Component Specifications

Definition
A tool chuck or collet is a specialized clamping mechanism used in machine tool spindles to hold cutting tools with high precision and concentricity. It provides rigid tool retention while allowing quick tool changes, ensuring accurate machining operations in industrial manufacturing.
Working Principle
Works through mechanical compression, where tightening the collet nut causes the slotted collet to contract uniformly around the tool shank, creating a secure friction-based grip without damaging the tool surface.
Materials
Typically made from hardened steel (AISI 4140/4340), stainless steel, or carbide-coated variants for wear resistance. Collets often use spring steel for elasticity.
Technical Parameters
  • Max RPM 15,000-40,000
  • Grip Range 0.5-32 mm
  • Shank Type BT, CAT, HSK
  • Collet Type ER, TG, DA
  • Clamping Force 2,000-10,000 N
  • Runout Tolerance <0.003 mm
Standards
ISO 15488, DIN 6499

Frequently Asked Questions

What is the difference between a chuck and a collet?

A chuck typically uses jaws to grip tools and can accommodate various sizes, while a collet is a sleeve-like device that provides more precise concentricity for specific tool diameters.

How often should tool chucks be maintained?

Regular inspection every 500 operating hours, with cleaning and lubrication of moving parts. Replace collets showing wear or reduced gripping force.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
