sorry for take some time to update pictures. I've done many designing works before on this machine with every part. the pictures show some process of the works under PTC. Once checked the models with software and soft assembling, we can do the real job then.
In my thoughts, I planed to make the machine have around 8"*5"*8" travel range, made of casting iron structure and linear guides, ball screws. with VFD controlled electric spindle unit and stepper drive system. Of course, as an option in future, mill spindle system and servo drive system can be also applied.
So it was designed to a mini precision cnc machine with strong structure. It can handle many material cuttings, from wood, plastic to aluminium, steel pieces. I think some guys may be interested in such small machines. at least it will be a good one for showing building process. I think this thread should be a long term one during my works. I hope you guys can give some comments. thanks.
