Is there any difference between the Seig Mills sold under many names?
You guys are a fantastic well of information. Thank you
How do you like the universal mill seems limited on the Z axis . Probably ok for milling but not good for drilling.

That is interesting in that I didn't realize the nose of the spindle took lathe chucks.I love the little SU1. Small and sturdy, weighing in at about 200lb for such a small machine; machines mild steel with ease; cuts aluminum or copper like butter.
It mills, slits, bores, and turns. Yes it takes a 80mm or 100mm lathe chuck (same as on C2/C3) with a MT3 shank, and essentially functions as an ultra-sturdy short-way lathe with a very large array of tooling laid out on the mill table (CNC possibility is just endless).
Thanks for the pics. Whomever made that original machine did a very nice job!The odd U1 started out as a home-grown-project by an individual on a watchmaker forum. Here is the initial appearance of the fore-runner of the U1:
I hope the guy that did the original concept got something for it. Not that the machine is unique other than size, still the prototype certainly inspired Sieg.And the original thread from 2005 for additional historial refrence :
SIEG then took it and made it into the U1/SU1.
This is what bothers me about the machine, it is very compact in axis travels and clearances. At least in the form shown on the Grizzley site it is. That being said a larger version would be very appealing for many home shop machinist.Here's my SU1 cutting 2024 aluminum alloy with a 16mm endmill:
Regarding the oft-noted concern with Z-axis space, simply opt for collets for tool-holding; then it is very comfortable with rotary tables, angle vices (is that the right term?), etc, all but for the universal dividing head.
So ... SU1 for its unique profile and versatility, compactness, sturdiness, and brushless low-end torque. I think it's worthy of a CNC retrofit.
were can I get one of those
... We can only hope that it is successful and inspires Sieg to build a larger variant...
I guess the universals really is a breed of its own; a cross between a mill and a lathe...
