What is the garnet cutting sand 80mesh for cutting glass
Garnet cutting sand is a natural minteral,selected from high quality almandine, with high hardness, high density, good toughness, sharp edges, is a high-grade, pure natural non-metal abrasive for blast cleaning and water-jet cutting.
Garnet sand, as a special abrasive for waterjet cutting, 80 mesh is a “universal grit size” for medium-hard non-metals such as glass and ceramics. It is finer than 60 mesh (reducing edge chipping) and more efficient than 120 mesh (avoiding excessively slow speed).80mesh decides its size range,which usually is 180-259microns.
Garnet cutting sand with a Mohs hardness of 7.5–8, it has sharp edges and strong grinding properties, can efficiently penetrate brittle materials such as glass, and has a small heat-affected zone, making it less prone to cracking or shattering.
