ABRASIVE TECHNICAL INFORMATION MC Finishing

2021-6-28  ABRASIVE HARDNESS Abrasive minerals are chosen by their hardness. The basic abrading principle is a harder material chipping, abrading, or wearing away a softer workpiece material. The abrasive minerals generally run between 7 and 10 on the Mohs scale. Below is a chart on abrasive mineral hardness Hardness Comparison

Effects of abrasive material and hardness of grinding

2020-8-15  Abrasive material and hardness of grinding wheel are two important factors affecting the grinding efficiency and quality. In this study, two kinds of abrasive grains (i.e., zirconium corundum (ZA) and brown fused alumina (BA)) were used to produce eight grinding wheels, among which five with different contents of abrasive grains and four with different hardness levels.

Hardness testing insight Struers

Officially, hardness testing loads are expressed in Newton (N). However, historically, loads were expressed in kilogram-force (kgf), gram-force (gf), or pond (p). The correlation between kgf, kp, and N is: 1.0 kgf = 1,000 gf = 1.0 kp = 9.81 N. The term micro hardness testing is usually used when indentation loads are below or equal to 1 kgf.

Indentation behavior of creep-feed grinding induced

Both hardness and elastic modulus increase sharply in the climbing stage (h < 20 nm) and then become stable. The largest hardness of 10.5 GPa and the highest elastic modulus of 220 GPa are achieved in SDL (Fig. 2d). These indicates that the mechanical properties of surface layer are enhanced by grinding.
