JH21 High Accuracy Open Die Forging Press Machine For Blanking Cold
Stamping Process
Description:
1. JH-21 Series Presses is one of the new generation of plate
press,The machine is for cutting, punching, blanking, bending and
light stretching work.
2. C-Type Steel-welded frame, high rigidity and less deformation
Compact,wide body frame eliminating vibration for improved ide life
and machine.
3. Rigid construction guarantees exact die mating,Six-side long
rectangle guides of the slide with high moving precision and high
accuracy, extending the service life of the die.
4. Highly advanced, rigidly supported gears, operate in oil bath
without any noise saves space, reduces, shaft deflection, increases
gear life.
5. High accuracy, high efficiency, simple and convenient operation,
good performance, favorable price and best service
