ER20 10 mm Collet Tool Holder
Industrial Automation Components | Superior Performance Series
The ER20 10 mm collet is a critical interface component for CNC machining centers, milling machines, lathes, and specialized machine tools. It ensures precise and rigid connection of cutting tools to the spindle. This collet directly influences the concentricity between the tool axis and the spindle axis, playing a decisive role in the geometric accuracy, surface finish, and final part quality of your machining operations.
The ER collet system operates by utilizing an elastic structure placed in a conical seat, which is compressed axially by the collet nut to generate radial clamping force. This mechanism pushes the tool shank against the inner conical surface of the collet, ensuring stability even at high speeds and under heavy cutting forces. The tolerance between the collet inner diameter and the tool shank is vital for homogeneous force distribution and runout precision, contributing to extended tool life and minimized vibration.
Manufactured from high-quality alloy steel, this ER20 10 mm collet has undergone specialized heat treatment processes to provide excellent wear resistance, toughness, and high strength against deformation. It is designed to withstand repeated clamping cycles and centrifugal forces generated at high RPMs. This collet is a global standard for industrial automation and precision machining, suitable for tools with a 10 mm nominal diameter.
Key Advantages
- Minimum Runout Tolerance: Provides high geometric accuracy, ensuring uniform load distribution on the cutting tool, which extends tool life and reduces the need for secondary finishing.
- Optimized Torque Transfer: When tightened to the correct torque, it provides maximum rigidity, minimizing tool slippage or vibration during high-speed operations.
- High Durability: Constructed from premium alloy steel, it offers superior resistance to the harsh conditions of industrial environments, including dynamic loads and high-speed rotation.
