    Re: 7 Axis Swiss Mill-Turn (DIY)

    Have you thought about a pre-owned machine? We've bought a few from a place called resell cnc. They are honest, reasonably priced, and can arrange to have a third party service tech inspect the...
  3. Re: Setting Lathe Tool Position - Not Cutting in the center - Help.

    Glad to hear you got it sorted out.
    I realized it was an old post about halfway through typing it. To late to turn back then. :)
  4. Re: Setting Lathe Tool Position - Not Cutting in the center - Help.

    There are a few reasons why the tool would be off center. Turret base alignment, turret rotation alignment, spindle alignment, or the wrong size tool/insert/seat.

    Pretty Cool

    Very cool Hoss,
    I'm interested in how you programed this with your CAM system. Did you interpolate using G18? or did you trick the machine? by switching Z----->Y and Y----->Z?

    Synchronous Belt Ratings

    Hey Hoss,
    I came across this in the machinery's Handbook a while ago while building my mill. I found it very useful in determining and adequate sized belt. Hope it helps.

    Way to slow?

    I think you may be going way to slow (rpm)
