Optical Brinell Hardness Testing Machine
FMI has developed Brinell Hardness Testing Machine with optical device. Basic machine design and operation is similar to TKB-3000, with built in optical device with 14X magnification provided in front to project diameter of ball impression on glass screen with a micrometer measuring system with 0.01 mm least count. In this machine the indentor swivels and projects diameter of ball impression immediately after unloading operation which avoids additional time for measurement of ball impression. This is a production testing machine. This is suitable for foundry, forging shops, heat treatment shops, engineering institutions etc.
