HQ800 Harbor Freight 3in1 Mill Lathe CNC Mach 3 Conversion.
First attempt at a video. This 3 in 1 came from Wholesale Tool but is the same as the Harbor Freight unit. X & Y are Gecko driven servos, Z is Gecko driven stepper (which replaced 2nd burnt out Z servo motor!)

  • Is the lathe operation also CNC controlled? I need a machine that could mill onto a round piece of graphite mounted into the lathe, then turn the piece slightly and mill it again.

  • The lathe spindle is not controlled.

  • Great Job I just bought a new one for $1100 w 20% coupon. How much did your conversion parts cost?

  • Maybe $500 plus junk box parts, such as the big servo motor that I already had.

  • How do you like the harbor freight lathe?

  • It works pretty well. When milling I often have to raise the work especially when using collets. The cross slide screw I replaced with a ballscrew. It would not replace a Bridgeport but good for general purpose use.

  • Great Job!

  • i see the blocks used to raise your workpiece and the clamps that are holding the work to the blocks but what is holding the blocks down?

  • I have bench mill that I would LOVE to be able to do this to. I'm just way behind the learning curve.

  • What are the distance between centers of this lathe?

  • What type of stepper motors did you use? I have a Smithy CB1220xl 3 in 1. And I'd really love to convert it into CNC, but I dont know where to start.

  • Sweet! I want to do this with my Bridgeport clone (a little bigger unit than the Harbor Freight)
