BT50-Er Collet Chuck

Comprehensive inspection way of chuck

#7:24 taper precision ≤AT3And part of the standard size are tested by

standard inspection tools which made in Germany;

#Surface of the clamping inner hole is grinding by high speed inner-aperture grinder. and inspect by standard pneumatic measurement instrument; the big end contact area rate is above 90%;

#Shank thread is inspected with 4h level thread ring gauge. and the nut is inspected with 4H level thread plug gauge, the quality guaranteed;

#Run out of the inside shank Bone: <0.002(The length of the shank 100L)

#Coaxiality 5u:Shank run out≤0.002;

Equip≤0.005. The highest comprehensive run out point is no more than0.005(≤0.005mm collet clamping interchangeable with any integrated shank run out does not exceed the highest accuracy 0.008mm);

#Dynamic balance:We can do G2.5 20000一50000rpm according to clients demands.

Cryogenic treatment

1.-185℃ long cryogenic.nearly all of the residual austenite into martensite

2.Carbide precipitation of Nanoscale particles,increasing the hardness

and toughness 3.Reducing residual stresses

4.Wear resistance significantly improved

#20h long shaping hot aging to remove the residual internal force during grinding

Thermal aging processing

20h long stereotyped thermal limitation removal

of grinding residual of grinding residual stress.
