Analysis of ways to improve the surface quality of large-scale CNC machining

How to improve the surface quality of large-scale CNC machining?

1. Choose faster CNC machine tool processing program flow: Improve the CNC machine tool processing program flow, provide faster CNC machine tool data information for processing, and ensure quality faster. Compared with general CNC machine tools, large-scale CNC machining not only requires the operator to have a high level of usage in the processing of parts, but also requires a high level of programming and technical analysis. To ensure machining precision, it is necessary to improve the refinement program flow in order to improve productivity.

2. Application of new high-efficiency cutting tools: The effectiveness and characteristics of large-scale CNC machining are closely related to the cutting tools. For the processing of parts with high precision standards, it is not only necessary to care about sound production processes, but also to select and apply new and efficient cutting tools. Nowadays, the reliability design of cutting tools can apply new core concepts of cutting tools, which can more effectively handle the safety factor, precision, surface roughness, rapid cutting, and enhance the strength of cutting paths in mechanical equipment processing.

3. Proper selection of cutting methods: In the case of using CNC machine tools for machining, there are two methods: forward milling and reverse milling. The actual effect of precision machining on the milling surface is better than that of reverse milling. Therefore, in the processing of parts, it is advisable to choose forward milling as much as possible to improve the surface quality of the parts when the standards are feasible. In the turning process of shaft parts, it is also necessary to choose the same lathe tool as much as possible for the processing of different motor shafts, in order to reduce the marks caused by the tool connection faster.

4. Effective design scheme for entering the cutting line: In the case of using large-scale CNC machining to carry out part processing, a scheme should be designed for entering the cutting line to enhance the cutting perspective of the CNC lathe. In order to better achieve the actual effect of reducing cutting tool marks and ensure that the appearance quality is not compromised, it is necessary to carry out overall planning for tool entry. The key to the breakthrough of the tool is to gradually increase the extensionality near the part, so as to ensure the smooth surface of the contour. When entering the tool, it is necessary to choose a smaller milling rate as much as possible to maintain a slow cutting rate, making the cutting smooth and smooth, and thus ensuring cutting quality.
