Matrix, fix reference system for standard and special applications
The design has been optimised for metal-cutting machining and is ideal for work involving high machining forces.
The generous diameter of the drawbar means short distances between the references and the applied locking force, giving maximum stability and accuracy.
The inherent properties of the Matrix system truly come into their own in tough machining applications.
As well as extreme accuracy, Matrix features low construction height, ultra-precise indexing, a drawbar with through hole.
The through hole allows high/long workpieces to be sunk into the chuck for stable/rigid fixation.
Features:
- Max. work piece weight xxx Kg
- Clamping force xx kN
- Spherical rolls for clamping
- Repeatability <0.002mm ( Nano <0,001mm )
- Prepared for automatic chuck adapter
- Very low building height
