I couldnt find anything on the maker listed, but are you sure thats a mill?
To me it looks more like a precision drill press. If so, milling with it in material much harder than plastic likely will destroy the bearings, similar to milling with a jig bore.Last edited by justanengineer; 12-31-2011, 01:52 PM."I am, and ever will be, a white-socks, pocket-protector, nerdy engineer -- born under the second law of thermodynamics, steeped in the steam tables, in love with free-body diagrams, transformed by Laplace, and propelled by compressible flow."

Fred - The rigidity/size of the iron isnt what is important, its the bearings' load rating that is important. Those have bearings rated for direct axial loading only, not side loading, because they are intended for drilling/boring operations. Many mistakenly think that they can "get away" with milling using something like this, but in reality all they are doing is destroying the bearings, or at the very least wearing them to the point of losing accuracy.
I once bought a Linley jig bore because the bearings sounded smooth and quiet, despite the PO admitting that he used it for milling aluminum and occasionally steel. Unfortunately, those same quiet bearings prevented the machine from boring a straight hole, being useful for most drilling ops, and as for milling it chattered like crazy. What I effectively bought was scrap iron, but it did look and sound good.Last edited by justanengineer; 12-31-2011, 03:08 PM."I am, and ever will be, a white-socks, pocket-protector, nerdy engineer -- born under the second law of thermodynamics, steeped in the steam tables, in love with free-body diagrams, transformed by Laplace, and propelled by compressible flow."
