The control system of the CNC machining center generally controls the machine tool to automatically start and stop, reverse and change the speed of the spindle according to the digital program instructions. The tool amount and travel path can complete various auxiliary actions required in processing.
CNC machining is programmed and controlled according to the programmed program, usually G code, to make the machine tool process. G-code digital language can control the machining process of CNC machine tools. The tool control system uses different position coordinates to control the tool feed, spindle speed, coolant and other functions.
The movement of the main shaft of the horizontal lathe is transmitted to the tool rest through the hanging wheel frame, the feed box and the slide box, and the longitudinal and transverse feed movements are ended. The CNC lathe uses a servo motor, which is transmitted to the slide plate and the tool holder through the ball screw, and ends the z-direction (longitudinal) and set-direction (transverse) feed motion. Precision CNC machining also has the function of various threads, and the movement connection between the rotation of the spindle and the movement of the tool holder is controlled by the CNC system. Use the dry running energy of the CNC machine tool to analyze the correctness of the tool path. When the digital program is entered into the machine tool, the fixture tool and the workpiece are installed. Press the dry run button, the spindle does not rotate, and the worktable automatically runs along the program track. At this step, find out if the tool is in contact with the workpiece or fixture. The above operation control is controlled by the cam, die and block device in the form of analog quantity. The machining accuracy of the parts is affected by the accuracy of the cam and the mold. It can process complex parts with certain flexibility and versatility, and the process preparation time is very long. CNC machining solves the processing problems of complex and precise, small batch and multi-variety. It has been widely used in modern industry, greatly improving the production efficiency of enterprises.
The above is the working principle of CNC machining. We are a custom factory.
