Product Category
ER Collet & Clamping
Concentric clamping adaptors and collets optimized for high-speed spindles and vibration-free cutting.
Engineering Overview
We offer high-accuracy ER collets, clamping nuts, and pull studs constructed from premium spring steel with precision cryogenic heat treatments. This ensures maximum clamping force and minimizes radial runout, preventing micro-chipping on delicate solid carbide cutting edges during high-speed milling.
Key Manufacturing Advantages
- Precision concentricity according to DIN6499 parameters.
- Rust-resistant passivation treatment for coolant environments.
- Full collet bore contact holding force.
- Extended collet lifecycle with high structural elasticity.
