Abstract

The invention provides a method for treating a combination of a ferromagnetic tool and a magnetic cutting fluid through a pulsed magnetic field, and relates to the technical field of machining. The method specifically comprises the following steps: a water-based magnetic cutting fluid or an oil-based magnetic cutting fluid containing micro-nano ferromagnetic particles is prepared according to the magnetic strength of a tool material; the tool is magnetized through a pulse magnetizing method, so that the magnetic force of the magnetized tool is not smaller than the maximum centrifugal force borne by micro-nano ferromagnetic particles in the cutting fluid at the same position; the tool is installed on a machine tool spindle, cutting fluid is placed in a machine tool fluid storage tank, at least two cutting fluid nozzles are used for being aligned to the contact face of the tool and a workpiece at intervals, and the inner diameter of the nozzles is not smaller than three quarters of the cutting width of the tool; and the machine tool is started for machining. The problems that in the prior art, a method for strengthening the metal cutting tool is complex in process and not ideal in strengthening performance are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for combining a ferromagnetic tool with a pulsed magnetic field and a magnetic cutting fluid. Background technique [0002] Ferromagnetic materials such as cemented carbide and tool steel are widely used to make metal cutting tools. With the development of the manufacturing industry, the performance requirements of metal cutting tool materials in various fields are constantly improving. Due to the harsh and complicated metal cutting conditions, in During cutting, the temperature at the contact between the tool and the metal is high, which will inevitably cause severe tool wear and even failure. [0003] At present, the strengthening methods of metal cutting tools mainly include heat treatment, surface coating, and machining of fine structures, so as to improve the performance of the tool and prolong the service life of the tool. However, the heat treatment...
