2014-1-1A hydraulic surface grinding machine was used to carry out the grinding tests under cryogenic cooling and oil based conventional cooling. The surface grinder used in the experiment with liquid nitrogen delivery was shown in Fig. 1.To conduct the experiments, the work material is cut into 100 50 8 mm plates, and then the plates are fastened to the upper side of a piezo-electric transducer ...Discover More
1975-8-26An abrasive cut-off machine was modified to permit measurement of the shear force exerted by the grinding wheel as copper bars were severed at varying rates of feed. A 10 inch diameter x 116 inch TC 120 HRR wheel manufactured by the Carborundum Company was used in all the experiments. The wheel speed was kept constant at 2100 rpm.Discover More
