    Default Hafco (RF-47) CNC mill and lathe conversions - finished

    I wanted to share the recently completed CNC conversion of a Hafco HM-47 mill and AL-336D lathe, with the hope to inspire others to do the same and provide some encouragement for those working late into the night on their own projects.

    The basic specs of the pre-converted machines can be found at these links:
    Mill: https://www.machineryhouse.com.au/M125D
    Lathe: https://www.machineryhouse.com.au/Centre-Lathes

    A summary of the major components in the build as follows:
    Mill:
    - DMM-Tech servo, Dyn2, 750W servo motors on X, Y, Z axes
    - Noulei C5 grade rolled double nut ballscrews on all axes
    - Marathon Electric 2.5HP spindle motor
    - Teco L510 VFD
    - Mesa 7i76e controller
    - LinuxCNC
    - Z-axis brake (activated when power is shutdown)
    - Festo air management
    - One shot oiler
    - Custom user panel

    Lathe:

    - DMM-Tech servo, Dyn2 servo motors, 400W on X axis, 750W on Z axis
    - Noulei C5 grade rolled double nut ballscrews on all axes
    - Marathon Electric 2.0HP spindle motor
    - Teco L510 VFD
    - Mesa 7i76e controller
    - LinuxCNC
    - Festo air management
    - Spindle speed encoder
    - Custom user panel

    The accuracy achieved on the mill is less than +/- 20 um for X and Y axes and +/- 25 for Z.
    The lathe achieves around +/- 20 um on both axes.

    Excellent Work!

    Is Linux CNC not compatible with the DMM break out board? I just had a 3 axis package quoted through them and would prefer to be running on linux when done.

    I believe the DMM board is compatible with LinuxCNC, but best to confirm with them. I found them to provide excellent customer service. I wanted an Ethernet connection and some of the other functionality that the Mesa 7i76e controllers provided.

    Looks great. Did you convert them to make a particular product?

    Thanks! Yes, I'm building custom electric bikes. Majority of turned parts are either 4140 CrMo or 1020 mild steel. Majority of milled parts are 6061 but some 4140 too.
