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.
