|CENTRIFUGAL MAGNETIC FINISHER
Magnetic finishing presents itself as the pinnacle of methods to efficiently burnish and polish small non-ferrous metals such as gold and silver. With steel media as small as .010" in diameter and .25" in length, this finisher is able to work in areas such as undercuts, recesses, slots, etc. No other method works as well.
Centrifugal magnetic tumbler is quiet compared to other forms of finishing. Typically on soft, non-ferrous metals, the finishing cycle can be as short as 30 minutes. This alone assures a faster turn around time on parts compared to any other method.
Centrifugal magnetic finishing addresses the most intricate and detailed parts imaginable.
It should be noted that on any large, smooth, flat surfaces the finish will appear frosted. A light buffing or a run through a dry tumbler is recommended.
A centrifugal magnetic finisher is a direct drive, fan cooled design. The magnetic disk is made up of many powerful magnets that are precisely placed on a cast disk. The alternating polarity is constantly changing, thereby allowing the media to move freely in a liquid solution that is constantly changing its makeup. This combined with the centrifugal force allows for super quiet and fast time cycles.
The MT-03 centrifugal magnetic finisher features a 5-1/8" diameter clear removable bowl that will hold 10 to 22 rings. The unit measures approximately 12-7/8"H x 7-1/2"W x 8-3/8"D (with bowl) and weighs about 22lbs. It has a 60 minute timer, on/off switch with indicator. It is powered by a 90watt motor.
Approximately 90g of 0.8mm magnetic pins are included.
How does a magnetic tumbler work?
A magnetic tumbler uses thousands of teeny tiny little steel pins to do its job. These pins (just a fraction of a millimeter in diameter) act like thousands of little hammers that pound against the surface of your jewelry. They are burnishing your pieces but on a very small scale. The pins can get into the smallest and crevices. The result is a piece that is bright and shiny, work-hardened and finished while you did other work, and its all done more quickly that rotary or vibratory tumblers. Also there is no loss of metal since the burnishing is not an abrasive process.
