Lapping Overkill?

post #1 of 9
Thread Starter 
I'm about to lap my processor and maybe my Zalman depending on the flatness test I'm going to do (because my Zalman came with a mirror finish, whether its flat or not, I don't know)...just want to know what the highest grit sandpaper I should use. I know to start around 400 and work my way up...but how far up? My little brother does body work on cars and said he can get me up to 6,000 grit sandpaper, should I take it that high or is it just overkill at that point? Thanks!

1500 will actually get you a mirror finish

anything after 1000 i feel is for looks more than function but your only going to do it once so why not go for 1500+

if you have access to this kinda stuff most people dont

use a CNC milling system and you can make CPU's and HS's flat with less than 1000th of an inch difference

it will be about the same surface look as if you used 5000grit sand paper
post #7 of 9
ye, i got one of those CNC machines in my back pocket.... just let me pull that out, but if the HS/IHS is concave to more then a 1000th of an inch, then your statement is a lie... that is all

I generally only lap to 600-800 grit, not much point in going further.
