Cutting oil

Abstract

The invention discloses cutting oil, which comprises the following components in percentage by mass: 40 to 60 percent of liquid paraffin, 20 to 50 percent of oiliness improver, 4 to 18 percent of extreme-pressure additive and 0.1 to 2 percent of benzotriazole, wherein the oiliness improver is a mixture of 30 to 90 percent of tricaprylin and 10 to 70 percent of glycol ethyl ether. The invention provides the cutting oil which has good effects of lubricating, cooling, rust protection and cleaning and has good environment-friendly performance.

Description

technical field

[0001] The invention belongs to the field of metal processing, in particular to a cutting oil used in the metal processing process. Background technique

[0002] Cutting oil is an indispensable process material in metal processing. The reasonable use of cutting oil in the cutting process can effectively reduce the friction between the tool and the workpiece during the cutting process, improve the heat dissipation conditions, thereby reducing the cutting force, power consumption, cutting temperature and tool wear, and prolong the service life of the tool. With the continuous development of modern metal cutting technology, processing equipment is developing in the direction of high speed, high function and automation, and the workpiece material has become superhard and diversified, which increases the difficulty of processing, and the requirements for cutting oil performance are increasing. In addition, due to the improvement of people's awareness of environme...
