Automatic 75CNC Tube Benders
Bossray 75CNC Tube Benders is the advanced Tube Benders with multi-axis servo motor controlling and multi-layers mould function. The machine applys professional skills of industrial computer and CNC Pipe Benders into multi-axis servo motor and hydraulic servo driving. It can work automatically like feeding,rotating,changing moulds, reading drawings, editing and revising technical documents and correcting datas. What's more, working with robots, it also can loading and unloading automatically, testing pipes and revise technical datas and production procedures according to the test result. It can diagnose fault automatically, 3D pipe display and simulation,3D interference detection etc. It is the first choice for the field of aerospace,nuclear power, automobile, motorcycle, shipbuilding, petrochemical,electricity, gas, boilers, fitness and sports equipment to bending pipes. 
1-9 stacks tooling are optional.
