Abstract

The invention provides a cutting lubricating method directly acting on a tool-scrap interface and a cutting tool and relates to the technical field of machining. According to the method, a lubricant is directly conveyed to the tool-scrap interface through a passage penetrating to the tool-scrap interface from the tool and acts on tool cutting operation; the cutting tool comprises two parts of a tool body and a tool rod, the tool is internally provided with the passage penetrating to the tool-scrap interface of the tool body from the bottom face of the tool rod, and the passage is divided intoa micro passage body located in the tool body and vertical upper and lower sections a lubricating pipeline located on the tool rod; on the tool-scrap interface of the tool, a microtexture is arrangedwith an upper opening in the micro passage body as the center, and a lower opening of the lubricating pipeline is connected with a lubricant supplying system; a main cooling cavity is formed in the lower end of the micro passage body, a secondary cooling cavity is formed in the upper end of the micro passage body , and a circulating pipeline is arranged at the lower end of the secondary cooling cavity; and a lower opening of the circulating pipeline is connected with the lubricant supplying system. The cutting lubricating method has the beneficial effects that the lubricant directly acts on the tool-scrap interface, the lubricating and cooling effects are excellent, using of the lubricant is reduced, the cost is reduced, and environment protection is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a cutting lubrication method and a cutting tool directly acting on a knife-swarf interface. Background technique [0002] Cutting is accompanied by strong friction, which leads to the passivation of cutting tools, the deterioration of the quality of the working surface of the tool, and the large energy loss. In order to reduce the wear and friction of the tool during cutting and prolong the life of the tool, the cutting industry has begun to use a certain amount of lubrication When the cutting tool is cutting, the lubricant passes through the oil injection pipe and is sprayed to the cutting part of the tool to ease the friction and wear of the tool. However, the manufacture, use, treatment and discharge of the lubricant consume a lot of energy and resources, which is easy cause environmental pollution. With the continuous improvement of global environmental protect...
