Abstract

The invention discloses special lubricating grease for numerically-controlled machine tools and a preparation method of the special lubricating grease, and belongs to the technical field of special lubricating grease. The technical scheme adopted by the invention has the key points as follows: the special lubricating grease for the numerically-controlled machine tools is prepared from the following raw materials in parts by weight: 60-85 parts of base oil, 10-15 parts of a thickening agent, 3-8 parts of lithium hydroxide, 5-7 parts of dioctadecyl thiodipropionate, 2-5 parts of di-n-butyl phosphite, 2-5 parts of dithiophosphate and 2-5 parts of glycerine. The invention further particularly discloses the preparation method of the special lubricating grease for numerically-controlled machine tools. The lubricating grease prepared by the preparation method provided by the invention has the advantages of high temperature resistance, waterproofness, shear resistance and no carbon formation, and thus is especially suitable for lubrication of the numerically-controlled machine tools; properties of the lubricating grease in all aspects are greatly improved, so that the numerically-controlled machine tools are unlikely to break in the using process, and the running cost of equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of special lubricating grease, and in particular relates to a special lubricating grease for numerically controlled machine tools and a preparation method thereof. Background technique [0002] The lubrication system of CNC machine tools occupies a very important position in the whole machine tool. It not only has a lubricating effect, but also has a cooling effect, which is used to reduce the influence of the thermal deformation of the machine tool on the machining accuracy. The design, commissioning and maintenance of the lubrication system are of great significance to ensure the machining accuracy of the machine tool and prolong the service life of the machine tool. Grease lubrication does not require lubrication equipment, works reliably, does not need to add and replace grease frequently, and is easy to maintain, but the friction resistance is relatively large when using grease lubrication. The sealing...
