Description
One, technical field
The invention belongs to technical field of mechanical cutting tool manufacture, particularly relate to compound texture self-lubricating sintex of a kind of micro-nano and preparation method thereof.
Two, background technology
Because the cutting fluid expense is higher, and causes environmental pollution, therefore, dry machining technology has become one of development trend of following metal cutting processing.But the dried also Shortcomings that cuts: owing to lack the lubrication and cooling effect of cutting fluid, the friction aggravation between cutter and the workpiece, cutting temperature raises, the serious wear of cutter, cutter life descends, and machined surface quality worsens.The good characteristics such as ceramic cutting tool material has that hardness height, wearability are good, heat resistance and chemical stability are good have become one of main cutting tools for cutting of doing cutting and difficult-to-machine material at present.But during high-speed dry cutting, the friction between the rake face upper slitter bits is unusually violent, has produced a large amount of heat, has caused the life-span of cutter to descend.So pollution-free in the urgent need to researching and developing, high efficiency novel lubricating mode, the friction when reducing high-speed dry cutting is to improve cutter life.
Self-lubricating knife tool refers to that cutter itself has antifriction and wear-resistant effect, and under the condition that does not add lubricating fluid or lubricant, cutter itself just has certain lubricating function, can improve the friction, lubrication state of dried working angles.The meaning that realizes the cutter self-lubricating is: can reduce friction, reduce to wear and tear, save cooling and lubricating system, overcome environmental pollution, the realization that cutting fluid causes and clean production.Therefore, can say that self-lubricating knife tool is a kind of dried cutting tool of cleaning.Chinese patent " application number 200710017168.3 " has been reported a kind of micro-chamber self-lubricating knife tool and preparation method thereof, it adopts fine electric spark to process micropore in cutter rake face cutter-bits contact zone, kollag is filled in the micropore, thus when cutting lubricant separate out and form lubricating film and play lubrication.Chinese patent " application number 201110089826.6 " has been reported a kind of little texture self-lubricating drilling bit and preparation method thereof, it is to adopt laser processing technology to process the little texture of groove or hole of different-shape in drill bit rake face cutter-bits contact zone, then in texture, fill kollag, thereby realize the self-lubricating function of drill bit.Chinese patent " application number: 201010124734.2 " has been reported the femtosecond laser preparation method of micro-nano composite texturing cutting tool by using, utilize the peculiar property of femtosecond laser and material interaction, carry out the compound texture preparation of micro-nano texture and little/receive at tool surface, improve the wear resistance of cutter, improved its service life.
Three, summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, compound texture self-lubricating sintex of a kind of micro-nano and preparation method thereof is provided.This sintex adopts on the laser processing technology rake face and processes micron order texture, process nanoscale texture at negative chamfered edge, and in micron order texture and nanoscale texture, fill kollag respectively, when doing smear metal, the double action of the compound texture of micro-nano and kollag can realize reducing friction, reduce cutting force and cutting temperature, bond, reduce friction, reduction wearing and tearing thereby can reach to stop, improve cutter life.
