By Raytech. Magnetic finishing is today's state-of-the-art process for burnishing and polishing ferrous materials. The process was born in the jewelry manufacturing market to meet certain demands and has grown into other markets. The machine is a direct drive, fan cooled design. The magnetic disk is made of many powerful magnets that are precisely placed in a cast disk. The alternation polarity is constantly changing, thereby allowing the media to move freely in a liquid solution that is constantly changing it's markup. This, combined with centrifugal force, allows for super quiet and fast time cycles. Magnetic finishing presents itself as the pinnacle of methods to efficiently burnish and polish small non-ferrous metals. With media as small as .010 in didameter and .250 in length, these stainless steel pins are able to work in areas such as undercuts, recesses, slots, etc., where no previous method has been found suitable. Centrifugal Magnetic Finishing is quiet by comparison to many other forms of finishing. Typically on soft, non-ferrous metals, the finishing cycle can be as low as 30 minutes. This alone assures faster turnaround time on parts when compared to any other method. Centrifugal magnetic tumbling is an automated process that addresses the most intricate and detailed parts imaginable in finishes where others fail. It should be noted that on large, smooth, or flat surfaces that the finish will appear frosted and a slight buffing or a run in a dry finisher is recommended. 400CMF & 610CMF units are complete with pins (.5mm) and compound.
