Dynamic pressure finishing system based on hierarchical structured composite elastic abrasive disk

Abstract

Disclosed is a dynamic pressure finishing system based on a hierarchical structured composite elastic abrasive disk, including a working table and an abrasive disk erected on the working table. The abrasive disk is connected with an abrasive disk driving device, which is composed of a motor and a reducer, and is used to control rotation of the abrasive disk provided with a bull ring and a polishing inner ring. A runner though which polishing fluid circulates is arranged on the surface of the abrasive disk, on which dynamic pressure adjusting devices presses a work piece. The system provided by the invention has the beneficial effects that: the system has a high degree of automation, can realize stepless pressure change by dynamically adjusting the pressure applied to the work piece with an electromagnetic device, and can adjust the applied pressure according to different processing stages of the work piece, improve work piece processing quality and reduce influence of human factors.

Description

technical field [0001] The invention relates to a dynamic pressure finishing system based on hierarchical and structured composite elastic grinding and polishing discs, which is suitable for grinding and polishing the surfaces of workpieces such as optical elements and amorphous film substrates. Background technique [0002] Finishing refers to the process of removing or removing a very thin material layer from the workpiece to be processed to improve the surface roughness of the workpiece or strengthen its surface. The methods used include polishing and grinding. The traditional finishing system using a grinding disc or a polishing disc separates the grinding and polishing processes, so that the system needs to replace the grinding disc with a polishing disc when transitioning from grinding to polishing, which makes it difficult to improve processing efficiency. Even if it is a single grinding process, a grinding disc with a single abrasive grain size cannot fully achieve t...
