HSK40E-ER20-60L CNC Collet Chucks Holders

HSK40E-ER20M-60L  Er Collet Chuck CNC Machine Tool Holder

 DIN6499 Collet Chuck HSK-ER20M  tool holder is mainly used for CNC machine system. HSK40E-ER20M tool holder serves an ultra precision. High Precision HSK shank Tool Holder, balanced G6.3 or G2.5 For choose, can be straight shank cutter clamping various sizes. Using Ball Spanner / Wrench for ER type nut. The main products are accuracy milling chuck, tool holder, HSK, BT, NT, ISO, ST, CAT type collet chuck, clamping collet, Pull Stud, nut, spanner and other machine tool accessories with the standards of ISO, DIN, ANSI/ASME, JIS and local GB, etc.

HSK40E-ER20M collet chuck, Er Collet HSK25E chuck for mechanical spindle and cutting tool and other accessory tool connection. Is a simple, popular spindle shank connection standard, mainly HSK40E, HSK63A, HSK100A……etc Mold industry, and high-speed engraving machine, used more.

Comprehensive inspection way of chuck:

1.1:9.98 taper precision≤AT3 and part of the standard size are tested by Diebold standard inspection tools which made in Germany.

2.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%.

3.Run out of the inside shank cone≤0.002(The length of the shank 60L);

4.Coaxiality 5U: Shank run out ≤0.002;Equip collet ≤0.005,The highest comprehensive run out point is no more than 0.005mm;

5.Dynamic balance:We can do G2.5 30000~50000rpm according to clients' demands.

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

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.
