Selection of suitable milling machine for CNC conversion

[Edward]

I converted my Sieg 2.7 to CNC and I am happy with it.

What can I say, it's Chinese, so you will need to adjust and improve a couple of things here and there, but nothing major, or difficult. I had to grind a bit of the underside of the table to be able to fit the ballscrew, but other than that it was a straight forward conversion. I read this forum extensively to get me acquainted with what drives to get, steppers, etc. and eventually I made my own toroidal PSU as per instructions in this helpful forum.

Don't expect super fast speeds or large widths of cut, it's a small mill after all, but if you are sensible, you can have a nice machine that you will enjoy.
The main negative is that the head is fixed, i'e, it doen't swivel or tilt forward or backward, so for tramming you need to shim the base of the column which requires a little more patience, but quite doable. If you were to get this mill, get the version with the longer table.

I've only just finished my AMAT25. Hopefully start testing it out this week, time permitting.

I similarly did the SX2.7 - long table version. One word of warning the SX range have the DC brushless motor which causes a problem getting the spindle under NC control - so the S2.7 might be easier. Nice machine once you get it under stepper control.

Most of the mini bench mills have common ancestry within the Chinese foundries... just different paint jobs.
