Servo press, also known as electronic press, is different from hydraulic press as follows:

1、 Driving method: Zhoumi numerical control electronic press is driven by servo motor to assemble high-density ball screw, and the pressure is directly converted from the torque output of servo motor; while general hydraulic press is driven by motor to drive oil pump, change direction through reversing valve, and then perform pressure operation by hydraulic cylinder, and the pressure passes through oil pipe and valve body, with certain loss.

2、 Energy saving and environmental protection: Zhoumi CNC electronic press adopts servo motor. In its standby state, the motor does not rotate, and in the process of pressing, the speed and power change. And the general hydraulic press, the motor has been running in the standby process, need to consume a certain amount of electricity, in the work is also constant speed rotation, power consumption will be higher. Compared with the general motor and servo motor, the noise will be larger.

3、 Precise control: careful numerical control electronic press, in a certain range, can arbitrarily set multi stroke speed, accurate displacement stop, accurate position stop, accurate pressure stop, etc. However, the general hydraulic press is affected by the tightness of pipeline, valve body and cylinder block, so it is impossible to operate with high precision, and many of them are realized by means of mechanical limit. If it is close to the precision of Electronic Press, the equipment cost will be much higher than that of electronic press, and the operation will be more complicated.

4、 Efficacy: Zhoumi electronic press has the following functions:

A online press fit quality judgment: the curve of press fit force and displacement in the whole process can be displayed on the LCD touch screen; the whole process operation can automatically judge whether the product is qualified at any stage of the operation, and remove the defective products in real time, so as to realize online quality management;

B. the pressing force, pressing depth, pressing speed and holding time can be input on the operation panel with friendly interface and simple operation;

C can customize, store and call 100 sets of press fitting programs: Seven press fitting modes are available to meet your different process requirements;

D through the external port connected to the computer, the press fit data can be stored in the computer to ensure the traceability of the product processing data and facilitate the production quality control;

E because the machine itself plays the role of accurate pressure and displacement control, so there is no need to add hard limit on the tooling. When processing products of different specifications, it only needs to call different press fitting procedures, so it can easily realize multi-purpose and flexible assembly of one machine.

Hydraulic press:

1. Low safety and high noise.

2. High power consumption and pollution.

3. It is difficult to control the cycle density.

4. Quality control is not easy.

5. The cost of mold making is high.
