Abstract

The invention discloses a magnetizing cutter, a machining method and using method thereof, a cutting fluid and a preparation method, and relates to the technical fields of cutting tools and magnetic fluid preparation. Firstly, the cutter is magnetized, and then the surface texture morphology is machined on the cutter, wherein the surface texture morphology is micro-groove texture morphology or a flow guide groove; the surface texture morphology is filled with the magnetic fluid cutting fluid, wherein the magnetic fluid cutting fluid can be continuously added in the cutting process. The surfacetexture morphology can achieve the effects of flow guide, magnetic fluid storage, friction reduction and abrasion reduction. The defects that a solid lubricant cannot be supplemented after being consumed, and a cutting fluid in a traditional cutting fluid application method cannot reach the position, with the highest temperature, of a cutting edge are overcome. The durability and cutting efficiency of the cutter are improved, and the workpiece surface machining quality is ensured.

Description

technical field [0001] The invention relates to the field of mechanical cutting tool manufacturing technology and the preparation of magnetic fluid cutting fluid, in particular to a magnetized tool, a processing method and a use method, a cutting fluid and a preparation method, which are used to solve the problem that the cutting fluid cannot reach the highest temperature of the cutting edge and the use efficiency Low, leading to the problem of low tool durability and cutting efficiency in material processing. Background technique [0002] During the metal cutting process, the metal cutting layer produces plastic shear slip deformation under the extrusion of the tool, and the severe friction between the formed chips and the tool and workpiece, as well as the cutting heat, leads to tool wear and deformation. And reduce the cutting quality. Cutting fluid is usually used to assist cutting to achieve the functions of heat transfer, lubrication and cleaning. However, it is diffi...
