SK40-ER20-70L Er Collet Chuck CNC Machine Tool Holder
SK40-ER20 Collet Chuck are mainly used for CNC machine system. SK-ER tool holder serves an ultra precision. High Precision SK shank Tool Holder ,balanced G6.3 or G2.5 For choose,With DIN6499 collet chuck can be straight shank cutter clamping various sizes.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.
SK40 ER TOOL HOLDER SK40 High Precision Tool Holder SK 40 Er Collet CHUCK
SK Tool Holders for mechanical spindle and cutting tool and other accessory tool connection. Is a simple, popular spindle shank connection standard, mainly SK30 SK40 SK50... Etc.. Mold industry, and high-speed engraving machine, used more.
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.
Comprehensive inspection way of chuck:
1.7:24 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 100L);
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:SK30/40:G2.5-20000RPM;SK50:G2.5-15000RPM;
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;
