How to improve the quality of precision machined workpiece

Classification:Common Problem Release time:2021-09-09 12

In order to improve the workpiece quality in precision machining, first of all, we should understand the error of precision machining and the main factors that are easy to cause workpiece deformation in precision machining. At the same time, we should also understand the three principles to improve the precision of precision machining.

1. Improve cutting level

In precision machining, when the workpiece is cutting, the surface of the workpiece will form almost the same impression as the tool shape and leave a large number of scales and thorns, which is easy to increase the roughness of the workpiece surface and reduce the quality of the workpiece surface. In this case, during cutting, the arc radius of the tool shall be appropriately increased, the feed amount of the tool shall be appropriately reduced, and the height of the residual area of the tool on the workpiece shall be reduced as much as possible, so as to ensure that the roughness of the workpiece surface is controlled within an appropriate range, which can effectively reduce the chip and scale on the workpiece surface, so as to improve the quality of the workpiece surface, Prolong the service life of the workpiece.

2. Improve cutting speed

When the workpiece is cut, if the cutting speed is high, the plastic deformation of the workpiece surface can be greatly reduced. The higher the cutting speed is, the smaller the degree of plastic deformation is, which can effectively reduce the roughness of the workpiece surface. If the cutting speed is not enough, the workpiece will produce chip nodules in the cutting process and 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 itself will directly affect the accuracy of the workpiece. It is necessary to ensure the high accuracy of the machine tool itself in order to effectively reduce the error in the machining process. The error between tool and fixture will also affect the accuracy of machining workpiece. Corresponding measures can be taken to reduce tool wear. This can improve the accuracy of the workpiece and improve the quality of the workpiece.

Workpiece quality is the key to the development of enterprises. Therefore, it is urgent for every precision machining plant to improve the quality of precision machined workpieces and improve the quality of workpieces.
