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)	Physical properties (grain size 60)	the offerable grain size	Code
Al2O3 (99.22%)   Na2O(0.08%)	Density   3.90(g/cm) Bulk density 1.82(g/cm) Crystal size 0.15 (m)	24-180#	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.
