C-frame presses, also commonly referred to as gap frame presses, are characterized by their unique frame style, resulting in the formation of a “C” around the bolster plate. Beckwood offers C-frame presses in a variety of bed sizes and tonnages.
Inherent to a typical C-frame design is a tendency for the machine to “yawn” or deflect as tonnages and bed sizes increase. Beckwood’s rigidly guided C-frame designs are engineered to resist deflection or “yawning” using gib-guided ram bolsters or precision graphite impregnated bronze bushings.
While three-sided access to the forming area is appealing (or required) for many applications, C-frame presses are typically best suited for applications needing smaller bed sizes and lower tonnages, like assembly.
Advantages of C-Frame Presses
- Three access points to the working area facilitate part loading and unloading as well as easy die maintenance and adjustments
- More economical than a straight-side press
- Machines with higher tonnages or larger bed sizes can use additional materials to reinforce the frame, counteracting deflection or “yawning”
