Abstract

A fiber grinding wheel grinding fluid and its application relate to a fiber grinding wheel sharpening. It uses the commonly used chemical synthesis liquid containing surface active substances as the main component and does not contain sodium nitrite as the grinding stock solution. It is characterized in that it uses this soluble grinding liquid, adding water and free abrasive particles (free grinding) particles) mixed composition. The dilution ratio of grinding stock solution and water is 1:50, the diameter of free abrasive grains is 0.1-0.3 μm smaller than that of fibers in the fiber grinding wheel using grinding fluid, and the weight percentage of free abrasive grains added is 0.1-0.5%. Free abrasive grains can be white corundum (WA) or SiO 2 Or MgO or glass beads (Glass beads), also can be the combination of two kinds; The present invention has realized on-line sharpening grinding wheel grinding surface and prevents the generation of clogging, sticking phenomenon, has improved grinding capacity, grinding efficiency and can It can complete various fine grinding tasks in a short time.

Description

technical field [0001] A fiber grinding wheel grinding fluid and its application belong to the field of abrasives, abrasive tools and grinding in machine tool technology, and in particular relate to a method for sharpening fiber grinding wheels. Background technique [0002] In recent years, the development of new fiber materials has made great progress in various applications. Among them, the special Al 2 o 3 , SiO 2 , SiC and TiC short fibers, hundreds of nanometers to several micrometers in diameter, tens of micrometers to hundreds of micrometers in length, shaped like needles. Because of their excellent mechanical and physical and chemical properties such as high strength, high elastic modulus, wear resistance, high temperature oxidation resistance, acid resistance, alkali resistance, etc., and good compatibility with matrix materials, they are widely used in metal materials. Strengthening (reinforcement, toughening) materials such as , ceramics and plastics. Based ...
