Function

SK Collet

High-speed, high-precision SK collet
● Material: Imported material SUJ2;
● Hardness: HRC46-50;
● Extremely deep cryogenic treatment and thermal aging treatment in the process to improve the accuracy and dimensional stability;
● 4 ° semi-cone angle of collet design, more clamping force, improve the seismic performance;
● The boss on the front of the collet is designed to prevent the entry of dust and chips and prolong the service life.
● The inner hole is polished many times, up to Ra0.4, the mirror effect;
● Surface coating treatment to improve the surface hardness, wear resistance, improve cleanliness, more stable accuracy, the surface is more smooth, rust, corrosion better, feel more comfortable, more beautiful appearance.
