Hello everyone!

My name is Lennert, im from Belgium and i'm converting a HBM 45 PROFI to CNC.
I'm studying mechanical engineering and am currently in the final year of my master.

The goal is to convert the machine with as little modifications as possible. It will not be the cleanest conversion, but it will functionall.

I started with the conversion of the Y-axis:
Due to the square shape of the ballnut holder i lose a few centimeters of travel in the Y direction, but once the cnc mill is running i can round over the edges.
The nut holder was made on the lathe with a 4 jaw chuck.

The stepper and bearing block are mounted on a 8mm thick steel bracket that was TIG welded:

Once the Y-axis was complete I started with the X-axis:
The ballnut holder was made on the late with a 4 jaw chuck and the side chamfers were made using a hacksaw and file since my mill is in pieces.

The bearing block and stepper are again mounted on an 8mm thick steel bracket:

My TIG welding isn't the best but certainly enough for the application here.

The steppers are NEMA34 8.5Nm Dual shaft and the ballscrews are SFU2005.
