Abstract

The invention provides a liquid lubrication method and a cutting lubrication system directly acting on a blade-chip interface, and relates to the technical field of machining. A channel penetrating from a bottom surface of a blade to the blade-chip interface conveys a liquid lubricant to the blade-chip interface; the cutting lubrication system comprises a blade body and a blade rod which are detachably connected with each other, and is internally provided with the channel penetrating from the bottom surface to the blade-chip interface, and the channel comprises a micro-channel positioned within a range of the blade body and a lubrication pipeline positioned within a range of the blade rod; micro-texture is arranged by taking an upper opening of the micro-channel as a center; a lower opening of a lubrication channel is connected with a liquid lubricant feeding system; and the lower end of the micro-channel is provided with a primary cooling chamber, the upper end of the lubrication channel is provided with a secondary cooling chamber adapted to the primary cooling chamber, a circulating pipeline extends out from the lower end of the secondary cooling chamber, a lower opening of thecirculating pipeline is positioned on a bottom surface of the blade rod, and the circulating pipeline is detachably connected with the liquid lubricant feeding system through an output pipe. The liquid lubrication method and the cutting lubrication system provided by the invention have the beneficial effects of directly acting on the blade-chip interface, reducing the cutting cost, and being environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a liquid lubrication method and a cutting lubrication system acting on a knife-chip interface. Background technique [0002] Cutting is accompanied by strong friction, which leads to the passivation of the cutting tool, 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. When the cutting tool is cut, the cutting fluid with lubricating effect is used. The lubricant is sprayed to the cutting part of the tool through the oil injection pipe to alleviate the friction and wear of the tool to a certain extent. However, the manufacture, use, treatment and discharge of the cutting fluid consume a lot of energy. energy and resources, which are likely to cause environmental pollution. With the continuous improvement of global enviro...
