High-precision collet chuck LZK

The collet chucks are designed for demanding clamping geometries and varying workpiece diameters. The high-precision lamella clamping technology makes it possible to cover a clamping range of several millimeters with one interchangeable collet. Due to the perfect clamping geometry (parallel clamping) over the entire clamping range, a sustained concentricity of better than 0.01mm can be guaranteed. For example, with the chuck type LZK-BS, the clamping range from ø2.5 to 42.5 mm can be covered with only seven interchangeable collets. In addition to reduced stock-keeping and the associated low investment costs, change-over times are reduced, and flexibility in production is increased. Functions & Fields of Application • Lamella-change-over collets • Axially fixed clamping position • Actuation utilizing force clamping cylinder • In the main for turning and grinding operations • Advantages • Parallel clamping across the entire stroke • Large clamping range per change-over collet • Minimal change-over times • Stable and robust chuck • High RPM • Suitable for thin-walled rings (number of clamping lamella) • Over-grip clamping possible Accuracy across the whole clamping range! The high-precision lamella clamping technology makes it possible to cover a clamping range of several millimeters with one interchangeable collet. Due to the perfect clamping geometry (parallel clamping) over the entire clamping range, a sustainable concentricity of better than 0.01mm remains guaranteed.
