Field of the Invention The present invention relates to a lubricating oil composition suitable for lubricating a sliding guide surface of a machine tool or the like. The lubricating oil composition of the present invention is particularly preferably used for a machine tool which has a low feed rate and which requires highly accurate machining.

【０００３】しかし、滑り案内面を有する工作機械では
案内面に発生する摩擦抵抗のため、送り系に弾性歪みが
発生し、位置決め精度を低下させる。However, in a machine tool having a sliding guide surface, due to the frictional resistance generated on the guide surface, elastic strain is generated in the feed system, which deteriorates the positioning accuracy.

Oil and fat esters, sulfurized oil and fats, fatty acids, phosphoric acid esters and the like are added to the lubricating base oil in an amount of 0.1 to 10% by weight.

た。However, the conventional lubricating oil composition has not yet obtained sufficient lubricity for a machine tool that requires highly accurate machining. In order to obtain the required lubricity, it was necessary to blend an active friction reducing agent having high reactivity or to increase the addition concentration of these friction reducing agents. There is a problem that the cost of the lubricant composition increases when a large amount of the friction reducing agent is used. Further, when a highly active friction reducing agent such as a fatty acid or a phosphoric acid ester is used at a high concentration, corrosion may occur in machine materials such as a guide surface of a machine tool and an oil supply system.

In accordance with the minimum setting unit feed test method for vertical machining centers in Section 338-2.8, the Y axis is instructed to perform minute feed 1 micron in the plus direction every 10 seconds for a total of 25 times, and thereafter, Then, it was instructed to perform the same minute feed intermittently in the negative direction. The actual amount of movement was measured with a laser length measuring machine, and the response accuracy of the feed shaft of the machining center to a series of numerical control commands was examined by changing the lubricating oil. The feed accuracy is evaluated by measuring the number of command units required to actually start moving in the minus direction with respect to the command sent in the minus direction after sending in the plus direction, and compare the backlash of the minimum set unit feed. Went by. The test is carried out in a constant temperature room at 24 ± 0.2 ° C., and after sufficient running-in with the test oil to completely lubricate the lubricated surface with the test oil, the test oil is repeatedly repeated 6 times. The average value was calculated.

In comparison with each other, when a test oil containing a fatty acid, an acidic phosphoric acid ester or an alkylammonium salt thereof, or a phosphite ester and a linear alkylamine having a relatively large number of carbon atoms is used (Examples 1 to 8) It can be seen that in (), the backlash at the time of positioning is small and the positioning accuracy can be improved as compared with the case where the test oil containing no linear alkylamine is used (Comparative Examples 3 to 6, 9 and 10).
