Description
Ball Bearing ER Collet Chuck Nut, Balanced To 18,000 RPM at G2.5
Features
- The built-in ball bearing sliding module ensures uniform force distribution when the collet is compressed under ultra-high load, allowing the collet to contract evenly, maintaining its precision and enhancing its contracting force.
- Bearing sliding provides strong stability, reducing noise and vibration, and when paired with the chuck, it offers greater stability and higher precision.
- The strong clamping force effectively prevents nut wear and tool breakage, improving machining efficiency.
