The inner hole is grinded many times, reaching Ra0.4, which has a mirror effect.
Grinding process is adopted for the hollow slot of cylinder clamp, which is more suitable for high-speed machining.
The outer circle and the end face can be grinded many times, reaching Ra0.4, which has a mirror effect.
Surface "environmentally friendly" special coating treatment, improve surface hardness, wear resistance, improve cleanliness, more stable accuracy, smoother surface, better rust and corrosion resistance, more comfortable feel, more beautiful appearance. Mainly used in various drilling, milling and lathe.
Cryogenic treatment
1. The ultra-long cryogenic treatment at - 185 C transforms nearly all residual austenite into martensite.
2. Precipitated nano-carbide particles increase hardness and toughness.
3. Reducing residual stress;
4. The wear resistance is improved significantly.
Aging treatment
Removal of residual internal stress during grinding by over 100 h super-long heat aging.
Introduction of ER-UP High Precision Spring Clamp:
High precision spring chuck combines the advantages of DIN6499/ISO15488A and B standards. This kind of spring chuck is mainly used in high-speed cutting which needs good radial runout error. Good radial runout can prolong tool life.
T.I.R. (Radial Runout Error) = 8 um in the whole clamping range
The clamping diameter ranges from 1 mm to 36 mm
The clamping range is equivalent to the standard spring chuck.
