Introduction to Metallographic Grinding and Polishing
Metallographic grinding and polishing processes differ depending on the sample material. These differences usually affect the consumables required or the number of necessary grinding and polishing steps. For example, steel with a hardness between 35 and 65 HRC (medium-hard to hard steels) is relatively easy to prepare.

Design and Fabrication of a Continuous Polishing Machine
This paper aims to design and fabricate a polishing machine that performs polishing stages continuously, eliminating the idle time in the polishing process. The designed machine consists of four spindle heads, each of which carries a unique flap wheel. The flap wheels can raise or lower according to the size of the workpiece to be polished.
Process analysis of plasma-electrolytic polishing (PeP) of …
Plasma-electrolytic Polishing (PeP) is an innovative forceless ablation process based on environmentally friendly water-based electrolytes. Typical areas of PeP application are in deburring and surface smoothing for industrial, medical, micro- and nanotechnology and automotive/aerospace parts. In forming, a potential benefit of PeP …
Three more diamond cutters, polishers come to town
The Government has revealed three more diamond cutting and polishing companies will set up businesses locally before the end of this year to increase the number of local factories to 34. This was said by the Minister of Minerals and Energy Lefoko Moagi this week in Parliament. Moagi highlighted that there has been an increase of companies ...
Improved two-step Brytal process for electropolishing of aluminum
Abstract. Three aluminum alloys (5N, 1100 and 8005) were electropolished with an environmentally friendly Brytal process in order to evaluate the influence of the substrate and the operating parameters in the roughness and reflectivity of the specimens. Electropolishing was implemented in two-step, allowing lower roughness than those …
