Abstract

PURPOSE:To improve efficiency in production of a wrist watch case by cutting the workpiece cut off into a product thickness by using a chain multi-head type NC machine tool. CONSTITUTION:A hollow round or odd-shaped rod cut off into a product thickness is cut into a wrist watch case by using an NC lathe or other cutting machines. To produce the workpiece, following ways and means can be employed. (A) A round rod or the odd-shaped rod patterned after the band attaching portion is longitudinally cut off into a product thickness (round slices) by using an automatic cutter, and after its center portion is punched out by a press, its inner surface is cut into a given inside diameter by an NC lathe or the like. (B) A hollow round or odd-shaped rod is longitudinally cut off into a product thickness by an automatic cutter, and its inner surface is cut into a given inside diameter by an NC lathe or the like. (C) A round or odd-shaped rod, or a hollow round or odd-shaped rod is longitudinally cut off into a product thickness while its inner surface is being cut into a given inside diameter by an automatic cutter-cutting off machine. (D) After the periphery and center portion of a plate material of product thickness are punched out, its inner surface is cut into a given inside diameter by an NC lathe or the like.
