step two: putting a glass fiber mesh into a mold of a grinding wheel; putting the mixed material on a well placed net piece; automatically spreading the materials; placing a mesh trademark and a core ring on the spread material to form a primary pah;
step three: cold press molding the grinding wheel peril;
step four: the formed grinding wheel and the shaped aluminum plate are penetrated together and sintered after solidification
Step five: and (4) sintering the grinding wheel to be solidified and sintered in a tunnel kiln, and sintering at different temperatures in sequence.
Step six: and naturally cooling to room temperature to obtain the finished product of the ultrahigh-speed resin grinding wheel.
Preferably, the abrasive is white corundum, the adhesive is phenolic resin, and the filler is cryolite, iron sulfide and calcium carbonate.
Preferably, the sintering at different temperatures is specifically: 4h at 50 ℃, 4h at 70 ℃, 4h at 90 ℃, 4h at 120 ℃, 4h at 150 ℃ and 10h at 180 ℃.
