Product Description

CNC lathe parts ERG tap spring collet

Quenching ERC Collet New brand packaging, new on-line, new technology, precision, quality, durability, stability, stability, ERC  COLLET(Oil Hole Type).
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.
CNC lathe parts ERG tap spring collet
1) Runout of our ERG collet are within 0.005mm/0.005mmm.
2) ER11C,ER16C, ER20C, ER25C, ER32C, ER40C and ER50C collet.
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 0.008mm.The highest accuracy is 0.005mm.
6) Inspection:100% collet inspection.

The trait of ER Collet

Kinds of ER Collet

The Size of ER Collet

New technology  brand new packaging , High accuracy ,quality ,durability and stability.
High temperature treatment, hardness uniformity.  Full bright appearance, good elasticity.

The production process of ER Collet

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%.

1.Package: Plastic boxes and also can pack according to your requests.
2.Delivery time:Sample within 7 days and others 35 days.
