Novel Lubrication for MAF Processing


Executive Summary


Manual labor remains one of the most expensive operating costs for machine shops. This MSU-developed technology seeks to improve the use of Magnetic Field-Assisted Finishing (MAF) to reduce the amount of hand finishing, particularly for mold cavities. Additionally, this technology seeks to improve the lifetime of abrasive particles, ultimately reducing the consumable costs of MAF processing. The resulting surface finish of this process is demonstrably superior when compared to traditional MAF processing.


Description of Technology


Magnetic Field-Assisted finishing utilizes a magnetic base and a slurry of ferrous particles, abrasive particles, and machining oil. The slurry creates a brush when exposed to the magnetic field which is rigid and hard enough to machine aluminum, steels, and titanium. This invention improves upon this technique by introducing graphene nanoplatelets which ultimately promote cutting of materials as opposed to plowing or sliding. The ability for abrasives to cut allows for faster processing with a finer surface finish. The nanoplatelets also help ensure that all cutting edges of the abrasive particles are used, increasing their useful life.
