Technical Field
The invention relates to the technical field of turning tool cutting lubrication, in particular to a rolling type continuous micro-lubrication turning tool structure.
Background
In the cutting process of the turning tool, the cutting area is easy to bond with the tool body due to the action of high cutting force and high temperature conditions, so that the surface layer of the turning tool is severely worn, and the cutting performance and the service life of the turning tool are reduced. The traditional pouring type cutting uses a large amount of cutting fluid to pour into a cutting area for lubrication and cooling, which can effectively reduce the temperature of the cutting area, reduce the friction between a cutter and a workpiece, obtain a higher quality processing surface and reduce cutter abrasion. However, the use of a large amount of cutting fluid causes problems such as waste of cutting fluid and environmental pollution. Therefore, under the premise of ensuring normal lubrication of cutting, scholars at home and abroad propose a micro lubrication concept in order to reduce the use of cutting fluid.
Wherein: the self-lubricating cutter is a composite cutter which is prepared by directly adding a solid lubricant into a preparation material of the cutter and contains the solid lubricant, and the solid lubricant is separated out under the actions of friction, high temperature and the like in the cutting process, so that the lubricating effect is achieved. However, the addition of the solid lubricant deteriorates the mechanical properties of the tool material, limiting the range of use. The micro-texture self-lubricating cutter adopts a comparatively large number of modes at present, which is to process micro-textures with certain shapes and sizes in the front cutter surface area of a turning tool by utilizing methods such as laser processing and the like, then add solid lubricant into the micro-textures, the front cutter surface of the turning tool is subjected to the actions of cutting force and cutting heat, the solid lubricant in the micro-textures is separated out, a lubricating film is generated on chips, and the effects of lubrication and antifriction are achieved. However, as the solid lubricant in the microtexture is consumed, lubrication is not achieved when the solid lubricant is not retained in sufficient quantity. In order to solve the problem, some micro-channels are processed in the cutter to replace micro-textures, cutting fluid is directly fed into a cutter chip contact area through the micro-channels, so that lubrication of a cutter chip interface is realized, but the cutter is supplied with the cutting fluid through the micro-channels, so that the problem of waste caused by overflow of the cutting fluid is solved, and in addition, the cutting fluid is difficult to flow out due to the fact that the front cutter surface outlet of the micro-channels is easily blocked by chips in the cutting process.
