Polishing system based on non-Newtonian fluid and polishing method of polishing system

Abstract

The invention discloses a polishing system based on non-Newtonian fluid and a polishing method of the polishing system. The polishing system comprises a polishing tool device, a non-Newtonian fluid auxiliary device and a control device, wherein the polishing tool device is used for driving a work piece to move inside a polishing container in which the non-Newtonian fluid is contained, and the non-Newtonian fluid contains an abrasive material; the non-Newtonian fluid auxiliary device can be used for changing the viscosity of the non-Newtonian fluid by utilizing changes of pressure, speed, vibration or ultrasonic frequency so that the work piece can be polished by utilizing the abrasive material; the control device is used for controlling the polishing tool device to make the work piece move inside the polishing container. Therefore, the polishing system disclosed by the invention can be used for polishing a work piece having a three-dimensional shape.

Description

technical field [0001] The invention relates to a polishing system and a polishing method, in particular to a non-Newtonian fluid-based polishing system and a polishing method. Background technique [0002] With the development of industry and technology, the shapes of products required for surface finishing are different, and the requirements for surface quality are continuously improved. At the same time, higher requirements are put forward for processing efficiency, cost control, and waste liquid treatment; especially in the fast replacement In the field of consumer goods, it is not only necessary to achieve a high surface effect, but also to reduce costs and improve efficiency, so as to shorten the production cycle and achieve higher economic benefits.

Problems solved by technology

[0003] Although the known mechanochemical polishing has high processing efficiency, it belongs to contact polishing, which cannot process workpieces with three-dimensional (3D) shapes, and requires the cooperation of grinding tools (such as polishing leather), which not only increases the cost, but also affects factors More and more difficult to control; more importantly, the treatment of a large amount of waste liquid has always been a big problem

[0004] Known non-contact polishing such as jet polishing and magnetorheological polishing can achieve a fairly high surface quality, and can theoretically process any shape. However, in practice, it has the disadvantages of low processing efficiency and high cost, but it can process The material is also limited. Taking magnetorheological polishing as an example, the cost of magnetorheological fluid is very high, and currently it is mainly used for optical processing of optical mirrors.
