Product Description

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.

Special Force has developed a new process quenching treatment for collets, which has a decisive influence on product accuracy, service life and stability.
Quenching is a high-frequency aging treatment added to the heat treatment, -196℃ degrees cryogenic treatment, these are not reflected in the appearance, but have a decisive impact on the service life and stability of the product. Processing technology, full-line CNC internal hole grinding machine, compared with the products processed by ordinary internal hole grinding machine, the inner hole straightness is better, the finish is better, and the precision is needless to say.

ER11C/ER16C/ER20C/ER25C /ER32C/ER40C/ER50C Collet (OIL HOLE TYPE) Steel Sealed Collets, also known as spring collet, is mounted on a drill \ milling machine, drilling and milling chuck, its function is to clamp drill cutter or knife. Er flexible collet is currently the most used. Its stable performance, high accuracy by the majority of manufacturers trust. All products are precision grinding.

New technology  brand new packaging , High accuracy ,quality ,durability and stability.

High temperature treatment, hardness uniformity.  Full bright appearance, good elasticity.

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%.
