Ceramic abrasives prepared by sol-gel method is a kind of sintered abrasive , grain size is tiny, only 100- 500nm. SG abrasive is high purity, ceramic aluminum oxide abrasive with a submicron crystalline structure deprived from a seeded gel sintering process.
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/cm³） Bulk density : 1.82(g/cm³） Crystal size : 0.15 (μm） | 24-180# | s |
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 .
