Method of fabricating abrasive having sliding and grinding effects

Abstract

An abrasive is fabricated to obtain sliding and grinding effects. In the abrasive, grinding particles are wrapped by a wrapping material. Various sizes and shapes of molds and micro components can be finely polished to obtain mirror-grade surfaces.

1 . A method of fabricating an abrasive having sliding and grinding effects, comprising steps of:
 (a) melting a wrapping material under a temperature to be uniformly mixed with grinding particles by stirring in a compound abrasive mixing bucket at a volume ratio of said grinding particles to said wrapping material;   (b) spraying said mixture of said grinding particles and said wrapping material into a compound abrasive collecting chamber from a micro-pore by using a high-pressure gas to obtain micro-balls each comprising said grinding particles and said wrapping material; and   (c) inputting a low-temperature gas into said compound abrasive collecting chamber to instantly solidify said micro-balls to obtain a compound abrasive.   
     
     
         2 . The method according to  claim 1 ,
 wherein said wrapping material is selected from a group consisting of a wax, an animal oil, a plant oil and a hot plastic resin.   
     
     
         3 . The method according to  claim 1 ,
 wherein said grinding particle is selected from a group consisting of an oxide, a polymer and an element.   
     
     
         4 . The method according to  claim 3 ,
 wherein said grinding particle is further selected from a group consisting of a diamond, SiC, polycrystalline cubic boron nitride (PCBN) and aluminum oxide (Al 2 O 3 ).   
     
     
         5 . The method according to  claim 1 ,
 wherein said grinding particle has a diameter between 1 and 100 micro-meter (μm).   
     
     
         6 . The method according to  claim 1 ,
 wherein said high-pressure gas has a pressure between 1 and 100 mega-pascals (MPa).   
     
     
         7 . The method according to  claim 1 ,
 wherein said grinding particle has a hardness higher than a work piece to be polished.
