Brief introduction
CNC NT SLA Side Lock End Mill Chuck Holder, apply to the holder of a DIN1835-B with a solid surface of the cutting tool, high speed and high precision machining .
Specifications
CNC handle features
1. Material: Bearing steel, 20CrMnTi
2. Hardness: 56-60HRC
3. Taper: 7:24 taper level ≤ AT3
4. Carburization depth:> 0.8
5. Surface roughness: Ra <0.4
6. All CNC tool holders are cryogenic treatment (-196 ℃, more than 20 hours) so that the residual austenite precipitation of martensite and nano-carbide particles to improve the handle hardness, toughness and durability, reduce residual Internal stress
7. A long time heat treatment effectively remove residual stress during grinding
8. A variety of appearance: sandblasting, coating, flange appearance
