Main applications of pink aluminum oxide

1.Used for precision grinding of measuring tools, lathe main shafts, instruments and apparatus parts, threading work pieces and many other applications in grinding like flute grinding, tooth grinding, dry grinding of blade segments, tool and internal grinding and mounted point

2. Best suitable for high alloy steel applications, ideal for tool sharpening such as high speed steel cutters, reamers, chisels, end mill and sharpening band saw blades. Pink fused alumina is also recommended for knife-sharpening applications, working non-ferrous metals and the alloys.

3.good performance for vitrified bonded abrasives , vitrified grinding wheels, coated abrasives and blasting abrasives,

4.Used for softer materials, such as wood, Synth-etics, etc.
