The design of the convex plate in front of the CSK collet can prevent dust and chip getting into the collet when processing, prolong the collet service life.
Surface of CSK collet employ the [environmental protection"-special coating surface treatment, improved the hardness and endurance of the collets` surface. The collet tend to be cleanness better, accuracy stable, and the surface more smooth, antirust, feel comfortable and appearance nice.
Furthermore, the precision grinding for inner hole, outer circle and end face up to Ra0.4. And the cone angle of CSK collet is designed as 8°that improves the clamping force and anti seismic performance.
Comprehensive features of CSK High speed
collet:
1. Japanese Material: JIS-SUJ2;
2. Hardness: 46-50 HRC;
3. Nickel coating surface: - Antirust;
-Improve the hardness and endurance of the
surface;
-Cleanness better, Accuracy stable;
-Surface more smooth, feel comfortable, appearance nice.
4.
Cryogenic treatment:
(1).-196°long
cryogenic, nearly all of the residual austenite into martensite;
(2).Carbide
precipitation of Nanoscale particles, increasing the hardness and toughness;
(3).Reducing
residual stresses;
(4).Wear
resistance significantly improved.
5.
Thermal aging processing
Removing of
residual internal stress by super-long heat aging.
Comprehensive features of CSK –C type (Oil Hole type) High speed collet:
1. Japanese Material: JIS-SUJ2;
2. Hardness: 46-50 HRC;
3. Using the difference of grooves
to reach round sealing and only central water discharge;
4. Apply to clamp he central water
discharge cutter;
5. Non-standard holes can be
customized.
