Description

technical field [0001] The invention relates to the field of processing high-strength steel aerospace structural parts, in particular to an oil-gas mixed jet lubrication milling technology for high-strength steel aerospace structural parts. Background technique [0002] In the traditional cutting process, heat and cutting chips will be generated. If the heat exceeds a certain range, it will cause adverse effects. Excessive accumulation of cutting chips will also cause blockage and affect the processing of the workpiece; [0003] Therefore, in the prior art, during the cutting process, it will continuously or indirectly follow the tool, spray mineral oil to achieve cooling, and at the same time, flush the cutting fluid; [0004] However, after the use of mineral oil, a large amount of mineral oil is extremely difficult to recycle and deal with, and waste mineral oil is a complex mixture of various substances, the main components of which are C15-C36 alkanes, polycyclic aromat...

Problems solved by technology

[0004] However, after the use of mineral oil, a large amount of mineral oil is extremely difficult to recycle and deal with, and waste mineral oil is a complex mixture of various substances, the main components of which are C15-C36 alkanes, polycyclic aromatic hydrocarbons (PAHS), olefins, Benzene series, phenols, etc., once entering the external environment, will cause serious environmental pollution;

[0005] Now a concept of dry cutting has been proposed in this technical field, but in practice, there are still many problems. It is basically a very unpopular field, and everyone is in the research and development stage;

[0006] In the field of aviation, such a problem is also involved. In this field, the utilization rate of high-strength steel is very high. Using traditional methods to process high-strength steel workpieces will also cause the above-mentioned pollution problem. Now in this dry cutting field , everyone is also trying, basically the most used is to set up a vortex tube, follow the movement of the tool, and spray cold air on the processing area, but in the actual use process, although the cooling effect is achieved, there will also be unstable products. The phenomenon of chipping occurs, and there are different dead angles in cooling and chip removal, resulting in extremely unstable processing, and the processing quality of high-strength steel workpieces in the aviation field cannot be guaranteed.
