J25 Series C-Frame Double Crank Press

This C-frame double crank press is applicable for stamping and shallow drawing of large sized sheet metals. It is outfitted with progressive dies or other types of multi-station stamping dies for processing parts and components of complex structures.

Product Features
1. The steel welded frame delivers high rigidity and less chance for deformation. Also, the C-frame press is fixed with wet type clutch which delivers low noise and convenient maintenance.
2. The C-frame double crank press comes with a six-surface slide guide which offers very long guide way. This ensures stable and precision movement of the slide.
3. The number of strokes is adjustable infinitely. Thus, this metal forming press is able to satisfy the processing demand for a great variety of workpieces.
4. Submerged lubrication for transmission gear features low noise and stable transmission.
5. Due to the hydraulic overload protection system, this range of sheet metal forming press offers emergency stop once there is overload, thus protecting the press dies and preventing damages to the machine.
6. The electrical system for the double crank press is controlled by a PLC and an encoder. The human machine interface ensures convenient operation and reliable performance as well.
7. Optional configurations such as the air cushion, photoelectric protector, transmission output shaft, automatic feeding unit, and more are available.
