Machine Description:
This machine is mainly used for drilling connecting plates of buildings, bridges, steel towers and other steel structures. The machine can clamp 4 work-pieces at the same time, with fast hydraulic grippers all around. Chip removal automatically, cooling liquid recycling used. Drilling head has stroke self-controlled function, it can automatically convert from fast feeding to normal feeding without setting the thickness of work-piece and the length of the drilling head. Electrical control adopts upper computer plus PLC control, direct conversion of CAD/CAM.
