に関する。DETAILED DESCRIPTION OF THE INVENTION This invention removes burrs that occur when metal is processed using mechanical processing energy supply means by light abrasion with an abrasive and anodic elution using electrolytic action.
This invention relates to an electrolytic composite deburring method that effectively removes burrs.
一般に、金属を加工する際、バリの発生を極力
避けなければならないが、応々にしてバリが発生
する。たとえば、被削性の悪いステンレス鋼板に
穴あけ加工を行なうと、加工穴の周辺にバリが必
ず発生する。 Generally, when processing metal, it is necessary to avoid the generation of burrs as much as possible, but burrs are generated from time to time. For example, when drilling a hole in a stainless steel plate with poor machinability, burrs are inevitably generated around the drilled hole.

バリ取り手段とは云えない。 Incidentally, in order to remove the burrs, mechanical means such as filing or gliding, and electrolysis using an electrolytic barrel have been conventionally used. However, these deburring means are not effective in terms of productivity or economy when the workpiece has a large diameter or there are many burrs.

明する。 The present invention provides a method for removing burrs that solves the above-mentioned problems. After burrs of various shapes and sizes are uniformed in shape and size by light rubbing with an abrasive, the burrs are removed by electrolytic action. This invention is to remove burrs by anodic elution.Next, this invention will be explained in detail with reference to drawings showing embodiments thereof.

The voltage applied to the workpiece 8 and the tool body 1 needs to be approximately 2.5V, and if the abrasive material 4 is thick, the voltage must also be increased, but preferably 20V or less. In addition, the electrolytic solution 5 may include a neutral aqueous solution such as a passivated NaNO 3 aqueous solution of about 2 to 20%, or a workable NaNO 3 aqueous solution.
NaCI aqueous solution etc. are used. In addition, in practical results, the passivated type was better.

As shown in FIG. 3, when the abrasive material 4 passes through the part where the abrasive material 4 occurs, the burr A is tilted down or broken, and then, as shown in FIG. As the burr A passes through, the electrolytic current concentrates on the sharp and uniformly sized burr portion, and the burr A is easily eluted and removed by the anode.
なお、電源９として、直流断続電流を用いると
バリ部分に対する電解電流の集中度が向上する。 Note that if an intermittent DC current is used as the power source 9, the degree of concentration of the electrolytic current on the burr portion will be improved.
