Abstract

The invention provides a gas lubrication method and a cutting lubrication system acting on a blade-chip interface, and relates to the technical field of machining. A cutting lubrication method comprises the following step: conveying a gas lubricant, by a channel penetrating from a bottom surface of a blade to the blade-chip interface, to the blade-chip interface; the cutting lubrication system comprises the blade and a gas lubricant feeding system, wherein the blade comprises a blade body and a blade rod which are detachably connected with each other, the blade is internally provided with thechannel 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; and on the blade-chip interface of the blade, 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 the gas lubricant feeding system, 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, a circulating pipeline extends out from the lower end of the secondary cooling chamber, and a lower opening of the circulating pipeline is connected with the lubricant feeding system through an output pipe. The gas lubrication method and the cutting lubrication system provided by the invention have the beneficial effects of being excellent in lubrication effect and environmentally-friendly, and reducing the use of the lubricant.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a gas 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 tool-chip interface, 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 cutting fluid passes through the oil injection channel and is sprayed to the cutting part of the tool 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. It is easy to cause environmental pollution, because the cutting fluid is difficult to enter the knife-chip interfa...
