The Rockwell hardness testing method

The hardness test method was named after its developers, Stanley P. Rockwell and Hugh M. Rockwell, who worked as metallurgists at Departure Manufacturing Company from 1914, looking for a simple and fast method for testing the hardness of bearing rings. At the beginning of the 20th century there were various methods for determining the hardness

For single-spindle machines, bypassing the need to index the turret can dramatically increase hourly part production rates. On long-running jobs it is common to use a roughing tool on a different slide or turret station to remove the bulk of the material to reduce wear on the form tool. There are different types of form tools. Insert form tools are the most common for short- to medium-range
