Abstract

The invention discloses a nanofluid magnetic grinding fluid and a magnetic field-assisted micro-lubrication system. Magnetic iron ferric oxide nanoparticles in the nanofluid magnetic grinding fluid will be adsorbed on the surface of graphene to form magnetic lubrication mixed particles. The nano-fluid magnetic grinding fluid forms a spray under the action of the micro-lubrication device, and the magnetic lubrication mixed particles in the spray are evenly spread on the processing area of ​​the workpiece under the action of the magnetic field auxiliary device for lubrication and cooling. The magnetic lubrication mixed particles are collected by the recovery container , can be reused. The invention uses graphene as a lubricant, and combines magnetic effects and micro-lubrication technology to carry out lubrication and cooling, which can not only realize the efficient utilization of lubricants, greatly improve the lubrication and cooling effect, but also save energy and protect the environment, and meet the requirements of industrial production.

Description

technical field [0001] The invention belongs to the technical field of lubrication and cooling in grinding, and in particular relates to a nanofluid magnetic grinding fluid and a magnetic field-assisted micro-lubrication system. Background technique [0002] Grinding is the use of grinding wheels or other coated abrasives to process workpieces. Since the abrasive grains are usually cut with a negative rake angle during processing, a large amount of heat will be generated during the grinding process. During the grinding of difficult-to-machine materials, due to the high hardness and brittle characteristics of the material and poor thermal conductivity, the heat will be concentrated in the grinding area. If the heat cannot be exported in time, the temperature in the grinding area will rise sharply, which will not only cause grinding burns on the machined surface and affect the quality of the machined surface, but also the grinding wheel is prone to premature wear and scrap, a...
