My next project, not even started yet.. is to build a surface grinder that will use 8" x 1" x 1" wheels. I have seen a lot of these wheels.. and wondered how practical one would be if it's max speed was 2,865 RPM.
Motors usually turn at ~1700 RPM. There's ~1115 RPM difference. I would like at least 3 different ranges of speed. So that being said thats ~371 RPM per step.
Is 2,865 a good RPM # for mild steel, or for surface grinding in general?
What else should I have in my design.. I'm going to use a design quite similar to the one in HSM. Should I build a CNC suface grinder? Toolpost grinder?
