Diamond wheel question
« on: January 23, 2016, 01:37:34 PM »
About a month ago I purchased a real heavy 60/80 grit "sintered" diamond wheel from Covington Engineering which has over 1/8" thickness of diamond and I figure at the cost would be a long term user. When I got it it could grind anything fast. Today I started a petrified wood piece and I can hardly see the rock diminish. Its like the wheel just stopped grinding. I don't think I'm pushing too hard. Do these wheels need to be dressed for time to time ? If so with what ? a hard rock ?

Cheers,

Kent

Yes, you do need to dress them when they start slowing down.

just take it off and run it the other way until it does it again, then dress it.

You can dress if VERY fast just by using an old silicon carbide grinding wheel, just a couple swipes is usually all it takes.
