BOSCHERT COMPACT 750 ROTATION punching machine

BOSCHERT COMPACT 750 ROTATION punching machine was built in Germany in 2015. A machine with compact dimensions and design is used for precise nibbling, punching and stamping of sheet metal up to 6 mm thick with a force of 28 tonnes. High stability and rigidity are maintained even during demanding series machining.

The BOSCHERT COMPACT 750 X 2000 CNC punching machine is controlled by a modern LABOD CNC control, which allows machining of workpieces with larger dimensions than the basic working range of the X and Y axes in the most optimal way. The possibility of rotating the sheet in relation to the Y axis is determined by a special function used in the control, which then performs automatic repositioning of the workpiece along the X axis. To guarantee high accuracy during repositioning, the sheet is immobilised on the machine table by two hold-downs that prevent the workpiece from moving.

Fast and trouble-free punching of even the most complex shapes is ensured by the single-station rotary head with drive of the ROTATION tooling station, which allows smooth 360° rotation of any tool. The machine also allows automatic creation of machining programmes and simulation of the punching process with selection of appropriate tools, performed by external CNC/KAD METALIX software with the possibility of importing files from other CAD/CAM programmes.

Among the extensive equipment of the BOSCHERT COMPACT ROTATION INDEX hydraulic punching machine are e.g. the TRUMPF quick tool-change system with the possibility of justifying individual tools in any position, a brush table and the BOSCHERT REVOTOOL system with punch and die holder. The total weight of the machine is 7500 kg.
