Executive Summary
Magnetic field-assisted finishing (MAF) is a machining process which utilizes a magnet, ferrous materials, abrasive materials, and an oil to create a ‘brush’ for polishing operations. The process allows automation of surface finishing without the need for manual polishing. However, the quality of the finishing is highly dependent on the brush composition. Researchers at Michigan State University have recently developed a new MAF composition that can can improve the final surface quality.
Description of the Technology
The technology is a brush composition for magnetic assisted polishing comprised of a carrier fluid (hydrocarbon oils, vegetable oils, esters, etc.), abrasive particles, magnetic particles and optionally a solid lubricant. Examples of solid lubricants include graphite and hexagonal boron nitride and others. A range of abrasive particles can be used such as iron oxide, steel, sand cubic boron nitride and silicon carbide. The patented technology contains claims for a method of finishing a surface workplace and syringe delivery system to deliver the brush composition.
