The surface polishing machine mirror processing technology is an emerging comprehensive processing technology, which integrates advanced technological achievements such as modern machinery, optics, electronic computers, measurement and materials, and has become an important symbol of the state of science and technology development.
With the continuous development of various new functional ceramic materials and the widespread application of these materials in various high-performance electronic components, optics, and information systems, the processing accuracy of components and parts is getting higher and higher, and some even It is required to achieve nanometer or higher processing accuracy and non-destructive surface processing quality. For polishing, it is mainly to remove the fine protrusions and surface damage layers on the surface of the workpiece under the premise of maintaining the good flatness obtained by grinding to obtain the specular gloss. Therefore, it is required to polish the entire workpiece surface uniformly and non-directionally.
Reflected in the speed, the relative speed of each point on the workpiece surface should be kept constant at all times. The workpiece is a rigid body that does not deform, and the polishing disc is an elastic body that can deform according to the shape of the workpiece's working surface. At this time, the thickness and shape of the abrasive particles and the processing fluid between the two can be ignored. It is considered that the workpiece is fully in close contact with the polishing disc; when the size of the workpiece is larger than the radius of the polishing disc or the eccentricity is too large, the workpiece will be exposed For a polishing disc, a part of the surface cannot always be in contact with the polishing disc; when the parallelism error of the workpiece material exceeds the allowable range during the grinding or polishing process, its parallelism needs to be corrected.
In the mirror polishing process of the plane polishing machine, it can be considered that the removal amount of the workpiece is mainly determined by the length of the grinding path, so directly controlling the length of the grinding path length on the surface of the workpiece can more accurately control the removal amount of the workpiece.
