Good Morning All,
A couple of weeks ago I switched from "white wheels" to CBN wheels (on the grinder). Cool running, effective grind, no wheel dressing, and no shrinking wheel diameter. All good things, right? However, my experience has been somewhat mixed, and often frustrating. Wheras I seem to be doing well enough with gouges (using jig), my results with skews have been quite inconsistant (use platform). I'm one of those who has been depending on the "spark edge" as a signal to stop grinding. Recalling Alan Lacer's comments on the lack of such a defined spark when using CBN wheels, it has occurred to me that I"m not really sure what to look for, in terms of edge readyness if you will, when using these wheels. Yes, my skews are getting long and "pointy". It may well be that the age related MD has brought me to a new place. In any event, I was wondering what your experience has been. Is there a learning curve? Are there specific things I can look for? (Other than the skew simply does not perform well.) I'll very much look forward to your thoughts and comments.
Best,
Herb Flower
