1.The material is 20CrMnTi/JIS-SCM415,the hardness is 56-60HRC,the carbon depth >0.8mm
3.Chuck shank do -196℃ super-long cryogenic treatment and thermal aging treatment.
4.Default of dynamic balance standard ,G6.3 18000rpm.Precision dynamic balance G6.3 12000RPM.Surface coating processing .Iproove cleanness,precsion more stable ,surface more smooth,feel more comfortable and appearance nicer. Chuck surface is coated ,the layer is evenly ,Chemical plating solution dispersion degree of almost 100%,nickel layer is thin .This special coating can reduce Spindle abnormal wear and tear.Don't influence precision .
5.We can to figure to sample processing ,and perfect after-sales service and technical support.
