Slant bed CNC lathe from scratch
So it begins...
Im nearing the completion of my cnc router build from scratch from lasercut steel, waterjetcut aluminium, linear bearings and a lot of homemade parts.
I promised myself that i wouldn't undertake any new major projects until it is completly finished, but that doesnt hold me back from designing now.
Here is what we are aiming for:
Slant bed - to allow for cooleant drainage etc. and because it looks cool:)
Complete enclosed - To allow for heavy flood cooling and to make it look more "pro"
125mm chuck - with possibility to add a 160mm later on
400mm of z travel - properly no tailstock anyway
150-200mm of x travel - Sufficient for that size chuck i guess
Tool turret with 8 positions, room for 4 cutting tools and 4 drills - Will properly be a project in itself later on
And the way to get there:
220Ncm stepper on z - I may change the design to accommodate a 650Ncm
180Ncm stepper on x - Maybe 220Ncm as well
Double nut or zero backlash ballscrews on both axis
Build from scratch of 20mm steel plates - Giving it a weight of +140kg, should provide a very ridig construction
Hiwin linear profiles, 20mm square type for z
20mm flat linear profiles for x - Bought of ebay some time ago
Now for som design pictures. I really hope to get som inputs on the design before i go on with the buildning:

Based on my experience from building the router, im going to build it out for MDF to begin with, there is just to many unknown factors you dont catch in the designing process, hence the idea of doing prototypes.
Thats the beginning, all kinds of input and questions are welcome
