    摘要: The induction-heating apparatus of this invention contains a conductive member, a power source, and a first and a second induction coil connected to the power source and adapted for causing the conductive member to generate an induced current, the first and the second induction coil being parallelly connected. The induction coil is formed by winding a copper wire round a core in such a manner that the numbers of turns of the copper wire gradually decrease from the lowermost layer approximating most closely to the core to the upper layers. This heating apparatus has the thickness of the induction coil in the range of 0.2-0.8 mm. The gap between the induction coil and the conductive member is in the range of 0.5-4.0 mm. This heating apparatus has the induction coil thrust out of the conductive member. The induction coil is formed of a Litz wire.

    摘要: Herein disclosed is an electric discharge machine, by which, after the machining operation of a workpiece by an electrode has reached a predetermined position, the machining operation is further accomplished while rocking the electrode in a plane generally normal to the feeding direction of the workpiece for the machining operation. The workpiece has its respective portion uniformly machined by effecting the machining operation accompanied by the rocking motions for a preset period, e.g., either for a predetermined time period or a predetermined number of the rocking motions so that the precision of the finishing operation can be improved.

    摘要: An electrical discharge machine control device which controls the displacement of the relative positions of a machining electrode and a workpiece so that the relative positions of the electrode and workpiece are changed not only in the main direction in which the workpiece is machined with the electrode but also in a plane perpendicular to the Z-axis without rotating the electrode while a predetermined machining discharge gap is maintained between the electrode and the workpiece. The relative displacement in the perpendicular plane is displayed at an enlarged scale on an X-Y display device which may be a cathode-ray tube with the center of the displacement maintained at a predetermined origin point. An optical encoder detects the movement in the X-Y plane to provide a detection signal. The detection signal is applied through reversible counters to the horizontal and vertical deflection amplifiers of the display device.
