OLICNC® presents its High Precision ER Collet series, engineered to meet the diverse demands of CNC machining applications. Crafted from 65Mn spring steel, these ER collets are designed to deliver exceptional durability, wear resistance, and fatigue strength. Each collet undergoes high-frequency quenching treatment and is finished with precision surface grinding and polishing, ensuring superior accuracy and extended service life.
Precision Grades:
Our ER collets are available in multiple precision grades to cater to a wide range of machining requirements. Grade Ⅰ offers ≤ 0.003mm precision, making it ideal for ultra-high-precision tasks. Grade Ⅱ provides ≤ 0.005mm precision, suitable for high-precision applications. Grade Ⅲ delivers ≤ 0.008mm precision, perfect for medium-precision operations. Grade Ⅳ ensures ≤ 0.01mm precision, while Grade Ⅴ offers ≤ 0.015mm precision for general-purpose machining.

High-Frequency Quenching Treatment:
To enhance durability and performance, our ER collets undergo high-frequency quenching. This process increases the hardness and wear resistance of the collets, ensuring they maintain their structural integrity and precision even under prolonged use.

Surface Grinding and Polishing:
Each collet is meticulously ground and polished to achieve a smooth surface finish. This treatment not only improves the collet’s performance but also minimizes wear during operation, ensuring consistent accuracy and a longer lifespan.
