ONE-TOUCH SWIVEL APPARATUS IN BOTH-SIDE AND ONE-SIDE LAPPING MACHINE, POLISHING MACHINE AND FINE GRINDING MACHINE INCLUDING ELECTRICAL AND CHEMICAL POLISHING

摘要

PURPOSE:To perfectly provide both functions of a both-side processing machine and a one-side processing machine as well as to enable free selection thereof, by a method wherein the column of a lapping machine or the like is separated into a upper part and a lower part as well as a special bearing is used. CONSTITUTION:The upper plate 4 of a both-side and a one-side lapping machine, a polishing machine and a fine grinding machine including electrical and chemical polishing receives the rotary power and the pressure of an upper drive shaft 5 and polishes the upper surface of an object 6 to be processed. The object 6 to be processed is fixed by a work carrier 7 and the lower plate 8 of the lapping machine or the like polishes the under surface of the object 6 to be processed by the rotary power of a lower drive shaft 10. A column is separated into an upper column 1 and a lower column 2 and the upper column 1 including the upper plate 4 is made possible to be revolved 90 deg. to a left and a right directions by a special bearing 3 to provide both functions of a both-side processing machine and a one-side processing machine as well as to enable free selection thereof.
