- The setup with the custom fixtures works GREAT! Except for one slight problem...a tool broke on the last run. And this is not just ANY tool, it's a Cogsdill burnishing tool. In this episode John talks about the benefits of this kind of tool, and other tricks he uses to maximize tool life.

Never heard of that burnishing tool but that's pretty cool. I would imagine that cold forming the metal like that will increase its hardness and give you a more durable bearing surface.
Yeah i totally concur with your comment. Im thinking it does alot of what shot peening would do but a more in contact process.
That is exactly what the Cogsdill Roller Burnishing tool does - there is more information on the process on our website here - cogsdill.com/products/burnishing-tools/
Hey John, thanks for the great video and recommendation for our tools.
Cool to see manufacturers get involved in the conversations!
This would work pretty well for us in a couple of applications... but please tell me these are repairable. $700 is a bunch of capital to have at risk with such a delicate tool.
@@Dakakeisalie We love it when our customers post stuff like this!! Its awesome
@@LumaLabs Yes these are repairable - looks like the cage, cone and rolls are shot and these are all replaceable. Heres the link on how to do that... ruclips.net/video/irGHsFhFDOQ/видео.html
@@cogsdillnuneatonFor the love of god, don't let Grimsmo know... Otherwise you'll miss this quarter's numbers! =)
Oh man.. thats a painful break cost .. I get thats its industrial pricing but jeeze... glad you guys are making the $$$ to cover that kind of maintainence cost
I think I had mentioned burnishing as a fine finishing op several times over the past couple of years so glad to see that you are using it! Have you tried roller burnishing on the faces? That could be a much faster method than the lapping and achieve the same surface results. I use a roller burnisher on cam and main journals on engines and it works fantastic.
have you guys seen the new face burnishing tool (DBFM) - the link is here - ruclips.net/video/ViyyRlpT53g/видео.html
I feel your pain. I'm supervisor at a machine shop and had a guy smash a 1/2 inch burnishing tool. Not good. I'm glad every thing else worked out.
Hi John, You should look into purchasing a 4th axis with a trunnion. Imagine the run time with that.
i run those for finishing oring bores, the most stupid break we had was the machine got put on osp and the operator changed the part, the burnisher is definitely not a good drill bit. so far we have found best reliability by reaming then rolling for final finish, seems like more work but it is still less than honing the final bore
We use them at work. I get the rollers and mandrel ticn coated and it easily doubles the life of them.
Nice bid. At $850 a pop I'd be coming up with an in-house solution or discussing other options with my supplier.
Cogsdill will repair them, no need to replace the entire unit
Awesome hair day :)
I didnt understand how this tool works. Can you explain it with makro recordings please?
I found it by myself: ruclips.net/video/IDZkHCaAu1I/видео.html
When a small error equals a big mistake. soo much can go wrong when machining.
Burnishing is a finishing process....no need for lapping post....
...unless you heat treat it after burnishing...
Not exactly "failing cheap"
