Abstract:
A method for producing a coil for electric apparatus of the present invention is the method for producing a coil for electric apparatus for cutting spirally a block-shaped workpiece formed with a cylindrical portion corresponding to the coil in a circumferential direction of the cylindrical portion, the spiral coil is formed by turning a cutting means while moving it relatively to the workpiece from a part corresponding to one end of the coil to a part corresponding the other end of the coil along a machining line spirally set in the circumferential direction of the cylindrical portion. According to the invention, since the coil is formed by cutting the continuous cutting machining plane without generating a step in design from the block-shaped workpiece formed with a cylindrical portion corresponding to the coil using a wire-tool etc., it is possible to constitute a high-quality coil.
