Mass Finishing, Inc. (MFI) is a leading manufacturer of surface finishing equipment and supplies. MFI specializes in high-energy centrifugal barrel tumblers. These machines are capable of deburring and polishing all types of metals, plastics and other materials in just minutes compared to hours in other types of media tumbling equipment. For the racing industry, MFI has provided isotropic super-polishing on internal components such as camshafts, crankshafts and gears. These processes are also popular in aeronautics, medical and any other precision component industry. MFI supports a wide variety of traditional and non-traditional finishing processes and is committed to finding clients the best and most efficient solution.

Additive manufacturing is quickly becoming a feasible option for full-scale manufacturing. The combination of modern software, new materials and printer technology is allowing additive manufacturing or AM to bring efficiency and flexibility to manufacturing operations. The parts created using these processes are often left with very rough surfaces and scale and other imperfections. Companies using additive manufacturing need to come up with a quick solution for smoothing and polishing their parts.

3D Printing of models is often referred to as “Rapid Prototyping.” Using traditional hand polishing methods to improve the extremely rough surfaces of these parts is anything but “Rapid.” An operator can spend days to get all of the surfaces smoothed out by hand. Mass Finishing Centrifugal barrel tumblers can achieve a polish on several parts at once (Like the ones featured here) in just two hours.
