1.SK1collet made of 65Mn material, it has high strength, certain flexibility and plasticity; under the same surface state and complete hardening, it has long life, high precision, low calorific value, high speed, high rigidity, low Noise, high wear resistance, fatigue limit and high stability.
2.Heat treatment + cryogenic treatment, the chuck has high strength, good toughness and plasticity - 187 ℃ ultra-long cryogenic treatment, transforms retained austenite into martensite and precipitates nano-scale carbide particles, improves hardness and toughness, reduces residual stress, Enhanced wear resistance.
3.Precision technology, stable and reliable, high precision, simple fixture 8" half cone angle design, greater clamping force, wide clamping range.
