Multi-blade Collet Chuck LZK-S
"The multi-range collet system of SwissChuck."
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.
SwissChuck's collet system – the insider tip for efficient production!
What is not possible with widely used collet systems can be easily solved with the SwissChuck collet system. The large clamping range of a single interchangeable collet enables the overlapping of shoulders on workpieces. Your machine setup thus becomes more flexible and a change to jaw chucks and the resulting change-over times often remain unnecessary. SwissChuck offers a comprehensive standard program. If no suitable collet chuck is available, customized special collets can be supplied.
LZK-S collet chuck for external clamping
Clamping task:
Stepped cylindrical shaft, flange end must be over-gripped
- Radial run-out ≤ 0,01 mm
- Clamping ø up to 162 mm (chuck LZK-ES)
- Low deformation clamping of thin-walled workpieces
- Large through-hole – suitable for bar material
- High RPM
- High clamping force
- Low loss of centrifugal force
- Impervious to contamination
