The Rockwell brothers were metallurgists working in a Connecticut ball bearing factory back in the early 1900s. They recognized the need for accurately and quickly testing metal strength in bearing races. They also required a clear method for reporting strength test results. . Rockwell hardness testing equipment is quite straightforward. It .
Stanley P. Rockwell invented the Rockwell hardness test. As a metallurgist for a large ball bearing company, he wanted a fast, nondestructive way to determine if the heat treatment process they were doing on the bearing races was successful. The only hardness tests he had available at the time were Vickers, Brinell and Scleroscope. T he Rockwell Hardness Tester was designed in 1919 by Stanley P. Rockwell. He was a metallurgist in a New England ball bearing manufacturing plant. Until this time industry lacked a good method for measuring the hardness of ball bearing races and other hardened steel parts. Mr. Rockwell studied the problem and through experimentation for accurately .A test inspired by Robert Bastow when he commented on anvilfire by saying, "You could bounce a 1" steel ball off the monitor!". Obtain a steel ball bearing ball (1/2" (13mm) to 1"(25mm)) in diameter. Drop (DO NOT THROW) the ball 10" onto the face of the anvil. On a really hard anvil the ball will bounce about 75-90% of the distance dropped.
