In the steel structure of a large number of plates which need to be drilled, connecting plate hole machining accuracy directly affects the quality of component assembly. In order to meet the processing requirements of the plate, but if by marking, punching, drilling with common to ensure quality of workpiece, is time-consuming and expensive work, its quality is not high, the user must be equipped with one or more machines. The CNC surface drilling equipment is single, multi form, multi processing, is also suitable for multiple overlapping processing, which can be customized according to user needs the work table and the working height, in order to improve the work efficiency can be equipped with multi spindle while drilling. This machine is the numerical control system, digital AC servo system, photoelectric encoder, the magnetic grid ruler and precision machinery together, which has high reliability, high precision, convenient operation, strong adaptability, high production efficiency, high cost of high-tech products. The operator as long as the workpiece dimensions can be input, the input can be called once, without processing step in preparation of the complex, is an ideal automatic, efficient metal cutting machine tool.
