PURPOSE:To conduct fastener joining completely and surely, by conducting the rough processing of a desired shape by means of grinding processing or a combination of grinding processing and another processing, and conducting precision finish processing by means of wire cut electric discharge machining. CONSTITUTION:Slide surfaces which slide each other by putting projecting streaks 2a, 2b or the like on grooves 1a, 1b or the like, are subjected to rough processing by means of grinding processing, and precision finish is conducted by means of wire cut electric discharge machining. A cutting-in quantity at the time of finish processing by means of this wire cut electric discharge machining is set so that projection and recess changes at the time of rough processing may be removed and a desired precision may be maintained, and smooth surfaces which are gotten rid of grinding grains and chips that intervene at grinding surfaces, are finished. And this precision finish processing is conducted not only for a base 1 but also for a slide piece 2, and sliding is made by putting streaks 2a, 2b of the piece 2 on grooves 1a, 1b of the base 1 thus finished in precision. As grinding chips and separated grinding grains are removed for slide surfaces, there is no wear of slide surfaces on account of the operation slide of a machine, and stable slide control can be maintained with a long service life. |
