Hydraulic presses mainly use a control system where an AC servo motor directly drives a hydraulic pump. The system has the following features.
- The motor operates in rotation speed that matches the requirements made by a machine, realizing a significantly reduced energy consumption and noise level.
- A compact machine design thanks to the reduced capacity of a oil tank.
- The motor can be reduced in capacity since only necessary amounts of pressure and flow are supplied.
- Fewer control valves that make hydraulic circuits more simple.
- Energy saving
- Low noise
- High performance
Press brakes must finish a product with correct angles and dimensions.
By using a linear servo valve, it allows to control positions and loads(pressure) with a high degree of accuracy during processing, making high-quality products to be easily manufactured.
- High accuracy
- High response
