Abstract

The invention discloses an ultraviolet light response self-assembly collaborative dielectrophoresis polishing method and device. The method comprises the following steps that a tool can achieve translation of X, Y and Z axes through a three-degree-of-freedom moving guide rail platform, and a motor drives a spray head to swing in two directions; two-stage viscosity conversion is carried out on the polishing solution through the adjustable light control device, so that the initial viscosity of the polishing solution and the holding force of the ultraviolet self-assembly group on polishing abrasive particles can be regulated and controlled in a large range, and the proper jet flow viscosity and the large abrasive particle holding force are obtained. The initial viscosity of the polishing body is changed through the light with different wavelengths emitted by the light source, the material removal rate of workpiece polishing can be effectively increased, the surface quality is improved, the high-quality surface precision is guaranteed, the surface roughness is reduced, and deterministic controllable polishing of a complex curved surface is achieved.

Description

technical field [0001] The present invention relates to the field of ultra-precision machining, and more specifically, to an ultraviolet light-responsive self-assembly cooperative dielectrophoretic polishing method and device. Background technique [0002] Since the Industrial Revolution, the manufacturing industry has always been dominated by mechanical technology. With the continuous development of science and technology, many engineering materials are more advanced than before, and the precision requirements for processing technology are also higher. Therefore, polishing technology has become a crucial technology in precision machining. Polishing is a processing method that reduces the surface roughness of the workpiece by using mechanical, chemical or electrochemical effects to obtain a bright and flat surface. At this stage, the polishing method for flat workpieces is relatively mature, using polishing wheels, but the development of technology for complex curved surface...
