送しつつ処理を行うものであった。(Prior Art) The conventional electrolytic deburring method incorporates a water washing step between the electrolytic deburring step and the rustproofing step, and as shown in FIG. 2, each electrolytic deburring station (51) is independent. A washing station (52) and an anticorrosion station (53) are provided, and the work (54) is sequentially conveyed between these stations for processing.

いる。(Problems to be solved by the invention) However, in such a conventional method, since the work has to be transferred to each station, there is a risk of rust during the transfer, and the drainage treatment of washing water There are also problems that require equipment. Therefore, development of an electrolytic deburring method capable of performing electrolytic burring processing on a workpiece at the same station and then performing rust prevention treatment and omitting washing with water has been desired.

る。(Means for Solving the Problems) The present invention has been made in response to the above-mentioned long-awaited situation, and a working fluid in which an electrolytic solution and an anticorrosive solution containing a water-soluble salt as a main component are mixed is applied to an electrode. It is characterized in that a direct current is supplied while supplying a current to perform electrolytic deburring, and then the current is stopped and the same machining liquid is supplied to perform rust prevention treatment on the work.

の防錆液を加えたものが好ましい結果を示した。As described above, in the present invention, the working fluid in which the electrolytic solution and the rust preventive solution are mixed is used commonly in the electrolytic deburring step and the rust preventive step. As the rust preventive solution, a water-soluble salt that can be uniformly mixed with the electrolytic solution is used, and for example, a rust preventive solution containing sodium phosphate, sodium nitrite, or sodium carbonate as a main component is used. The mixing ratio is not particularly limited, but according to the experiments of the present inventor, for example, an electrolytic solution containing 20% to 40% of sodium nitrate and a rust preventive solution of about 5% are preferable results. showed that.

なお（９）は液面計である。Such a working fluid is contained in the working fluid tank (1) shown in FIG. 1, and the electrode (6) is passed through the filter (3), the flow meter (4) and the solenoid valve (5) by the pump (2). First, electrolytic deburring is performed while a direct current is supplied from the direct current power source (7). During this time, the working fluid discharged from the electrode (6) is guided to the centrifuge (8), where sludge is separated and returned to the original working fluid tank (1).
Note that (9) is a liquid level gauge.

ークを電極から取外して液切りを行うだけでよい。After the electrolytic deburring is performed in this way, the rust prevention treatment is performed by stopping the energization from the DC power source (7) while continuing to supply the working fluid. During this time, the circulation of the working liquid is performed in the same manner as in the electrolytic deburring process. After the rust prevention treatment, it is only necessary to remove the work from the electrode and drain the work.

Cast iron pieces of the same area in a processing solution bath containing 5% rust preventive solution (for example, sodium phosphate, sodium nitrite, and sodium carbonate as the main components) added to electrolyte containing 20% NO 3.
When electrolyzed at 300 coulombs, NaNO 3 is 20% as before.
The weight loss was 79.7 mg when only the electrolyte containing was used, and 68.6 mg according to the method of the present invention. In addition, the rust-preventing power was slightly better than that in the case of using rust-preventing oil, and it was confirmed that the rust-preventing power had no problem in practical use.

ころは極めて大である。(Effects of the Invention) As is clear from the above description, the present invention performs electrolytic deburring and rust-prevention treatment while the work is still attached to the electrode, so that the work can be transported and the work can be performed immediately after deburring. Since rust treatment is possible, it is not only suitable for works that are particularly prone to rust, but also because the washing step is omitted, the total treatment time can be shortened. Furthermore, since it is not necessary to treat the washing waste water, and since the working fluid has both electrolysis and rust preventive power, both works can be performed at the same position and the entire equipment can be downsized. Therefore, the present invention has an extremely great contribution to the development of industry by eliminating the problems of the conventional electrolytic deburring method.
