Automatic Hardness Testers in The Motor Industry 710629

This paper describes the way in which a basic Rockwell hardness tester of special design (a so-called Emcotest unit) can be used to achieve various stages of automation, ranging from simple multipurpose automatic standard models to fully automatic hardness test stations integrated with long-run production lines. The scope of this article has been intentionally restricted to the field of automotive engineering, although the instrument is applicable to other branches of production engineering as well as to manually operated stationary or portable appliances. The latter applications are covered in the literature listed in References. 2
