Rockwell Hardness Testing Machine

Rockwell Hardness Testing Machine Points : Rockwell Hardness Machine, Definition, Rockwell Hardness Testing Machine The Rockwell hardness machine simplifies the process of Brinell testing, because in this machine, it is not necessary to take microscope readings of the indentation and the scale of the dial gives a direct reading of hardness. There are two scales on the dial, B marked in red and C in back. Each is graduated with a hundred divisions. Zero of C scale is opposite to figure 30 on B scale, so that there is a difference of 30 hardness numbers between the two scales at any point.
