I am building a fixture 28 x 18 x 1.5 and wish to know if Haas has a standard "Center to Center" distance for the "T" bolts on the machine table, and if you know numbers for other machines too?
I am trying to make it fit anybody's machine bed.
Now I have two centerline bolts and 6 slots in y, which will cover from + and -Y 3.5" to 7.5"
Here is a picture Thanks in advance guys

Haas has a PDF with all the machine dimensions for each machine right on their website. It includes the table dimensions, T-slot sizes, spacing, etc. It'll take a few minutes to download all the models you're interested in but, that'll answer it for you quickly.

There are several standard sizes, here is a selection of machines with their t-slot spacing:

4.92" or 125mm (VF-1, VF-1YT, VF-2, VF-2YT, VF-2SS, VF-2SSYT, VF-2TR, MINIMILL2, SMINIMILL2)
4.33" or 110mm (MINIMILL, SMINIMILL)
3.15" or 80mm (VF-3, VF-3YT, VF-4, VF-3SS, VF-3SSYT)

The rest of the dimensions can be found here:

--Navigate to the appropriate machine and select dimensions.

(note: Some t-slot dimensions are to center line, not slot to slot)
