| Message: | SG ( Sol Gel ) Grinding Wheel
Introduction of SG grinding wheel :
Ceramic abrasives prepared by sol-gel method is a kind of sintered abrasive , grain size is tiny, only 100- 500nm, hundredths of the size of ordinary corundum abrasive crystal. SG abrasive is high purity, ceramic aluminum oxide abrasive with a submicron crystalline structure deprived from a seeded gel sintering process. The grinding tools made of ceramic abrasive have the characteristic of long life , good self- sharp ability, high cutting efficiency, and low possibility of workpiece burning.
The parameters of Ceramic abrasives :
Main chemical composition(typical value) :Al2O3 (99.22%)Na2O(0.08%)
Physical properties(grain size 60):Density 3.90(g/cm³）Bulk density 1.82(g/cm³）Crystal size 0.15 (μm）
The offerable grain size:24-180#
Code:SG
Applications of SG grinding wheel :
* Precision grinding for unhardened and hardened steels,such as cast iron,carbon steels, alloy steels, and tool steels, etc.
* Internal grinding roller bearings, cylinders, compressor parts, gear parts, hydraulic and pneumatic cylinders etc.
* Grinding the crankshaft and camshaft of the engine and transmission of the car ; worm gear grinding .

Advantages of SG grinding wheel:
* Grinding wheel made of ceramic abrasive with has a higher durability and longer life, which is 5-10 times than the grinding wheel made of common corundum.
*Sharp grains , good cutting ability, and high grinding efficiency .
* Good self- sharp ability, microcrystalline structure Benefits ;
* Very good cutting capability, sharp grains;
* High removal rate& extended wheel life .
