Hardware processing, improve the quality of the workpiece,. First of all, it is necessary to 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 of improving precision machining.
1. Improve the cutting level
In precision hardware processing, when cutting workpieces. The workpiece surface will form an indentation almost the same as the tool shape, and leave a large amount of oxide scale, which will easily increase the roughness of the workpiece surface and reduce the surface quality of the workpiece. Generally speaking, in this case, the top arc radius of the tool should be appropriately increased during the cutting process. The feed of the tool should be appropriately reduced to reduce the height of the tool on the remaining area of the workpiece as much as possible, and to ensure that the surface roughness of the workpiece is controlled within an appropriate range. In this way, the edge accumulation and scaling on the surface of the workpiece can be effectively reduced, thereby improving the surface quality of the workpiece and prolonging the service life of the workpiece.
2. Increase the cutting speed
When cutting the workpiece, if the cutting speed is fast, the plastic deformation of the workpiece surface during cutting 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 process of processing. . The error of the tool and the fixture will also affect the accuracy of the workpiece, and corresponding measures can be taken to reduce the wear of the tool. This can improve the precision and quality of the machined workpiece.
The quality of medium-sized workpieces in precision hardware processing is the key to enterprise development. Therefore, for every precision machining factory, it is a top priority to improve the quality of precision machined workpieces and the quality of workpieces.
