Birth of the Tool Post Grinder
In 1920, the newly found Dumore Corporation needed a
low cost tool to grind bearing seats on armature and
spindle shafts. Forced to improvise, Dumore engineers mounted a hand grinder on a compound lathe, and the
“tool post grinder” was born. The grinding job could now
be done on an existing machine using a tool that was a
fraction of the cost of a standard grinder – a tradition
that continues today!
