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 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.
