Chong De is a manufacture in R&D, production, sales and services with ISO9001 certificate. The main products are precision tool holder, clamping collets, pull stud, nut, spanner and other machine tool accessories with the standards of ISO, DIN, ANSI / ASME, JIS and local GB, etc.
1. The unique design of nut: high speed cutting, reduce
drag and cutting noise and improve work efficiency, Balance for G2.5 20000rpm.
2. General purpose high speed, high precision machining, cutting effect is
good.
3. Surface" environment protection ", special coating surface
treatment, improve the hardness and endurance of the surface, cleaness better, accuracy stable, surface.
4. Higher system accuracy.
5. Higher system stiffness.
◆Coating adhesion strong, enhance hardness, and anti-rust better in different surroundings, such as acid, alkali, ammonia, salt etc.
◆Overall nickel coating , including inside and outside cone, even if you do not take any anti-rust actions , it will not rust either, don't influence processing precision and spindle. Improve cleanness, precision more stable, surface more smooth, feel more comfortable and appearance nicer .
