ECCENTRIC PRESSES
6K Series

mammut eccentric press

C-frame presses derive their name from the C-shaped throat opening. In addition to the familiar open back design, this style of machine has a long history of use for portable hole punching. The press-brake is also a type of gap-frame press.

Presses with force capacities up to 250 tons and larger, gap frame presses are less costly than a straightside press having the same force capacity. In the 35 to 60-ton force range, they cost approximately half that of straightside presses.

The chief limiting factor of this type of machine is that it has more deflection than a straight-side press for a given load. The deflection has both a vertical and angular component.

Gap or C-frame presses have many useful features. These include excellent accessibility from the front and sides for die setting and operation. The machines also cost substantially less than straight-side presses. The open back is available for feeding stock as well as ejection of parts and scrap.
A further advantage of a gap frame press is that the machine is easier to set-up than a straightside press. The diesetter has much greater freedom of access to locate and bolt the die in place. The open back is also accessible for discharging finished parts and scrap as well as feeding stock. Gap-frame presses generally have less height than a straightside press of comparable tonnage. This is a valuable consideration when overhead clearance is limited.
