Tungsten grinding question.

Postby Panchdara » Mon Jan 01, 2018 10:09 am

I can completely appreciate the solid advice on grinding a tungsten electrode. That advice being to use a dedicated grind wheel for the sole purpose of tungsten grinding. My question is in respect of that dedicated grind wheel.

Using different types of electrodes, ceriated, lantanated, thoriated ... can one use the same grind wheel for all types, or should one use a separate wheel for each individual type of electrode?

Regards

The same wheel for any tungsten is fine. Diamond wheels are best, but most expensive. The green silicon carbide is a great choice too, but they are soft and will groove up if you don’t rotate your tungsten across the surface (chuck it up in a drill, spin slowly, and slide across the width of the wheel while it’s spinning). I follow up with a red scotchbrite pad to polish it afterwards.

Thanks CJ. Noted: diamond wheel and scotchbrite. I have 2 small bench grinders and will put 2 diamond wheels (120 and 600) on one and dedicate it for the purpose. These wheels from eBay and less than $10 for the pair :shock: :oops: ... we'll see how good they are.
PS... Happy New Year to all

Hello Hugh
if you don't mind please post a link to the diamond wheels you found on ebay, thanks

Hi Richard... here's my first approach - I did order these.... proof is in the grinding! I also ordered a 600... not sure where that one is ending up yet?

Those are flap discs, not bench grinding wheels. You want something like this actually (unless you intend to use your angle grinder to sharpen your tungsten?

I bought a flat disc like that and added it to the side of my bench grinder, it works but the angle is sometimes awkward.

I used to grind tungsten on a grinder for years and I purchased a tungsten grinder about 6 months ago. Worth every penny. Spent a little over $200 on it so it’s a low end model but the time it saves and perfect tip every time makes it worth it. Just my 2 cents.

Which grinder did you buy?

It is a standard Tech South tungsten grinder. I know some aren’t impressed with them but I’ve had a lot of success with mine and use it almost daily.
