Another thing I should have mentioned is that stiffness plays an
important role in resisting constant cutting forces, as well as the
cyclic forces which cause vibration. For example, if the table of your
mill distorts due to cutting forces, you get an inaccurate component.

If vibration is a big issue for you, I'd suggest looking out for a
proper 1 ton saw. Ultimately this is a much better solution to the problem.

Best wishes,
