ER32 Lock Nut for ISO/HSK DIN 6499 Holders
Index: 932GHCOS
A precision lock nut designed for holders and milling chucks with ISO and HSK mounting, compliant with DIN 6499 standard. It is used for securely and safely seating ER32 collet chucks in the body of the holder. The carefully balanced and precisely manufactured design ensures even clamping pressure on the collet, minimised axial runout, and safe operation on CNC machining centres and milling machines at high rotational speeds.
Key Technical Parameters and Properties:
- Compliance with DIN 6499: Guarantees an ideal fit for standard ISO and HSK holders as well as ER32 collet chucks.
- Precision Thread: Ensures smooth tightening and uniform transfer of clamping force to the collet chuck.
- High Rotational Accuracy: Accurate grinding and balancing eliminate vibrations, protecting the spindle bearings and tool from wear.
- Durable Steel Construction: High resistance to wear and deformation under high tightening torques.
Application and Purpose:
Component designed for securing ER32 collet chucks in standard ISO and HSK milling holders on CNC machining centres and stationary milling machines.
