Hi Wellcome. Those pictures seem to be of two different machines. It sounds like the spindle axis is probably trapezoidal rather than
ballscrew. The table and gantry do not look to be very strong or well braced, but it does seem to use profiled rails. I suspect it will be fine for lighter/softer materials if that is what you intend to use it for, but wonder how it well it will cope with with multi-users. these comments are just my own thoughts, and I am sure that some more experienced members will soon comment. Good luck with whatever you decide. G.
