4-jaw independent chuck K72 – Ø 1250 mm

Our high-precision 4-jaw independent chuck K72 1250 mm is specifically designed for secure and reliable clamping of a wide variety of workpieces on lathes – ideal for asymmetric, rectangular, or difficult-to-position components.

Technical specifications:

- Diameter: 1250 mm
- Design: 4-jaw independent chuck, each jaw individually adjustable
- Material: Premium cast body for maximum stability and vibration damping
- Jaws: Comes standard with hard jaws
Optional clamping jaws available per customer requirements (soft, special shapes, special sizes)
- T-slot design: Enables flexible auxiliary clamping options
- High concentricity accuracy for heavy workpieces
- Suitable for large turning diameters and high clamping forces

Mounting & Standardization

The K72 chuck is not standardized as a complete unit (no unified DIN or ISO standard for diameter, jaw geometry, or bolt patterns).
The machine interface, however, is based on common standards such as:

- DIN 6350 (center mounting)
- DIN 55029 (Camlock spindle nose, e.g., D11 / D15)

= This allows for adaptation to nearly any machine, either directly or via adapter solutions.
