21 Foot 16 Gauge Automatic Folding Brake
The Roper Whitney AutoMax sheet metal brake is ideal for builders, metal part fabricators, roofing companies and others who create complex profiles and need the flexibility and throughput of a long folding system. It combines automated bending of angles up to 147 degrees, material clamping, and material support into a single CNC controlled system employing wing bending techniques.
Standard Features
- This machine features integrated sheet support and material positioning. Work pieces are fully supported by the back gauge tables beneath the clamping C frames, and automatically positioned to an accuracy of +/- .004″. The back gauge is positioned by a servo motor for low noise operation.
- Five conveniently spaced fingers provide positive contact with the sheet edge at all times and the fingers will travel down to 0.394″ position. The machine comes standard with a small parts back gauge finger set. The small parts back gauge allows the operator to run smaller parts than are normally able to be made on long folding machines. Parts down to 4 are possible. Maximum back gauge travel can be reached in less than 3 seconds. The standard back gauge depth is 49.
- Crowning is also standard. Each C frame has an adjustment dial that allows the operator to adjust the angle of bend at different points along the machine.
- The optional Slitter can be mounted to the lower frame of the machine, freeing the folding beam of any obstructions. The slitter is hydraulic powered via frequency invertor. The unit is guided by two precision ground linear rails. The rigid mount of the Slitting unit allows quick and accurate cutting of material at capacity.
