Problems solved by technology

In this way, the processing efficiency will be low and the processing effect will not be obvious.
At the same time, there will be serious surface scratches, surface molding marks that cannot be eliminated, and other processing problems that affect the mirror effect.
[0006] When conventional fixed abrasives are used for mirror polishing of zirconia and alumina ceramics, high-speed grinding cannot be performed, resulting in low processing efficiency
Poor thermal conductivity also...

Abstract

The invention relates to a formulation of a zirconium oxide and aluminum oxide ceramic mirror polishing pellet tablet fixation grinding material. A conventional fixation grinding material can not undergo high-speed grinding when being used for zirconium oxide and aluminum oxide ceramic mirror polishing, and therefore machining efficiency is low. The formulation is characterized by comprising the following components of copper powder, diamond powder, resin powder, silicon carbide powder and graphite powder, namely by weight ratio, 50.0-52.0 parts of the copper powder, 10.0-11.5 parts of the diamond powder, 9.5-12.0 parts of the resin powder, 2.0 parts of the silicon carbide powder and 2.0 parts of the graphite powder. According to the formulation, wear resistance is fully considered, surface shape adjustment is small, thermal conductivity is good, water cooling can be easily conducted, and efficiency of mirror polishing is greatly improved. By adopting produced fixation grinding material pellet tablet to machine zirconium oxide products and aluminum oxide products, machining surface quality can be greatly improved, and the surfaces of the products reach 18 nanometers (Ra).

Description

technical field [0001] The invention relates to the field of precision grinding of zirconia and alumina ceramics, in particular to a zirconia, [0002] Formulation of fixed abrasive for alumina ceramic mirror polishing pellets. Background technique [0003] Fixed abrasive high-speed grinding was developed abroad in the 1960s, and my country began to develop it in the 1970s. Fixed abrasive grinding has better solved most of the deficiencies in the traditional slow grinding of loose abrasives. Its biggest feature is that it can significantly improve the grinding efficiency, but the low processing efficiency is the biggest obstacle that restricts the wide application of traditional grinding. Therefore, high-speed grinding with fixed abrasives has attracted people's attention since the emergence of high-speed grinding with fixed abrasives. [0004] In order to better improve the grinding effect of fixed abrasives and improve the quality of pellets, Ju'ichi Ikeno and others fro...
