CNC is the English abbreviation of computer numerical control program control machine tool. The numerical control system can process the control coding instruction program and decode it, so that the machine tool and cutting tool can work and process parts. CNC machine tools have great advantages over ordinary machine tools. The precision of CNC parts is high and stable. CNC machine tools can process high-precision parts that ordinary machine tools cannot complete.
For high-precision parts, machine tool factors and external factors will affect the machining accuracy. Machine tool factors include: tool processing path, tool quality, embryo quality, condensate performance, and external factors include: ambient temperature, chip emission, dust, and fire protection.
The cutting tools shall be selected reasonably, and the cutting tools for processing different materials shall be strictly used separately. The cutting tools of the machine tool shall be blown clean before processing, and the environment will have an impact on the accuracy of the workpiece. During clamping, check the tolerance with a calibrator and count with a caliper. Inject special condensate. Reasonably arrange the tool processing path. The program list of CNC processing documents should be standardized and easy to manage.
The machining speed of the machine tool should be strictly controlled, the spindle speed should be adjusted reasonably, and the feed speed in different areas should be adjusted. The machine can only be removed after the processing is completed and the quality is checked. Ensuring that the machine tool operates under the specified temperature and humidity can avoid the influence of external factors on the process accuracy to the greatest extent.
