OZ Collet Drilling

DIN6388B EOC Spring Collet, 65Mn Material oz collet drilling and milling


DIN6388B EOC or OZ COLLET , also known as spring collet, is mounted on a drill milling machine, drilling and milling chuck, its function is to clamp drill cutter or knife. Er flexible collet is currently the most used. EOC Collet Its stable performance, high accuracy by the majority of manufacturers trust. EOC Collet All products are precision grinding, in line with the German DIN 6499 specifiCATEEions precision manufacturing.



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.



eoc collet

DIN 6388B EOC OZ collet is a type of collet used in machining operations. It is a precision tool holding device that is used to securely hold a workpiece or tool in a machine tool, such as a lathe or milling machine. The DIN 6388B EOC OZ collet is designed to fit specific tool holders or spindles that are also designed to the DIN 6388B standard.

The "EOC" in the name refers to the type of collet closure mechanism used in this collet. The EOC collet closure mechanism is a spring-based system that allows for quick and easy tool changes. The "OZ" in the name refers to the size or diameter range that this collet is designed to hold.

The DIN 6388B EOC OZ collet is commonly used in various industries, including automotive, aerospace, and general machining. It offers high precision and repeatability, making it suitable for appliCATEEions that require tight tolerances.

Overall, the DIN 6388B EOC OZ collet is a versatile tool holding device that provides secure and accurate clamping for machining operations.
