Cup Grinding Wheel
The diamond cup wheel is constructed from industrial diamond abrasives with grit sizes ranging from 30/40 to 80/100 mesh. These abrasive particles are held in a resin or metal bond matrix at a concentration of 25 to 50 percent. The common outer diameter for these wheels spans from 100 mm to 300 mm. The cup depth or segment height varies between 10 mm and 40 mm. The permissible peripheral operating speed typically ranges from 25 to 35 meters per second. This tool is designed for grinding and finishing concave surfaces, complex profiles, and tile/ceramic edges. Its cup shape facilitates broader surface contact and delivers uniform material removal.
The wheel structure comprises three main layers: a steel core, a bonding interface, and the diamond abrasive layer. The central arbor hole is precision-machined to an H7 tolerance for secure spindle mounting. The side wall angle of the cup is between 5 and 15 degrees for accessing various profiles. This tool effectively grinds ultra-hard materials like ceramic, concrete, stone, and brick with Mohs hardness above 7. The optimal stock removal rate for granite is approximately 0.1 to 0.3 cubic centimeters per second. A continuous water cooling system is crucial to lower operational temperatures by up to 200 degrees Celsius. This process
