金属加工油組成物  Metalworking oil composition
技術分野 Technical field
本発明は金属加工油組成物に関し、 より詳しくは、 特に自動切削加 ェ盤用に好適な金属加工油組成物に関する。  The present invention relates to a metalworking oil composition, and more particularly to a metalworking oil composition particularly suitable for an automatic cutting machine.
背景技術 Background art
自動切削加工盤 (以下、 自動盤ともいう。 ) はガイ ドブッシュを備 えることにより細長物の切削加工を可能としている。 この自動盤にお いて、 通常の切削油を使用してステンレス鋼やチタン合金等を切削加 ェした場合、 ガイ ドブッシュ部がかじり(scuff i n g)を生じやすいとい う問題があった。 そこで従来から、 自動盤加工においては、 切削油剤 と しての用途に加え、 ガイ ドプッシュ部の潤滑剤の用途も兼ねる、 塩 素化パラフィン等の塩素系添加剤を多量に含有する切削油を用いるこ とにより、 ガイ ドプッシュ部のかじりを防止していた。  An automatic cutting machine (hereinafter also referred to as an automatic machine) is equipped with guide bushes to enable cutting of slender objects. In this automatic lathe, when a normal cutting oil is used to cut stainless steel, titanium alloy, or the like, there is a problem that the guide bushing portion is liable to be scuffed. Therefore, conventionally, in automatic lathe machining, a cutting oil containing a large amount of chlorine-based additives such as chlorinated paraffin, which is used not only as a cutting fluid but also as a lubricant for the guide push part, has been used. This prevented the guide push section from galling.
しかしながら、 近年では塩素化合物を配合した非水溶性切削油剤を 使用した場合、 焼却処理時のダイォキシンの発生による環境汚染や塩 素ガス発生による焼却炉の腐食 ·損傷の問題が指摘されている。 また、 塩素化合物のうち一部の塩素化パラフィンでは、 毒性及び発癌性の可 能性についての懸念も生じてきており、 非塩素系添加剤に切り替える 動きが強くなつている。  However, in recent years, it has been pointed out that when water-insoluble cutting fluids containing chlorine compounds are used, environmental pollution due to the generation of dioxins during incineration and corrosion and damage to incinerators due to the generation of chlorine gas. Concerns have also been raised about the toxicity and carcinogenic potential of some chlorinated paraffins of chlorine compounds, and there is a growing movement to switch to non-chlorine additives.
例えば、 特許第 2 6 4 1 2 0 3号公報、 特開平 6 — 3 3 0 0 7 6号 公報, 特開平 8 — 2 0 7 9 0号公報には、 過塩基性金属のスルホネー トと硫黄系極圧剤等を含有した切削加工油剤組成物について開示され ている。 しかし、 この油剤は一般的な金属加工において良好な加工性 能を示すが、 ステンレス鋼やチタン合金等の重切削加工においては、 充分な加工性能が得られない場合があるばかりでなく、 上記の自動盤 のガイ ドブッシュのかじりについての問題も解決されていないのが現 状である。 For example, Japanese Patent No. 2641203, JP-A-6-330076 and JP-A-8-29090 disclose sulfonate and sulfur of an overbased metal. It discloses a cutting oil composition containing a system extreme pressure agent and the like. However, this oil shows good workability in general metalworking, but not only does not provide sufficient workability in heavy cutting of stainless steel, titanium alloy, etc. Automatic lathe At present, the problem of galling of the guide bush has not been solved.
本発明は、上記観点からなされたもので、塩素系添加剤を含有せず、 ステンレス鋼やチタン合金等の重切削加工を可能と し、 かつ自動盤切 削加工時のガイ ドブッシュ部のかじりを防止する金属加工油組成物を 提供することを目的とするものである。 '  The present invention has been made from the above viewpoint, does not contain a chlorine-based additive, enables heavy cutting of stainless steel or titanium alloy, and reduces galling of a guide bush during automatic cutting. It is an object of the present invention to provide a metalworking oil composition for preventing such a problem. '
