PURPOSE:To improve the working efficiency by dressing a grindstone by the abrasive material during grinding work. CONSTITUTION:The grinding liquid mixed with minute-particulate abrasive material 12 for dressing is jetted from a nozzle to the grinding point of a ground material 2 and a metal-bond super abrasive-grain grindstone 1 in grinding work, and said abrasive material 12 is allowed to intrude into the gap between the abrasive grains 1a of the grindstone 1, and the chips and bonding agent which are gathered between the abrasive grains 1 are removed by lapping action. By the utilization of the abrasive material 12, the grindstone 1 can be dressing- worked without suspending the grinding work.
