Grinding Wheel For Grinding

Abstract

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 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.

1 . A grinding wheel, comprising:
 a wheel central part comprising steel; and   a wheel outer peripheral part provided on an outer surface of the wheel central part and configured such that a fiber-reinforced plastic (FRP) layer is laminated and joined in a plurality of plies in a direction perpendicular to the outer surface of the wheel central part,   wherein the fiber-reinforced plastic (FRP) layer has at least one weaving pattern layer selected from among a woven fabric layer and a unidirectional fabric layer, and wherein a fiber bundle of the fiber-reinforced plastic (FRP) layer comprises 1k to 24k strands of yard per ply.   
     
     
         2 . The grinding wheel of  claim 1 , wherein the fiber-reinforced plastic layer comprises at least one selected from the group consisting of carbon-fiber-reinforced plastic (CFRP), glass-fiber-reinforced plastic (GFRP), and aramid-fiber-reinforced plastic (AFRP). 
     
     
         3 . The grinding wheel of  claim 1 , wherein the woven fabric layer is woven in a plain weave. 
     
     
         4 . The grinding wheel of  claim 1 , further comprising an abrasive part provided on an outer surface of the wheel outer peripheral part and comprising an abrasive.
