Grinding Wheels
Hongtuo's grinding wheels include CBN grinding wheels anddiamond wheels. Basic characteristics of these abrasive wheels include each featuring a high hardness, a high thermal conductivity, and high sharpness. In comparison to common grinding wheels, CBN and diamond grinding wheels offer a higher abrasive cutting efficiency. Because of that,this bonded abrasive tool is suitable for high efficiency and high rate grinding in modern machining works.
Hardness comparison of various abrasives is as followsIf you wish to purchase grinding wheels from us, apart from the basic size, we need to know the abrasive particle size, density and bonded agent type.
