Thread: Grinding belts

So I went shopping for grinding belts. I found aluminum oxide, ceramic, zirconium, and silicone carbide. My question is are some better for rough grinding, pre hardening and others better for hardened steel?

I am not an expert in abrasives, but here is a web site that might shed some light on your question.

It sounds like Zirconium oxide (Zirconia) might be the best abrasive for rough grinding and significant material removal, but other abrasives might be better for final polishing.

Ceramic and zirconium last much longer than alox or sic. Especially for lower grits where you want to remove a lot of material.

I haven't tried the all by any means, but prefer the orange Blaze ceramic, at least up to 120 grit. After that I use silicon carbide.

The ceramics cost more, but last way, way longer, run smoother and cut easier with less heat. I get most of my belts from Trugrit.

Whatcha grinding with, Rez? Was there a grinder made in Texas?

No. No grinder built in Texas, but there is a company that makes them right here in B.C. Nexus Grinder. I ordered one. I was going to build on but I think this is more simple. I have no idea what I will be grinding though. Seems I’m about to get really busy.

If your like most people you will find a lot of uses for that grinder.

I just looked at the grinder website

It looks like a well made grinder with some good features. I liked the size of the work rest a lot. The flat platen can be adjusted in a number of ways and you can have different tool arms.
And the price is very good.

Those are Canadian dollars too! I think it is a very good value and like most I try to support those closest to home when I can. After a few emails I was pretty convinced it made the most sense.

so in Canadian dollars what are you looking at for the grinder, arms, platens, and a motor with variable speed? if i remember correctr, Daves Bader is around 2500, not sure about the extra parts, but it has the controller and motor, and its a pretty slick outfit, thats why ill have to have 2, unless this one is a much better deal then ill get 3!
