In order to improve the quality of the workpiece in precision hardware processing, we must first understand: the error of precision machining and the main factors that easily cause workpiece deformation in precision machining. At the same time, we must also understand the three principles to improve the precision of precision machining.
1. Improve the cutting level
In precision machining, when cutting the workpiece, the workpiece surface will form an indentation that is almost the same as the shape of the tool, and leave a lot of scales, which can easily increase the roughness of the workpiece surface and reduce the surface quality of the workpiece; In this case, the top arc radius of the tool should be appropriately increased during the cutting process, and the feed rate of the tool should be appropriately reduced to reduce the height of the remaining area of the tool on the workpiece as much as possible to ensure the surface roughness of the workpiece. Controlled in an appropriate range, it can effectively reduce the accumulation edge and fouling on the surface of the workpiece, thereby improving the quality of the workpiece surface and prolonging the service life of the workpiece.
2. Increase the cutting speed
When cutting a workpiece, if the cutting speed is high, the plastic deformation of the workpiece surface during the cutting process can be greatly reduced. The higher the cutting speed, the smaller the degree of plastic deformation, which can effectively reduce the surface roughness of the workpiece. If the cutting speed is not fast enough, the workpiece will accumulate edges during the cutting process, which will affect the surface quality of the workpiece.
3. Improve the precision of precision machining equipment
The precision machining of the workpiece is mainly completed by the machine tool. The error of the machine tool will directly affect the accuracy of the workpiece. This requires the machine tool itself to have high precision, so as to effectively reduce the errors in the machining process. Errors of tools and fixtures also affect the accuracy of the workpiece, and corresponding measures can be taken to reduce tool wear. This can improve the accuracy and quality of the machined workpiece.
The quality of workpieces in precision hardware processing is the key to enterprise development. Therefore, for every precision machining factory, improving the quality of precision machining workpieces and improving the quality of the workpieces are the top priorities.
