The optimum cutting speed for standard appli-
cations is 20-25 m/s (values in bold type).
You can set the correct wire cutting speed with
the correct choice of litre flow rate (with multi-
stage drives) and the hydraulic motor. In this
way you can achieve:
- Optimum sawing performance
- The best service life for the wire
- Less wire cracks

If there is a lot of steel reinforcement or if hard
aggregates are found the wire cutting speed
should be reduced.

Switch back by one stage
This causes the wire cutting speed to be
reduced by 4-5 m/s.

With single-stage drives, the hydraulic motor
can be changed (use larger motor).
This causes the wire cutting speed to be
reduced by 4-5 m/s.
