These two groups of frame-dependent classification can be further divided into presses with a single column, double column, and pillar-supported presses (Fig. However, in current machine building, heavy tie rods and other reinforcements are used to secure the machine’s sturdiness and accuracy. This advantage is perhaps outweighed by their faults, mostly attributable to the shape of their frame, whose construction is likely to suffer from deflection under load.
Their main advantage lies in the easily accessible work area, which accounts for shorter setup and adjustment times. Closed-frame presses or O-frame C-frame construction is often used with smaller-capacity presses.METALWORKING MACHINERY 5-1-3 Presses, According to Their Construction Variations due to the construction of presses allow for the distinction, based on types of press frames, as: Any use is subject to the Terms of Use as given at the website.
