Thread: Atoma lapping plate

I use a 6 micron (4k equivalent ) for chips or wavy bevels on TIs or other hard steels. It doesn't dish and it gets me through the chips plenty fast. Then back to the chosera 1k and up. This one doesn't leave any scratches that the 1k can't easily remove.

+1 on that for me too. With the Chosera 1k I don't need anything else. Bill looking forward to hear how the 600 works for you.

You find a 6 micron plate cuts faster than a 14 micron stone ? Seems a redundant step to me.

Actually wouldn't surprise me, diamonds cut more aggressively than AlO, especially on hard steels.
Sometimes even a finer diamond plate can cut faster than a course, it's like the courser one can't grip the steel, it just skips over with a few scratches left behind.

AlO is more gentle in removing steel.

Using abrasives is a science but it sure is strange sometimes!

It seems that it does cut faster. And no worry about dishing(not that choseras dish easily either).

Yes , Al Ox is a slower cutter but some stones also contain Si C which puts them not too far behind diamonds in speed but without the depth of scratches. It's interesting that even some Jnats can cut out of all proportion to their fineness. Yet another YMMV .

Just an update. The six hundred arrived a while ago and I've done a few stones with it. It laps well, no question. I find the scratch marks quite deep, so the 1000 would probably be better on stones over one thousand. But it works, and it's an excellent plate.

I can say that I used my Atoma 1200 on razors, no problem at all. Some swedish and sheffield razors are so hard that if i should set a bevel with a stone it would take ages..

If you just hold the edge at a 90 degree angle to the atoma you will get a very nice scratch pattern. As soon as you turn the edge a little the scratch pattern will be uneven. Thatis because the layout of the diamonds on the atoma.
