1. Characteristics of Sol-Gel Ceramic Alumina
Microstructure:
The grains are extremely fine (100-500 nm), much smaller than traditional alumina abrasives.
Self-sharpening:
During grinding, the tiny grains continuously expose new sharp edges, maintaining cutting efficiency and extending tool life. Toughness:
The grains exhibit higher toughness (about double) compared to traditional fused alumina, reducing wear and improving durability.
Applications:
Ideal for grinding tough materials like tool steel, stainless steel, and heat-resistant alloys.
2. Features of Grinding Tools Made from Ceramic Alumina
High Cutting Efficiency:
Sharp grains enable deep cuts and high feed rates, doubling metal removal rates.
Shape Retention:
High toughness keeps the grinding wheel shape stable, ideal for precision and profile grinding.
Long Lifespan:
Lasts 5-10 times longer than traditional wheels, reducing replacement frequency.
Self-sharpening and Non-Clogging:
Maintains consistent performance with minimal dressing needed. Cost-Effective:
Superior to traditional wheels, cheaper than CBN or diamond, and compatible with standard equipment and fluids.
