The rapid change system EWS-Varia allows to set-up a modern CNC lathe or a turning milling center – and this flexibly.
A tool change will just take 20 seconds, which is an unbeatable argument especially in small batch productions whenever it is about reducing the set-up time and thus increasing the productivity.
The advantages, however, are also evident in large batch productions. Preset twin tools lie at the machine, thus significantly reducing the down-times.
A further advantage is provided by the variety of adaptations; so the optimal tool clamping can be selected for each operation.
The inserts available include:
- Collet chuck holders
- Weldon/Whistle Notch
- Milling arbors
- Morse tapers
- Hydro extension
- Shrink adaptations
The most important advantage is certainly created by the easy handling.
The inserts can be changed with just one hand without counter pressure by the spindle. The holders are released from the machine by a mechanically impinged ejector system, so that agglutination by coolants will no long occur.
This solution reduces the risk of injury of the machine operator to nearly zero.
EWS-Varia is available for nearly all tool holders from VDI25 and BMT55, respectively.
