Hydraulics for machine tools
Clamping, tool changes and precise movements demand stable pressure and intensive duty cycles.

Industry needs and our answers
Intensive cycles
Three-phase motors in S1 duty or S3 with a high duty ratio (75% for the cutting blades), sized for the machine’s actual cycle rate.
Repeatable pressure
The relief valve arrives set to the required value, for example 130 bar: clamping stays the same cycle after cycle.
On-board controls
Solenoid valves integrated on the manifold and a gauge with isolating valve: no loose piping, compact logic.
Footprint and protection
Steel reservoirs of about 15 l with level indicator, IP55 motors: units that mount directly on the machine.
A real case: Two-valve power unit controlling cutting blades
| Machine | control of automatic cutting blades, up and down |
|---|---|
| Controls | 2 integrated solenoid valves, glycerine-filled gauge with isolating valve |
| Motor | 0.75 kW 4-pole, three-phase 230/400 V, S3 75%, IP55, B14 flange |
| Pump | gear pump 2.1 cm³/rev, about 3 l/min |
| Pressure | 130 bar maximum |
| Reservoir | about 15 l in painted steel, with level indicator; mineral oil |
Frequently asked questions
What power pack does a machine tool need?
Usually an AC unit in S1 continuous duty, with a precisely set relief valve and a compact manifold to integrate on board. Flow and pressure are sized for clamping and movements.
Do you guarantee pressure repeatability?
Yes: the relief valve arrives factory-set to the required value, so clamping pressure stays constant cycle after cycle.
