fshegg3 Posted July 7, 2011 Posted July 7, 2011 what is the best way to polish aluminum 6061 T6 alloy to achieve FLAT, PARALLEL surfaces true to .001"? the pieces i need to polish range from 6"x 6" down to 2.5" x 2.5" and are .5" thick. i also need to polish copper 110 on one side only . it has to be flat to .001" also. thank you
Pantaz Posted July 7, 2011 Posted July 7, 2011 One thousandth per foot, per inch, or what? A basic surface milling cutter can meet the tolerance, but you say "polish" -- what surface finish do you require? Much depends on the specifics, but any reasonably competent machine shop can hold tolerances within 0.001".
