Metallurgical cutting machine, as the name implies, is the cutting equipment used in the preparation of sample preparation in metallurgical analysis. Due to the different requirements of metallurgraphic sample preparation, there are certain requirements for the feed direction, clamping direction, feed speed and cooling mode when cutting samples, so there are various forms of cutting machines designed for this preparation process.The mechanical properties of the sample are not only related to its chemical composition, but also to its metallurgical structure. Metallurgical examination is an indispensable means to control and evaluate the quality of products. It is also an important method to improve the internal quality of materials and new technology in scientific research.
