TRUING AND DRESSING METHOD AND DEVICE THEREOF FOR CONDUCTIVE GRINDING WHEEL BY ELECTROLYTIC DRESSING GRINDING

摘要

PURPOSE:To reduce wearing of a truer grinding wheel by applying electrolytic dressing to a conductive grinding wheel part in a truer applying electrolytic dressing grinding to a conductive grinding wheel part of a grinding wheel to be trued. CONSTITUTION:A truer 8, having a conductive grinding wheel part 6, is mounted to a table 2. While a grinding wheel 12 to be trued, having a conductive grinding wheel part 10 rubbed with the grinding wheel part 6, is mounted to a rotary drive shaft 14. Switches SW2, SW1 are selected to a side A connecting an electrode 20, opposed facing to the grinding wheel part 6, and a power feed brush 22, coming into contact with the grinding wheel part 6, to a power source 24, when the drive shaft 14 is rotated while electrolytic dressing is applied to the grinding wheel part 6, truing is well applied to the conductive grinding wheel part of the grinding wheel 12. Next the switches SW1, SW2 are selected to a side B electrifying an electrode 28 and a brush 30, and electrolytic dressing is applied to the grinding wheel part 12 to be trued after truing. Accordingly, the truer grinding wheel 6 reduces its wearing.
