Ideal CNC Angle Line Machine for for punching, marking and cutting of angle bars for structural steel, power transmission tower and telecommunication tower. It includes 8 parts: Transverse conveyor, turnover conveyor, infeeding conveyor, main machine body, finished angle bar outfeeding conveyor, hydraulic station, electrical control system and operation panel. CNC Angle Line Machine's Technique Characteristics: 1) Good rigidity, compact structure, optimized arrangement of work pieces, good function of cutting integrated, high material using rate. 2) Marking, punching, cutting, are automatically operated with high efficiency. 3) Computer has friendly interface, which can show work piece's figure, easy for operation. 4) Easy programming, only need to input the data of work piece size, hole diameter, back mark value and quantity wanted for finished pieces. Or the programming data created from sample yardage software can also be directly used 5) Many solutions are adopted to resolve problems of difficult infeeding angle bar and back mark error which are caused by angle bar deformation. 6) With PLC and servo motor the machine can get high efficiency and stable work accuracy. 7) The control system has self-diagnose and data statistics 8) The key hydraulic, pneumatic and electrical components are all imported.
