Description

technical field [0001] The invention belongs to the technical field of plane grinding, and more specifically relates to a novel high-precision shape-controlling plane grinding driving device. Background technique [0002] Plane grinding must ensure flatness, surface roughness, surface and subsurface dislocation configurations and residual stress, etc. High-precision plane grinding is the necessary basis for ultra-smooth polishing. Defects such as uniformity and edge collapse are closely related to the surface state of the previous grinding process. An important means to solve these problems is to continuously improve the surface shape accuracy of the workpiece after grinding until it meets the technical requirements before polishing. Therefore, how to realize high-efficiency, high-precision shape-controlled plane grinding is the main technical difficulty at present. [0003] The type of grinding track depends on the driving mechanism. At present, the driving methods of pla...

[0005] In order to overcome the defects existing in the prior art, the present invention provides a new type of high-precision shape-controlled plane grinding drive device, which overcomes the deficiency of optimizing the uniformity of the grinding trajectory by relying solely on the rotation speed ratio and the adjustment of process parameters. By adjusting the speed ratio to an irrational value within a certain speed range, and according to the size of the workpiece to be processed, the function of adjusting the speed ratio of different irrational numbers can be realized, which can significantly improve the grinding efficiency and the surface quality of the workpiece.
