Hydraulic C Type Punching Machine

Punch presses are large machines with either a 'C' type frame, or a 'portal' (bridge) type frame. The C type has the hydraulic ram at the top foremost part, whereas the portal frame is much akin to a complete circle with the ram being centered within the frame to stop frame deflection or distortion. C-frame presses are a commonly used type of hydraulic press. These presses get their name from the fact that the press itself is shaped like the letter “C”, however the press may be referred to by other names such as “gap-frame press”.
