ている。2. Description of the Related Art Conventionally, in the case of grinding with a metal bond grindstone, so-called electrolytic in-process dressing (ELI) is performed, in which electrolysis during grinding elutes the metal bond and thereby causes the abrasive grains to protrude.
D grinding: Electrolytic In-process Dressing) is known.

電位に設定するように構成されている。A dressing apparatus for performing this kind of electrolytic in-process dressing is provided with an electrode made of copper or the like which is arranged so as to face an outer peripheral abrasive grain surface of a metal bond grindstone, and a minute gap is provided between the electrode and the metal bond grindstone. Electrolytic grinding liquid is supplied from the nozzle to this minute gap, and the electrode is set to a negative (-) potential and the metal bond grindstone is set to a positive (+) potential.

砥石の砥粒を突き出させるための目立て(電解ドレッシ
ング)を行う。According to such a dressing device, during grinding of a workpiece with a metal bond grindstone, an electric current is applied between the metal bond grindstone and the electrode via an electrolytic grinding liquid, and the electrolysis caused by this energization causes an outer periphery of the metal bond grindstone. Metal dressing on the side of the abrasive grain surface is eluted, and thereby dressing (electrolytic dressing) for causing the abrasive grains of the metal bond grindstone to protrude is performed.

停止し、メタルボンド砥石による研削のみが行われる。Further, as the electrolytic dressing progresses to a certain level or more, an oxide film formed on the eluted portion of the metal bond grows, whereby the non-conductive oxide film is formed on the surface of the metal bond grindstone (excluding the abrasive grain portion). When formed, the current between the metal bond grindstone and the electrode is cut off, and the electrolysis due to the current is stopped, so that the electrolytic dressing is temporarily stopped and only the grinding with the metal bond grindstone is performed.

不導体酸化皮膜が形成され、メタルボンドの溶出により
砥粒の突出量も確保される。Further, when only the grinding by the metal bond grindstone proceeds while the electrolytic dressing is temporarily stopped, the abrasive grains of the metal bond grindstone are worn away, so that the non-conductive oxide film of the metal bond grindstone comes into sliding contact with the workpiece. Although it peels off, the peeled part becomes a conductor of the metal (metal bond), so current and electrolysis by current are restarted, which causes metal bond to elute, and a new non-conductive oxide film is formed there. The amount of protrusion of abrasive grains is also secured by elution of the metal bond.
【0007】以上のような形成・剥離のプロセスによ

さに保たれ、砥粒の突出量も一定の高さを保つことがで
きる。By the above-described forming / peeling process, the non-conductive oxide film of the metal bond grindstone is always kept at a constant thickness, and the projection amount of the abrasive grains can also be kept at a constant height.

粒面1aの大部分を電極2で覆わなければならない。When the conventional dressing apparatus as described above is applied to a small-diameter metal bond grindstone 1 made for an internal grinding machine as shown in FIG. 3 (a), for example, this kind of dressing apparatus is used. In the case of the small-diameter metal bond grindstone 1, since the non-conductive oxide film formed on the surface wears quickly,
In order to always keep the nonconductive oxide film at a constant thickness, most of the outer peripheral abrasive grain surface 1a must be covered with the electrode 2.

It is difficult to supply a sufficient amount of electrolytic grinding liquid, and in this respect also good electrolytic dressing (dressing) cannot be performed.
