Sturdy and Fast all Steel CNC , my first build

[Boyan Silyavski]

No body says nothing, may be the thread is not so interesting as it seems to me or i am doing it right

Soon will make it more interesting with pictures of the process. Now everything is ordered including the steel profile. Will have to pick it tomorrow and solder it this weekend.

At the end i used only 100x100x3mm steel box for everything. The 4mm seemed very heavy and overkill for the 0.8kw spindle .
I still have doubts for the threads on the rails so most possibly will solder additional plates for the threads of the rails. Anyways they will be covered by epoxy.


Here is the final design , its lighter and stronger than the 60x60x4 and also another point is that less cutting and soldering is needed.

400x1000 x Z 170/up to 200/ working area, gantry ~35-40kg with everything mounted, profile structure and gantry with plates = ~ 100kg
