ERC Collet Oil Hole for CNC tools DIN6499

Leading produce ER collet, ER collet chuck, CNC machine tools, milling machine tools, and other tool holders around 20years.

DIN6499B Standard High Precision 0.015mm-0.005mm ER16C ER20C ER25C ER32C ER40C Collet ER Collet is made of high quality SUJ2 material, with hardness of HRC45-50. We produce alll size of 1mm-20mm ER32 collets, and full range of ER11C ER16C, ER20C, ER25C, ER32C, ER40C collets. We have exported to humorous countries, and establish good cooperate relationship. Accuracy is from 0.005mm to 0.015 for your reference. We also manufactures kinds of CNC machine tool accessories including collet chucks, pull studs, retention knob, spanner and wrench and other related products.

ER32C Spring Collet
1) Runout of our ER collet are within 0.005mm-0.008mmm.

3) Made of high quality steel:JIS-SUJ2.
4) Packing:Inner packing is plastic or paper box,the outer packing is cartons.
5) We normally supply three kinds of accuracy: first accuracy 0.005mm,second accuracy 0.008mm. and third accuracy 0.015mm.the highest accuracy is 0.005mm.
6) Inspection:100% collet inspection.

Cryogenic treatment

1) -196℃,and ultra long cryogenic treatment make the nearly all retained austenite change to martensite.
2) the precipitated nano carbide particles increase the hardness and toughness of the material.
3) Remove the internal stress of the residual material.
4) after cryogenic treatment,the wear resistance of products is significantly improved,and the accuracy and service life of repeat clamping can be increased by about 50%.
