How to improve CNC machining quality

With the improvement of living standards, the quality of life has been greatly improved. Many people are thinking about how to improve the quality of life. The better the technology is, the more market demand will be, and the higher the efficiency will be. So how to improve the quality of CNC machining parts? Let’s learn about it together

1. Before CNC machining, use the calibration table to check whether the tool swing is within the allowable tolerance range. The tool head and lock nozzle should be blown clean with air gun or cleaned with cloth before machining. Foreign matters have a certain impact on the accuracy and quality of the workpiece.
2. The use of special cutting oil products can effectively avoid the problem of poor precision due to the performance of rapeseed oil, mechanical oil and other non-specific oil products. At the same time, the special cutting oil has good anti-oxidation and corrosion ability, which can effectively prevent the yellow robe rust problem.
3. CNC machining program sheet should be consistent with the reference angle direction marked on the mold, and then check whether it is aligned with the upper 3D drawing, especially for the workpiece with water transportation, it is necessary to see whether the 3D drawing is consistent with the water transportation of the workpiece. If there is any ambiguity, it is necessary to timely feed back to the programmer or find the fitter to check the 2D drawing to see whether the 2D and 3D datum angles are consistent.
4. Before processing, it is necessary to understand the contents of CNC processing program sheet. There must be 2D or 3D drawings on the program list, and the hexagonal data of “x length, y width and Z height” shall be marked. If there is a plane, it shall be marked with “Z” value. After processing, the operator can easily check whether the data is correct, and the tolerance data shall be indicated if there is tolerance.
5. Ensure that the equipment operates under the temperature and humidity within the specified working range to avoid the influence of external factors on the process accuracy to the greatest extent.
