grinding wheel Identifcation? - sasquatch - 12-19-2012
Back a bit ago i bought a bunch of stuff out of a deceased friends shop.
I have a new unopened case of 6 of these grinding wheels marked :
Norton -G103
Then-39c601-K8VK 6in x 3in x 32mm
Anyone know what these are for? Surface grinder???
Tried searching Norton couldn't find that # Thanks.

Those would more likely be for a small centerless or cylindrical grinder.
The G103 doesn't seem to mean anything of importance, probably just a production code of sorts. Norton made and continues to make a LOT of non-stocked standard wheels for all sorts of special applications.
In the "39C601-K8VK" the "39C" suggests it the 39C Crystalon, a silicon carbide abrasive good for carbide, tunsten and other dense materials. Is it a dark gray or green wheel?
The "601" part confuses me because that's usually a two-digit number or a zero in the third position if a 3-digit extra fine grit. It's grit size, and either it's a 60 grit or a super-fine 600. I tend to think it's a variation of 60 grit.
The "K "means it's a fairly hard bond, on the upper part of that scale for vitrified wheels.
The "8" means it's a free-cutting, relatively open wheel. More air spaces between the abrasive grains and bond gets an 8 to 12 (higher is more open), less air space and higher density gets a lower number.
The size is unusual. Being 6" in diameter but 3" wide is what has me thinking small centerless grinder. The 32mm bore lends me to think it's for a European made machine. You may not ever find the application, so just take some good photos and put them out there on eBay.

Thanks for that info, and yes the wheels are grey, somewhat coarse, i rechecked the number and yes it is 601.
Trying to decide what application i could use these wheels for, but the 3in width is puzzling.
I also got another box full of smaller wheels, all around 2-3in dia., some cup style with different bore sizes, all new also, in white, grey and pink.
This guy was a real packrat, have no idea why he had all these wheels, heck there were wheels there up to 20 in. in dia x 2 in. wide.

Chances are he worked for either a grinding wheel maker or a reseller. Probably the latter, though the outside chance that a distributor just gifted him a lot of old stock.
The 20" wheels are cylindrical grinder wheels. There is a bigger market for those.

Could the 20" x 2" wheels be for crankshaft grinding?
