What misconceptions may arise during CNC machining of lathes

Lathe CNC machining is a high-precision machining process, but in practical operation, the following misconceptions may occur:

1. tool wear: during lathe processing, the selection and wear of tools directly affect the processing quality. If the tool wear is large, the accuracy will be affected. Tools should be replaced or trimmed regularly to avoid excessive wear or errors caused by tool interruptions during processing.

2. Excessive cutting: If excessive cutting occurs, it may lead to an increase in material surface roughness, excessive thermal deformation, loss of balance, excessive bearing and motor pressure, and other issues, leading to a decrease in machining quality. In processing settings, attention should be paid to selecting appropriate cutting tool materials and cutting depths.

3. Inaccurate positioning: CNC machine tools rely on coordinate determination to execute movements, and their numerical accuracy is higher than that of ordinary machine tools. Therefore, incorrect numerical settings or values that are too small can easily lead to machining errors. Reasonable positioning and selection of appropriate machining coordinate system should be carried out strictly according to the machining program.

4. Poor quality of machine tools: If the quality of the machine tool is not ideal, it can also lead to machining errors. The precision, rigidity, and power requirements of CNC machine tools are high, and it is necessary to maintain the stability and accuracy of the machine tool.

5. Unstandardized operation: CNC lathes need to be carefully operated during operation. If the operation is not standardized, it can lead to machining deviation. For example, actions such as crashing parts, releasing chucks, machine tool self stopping or manual stopping during work can all cause errors. Teachers should strengthen the training and education of operational skills to improve the skills of operators.
