Efficient changing of milling tools for lathes

Increase operating ratio of machine with the quick change system!

The quick change system Varia

It is available for nearly all tool holders.
A tool change will just take short time! Reducing the set-up time and increasing the productivity!





Tool change "without" the quick change system

The tool is replaced using a spanner in the machine, it may be difficult to replace the tool if the inside of the machine is too narrow or too far from the changing tool position.

Since the machine will stop during the tool change, productivity will change depending on workability.




Tool change with the EWS Varia

Simple and quick change the tools.

Quick change through only one clamping point.
Changing time is less than half that of the usual method.
