ある。[Prior Art] Conventionally, as a method for electrolytic finishing a workpiece that has been subjected to wire cut electric discharge machining, there is a method disclosed in Japanese Patent Application Laid-open No. 62-18862, for example.
There is a disclosure in Publication No. 4. This finishing method is

た。[Problems to be Solved by the Invention] By the way, in this electrolytic finishing method, the electrolytic solution supplied from the legs is continuously supplied to the entire gap between the workpiece and the remaining material, and the electrolytic solution is supplied between the gaps between the workpiece and the remaining material. Since machining current is supplied, the entire surface to be machined of the workpiece is finished, the finishing area becomes large, and a power supply with a large current capacity is required to obtain the machining current at the specified current density. ,
This had the disadvantage of increasing costs. Furthermore, even if a jet of electrolyte at a constant pressure is supplied to the gap, the flow rate of the jet in the gap varies depending on the circumferential length of the workpiece (length of the workpiece circumference). The supply pressure of the electrolytic solution must be changed depending on the circumferential length, which is disadvantageous in that the jet flow control of the supplied electrolytic solution becomes complicated.

Since this program moves the work l along the same trajectory as when wire-cut electrical discharge machining was performed, the jet nozzle 34 is always located directly above the gap 16. That is, X table 5 and
By the movement of the table 7, the gap 16 is moved to be located directly below the jet nozzle 34, and the gap 16 and the jet nozzle 34 are moved.
The relative position of the gap 16 changes continuously along the trajectory of the gap 16.

It moves while being partially finished and is continuously finished. That is, the electrolytic solution supplied for a predetermined time at the origin position exists in the gap 16, but if a jet of electrolytic solution is further supplied at high speed to a part of the gap 16 in this state, it will overflow from other parts of the gap 16. A liquid flow and bubbles of the electrolyte are generated. Therefore, the machining current acts intensively on the gap 16 where fresh electrolyte without bubbles or machining debris is supplied, and the surface 1a to be machined in this area is intensively finished. It will move continuously as it moves.

装置等の構成が簡単となる。As described above, in the electrolytic finishing method according to the present invention, a jet of fresh electrolyte is applied to the gap 1 between the workpiece 1 and the remaining material 2.
6, and the machining current acts intensively on the facing surfaces of the workpiece 1 and the remaining material 2, where this fresh electrolyte is interposed, so that the finish machining area of the workpiece 1 becomes smaller and the machining current reaches the specified level. The processing current for obtaining the current density can be reduced, and the current capacity of the power supply device 14 can be reduced. Furthermore, since the jet of electrolyte is supplied from the jet nozzle 34 to a part of the gap 16, the jet of electrolyte is less likely to receive resistance in the gap 16, and the supply of electrolyte at a constant pressure allows the workpiece to be rotated for 10 cycles. Regardless of the length, it becomes easy to supply a jet of electrolyte at a constant flow rate, and the jet flow control and the configuration of the electrolyte supply device and the like become simple.

。According to this embodiment, the fresh electrolyte jet supplied to the gap 16 is discharged from the recess 20 through the hole 35 into the processing tank, so that almost no electrolyte in the gap 16 is supplied with the jet. It does not move, and there are many machining debris and air bubbles, so almost no machining current flows in this gap 16, and the machining current flows intensively to the part where the jet is supplied, and this part is finished machined. .
