Sterling STC420 AX CNC Twin Column Automatic Band Saw

The ultimate in sawing productivity. With servo controlled cutting and feeding operations the Sterling AX models offer extremely precise control over cutting parameters. The CNC control stores cutting programs as well as controlling feature such as blade deflection allowance and variable blade tension according to the cutting cycle. With a rigid twin column design the saw frame runs on linear guides and descent is controlled by a servo motor. The feeding operation is also servo controlled providing exceptional repeatability of cut lengths with a shuttle function for longer lengths if required. These models are ideal for production cutting of solid materials but are also available with options such as specific vices for bundle cutting tubes and bars. A chip conveyor is fitted to ensure the continuous removal of swarf from the cutting area.
