How to improve the surface quality of CNC machining parts?
CNC machining can solve some of the processing problems of large and small batch parts in industrial production needs.The machining of some precision parts can also be done through the CNC machining center,but this improves the surface quality of the parts.How can the surface quality of the CNC parts be improved during the actual operation?
1.Reasonable design cut-in and cut-out route
When using the CNC machining center for part machining,the cutting and cutting route should be designed to optimize the cutting angle of the machine.In order to reduce the effect of the cutter marks and ensure that the quality of the surface is not affected,it is necessary to plan the cutting of the cutter.The cutting point of the tool is mainly from the peripheral extension of the part to ensure a smooth contoured surface.Cutting the tool should try to select a smaller feed rate,so that it can be cut at a slow speed,so that the cutting is smooth and smooth,thus ensuring the cutting quality.
2,the correct choice of cutting processing
When machining with a CNC milling machine,there are two methods:down milling and up milling.The finishing effect of the down milling is better than the up milling.Therefore,in the processing of parts,if possible,select the down-cutting to improve the surface quality of the parts.In the turning of shaft parts,it is also necessary to select the same turning tool for the processing of different journals,so that the traces caused by the joining can be better reduced.
3,the use of new efficient tools
The efficiency and performance of CNC machining centers are inseparable from the tools.For parts with high precision requirements,not only the perfect process,but also the selection and use of new high-efficiency tools.Today's tool optimization design can use new tool concepts to more accurately address machining safety,accuracy,surface roughness,high-speed cutting,and the ability to optimize cutting paths.
4,using the best CNC machining program
Optimize the NC machining program to provide the best CNC data for machining,which can improve the quality.Compared with ordinary machine tools,CNC machining centers not only require operators to have a high level of operation,but also have a high level of programming and process analysis.To ensure machining accuracy,you need to optimize the refining process to increase productivity.
In the actual production process,the relevant process flow is strengthened,the relevant process means are used to perfect the processing details,and the surface roughness of the parts is ensured to prevent the surface performance from being affected by the surface roughness.This can improve the surface quality of the workpiece.
