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.. :) )
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! :)
