Re: surface grinding copper
I am not done with by homemade block yet, but I did start finishing the block that I am putting between the TEC and waterblock and this is the first time I have made something that actually has to be really flat. Maybe the mill I used kinda sucks but the fly cutter didnt leave it totally flat I found out when hand lapping. I dont know about grinding it but generally with copoer you need a very high cutting speed. There is a grinding machine at our machine shop but I dont really know how to use it.
