SG Abrasive Grain F100 F120 for Diamond Wheels
Introduction of SG Abrasive Grain F100 F120 for Diamond Wheels
SG Abrasive Grain refers to a type of sol-gel alumina abrasive developed and commercialized by Norton (a leading abrasives manufacturer). It is a high-performance synthetic abrasive with a unique microstructure and excellent grinding performance, widely used in precision machining, tool grinding, and high-efficiency abrasive tools. SG Abrasive Grain F100 F120 for Diamond Wheels can improve the grinding efficiency and save cost.
The features of SG Abrasive Grain F100 F120 for Diamond Wheels
1. Small crystal size about 100-150nm, which is even much smaller than zirconia alumina. And it’s hundredths of the size of normal fused alumina grains.So it will make abrasive wheels increase lifetime by several times than ordinary wheels.
2. Excellent self-sharpening performance. The sol-gel grain will get new grinding edges after grinding. The edges are get from the single grain crystal instead of off a whole crystal. That makes the grain much sharper than normal fused alumina.
3. The microscopic hardness of sol-gel alumina is about 1900-2400 kgs/cm2,which is higher than zirconia alumina. Thus,sol-gel alumina can make grinding and cutting easier for special hard metal such as Nickel chromium alloy and nickel titanium alloy.
4. The roughness is double of normal fused alumina,and even higher than zirconia alumina.
5. Low temperature grinding is another significant property of Sol-gel alumina abrasive grain. That will avoid much heat during grinding and cutting, so it won’t get hurt of workpiece surface.
6. Small size grinding edges and sharp grinding can avoid tiny crackle on workpiece.
