The ER32 20 mm Collet is a critical interface component for modern CNC machining centers, engineered to provide secure, precise, and vibration-free clamping for cutting tools. Manufactured in accordance with the DIN 6499 (ISO 15488) international standard, this collet ensures universal compatibility and high geometric accuracy. When tightened via the collet nut, the flexible segments close radially to grip the cylindrical tool shank with uniform force, minimizing axial and radial movement even under high-speed or heavy-duty cutting conditions.
Technical Specifications and Durability:
Produced under Mermak CNC engineering standards, this collet is crafted from high-strength alloy carbide steel. Optimized heat treatment processes, including hardening and tempering, achieve a surface hardness of HRC 44-48, ensuring exceptional wear resistance and long-term performance. It is ideal for CNC milling, turning, drilling, and tool manufacturing applications.
Key Advantages:
- High Run-out Accuracy: Offers extremely low run-out (3-5 μm in premium series), ensuring minimal deviation from the rotation axis. This extends tool life, balances cutting forces, and enhances surface finish quality, making it essential for complex mold making and precision parts.
- Optimal Clamping Force: The internal conical design and flexible segments provide uniform pressure distribution, preventing tool slippage at high RPMs (20,000+ RPM). This enhances operational safety and minimizes chatter marks on the workpiece.
- Universal Compatibility: Compliant with DIN 6499/ISO 15488, this collet is compatible with a wide range of CNC milling, turning, and drilling machines. The 20 mm nominal diameter accommodates standard end mills, drills, and reamers with a 0.5 mm clamping range.
