Just a little more information--the saw wasn't happy because the blade
was decentered. Crappy blade--lasted two cuts. The replacment was a
different brand and it's cutting much much better. Not great but
better.
I have done some diamond grinding of steels. I agree that high-speed
grinding of steel damages the diamond by getting it hot enough to alloy.
WET grinding at lower speeds, however, works because the diamond is
kept cool by the fluid, so the alloying is at least slowed to a minute
fraction. You lose speed of progress on the cut by slowing down, but
diamond can still remove steel at a steady pace. It just about has to still
be faster than wire EDM and both can accommodate thin kerfs. Abrasive
waterjet can't do really thin kerfs, and will not produce flat faces
of the cut. Not much can beat the cutting rate of waterjet, however.
You can probably do your cuts in 2-5 minutes each, depending on part size!
