www.hardnesstesters.com - Custom Automatic Brinell Tester with depth & optical measurement and automatic surface preparation. With in-line process control, hardness testers can be incorporated into the manufacturing line and the measured data are used to directly control the heat treatment process. Four-cylinder aluminum engine blocks are transported directly from the heat treatment process to a Brinell hardness tester. The blocks are surface prepped and measured according to the ASTM-E-103 Rapid Indentation method. An optical reader could alternatively be used to measure the impressions to conform to the ASTM-E-10 specification.
