Hydraulic Presses are designed for moderately heavy and comparatively short bending requirements. Other designs have two bending length capacities - overall and between housings. However, on the AT 1020 100 the two are the same, so bending length is not limited to the pass-through distance between housings and there is no need to pay the extra cost for a longer machine.
A single hydraulic cylinder supplies power to the ram so ram parallelity during descent and return is assured and complex components are eliminated. Two auxiliary cylinders are used for guiding the ram. Gibs and other costly and maintenance-intensive guiding systems aren't necessary with this system.
The frames are constructed of structural steel and plate weldments providing a dynamically solid and highly stable unit. The standard beds are larger front-to-back than on other machines, allowing for the use of conventional press brake dies and other tooling.
The AT machine design provides a very large shut height to accommodate both normal and unusual requirements. The bed can be easily and quickly positioned for the required die space. Stroke length is adjustable from minimal to the maximum indicated for each machine. All models are equipped with three ram speeds for the most efficient operation: Approach, Bend, Return, and they are available in standard speed and optionally with high-speed.
AT Models are equipped with a T-slot upper platen to hold bending, punching, straightening and similar tooling as well as optional press brake dies. T-slots are arranged across the narrow dimension of the bed or optionally in other patterns.
All models are equipped with stepless pressure and stroke adjustments. Internationally recognized sources are used for electrical and hydraulic components. Power is supplied by an amply sized central hydraulic system with controls. Operation is by a two-hand control mounted on a console with a trailing lead. Check valves protect the hydraulic system against overload. An emergency stop control is standard.
