One, the driving method: perimeter CNC electronic press is driven by a servo motor high perimeter ball screw pressure equipped with homework, the pressure is directly from the servo motor torque delivery and change for the; Unusual hydraulic presses are driven by the motor oil pumps, end of the reversing valve to change the target and then by the hydraulic cylinder to implement the pressure of homework, the pressure of its beginning to the end of the tubing and the body of the valve, there is a The pressure of the oil pipe and valve body, there is a certain loss.
Second, energy saving and environmental protection: close CNC electronic press is selected servo motor, its standby mode, the motor is not turning, and in the pressure loading process, the speed is shifted, the power is also shifted. Unusual hydraulic press, standby process motor has been turning, in the work is also a constant speed rotation, power consumption compared to some higher. Compared with the servo motor, the noise will also be larger.
Three, accurate control: circumscribed CNC electronic presses, within certain boundaries can be arbitrarily set multi-stroke speed, accurate displacement stop, accurate in place to stop, accurate arrival pressure stop. The unusual hydraulic press is affected by the pipeline and valve and cylinder block sealing, it is not possible to have a very high precision control, and many of them are completed with the help of mechanical limits, if you want to close to the precision of the electronic press control, the cost of equipment will be much higher than the electronic press and control is more complex.
