Hello Thaddeus, The machine doesn't have an independent wheel dresser so I plan to mount the dresser on the right hand corner of the tailstock way. It has enough room for this. Actually we're doing what you suggest with the grinder that we have driven by LCNC. But this one uses a master to shape the lobes to be machined, so we only need to know the diameter of the part being ground. The problem I see with only touching the wheel in one point, is that I need an exact reference of the center of rotation of the wheel and I don't know if in practice that's possible for me. I don't understand the part about knowing the event of a diamond being detached from the dressing tool. Please correct me if I don't understand you well.
