A Vickers cum Brinell hardness testing machine is a specialized instrument used in laboratories and manufacturing facilities to measure the hardness of materials using both Vickers and Brinell hardness testing methods. This type of machine is capable of testing materials with hardness values ranging from 120 to 150 kg, which indicates the load applied during the testing process. Here are some key features and functionalities of such a machine: Vickers Hardness Testing: The Vickers hardness testing method involves pressing a diamond indenter into the surface of the material under a specified load. The diagonal lengths of the resulting indentation are measured and used to calculate the Vickers hardness value.
