Compared with pure electric drive, it has strong hydraulic power and durability, and a compact design eliminates external pipelines. At the same time, the system is directly installed on the oil cylinder, which is cleaner and leak free.

The system converts the electrical signals in the CNC controller into mechanical linear motion. To complete this motion, signal transmission is carried out between the CNC controller of the machine tool and the motor drive controller. The synchronous oil cylinder controls the tracking of work progress and rapid operation according to the pre-set working curve. Use a variable speed servo pump unit to drive and control the position of the bending tool and the bending force during the bending process.

1、 Principle of double servo Press brake

The working process in which pressure is generated by the hydraulic system and transmitted through the upper and lower molds, ultimately obtaining the required material shape.

2、 Correct use of servo CNC press brake bending machine

1. Firstly, turn on the power supply, turn on the key switch on the control panel, and then press the oil pump to start.

2. For stroke adjustment, attention must be paid to the stroke adjustment when using the CNC Press brake, and the test run must be conducted before bending. When the upper die of the CNC press brake bending machine descends to the bottom, a clearance of plate thickness must be ensured, otherwise the die and the machine will be damaged.

3. The selection of bending groove generally requires selecting a groove 8 times the width of the plate thickness.

4. The adjustment of the rear stopper generally includes electric quick adjustment and manual fine adjustment, using the same method as the shearing machine.

5. Step down the foot switch to start bending. The Press brake is different from the shearing machine and can be released at any time. Release the foot and the CNC Press brake will stop, and then step on it and continue to go down.
