Taper precision<=AT3 and part of the standard size are tested by Diebold standard inspection tools which made in Germany.

Surface:Nickel coating and polishing nickel coating.

We are specialized in researching,producing and developing many kinds of collets,CNC Machine Tool Holder, ER nuts,ER spanners,machine vises,fasteners etc. With high quality and full varieties.

Surface roughness is reduced ,precision stability improved.
The collet chuck surface uneven texture,after polishing,the surface roughness can be leveling ,smooth and shining surface.At the same time filling surface pores scratches and other surface defects,thus improve the fatigue strength,corrosion resistance increase.

Don't influence precision.
Chuck surface is coated ,the layer is evenly ,Chemical plating solution dispersion degree of almost 100%,nickel layer is thin ,thickness is about 3u-5u,this special coating can reduce Spindle abnormal wear and tear ,Don't influence precision.

Anti-rust,anti-corrosion,durability better.
Coating adhesiion 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 actiions ,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 .
