Segmented grinding wheel and manufacturing method therefor

A method for manufacturing a segmented grinding wheel of a construction that a plurality of segmented chips, each configured by bonding abrasive grains with a bond, are adhered to the circumferential surface of a disc-like core, whereby each of said segmented chips has circumferentially opposite end surfaces, the method comprising the steps of:

• filling a mold with granular material including abrasive grains;
• performing press-forming and burning to form a plurality of segmented chips;
• applying an adhesive layer made of a thermosetting resin onto said circumferentially opposite end surfaces of the segmented chips;
• after setting the adhesives at the circumferentially opposite end surfaces, adhering the plurality of segmented chips to the circumferential surface of the disc-like core by arranging the plurality of segmented chips on the circumferential surface of the disc-like core at regular intervals with a clearance between each segmented chip and the next thereto in the circumferential direction.
