Abstract
The grinding wheels containing 30% TiC and the conventional grinding wheels were tested to evaluate the mechanical grinding efficiency. And in case of the TiC wheels, the electro-mechanical grinding(EMG) test was also made to compare the grinding efficiency and the surface conditions with those of the mechanical test.Findings were as follows:The mechanical grinding efficiency of the wheels containing TiC was superior to that of the conventional wheels.Especially, the wheels containing a small amount of CBN (Cubic Boron Nitride) showed a high efficiency.The EMG test showed a higher efficiency compared with the only mechanical test under the same grinding conditions.Furthermore the better grinding surface was observed in case of the EMG test.A test under the condition of 5000rpm in rotational speeds and 865mA/cm2/in electrolytic current indicated the most suitable results.
