Choosing a stepper motor

[Daffy]

I'm looking for a stepper capable of driving a X,Y,Z axes for a table that could be like 100cm z-axis, 50cm x-axis, and what ever is necessary on the z-axis.
Would the one at the link be suitable?
It is 1.86Nm - 263Oz.
I could use 2 for the z-axis, and one each on the other axis.
I want my table to be able to handle both a dremel-like machine for aluminium and such, and a bigger wood-router-machine for wood-work..

Will this stepper handle the up and down direction (y-axis) ?

It is rated 4volts. Using a PWM controller board, how do I find the maximum voltage to feed this steppers..?

Hi Daffy,

Unfortunately it is impossible to recommend a suitable stepper motor without a lot more information.

Gantry or moving table?

Weight of gantry or table?

Ballscrews, leadscrews or threaded rod and pitch?

What type of linear slides?

Required cutting speeds and rapids?

I agree with John in that there are a lot of variables to take into concideration.
It is more likely you would need 2 steppers on your x axis than the Z.
It should be possible to design a machine with these steppers but it depends on how fast you want to go and your budget for things such as ball screws.
And I would not look at a Dremel on a large machine. I made mounts for both a router and Dremel for my first machine and only used the Dremel once.
