High precision and hardness / Quenching treatment

High precision / Sturdy and durable 

Product information

Product : Common ER Collet

Specification:ER8/11/16/20/25/32/40

Material :65Mn

Precision:≤0.015

Quenching and hardening,longer life

After hot processing and high temperature treatment, the strength is relatively high, with a certain flexibility and plasticity 

65Mn spring steel  high clamping force

High quality spring steel elastic design, 

high elasticity, large clamping force

Less deformation with repeated use

-187℃ ultra-long subzero treatment

* Subzero treatment transforms residual austenite into martensite

* Precipitated nano-scale carbide particles increasehardness and toughness

* Reduce residual stress and enhance abrasion resistance
