Model JS21-60 Open-type Servo Press

Main properties of product:

Model JS21-60 NC servo press is an innovation applying digital computing technology to the mechanical press. It controls the running of slide by the servo motor directly. Besides the features the mechanical press possessed, such as relatively high speed, high rigidity, high precision and high efficiency, it has the advantages such as good flexibility and technological adaptability that usually possessed by the hydraulic press, which expands the application scope of punching process. This press is especially suitable for the punching forming of high precision parts and special material. It is called the third generation new type forming equipment.

1.  High rigidity: steel plate welded frame is adopted. The high rigidity and precision structure features less deformation.

2.  High flexibility: With NC device controlling the running of servo motor and the movement of slide, the forming operation of different materials and different shapes can be easily completed by editing different control programs.

3.  High efficiency: The speed and stroke of slide can be set according to the requirements of forming process. Setting most suitable speed and stroke of slide for different workpieces to be processed can reduce efficiently the wasting of power for the idle stroke.

4.  High precision: The height for die assembly is fed back to the NC device through the linear grating ruler, which can significantly increase the precision of BDC adjustment, efficiently decrease the occurrence of non-acceptable products.

5.  Low noise, and die service life be lengthened. Under the circumstance of relative high production speed, the press can ensure the gentle contact of die and workpieces and low-speed forming, realize low noise and low vibration punching, improve the work conditions, and greatly lengthen the service life of dies.

6.  Energy saving and maintenance convenience: The servo motor only consumes energy in positive or negative rotation in punching process. It doesnt consume energy in idle rotation. Because of no need of flywheel, clutch and other parts, and that the drive system of slide is simplified, the consumption of lubricating oil decreases, which lowers the running and maintenance cost. So this press is an energy saving environment-friendly press.

7.  High safety: The NC device can comprehensively estimate the running condition of the system, and give quick response to the dangerous situations, which significantly reduces the safety accidents, ensures the safety of production.
