1.The material is 20CrMnTi/JIS-SCM415,the hardness is 56-60HRC,the carbon depth >0.8mmPrecision taper<=AT3.Chuck shank do -196℃ super-long cryogenic treatment and thermal aging treatment.Default of dynamic balance standard ,G6.3 18000rpm.Precision dynamic balance G6.3 12000RPM.Surface coating processing .
2.proove 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 .
3.We are specializing in the production of this, we can to figure to sample processing, and perfect after-sales service and technical support. Looking forward to your cooperation!
