Spray supply mode cutting oil for metal material cutting processing

Abstract

The invention relates to spray supply mode cutting oil for metal material cutting processing, which is prepared from the following raw materials in parts by weight: 40-60 parts of base oil, 30-40 parts of vulcanized fat and 10-20 parts of phosphoric acid ester, wherein the base oil is vegetable oil or synthetic ester or a mixture of the vegetable oil and the synthetic ester; since the consumptionof the vulcanized fat and the phosphoric acid ester used as extreme pressure additives of the cutting oil is large, the cutting oil has good extreme pressure lubricating performance, thereby ensuringthat process requirements are satisfied by consuming a minute quantity of cutting oil when the cutting oil is used for the cutting processing and spray oil supply of difficultly processed materials; and the adopted raw materials are biodegradable and have no toxicity to human bodies, small damage to ecological environment and low pollution.

Description

Technical field: [0001] The invention relates to the technical field of lubricating coolant for metal cutting, in particular to cutting oil in a spray supply mode for metal material cutting. Background technique: [0002] In metal cutting, metal cutting oils are usually used, the purpose of which is to prolong the life of drills, end mills, knives, abrasives and other tools used for processing, improve the surface accuracy of the processed object, and thus improve the processing efficiency. Efficiency, thereby improving the productivity of machining. [0003] Reasonable selection of cutting fluid can effectively reduce friction during cutting, improve heat dissipation conditions, reduce cutting force, cutting temperature and tool wear, improve tool durability and cutting efficiency, ensure machined surface quality and reduce product processing costs. [0004] In the traditional metal cutting process, a large amount of cutting fluid needs to be poured in the cutting area to ...

Problems solved by technology

Most of these materials are difficult-to-cut materials with poor machinability, which brings difficulties to the cutting process.

Among difficult-to-cut materials, some have a hardness as high as 65-70HRC, and their tensile strength is about three times higher than that of No. 45 steel (cutting reference steel), resulting in a cutting force that is 200% to 250% higher than that of No. 45 steel; sometimes The thermal conductivity of the material is only 1 / 4 to 1 / 7 or lower than that of No. 45 steel, which causes the heat in the cutting area to not be conducted quickly, forming a high cutting temperature and limiting the increase in cutting speed; some materials have high temperature hardness and strength High, the degree of work hardening of some materials is 50% to 200% higher than that of the matrix, and the hardening depth reaches 0.1 to 0.3mm, resulting in difficulties in cutting; some materials have high chemical activity, and have an affinity with the tool material during cutting, resulting in The tool produces severe bonding and diffusion wear; some materials have extremely small elastic modulus, large elastic recovery and large elongation, making it more difficult to cut
