The present disclosure provides a grinding wheel for grinding, configured such that a fiber-reinforced plastic (FRP) layer in a wheel outer peripheral part located on the outer surface of a wheel central part is provided at a position and thickness that vary depending on the type of weaving pattern layer, thereby exhibiting superior mechanical properties and superior vibration/shock absorption and offsetting effects compared to conventional grinding wheels, so problems such as cracking and fatigue failure due to burning do not occur, and moreover, the quality and productivity of processed products can be improved. Moreover, the grinding wheel is lighter in weight than conventional grinding wheels, and when an abrasive part is completely consumed, it can be replaced with a new abrasive part through removable attachment thereof, whereby the wheel outer peripheral part (wheel body) can be reused continuously, and the exchange time and the amount of tool wear can be reduced.
