A DOME SUCCESS! NEW BOWL SHAPE IMPROVES FINISHING The Finishing Techniques MG12-V variable speed magnetic polishing machine is now available with a new octagonal shaped bowl to improve processing of small jewellery pieces. Until now, there has been a dead area created in the centre of the process bowl by the action of the rotating magnet where product can not be properly polished. The solution to this problem, though simple, is effective. A dome shape has been moulded into the base of the bowl. This is enough to ensure that product stays in the flow of media and away from the middle of the bowl so all product is evenly polished. Speed control is now enhanced to give manufacturers an even greater range of stepping from 0-1500 revolutions per minute. Practically, this means an effective but gentle polish starts at 400 rpm for delicate jewellery while more robust pieces receive a more aggressive treatment right up to 1500 rpm. Fine speed adjustments can also limit any impingement damage with delicate pieces or when processing mixed items at one time. Further control over the process is governed by time and the choice of pins used. All kinds of metal such as gold, silver, platinum and alloys (with or without stones) can be processed with negligible metal loss and without the need for dangerous toxic chemicals. The MG12-V can also eliminate the need for bombing and stripping machines. A typical user will place 300 grams of pins, up to 500 grams of gold or silver rings, broaches and so on into the 12 litre process container for 20-25 minutes. A timer control means the whole operation can be unsupervised. The MG12-V works off single phase mains. A range of pin sizes is also available from Finishing Techniques who will advise on the right choice for each application. For a list of distributors and technical advice call 01706 825819.
