grinding / machining of CuNiIn coatings

Posted by t faucette (205.188.117.9) on 01:26:45 24/04/06

we are attempting to grind CuNiIn coating applied to both sides of a flat surface approx 4" wide x 40 " x 1.25 " thick, alloy steel, @ approx .010 " thick coating.
One subcontract source attempted to use diamond wheelon a surfce grinder but experienced vibration due to set up - couldn't finish job; another attempted to use Al oxide cup wheels in a milling m/c set up -cutting full wheel width x .0001 " doc, soluble oil coolant - experienced delamination and blistering of coatings - cannot find recommendations re grinding procsses - can anyone advise??
