Kind Code:
B2
Abstract:
PURPOSE:To save manufacturing man-hour, while providing workmanship of high precision by employing a composite manufacturing unit comprising a wire-cut discharge machining device and a normal discharge machining device together with a standard machining electrode having a shape for facilitating the work process on an area to have minute notches. CONSTITUTION:Firstly, chips releasing back area is machined A workpiece 10 is placed on a machining table 7 with its front face in contact with the upper surface of said talk, namely with its bearing hole placed downward and the chips releasing back area facing upward. And the cutting process is executed in form of wire-cut discharge machining in compliance with an NC control employing a program in which the position and slant angle of a wire electrode 11 is preset for reserving a machining margin on the bearing surface. Then, the area to have minute notches is machined. The workpiece 10 is placed on the machining table 7 as it is and subjected to discharge machining by means of a machining head 26 with standard machining electrodes 20 through 24 mounted thereon. Finally, a bearing hole is machined with a wire electrode 11 arranged vertically to the table 7.
