SG ( Sol Gel ) Grinding Wheel
Introduction of SG grinding wheel :
Ceramic abrasives prepared by sol-gel methodis 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 aseeded 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.

Applications of SG grinding wheel :
*Precisiongrinding 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 .
Our company also provides dressing rollers for dressing universal grinding wheels .
