Tungsten surface finish

[Bendaman]

I use a bench grinder to do my tungsten work, my question is:
What grit diamond wheel would give a RA20 final surface finish. The reason
I'm asking is I have a Recent issue of the Enco Catalog and they list
Diamond Plated grinding wheels in there 100, 150 and 220 grit. Would
any of these be suitable for tungsten use?

I've reviewed past posts and know diamond wheels are being used, just
wondering what works best?

Thanks for any advice!

be aware that some of those wheels are nut suitable for sharpening tungsten. Someone else might be able to help you better though. Try maybe posting a link to the wheel. Ive been at this for several years and have only used a fine and coarse(for roughing those 5/32 tungstens) aluminum oxide wheels on a 1 hp baldor grinder(you know the type with one wheel on each side).

check a real 1

the tung grinders use 300 and 600 grit but not shoure if you need that smoth although you are trying to get it right, so i gess get the highest grit you can.
wondering how much $$ they want for the wheel ?

The Enco book lists them at $94 for 6" dia 220grit.
I think tomorrow I am going to call diamond ground, I did not see a
listing for just wheels on their web site. I was just having a difficult
time finding something local. On the one side of my grinder I am running
a fine grit Alum. oxide wheel, Just looking for something on the other
side to do a good finish???

i would think the 220 would do it but for another $95.00 you could get a real tung. grinder (with an extra wheel right now on the arc-vone site i think)
i dont know how long the tung grinder wheels last though.
is the 6" wheel going to last longer ?

Check out the Piranha II. It puts a 20 RA finish on the tungsten and is made to sharpen .040"-3/32". This is all you will ever need for the Dynasty 200 and 300.

Blown S 10,
What wheels are you using on your grinder. I,m using 100grit Alum oxide
for roughing in point, but was wondering what work best for final finish?
I'm using just a standard 6 inch bench grinder also.

Thank for any info.

i don't know what i'm going to get yet. gotta stop at home depot soon.

I also use the 100 grit for rough and 220 for final with no issues. For real fine low amp Tig I will rough and finish with chem sharp.
