Dressing diamond cup wheels

[cncorbust]

I posted this question just a few minutes ago but I think I posted in the wrong place so at the risk of cluttering up the group I will repost here.

I have a Norton 3.5" diamond cup wheel. It is used on a Taylor Hobson engraving cutter grinder. The surface has become uneven, there is a "waffling" or undulation of around 0.001 to 0.003". The uneven surface now sets up a vibration in small diameter cutters and seems to be making the uneveness progressively worse. The wheel runs true and does not cause noticeable vibration. There appears to be at least 1/16" of impregnated material still on the wheel.

Is there an economic way to correct this problem?

try getting a silicon carbide (green) wheel and use it to remove forrens (SP*) from your wheel. use it with your steady hand!!

I use a Newman wheel dresser, Model number 1. Tenafly, NJ 07510 (or 07570 ?)

This unit will make your ginding wheel run perfectly true. You may need to hit it with a white drssing stick after trueing to expose more diamond surface.

IIRC, the unit cost about $50. I'm sure MSC, J&L etc. carry them.

P.S. I have heard that you can clamp soft steel down to t atable and feed into your wheel. This will burn the diamond right off and true the wheel (diamond is pure carbon) I never tried this myself.
