CNC grinding machines have many advantages in daily applications. As long as it is set up properly, there will be no errors or improper human operations. Meanwhile, with the passage of time, CNC machine tools may be damaged due to prolonged operation, and more difficult part designs can also be carried out to meet the growing demand for difficult to machine parts in the modern market. Now let's talk about how to avoid errors in the transformation of CNC grinding machines. Firstly, we need to analyze why there are obvious errors after the transformation? It is formed under the influence of different factors, which not only depends on the orientation accuracy of the tool and other workpieces, but also on the errors in the planning process of the grinder, the calibration errors of the grinder parts, and the errors of the grinder equipment. The grinder itself generates high temperature heat during operation. Not only the internal heat source of the machine, but also the heat source in the external environment can cause thermal deformation errors. Secondly, during the processing, errors can also occur under the influence of external airflow, oscillation, and humidity. Generally speaking, vibration is caused by the self weight deformation and cutting force of the grinder. In addition, the wear of the spindle, cutting tools, and workpiece fixtures can also lead to errors in machining accuracy. In summary, the errors of CNC grinders in machining can be divided into the following categories: part size errors, thermal deformation errors, equipment errors, oscillation errors, servo tracking errors, interpolation errors, and detection errors. Controlling from the above aspects can avoid excessive errors in CNC transformation and affect the quality of finished products. For CNC grinding machines, people are facing more and more problems in industrial production and creation. Meanwhile, with the continuous advancement of technology, mechanized production is becoming increasingly powerful. For people, how to solve problems with less manpower and material resources has become a reasonable path pursuit in our industrial production, encouraging workers to use more advanced maintenance techniques to repair CNC machine tools. Avoid excessive errors in CNC conversion that may affect the quality of the finished product
