Frequently Asked Questions
When grinding, numerous hard abrasive grains of the grinding wheel or any other abrasive material affect the workpiece, as well as various cutting tools, ie remove a certain layer of metal. Coarse grains are used to change the shape, and fine-grained abrasives are used to obtain a smooth surface. When polishing it is smoothed, however, until the matte surface is leveled and brought to a glossy gloss, which is achieved by the use of fine-grained polishing agent, which removes a very thin layer of metal. It is not possible to distinguish clearly between sanding and polishing. Upon completion of these processes, the jewelry should be cleaned of any abrasive material. For this purpose, ultrasonic washing is most often used, with the addition of a suitable professional cleaning agent in the liquid (discussed in the section "Jewelry chemistry"), on an industrial scale steam cleaners, in individual cases, manual cleaning is possible.
Engraving is one of the oldest ways of working metal. Its essence is the drawing of a linear drawing or a relief on a material by means of a cutter. Nowadays, manual work on metal engraving has been largely replaced by engraving with the help of laser installations and other profile machines (this is discussed in the section "Laser technologies"). It is in this section that we discuss all the difficulties that a jeweler faces when performing manual engraving with a cutter. Starting from transferring the drawing to the desired metal or finished product, secure it before starting work. We also talk about the preparation of the tool, what kind of a die what job to do (Spitzstichel, Messerstichel, vestichtehel, Justirstichel, Flachstichel, Bolstichel, Fadenstichel). And we also brag about our achievements, photo works.
If you are a jeweler, you work with precious metals and inserts, you will eventually have your own methods of working with these materials. Doing the technology, one way or another, will do on your own and you will get to improve the technology or completely to a new non-standard method of processing. If you have these experiences and would like to share them, we invite you to discuss in this section. If you are working on new techniques borrowed from colleagues from other countries, you can also share here or in the Development Opportunities section.
