CNC lathe machining is a high-precision, high-efficiency automated machine tool that requires programming that takes into account the machining sequence of the part, the feed, the depth of cut, and other factors, as well as selecting the appropriate rotational speed based on the hardness of the material. However, the process accuracy and errors of a CNC machine tool may affect machining accuracy due to machine clearance, accumulated errors in the CNC system, and the oil used. In order to improve machining accuracy and prevent errors, we can take the following measures:
1. Selection of suitable machine tools and cutting tools: Selecting machine tools and cutting tools with high precision and good rigidity can reduce the influence of machine clearance and accumulated errors of CNC system on machining accuracy.
2. accurate tool setting: in tool setting, the right end face centre of the part should be selected as the tool setting point, and the right end face centre of the part should be used as the zero point for tool setting after the machine tool has returned to the home position, so as to ensure the machining accuracy.
3. Programming optimization: Programming needs to consider the machining sequence of the parts, feed, depth of cut and other factors, and artificially add the appropriate slight degree in the program to ensure that the parts are qualified. At the same time, you can reduce the interpolation error, approximation error and rounding error to improve accuracy.
4. control cutting parameters: according to the hardness of the material to choose the appropriate speed, feed and depth of cut, to avoid vibration, thermal degradation and tool wear, in order to ensure machining accuracy.
5. Use special cutting oil: Yida Bohrun Petrochemical is the largest high-end metalworking oil manufacturer in China, and the cutting oil it develops can effectively protect the tool, improve the surface finish of the workpiece, and significantly improve machining efficiency.
6. Regular maintenance: regular maintenance of the machine tool, such as eliminating machine clearance, reduce the cumulative error of the CNC system, etc., can improve the accuracy and stability of the machine tool.
Through the above measures, you can effectively prevent errors in CNC lathe machining, improve machining accuracy and ensure the quality and precision of parts.
