Ok do you intend to run a ratio on those screws/motors.? 3000Rpm is too fast for a 16mm diameter screw. Also 180w isn't a lot of power if your planning on a heavy gantry/spindle and wanting to cut steel.!

Good point. I think 1610 with a 2:1 ratio would be better. That would give me 15000mm/min feedrate and keep the RPM of the ballscrew at 1500. 2010 is probably overkill.

I've not seen your design for the router but given the spec of materials and parts, I would consider a Fixed gantry design if Cutting steels or aluminum.

Also, don't be fooled by videos you see on Youtube showing router machines cutting steel, yes they may do it for a video or two, but for how long and at what cost in terms of tool life and stress on the machine.? . . They never show or tell you this.!

The machine will have to be made with moving gantry because I require a work area of minimun 1000x800mm for woodworking. The steel machining I am talking about would be machining parts for a new machine in steel in the far future, that would be designed for cutting steel only. This one would then be with fixed Z-axis. Also for the video, here is some german guy running 1605 with those same servomotor, cutting aluminium: https://m.youtube.com/watch?v=xyVr35pgx7s

Given the above then for a Wood/Aluminium machine then yes easily.! . . . Steel, forget Aluminium profile of any size.

I will consider 80x160 since the steel machining would be limited to a minimum (see my comment above). Thanks for your detailed answer!

Yes 2010 would be over kill and would actually lower performance or should say stress the motors more because your having to deal with the extra inertia of larger screw and ballnut.

Cutting aluminium isn't a problem with 1605 or 180W servos, esp using adaptive tool paths like they are using as the feed rates are much lower and forces are not too high. However Steel is a different mattter and the forces are much higher.
My comment about the motor power being on the low side and the speed is mainly aimed at higher feed rates when cutting soft materials which require high feed rates, also at rapid speeds when bringing a heavy gantry to a stop or fast directional changes. This is where low power motors struggle, with steppers you'd lose steps but with a servo you'll get high following errors and potential fault trips.

Experience as shown me that building a moving Gantry machine that can cut everything including steels and cut them correctly without destroying itself is very difficult to do and profile section isn't strong enough for a machine like this. You need much stronger materials like steel or Epoxy granite and ideally a fixed gantry.
In your case it will serve your needs for very occasional steel work but don't expect to take heavy cuts or have great finish.
