    That didn't occur to me. I've used peening on sheet metal. Would it work on 10mm thick unhardened O2 / 1.2842 / 90MnCrV8?

    The move across wheel width and downfeed might have been faster, I didn't think of that here. Let's see:

    At two microns per downfeed and 350 microns off I need 175 downfeeds. At 12 traverses per...

  4. Surface grinding technique: roughing corner/finishing corner

    A few years ago, when I got my first surface grinder, Buck suggested a technique that I now use a lot.

    Case in point: I cut a 50 x 400mm strip of 1.2842 (90MnCrV8 or AISI O2 tool steel) from a 10...

    Of course Richard and the others are right: you should mill material off of the carriage to make space for the Turcite/Rulon/Moglice. It would take forever to grind off that much, and you are much...

    Grinding the bed will lower the carriage, so it won't line up properly with the lead screw and the power shafts. If the carriage needs to also be ground, then that lowers it even more. So the usual...

    "Needle flutter" in the Talyvels can be due to insufficient damping of the pendulum. This is easy to adjust and I thought that I would document the procedure here.

    The damping comes from a small...
