  • To investigate the strengthening effect of calcium sulfate whiskers as a reinforcing filler for resin grinding tablets, experimental splines and resin grinding tablets were prepared by the hot pressing method. The effects of different whisker lengths and mass fraction on the hardness, bending strength and microstructures of the splines were examined, and the grinding performances of the grinding tablets on artificial granite were studied. The results show that when the mass fraction of the whisker is constant, the bending strength of the spline decreases with the increase of the whisker length, while the hardness remains relatively unchanged. One the other hand, when the whisker length keeps constant, the bending strength of the spline shows a trend of increasing and then decreasing with the increase of the whisker mass fraction. Using the grinding tablet to grind artificial granite, the best abrasion resistance of 1.973 min/% and good sharpness of 76.8 cm3/min are achieved when the length of calcium sulfate whisker ranges  from 10 to 60 μm and the mass fraction is 10%.
