Jh25 CNC Punching, Marking and Cutting Angle Line Machine
The JH25 C-frame double crank press is the commonly used product in blanking, piercing and cutting the larger piece of sheet metal.
The worktable in large size is more suitable for the progressive dies working on different stations, which can greatly improve the production efficiency.

FEATURES:
1. Welded body with steel plate and high intensity;
2.Suitable for multiple dies automatic line and multi level dies continuous punching;
3.Double crankshaft pitmen totally eliminating side forces by reverse rotation;
4.Combined wet multi discs friction clutch and brake;
5.Cluster gear adopts the flooding oil lubrication;
6.Six-face rectangle lengthen guide;
7.Adopts electric die height adjustment with digital display;
8.Equipped with hydraulic overload protecting device.
