Grinding machines work without tools: all they need is the corresponding abrasive medium, such as types of paper and textiles with an abrasive surface. Grinding stones are also used and consist of a pressed and fired abrasive medium – mostly quartz sand. The finer the abrasive medium, the less surface that will be removed per grinding cycle.
Rail grinding machine MPR 4000 E. Designed to make the re-profiling of the rail head after welding. It is equipped with an electric engine, which perfectly operates even when the machine is tilted by 90°. The transmission from the engine to the grinding stone happens thanks to a V-belt with a tensioner.
