Product Description

Product Description

HRC 20 medium hard alumina oxide abrasive cut off wheels

At present, in the professional metallographic laboratory, most of the cutting only uses one type of grinding wheel to cut metallographic samples of various materials and hardness..This unscientific method is not only inefficient, but also causes damage to the sample, or causes serious deformation of the sample layer, which is not easy to be completely eliminated in the subsequent grinding and polishing process, and affects the quality of metallographic sample preparation.

Series	Material	Scope of application	Linear velocity	Specification
A60	Alumina, resin-based	Extremely hard ferrous metal(HRC>55)	30~36m/s	150*12.7*0.5 200*22*0.8 250*32*1.5 300*32*2.0 350*32*2.5 400*32*3.0 450*32*3.2 508*50.8*4.0
A50	Alumina, resin-based	Hard ferrous metal(HRC44~55)	32~40m/s
