ZK5550(B) control plane drilling machine is a special machine tool for connecting plate processing. This equipment is multi-station processing form, can be single, multi-piece processing, also suitable for multi-piece overlapping processing, effectively improve the work efficiency. The axial feed of the main shaft of the equipment is realized by servo motor drive, synchronous belt and pulley deceleration, ball screw pair drive and linear guide rail support, the feed speed and stroke can realize digital control; This equipment combines numerical control system, digital AC servo system and precision machinery together to form high-tech products with high reliability, high precision, easy operation, strong process applicability and high production efficiency. The operator only needs to input the relevant size of the workpiece, the input can be repeatedly called, without the preparation of complex processing program, is an ideal automatic, efficient metal drilling machine tool.
