ML30 curved tube polishing machine

ML30 tube finishing machine provides a smooth surface, which will deliver a perfect chromed surface. Company JGS, Portugal, produces water faucets for kitchens and bathrooms all made in brass. According to Mr Domingos, managing director, before having the final chromed faucet produced, finishing and polishing steps are essential to have a perfect result. Mr Maia, responsible for the finishing and polishing division of the factory, said that before purchasing an ML30 tube finishing machine this step was done manually by an operator who worked with a stationary belt grinder. The faucet has to be turned several times in order to polish all sides and curves of the product. With the ML30 round tube polishing machine the operator simply feeds the tube through the machine following the curves of the faucet through the planetary station. The flexibility of the

THEML30 round tube polishing machine is the ideal equipment for polishing small diameter round tubes with tight bend radius. One of the challenges tube fabricators say they experience is not being able to automatically finish tubular components after they’ve been bent or end-formed. The tube’s surface can get scratched or gouged as it is clamped and handled during bending. With ML planetary machines the grinding and finishing process can be applied after the tube has been bent. Actually the tube does not have to be perfectly round – with ML30 planetary machine tubes that have an irregular-shape can also be processed. This is the case of water taps and faucets finishing, where the pipes have to be polished all around inside and outside the bend. Kitchen and bathroom faucets often need to be chrome plated and the

planetary system enables a perfect adaptability to different types of bent tubes. This change in the faucet finishing production dramatically dropped the production time, having increased three times the production of several faucet models, explained Mr Maia. Also, as the abrasives are rotating all around the tube, the finishing is always consistent, which becomes evident after chrome plating the faucets.
