Scope and Purpose 1, for non-ferrous and light-ferrous metals, hard plastic, stainless steel, copper, aluminum, zinc, magnesium, tin, gold, silver and other materials, precision grinding size parts cleaning, removal of burrs, chamfering, polishing and other work at once. 2, irregular parts, bore, inner tubes, corners, cracks, remove fine burrs and other internal and external thread processing. 1, machining, corrosion, oxidation, and process black polished workpiece with burrs. 2, lathes, stamping parts, cleaning, polishing and grinding twist oxide dental piece after heat treatment. It works magnetic polishing machine is to use powerful magnetic, conductive drive fine grinding needle, resulting in high spin float flow, vibration, reversing roll upward turn, over the surface, the inner hole, the inner and outer teeth and surface irregularities surface friction. Cleaning to remove grease contaminants, remove burrs, grinding, precision polishing effect. Features 1, a key start, automatic repeat, simple operation, a person operate several machines at the same time, safety, the human body without harm. 2, low cost of consumables, stainless steel needle for grinding material, the service life of 3--5 years. 3 speed, the average primary grinding 4-6 minutes, strong magnetic force, replacement parts quickly, without stopping the machine can be changed abrasive. 4, finished parts after grinding, no variation, no dead ends, do not damage the surface, does not affect accuracy. 5, clean, smooth machine is good, small energy-saving noise.
