Do you know what is CNC machining




Numerical control machining refers to a process method for processing parts on a CNC machining. The process regulations of CNC machine tool processing and traditional machine tool processing are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated processing.

Numerical control processing refers to the processing in which the control system issues instructions to make the tool perform various movements that meet the requirements, and expresses the shape and size of the workpiece in the form of numbers and letters, as well as the processing requirements of the processing technology. It generally refers to the process of processing parts on CNC machine tools.

A CNC machine tool is a machine tool controlled by a computer. The computer used to control the machine tool, whether it is a special computer or a general-purpose computer, is collectively called a CNC system. The movement and auxiliary actions of the CNC machine tool are controlled by the instructions issued by the CNC system. The instructions of the numerical control system are compiled by the programmer according to the material of the workpiece, processing requirements, characteristics of the machine tool and the instruction format specified by the system. The numerical control system sends out operation or termination information to the servo device and other functional components according to the program instructions to control various movements of the machine tool. When the part processing program ends, the machine tool will automatically stop.

For any kind of CNC machine tool, if there is no program command input in its CNC system, the CNC machine tool cannot work. The controlled actions of the machine tool roughly include the start and stop of the machine tool; the start and stop of the spindle, the conversion of the rotation direction and the speed; the direction, speed, and mode of the feed movement; the selection of the tool, the compensation of the length and the radius; the replacement of the tool, and the cooling The opening and closing of the liquid.
