Grinding of tribomet

I REQUIRE DETAILS ON THE GRINDING OF TRIBOMET. i.e., WHAT WHEEL IS SUITABLE FOR GOOD STOCK REMOVAL , WHILE MAINTAINING A SURFACE FINISH OF 0.4 - 0,6 CLA AND PREVENTING SURFACE CRACKING.

You have contradictory info here. One your talking about a very smooth finish and two heavy (?) stock removal? If you need to maintain that finish, I'd stay with a cotton wheel; however, if you need a lot of material removal and maintain a relatively smooth finish, I'd go to a non-woven wheel.

Tribomet is a proprietary cobalt-chromium carbide plating used in Rolls Royce engines. Because of the embeded carbide particles, you will not get a very fine finish. I do not know what your surface finish language is as it is not a common one in the usa. Use lots of cutting fluid. The part gets quite warm and there is significant dimensional change on large parts. It does grind quite nicely. We trued the wheel after every couple of passes and ended with two spark out passes. We only took half thou passes, like you should grind chrome.
