Brinell, Vickers and Rockwell Hardness Testing Unit

Description of Brinell, Vickers and Rockwell Hardness Testing Unit:-
The Brinell, Vickers and Rockwell Hardness Testing Unit consists of a hardness testing machine that determines the three main types of hardness (Brinell, Vickers, and Rockwell) in metals, hard alloys, quenched steels, etc. Besides it can also be used to measure the hardness of other materials, such as rigid plastics, bakelite, etc. The most common method used to calculate the hardness of a metal is measuring the indentation strength with the aid of a tool of specific geometry. It consists of measuring the imprint generated when exerting a preset load on the test piece for a certain time. A penetrating ball of a specific diameter is used in the Brinell hardness test to press the surface of the test piece with a specific force. The unit employs balls of 2.5
