Cutting and grinding oil composition

Abstract

This cutting and grinding oil composition contains (A) 60-97 mass% of a lubricating-oil base oil, (B) 0.1-0.7 mass% of elemental sulfur, (C) 0.05-20 mass% of sulfurized fats and oils, and (D) 0.1-7 mass% of a polysulfide compound, based on the total amount of the composition.

Description

technical field [0001] The present invention relates to a cutting and grinding oil composition and a cutting and grinding method using the cutting and grinding oil composition. Background technique [0002] For cutting and grinding oils, the improvement of cutting and grinding performance is demanded in order to effectively perform a large amount of grinding and improve productivity. In recent years, the production of special stainless steels with high corrosion resistance is increasing, but they are relatively hard and difficult to grind, so further improvements in cutting or grinding performance are sought. In addition, grinding of stainless steel or the like is generally performed using a grinding belt to which abrasives are bonded, but when the abrasive of the grinding belt wears out, the amount of grinding decreases, and the belt is replaced at that time. Therefore, for cutting or grinding processing oil, cutting or grinding tools such as wear-resistant belts are also ...

AI Technical Summary

Problems solved by technology

Elemental sulfur has low solubility in lubricating oil, so only a small amount can be blended. When only elemental sulfur exists, the processing performance such as grinding performance cannot be sufficiently improved.

In particular, in low-temperature environments in winter, etc., there are problems of sulfur precipitation, deposition, and a decrease in the amount of dissolved sulfur, resulting in a decrease in processability.
