Suppose you are using a typical surface grinder, such as a Mitsui, Brown and Sharpe, Okamoto or Harig 6×12 or 6×18. Your grinder has no flood coolant, and you prefer not to use some kind of spray mist coolant; you are going to be dry grinding the steel. This is a typical injection mold making scenario, one that can be very frustrating.
