Metal pre-polish
Before the finishing step of the polishing process the surfaces have to be prepared. Therefore a pre-polishing step is used, for which high cutting compounds are used. A combination of high cutting and good polishing results, which can be achieved with Almatis aluminas can save time and money in the following finishing step.
