ABSTRACT:
An improved turntable of a nylon fiber grinding wheel, which is integrally made of plastic by injection has a predetermined amount of flexibility. The turntable has a locking hole provided at a center portion therethrough, and a ring groove encircling the locking hole on a top surface of the turntable. The ring groove has a plurality of through slot arranged spacedly and radially and defines a plurality of ribs arranged radially and respectively between the through slots. A bottom surface recess of the turntable and ring groove are overfilled with a gluing agent such as epoxy resin, so that the gluing agent would also fill in the plurality of through slots and enwrap around the plurality of ribs. Therefore, a nylon fiber grinding plate can be attached to the bottom surface recess of the turntable by means of the gluing agent. As the gluing agent is enwrapped around the plurality of ribs around the through slot, the solidified gluing agent would be in an I-shape which ensures a rigid connection between the turntable and the nylon fiber grinding plate as strong as being riveted. Therefore, the resistance force contract the torque force generated by the turning motion between the grinding surface and the working surface is increased, and thus the maximum turning speed of the whole grinding wheel can be also increased.
