Deburring: Grinding vs Sanding?

[InspirationTool]

So... I have been doing my deburring on a belt sander, as that is what I have. Completely out of couriosity, would a grinder be a better choice? I'm wondering if grinders stay sharper longer than the belts on the sander.

Mostly I'm deburring 304 stainless rods that have been cut in a rod shear.

Thanks!

Jeff,

Personally, I think the belt sander leaves a nicer finish and is easier to control. The grinder, even with a fine grit wheel tends to bite a bit more, which on the end of a rod might not be as big of a deal. The SS work that I have done has been mostly with 17ga sheet.

I have wondered about a tumbler for deburring. I have read that they work reasonable well for aluminum. I don't know what media you would need for SS or if it is even possible.

There are several types of media for tumblers, from abrasive polyester composits to ceramics, steel shot, abrasive charged walnut shell etc, It really depends on what you are trying to achieve, and how much time you want to wait, I t could take a while but then you could be doing something else. Also for a nicer finer finish scotch brite type wheels or abrasive rubber are nice , but can be a bit pricy especially considering that they are ablative.

the media sellers are always happy to help with selection.

If they have been cut with a standard rod shear, it will be a little more than just a light burr usually [at least the ones I've used]..

One of those utilty bench grinders with the flat belt and round disk would probably work a little nicer, or even a flat disk mounted on an electric drill..might leave the final result a little more 'square'

enjoy..

I think that was what I was calling a belt sander. Is this what you mean?

Exactly,
a combination belt sander / flat disk sander...

they work great, I still make do with an old belt sander clamped in the vise upside down, or a drill with a sanding disk clamped in the vise again...

on my Xmas wish list, keep telling the girlfriend that tools are always a good xmas gift...
she keeps talking about dress shirts and stuff..oh well..
