CNC is the English abbreviation for computer numerical control program-controlled machine tools. The CNC system can process and decode the control coded instruction program to enable the machine tools and cutting tools to process parts. CNC processing machine tools have great advantages over ordinary machine tools. The parts processed by CNC have high precision and stability. CNC processing machine tools can process high-precision parts that ordinary processing 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, blank quality, condensation oil performance, and external factors include: ambient temperature, chip emissions, dust, and fire protection.
Reasonable selection of cutting tools, cutting tools for processing different materials must be strictly distinguished and used. Machine tool cutting tools must be blown clean before processing. The environment will have an impact on the accuracy of the workpiece. When clamping, use a calibration table to check the tolerance first, and use a caliper to count. Inject special condensate. Reasonably arrange the tool processing path. CNC machining file programs must be standardized and easy to manage.
The processing speed of machine tools must be strictly controlled, the spindle speed must be adjusted reasonably, and the feed speeds in different areas must be adjusted. The machine can be dismounted only 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 impact of external factors on process accuracy to the greatest extent.
