Why SG abrasives can be used to make grinding head?
SG abrasives is a high-end material used in the production of grinding heads. Grinding heads made with SG abrasive boast 40-50% higher grinding force than ordinary corundum and twice the toughness.
SG abrasive (microcrystalline corundum) is suitable for grinding heads due to its unique microstructure and superior properties:
The microcrystalline structure enhances cutting performance
SG abrasives is composed of a large number of submicron aluminum oxide crystals sintered together, continuously exposing new cutting edges during grinding, resulting in enhanced self-sharpening properties. This structure improves cutting efficiency by 40%-50% when machining difficult-to-machine materials (such as aerospace alloys and forged steel), while minimizing workpiece burns and metallographic damage.
Wear Resistance and Toughness Advantages
SG abrasive has a toughness over twice that of ordinary corundum and a similar hardness, but exhibits superior wear resistance. This property extends the life of grinding heads in precision machining, reducing maintenance downtime.
Applications
SG abrasives is suitable for applications requiring high surface quality, such as dental restorations and precision molds. For example, dental grinding wheel heads are made of silicon carbide or diamond coating, but ordinary abrasives are difficult to meet the needs of fine polishing. It can achieve more precise cutting control due to their submicron crystal structure.
