A jewelry rolling mill machine is for life if it is looked after properly, let’s get to the maintenance side of things to keep the roller working the same way it did when it was purchased. There are a few do’s and don’t that I have been taught and stuck to.
At the end of the day in the workshop, take an old rag covered in oil; machine oil, cooking oil, motor oil, boiled linseed oil or tung oil are all good to use. Place the oil covered rag on the rollers while turning the cranking handle to cover the majority of both rollers in a layer of oil. This will ensure that traces of moisture that might have been missed won’t cause corrosion.
Cover the rolling mill with a drape when it is not being used; sunlight, dust and air moisture motivate corrosion as well, this will definitely extend the longevity of the machinery.
Avoid rolling anything wet through the rollers, water promotes corrosion. Keep a dry cloth next to to the station where you have annealed and quenched the metal before rolling it through. The same goes for imprinting textures onto a metal sheet; for example, a leaf imprint should be created with a dried out leaf instead of a fresh leaf one that has moisture in it.
