I have 1986 mitsui 205mh grinder in like new condition,recently set machine up with wet grinding system witch works great.Shop is small trying to keep dust down,my question is do I have to worry about trashing the spindle running coolant, read that here on the forum some other member had that problem with same machine.Grinder has stock wheel guard on it.One other question,we like to keep backlash to minimal amounts on machinery my Z axis has 24thou backlash can I adjust that out without taking table off. Machine has no dro on lt.By the way this grinder makes me look like a hero, and l would not make a pimple on a good grinder hands arse.
