Problems solved by technology
[0008] One of the technical problems to be solved by the present invention is that some lubricating oil compositions for honing process in the prior art use base oils containing light diesel oil and other components, and it is difficult to guarantee the safety of use; some use chlorinated paraffin extreme pressure lubricants , Barium-containing anti-rust additives, which have a certain impact on the environment, provide a new lubricating oil composition

[0024] First add the base oil into the blending tank, start the agitator and the heating switch, and stir while heating. When the temperature of the oil is heated to 45°C, add the rust inhibitor and antioxidant, and stir for 40 minutes; at 40°C Add long-chain fatty acid, phosphorus-containing extreme pressure agent and other additives, and stir for 80 minutes to obtain a uniform yellow liquid. Each component and its content are shown in Table 1, and its corresponding performance indicators are shown in Table 3.

The invention relates to a lubricating oil composition and use thereof, and is mainly used for solving the problems that the use security is difficult to guarantee since a plurality of lubricating oil compositions for a honing process in the prior art use base oil containing light diesel oil and the like, and a plurality of lubricating oil compositions using chlorinated paraffin extreme-pressure lubricants and barium-containing antirust additives have a certain influence to the environment. The problems are well solved by the technical scheme that the lubricating oil composition comprises the following components in parts by weight: a) 0.5-6 parts of long-chain fatty acid, b) 0.1-4 parts of phosphorus-containing lubricant, c) 0.5-5 parts of antirust agent, d) 0.1-3 parts of antioxidant, and e) 86-96 parts of base oil, wherein the base oil does not contain light diesel oil, and the composition does not contain at least one of the chlorinated paraffin extreme-pressure lubricant or barium-containing antirust additive. The lubricating oil composition can be used for lubricating, cooling and rust prevention in the metal honing process.
Description
technical field [0001] The invention relates to a lubricating oil composition for honing technology and its application. Background technique [0002] Honing is a commonly used finishing process for the inner wall of a hole and is a special form of metal cutting. It can not only remove a large machining allowance, but also improve the precision and surface quality of the workpiece. Through honing, workpieces with high dimensional accuracy, high shape accuracy, low roughness, and cross-texture on the surface of the inner hole can be obtained. In mass production, honing has the characteristics of low cost and high precision, and is an essential part of modern manufacturing cells. [0003] In order to ensure high dimensional accuracy, high shape accuracy and low surface roughness of the metal parts after honing, the lubricant needs to have good lubricity. Corresponding to the laboratory test, it shows a higher maximum non-jamming load and a higher Small wear scar diameter. ...
