PURPOSE:To flat working surface by a method wherein the superposing allowance of a grinding tool is kept within a predetermined amount in the working employing the grinding tool in which a flexible abrasive material is attached to a rotary disc electrode. CONSTITUTION:The electrolytic compound working of the work of flat surface is effected by the grinding tool in which the abrasive material, having insulating, water permeating and flexible properties, is attached to the surface of the rotary disc electrode. When the width of the superposing allowance between the working path of the grinding tool of a diameter (b) and the subsequent working surface is denoted by a sign (c), the flatness of the working surface is varied in accordance with the superposing allowance (c) and is improved by keeping the allowance (c) within the range of 10<c<30%. |
