Hello all,
A friend and I have Benchmaster MV-1 vertical mills, these are bench top units originally made in California about 50+ years ago, and got to discussing 'how flat' should the table be.
I had mine surface-ground at a facility that does highly critical work for the aerospace industry, often to ridiculous specs, and am comfortable my table is now as good as it ever was, perhaps better.
Unfortunately there is nothing available I can use as a reference as to what it should be. A question posted to the Benchmaster forum elicited some interesting philosophical responses, but (guess what?) no hard facts.
So I turn to you gentle people - does anyone know what the 'standard' spec would be for mill table flatness, being mindful this is a relatively small table (6 X 18), construction all CI and quite well made here in the US of A.
Even specifications on other mills would be of interest, at least to know what one can expect to find.
Thanks in advance,
Mike
