On the other hand, it can cause clogging effect due to lack of grit generation by severe bond. Thereby, frequent dressing job is necessary while working in appropriate grinding condition. Because of its strong retention of grit and resistivity of abrasion, the bond wheel is accepted to profile grinding, which requires for no abrasion, long tool life, or strong object. There are various kinds of metal bond wheel such as bronze and iron group, which are the dominant numbers, cobalt group, tungsten group, and bond group. These are sintered by using an iron mold or a carbon mold after mixing with diamond and CBN powder.
