collet For Milling Chuck Holder , Used for boring,milling,drilling,tapping,grinding and engraving operation etc.Adopt high strength special material after quenching ,through cryogenic treatment ,the product performance is stable ,wear-resisting and durable. High clamping force ,high precision .Strong substitutability.
Eoc Spring Collet SpecifiCATEEion
● EOC Collet Material: 42CrMo;
● Eoc Milling Collet Hardness: 46-50HRC;
● Precision Collet Grinding within the hole several times, up to
Ra0.4, played a mirror effect;
● ,Eoc 25 Collet Cylindrical blank sockets adopt grinding
processing technology, more suitable for high-speed processing;
● Cylindrical and end face grinding, up to Ra0.4, play a mirror
effect;
● Surface "green" special coating treatment, improve the surface
hardness, wear resistance, improve cleanliness, more stable
accuracy, the surface is more smooth, rust, better corrosion
resistance, feel more comfortable and more beautiful appearance.
● Spring Collet Cryogenic treatment
1, -185 ℃ super-long cryogenic treatment, so that nearly all the
retained austenite into martensite;
2. precipitation of nano-carbide particles, 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.
DIN 6388A OZ collet is a type of collet used in machining and tooling appliCATEEions. It is designed to hold cylindrical workpieces securely in place during machining operations. The collet has a cylindrical shape with a series of evenly spaced slots or grooves on its outer surface. These slots allow the collet to expand and contract, enabling it to grip and release the workpiece. The DIN 6388A OZ collet is commonly used in milling machines, lathes, and other machining equipment. It is available in various sizes to accommodate different workpiece diameters.
