Access to grooves and small corners on the workpiece is often very limited. Preliminary cleaning and polishing of hard accessible corners can be done with magnetic polisher. Magnetic polishers are suitable for processing of silver and gold workpieces. Oxidation from previous processes can be easily removed.

The motor contained in the base of magnetic finisher spins a disc and this creates a magnetic field which in turn makes the magnetic steel pins jump randomly around the plastic pot. Speed regulation and automatic rotation inversion are optional. Included magnetic bar is used for separating magnetic pins from workpieces.

PM200 and PM200s incorporate acrylic housing whereas housing of PM500 is made from stainless steel.
