BT30-ER16-70L ER Collet Chuck CNC Machine Tool Holder

ChongDe is a manufacture in R&D,production,sales and services with ISO9001 certificate.The main products are precision tool holder,clamping collet,pull stud,nut,spanner and other machine tool accessories with the standards of ISO,DIN,ANSI/ASME,JIS and local GB,etc.
Attaching importance to the research and products,we employs many experienced and skilled technicians,so that precision machining can be made according to samples or drawings.

BT-ER Collet Chuck: Mainly used for clamping of straight shank tools and tools such as drills, milling cutters and taps.

BT-ER Tool Holders Spring chuck model: divided into ER8, ER11, ER16, ER20, ER25, ER32, ER40, ER50.

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 adhesion 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.
