Abstract
The invention discloses lubricating oil for metal processing. The lubricating oil is characterized by being prepared from the following components in parts by weight: 10 to 12 parts of base oil, 2 to 3 parts of inertia sulfur and 5 to 8 parts of glycerol derivative, wherein the base oil is at least one of mineral oil or synthetic oil. According to the lubricating oil for the metal processing, disclosed by the invention, a workpiece and a cutter can be cooled through heat conduction; the friction on a contact point is reduced by an additive in a lubricating oil composition, and a welding accident or a disastrous accident under high temperature or high pressure is prevented by an extreme pressure additive; under a gentle load or speed condition, boundary conditions play leading roles; but under a more extreme condition, the extreme pressure additive in processing liquid reacts with metal on the cutter and/or the workpiece to form a layer of firm film, and the film cannot be broken under high load/temperature/pressure conditions.
Description
Technical field
The present invention relates to intermetallic composite coating lubricating oil field.
Background technology
Intermetallic composite coating comprises a lot of operation, and in these operations, tool contact workpiece also changes profile or the shape of workpiece by the motion of cutter.In operation, a kind of metal working lubricant is added in the zone of action of cutter and workpiece.Metal working fluid has three kinds of main functions: the heat that the friction contact between cutter and workpiece produces removed; Reduce the friction during Contact of cutter and workpiece; Stop and to cause welding of cutter and workpiece because of the high temperature and high pressure at point of contact place.
Metal working fluid can realize the additive compound of above-mentioned advantage by various, according to the temperature and pressure of contact position between cutter and workpiece, metalworking operation runs under the admixture of so-called final condition, the above-mentioned two kinds of conditions of extreme pressure conditioned disjunction.The temperature that final condition finger contact area produces is not enough to state when brazed shank tool and workpiece.Boundary lubricant is fat or soap normally, and cutter can be made to be separated with workpiece and to reduce its frictional coefficient.When Contact Temperature and/or pressure increase exceed border additive available point, such as high in tool speed or increase cutting load time, so-called extreme-pressure additive is used.Under the high temperature of zone of action, extreme-pressure additive and cutter and workpiece surface react, and form a skim, prevent new surface breakdown or weld together in metallic surface.Known obtainable extreme-pressure additive reacts based on sulphur, chlorine or phosphorus and metallic surface.Extreme-pressure additive mixture can be used.
In order to extend cutting-tool's used life, increasing the surface light face quality of workpiece, various metal working fluid can be re-dubbed with boundary lubricant and the extreme-pressure additive containing sulphur, chlorine or phosphorus.Industrial always searching has in various metals processing occasion the metal working lubricant improving character.For complex operations, such as gear cutting is owing to producing high temperature and pressure between cutter and workpiece in gear cutting operating process, especially large to the needs of the lubricating oil improved.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, the intermetallic composite coating lubricating grease that a kind of cost is low, environmental pressure is little is provided.
The technical solution used in the present invention is: a kind of intermetallic composite coating lubricating oil, its component by weight:
Base oil 10 ~ 12 weight part
Inertia sulphur 2 ~ 3 weight part
Glycerol derivative 5 ~ 8 weight part
Described base oil is at least one in mineral oil or synthetic oil.
As a further improvement on the present invention, the kinematic viscosity of described lubricating oil 40 DEG C time is 90 ~ 220mm
2/ s.
The beneficial effect that the present invention adopts is: intermetallic composite coating lubricating oil of the present invention cools workpiece and cutter by thermal conduction.Additive in lubricating oil composition decreases the friction on point of contact, and welding when extreme-pressure additive prevents high temperature or high pressure or catastrophic failure.Under the load or velocity conditions of gentleness, final condition plays a major role, and under more extreme condition, and the metal on the extreme-pressure additive in working fluid and cutter and/or workpiece reacts, form the film that one deck is solid, can not be destroyed under high loading/temperature/pressure condition.
