I have been working my 220 DMT diamond plate pretty hard lately.
Like grinding down a bolster on a Wustoff for a pal and working out dents and divits.
Is it possible to wear down a plate over time?
Has anyone had to replace one, in the past?

p.s. I did try searching any info about this on the forum. Either I am a crappy searcher or...well I didn't try too hard.

Thanks,

Everything will wear out given enough use and diamond plates are no exception. The biggest killer of the plate is pressure. Diamonds don't need to be forced like other stones to work, they cut on contact and you must be careful to control penetration depth of the abrasive to keep it working correctly.

If you were using it like a regular stone then it's probably been damaged.

Thanks for the info.
Does that mean it will cut as quickly with little pressure as it did when I was pressing into it heavily?

It's a really short way to put it but, yes :)

For heavier work, don't use the 220 Either use the XXC DMT or Atoma 140. For even heavier work I use a 60 grit diamond plate. Or a 24 grit stone. Or a belt grinder with a 3 hp motor and 24 grit belt when I really want to see metal disappear.

That's great stuff guys. Right now all I have is the 220 as my lowest grit stone. I am slowly building my stock of stones.
I sure would like to own/have access to a belt grinder, but until then, I guess I would like to get good at using stones and plates for all I can.

I sure feel lucky to have both of you, Jason and Ken for wisdom and expertise. I am sure I speak for the whole group of us.
