Emulsion type metal cutting fluid

Abstract

The invention discloses an emulsion type metal cutting fluid which comprises the components based on parts by weight: 70-80 parts of mineral oil, 4-8 parts of diethanol amine, 4-8 parts of triethanol amine, 5-10 parts of lauryl sodium sulfate, 5-10 parts of laurinol polyoxyethylene ether, 10-18 parts of an antirust agent, 10-20 parts of a lubricating agent, 1-3 parts of a chelating agent, 2-4 parts of a bactericide, 0.05-0.2 part of a defoaming agent and 15-25 parts of water. The emulsion type metal cutting fluid has good lubrication action, cooling action and cleaning action, especially has excellent antirust action, and a protective film is formed on the surface of metal, so that a machine tool, a workpiece and a cutter are prevented from being corroded by the surrounding medium.

Description

technical field [0001] The invention relates to a cutting fluid, in particular to an emulsified metal cutting fluid. Background technique [0002] During the metal cutting process, the tool cuts into the material being processed to produce a cutting action. The material to be processed is pushed and rubbed by the rake face of the tool, and slides along a certain slope to produce plastic deformation and form chips. During the cutting process, the chips flow out of the machined surface along the tool surface at a very high pressure of up to 1800 MPa and at a fairly fast speed, which not only produces a certain plastic deformation, but also acts on the back of the tool with a considerable elastic deformation resistance. knife face. Due to the plastic deformation of the metal, the friction between the chip and the rake face of the tool, and the friction between the machined surface and the flank face of the tool, a large amount of heat is generated during the cutting process. ...
