Abstract:
1. A testing machine, comprising: a plurality of test devices for performing various hardness tests selected from the group consisting of Rockwell hardness test, Vickers hardness test, Brinell hardness test, micro-hardness test, and tension-compression test, wherein each of said test devices is an individual unit that each of said test devices comprises its own force sensor and its own data processing circuit; and a stand comprising means for power generation, a slide device driven to slide by said power generation means, and a control system operatively linked to said test device when said test device is coupled at said slide device for controlling a force applied on said test specimen, wherein said test devices are replaceably and detachably coupled at said slide device to perform said corresponding hardness tests, such that by selectively switching test devices are selectively switched from one to another, said testing machine forms a universal testing apparatus for performing said different hardness test of a test specimen.
