The spindle head is made of lasered plates and holds the spindle cartridge (old version of the spindle flansh in the picture below)
Assembled spindel head (old version of the water cooling):
Spindle belt drive:
Self engineered pneumatic cylinder for the draw bar:
All assembled and painted (cylinder fixture is temporary..):
A belt pulley was adapted to the 2.2 kW Spindle motor (China Spindle - used as motor) to drive the spindle cartridge
Components for the X-Y-table were machined on the lathe
Side stiffeners for the z column (lasered plates)
Assembled Z-axis, side stiffeners and X-Y-table
The back of the Z-Axis was casted in UPH concrete
At this point i decided to go full in and build up the overall machine from scratch. I designed it in CAD and continued with the Spindle cartridge, since it is the most difficult part.
Turning the cartridge
Grinding the cartridge
Turning the spindle shaft
Machining the draw bar
Finished draw bar (hardend to about 54 HRC - C45k)
Spindle watercooling mandrel
Finished spindle cartridge (after some iterations.. :) )
Assembled in the spindle holder
Without the actual intention to build this machine at the beginning, I started of with random cut offs from ebay. (Just planed to improve my former CNC milling machine)
First I used the bench top lathe (that was borrowed to me for a different project :) ) to get the dimensions of the parts on point
First finished parts...
Critical dimensions (bearing seats) were machined on the bench top lathe

What was the cost of this, if you don't mind me asking…this has great build quality and in my opinion it is worth as much as the commercial products! Great work and have fun making! :)
Are you sure? yes | no
Thank you! The overall cost, excluding the servo system, was around 1.5k Euro. The servos doubled that :)
Great project, I admire the hight quality of the results. It motivates me to build similar things.
Thank you - I appreciate it! Glad to hear this, that's the reason why I share it :)
Phenomenal build quality! I'd love to see a build log for this one.
Thank you! Good point, I will add a few pictures to the log :)
