Awesome take on an old idea of tools to add a smooth shiny finish, but this is so much better than any regular form tool, I’m so impressed I’m going to make one for my machine, thank you so much for sharing
This is awesome idea! I was wondering what was he doing throughout the video but at the end, it’s awesome!! I must agree with a previous viewer that it would add hardness to the surface and that makes it even better! Great job!!!
Machinist? Or Wizard? You decide. I’m willing to bet this tool adds a certain amount of surface hardness to the part as well. Very impressive. I’m going to have to make one of these. 😊
Doesn't add hardness unless the material is work hardening kind (like 304 stainless). Surface tension goes up, as this is imparting the same type of stresses to the material surface as cold rolling/forming/drawing does.
I`m not 100% who did a video on the topic, but if i find it, ill tell you here, but there is someone on youtube who made a certain roller burnishing tool for the milling machine... The pattern that that thing leaves is wicked... An absolutely stupid idea in my view... Allegedly it was thought as a good idea at one point in the past to replace scraping, but the only type of scraping it could replace is the scraping for oil retention, and even there, you would have to re-grind the surface as the burnishing rises the surface around the valleys... Not just that, but you still need a monstrously large machine that is monstrously precisely hand scraped for precision to actually be able to rely on that kind of tooling to ``replace scraping by hand`` which is a bit of an oxymoron from where i`m standing... But as a surface finisher it is a damn brilliant tool... Depending on the speed it leaves tighter and tighter pattern, which by logic tells you that for oil retention - you would have to have the tool turning quite slowly as not to disturb the bearing surface all too much... If i don`t post which channel uploaded the vid, just search it out, you wont be able to miss it... If you like burnishing, the sight of the surface finish that that tool leaves will please you greatly... All the best! P.s. edit - the video is ``2 ball pattern burnishing`` by engineering hacks and tricks...
This is good stuff! I wonder whether running a shear-type tool before this would improve surface finish even further? Honestly, it might be worth me just trying it out to see. Thanks so much for sharing this!
Wonderful!! Please, what are: (1) the diameter of the bearing ball? Is it 11/16" = 0.6875" = 17.46mm? (2) the type of the ball bearing (d/D/h)? Is it 6202 2RS = 15mm x 35mm x 11mm? Tuyệt vời!! Xin vui lòng, là gì: (1) đường kính của quả bóng mang? Có phải 16/11" = 0,6875" = 17,46mm không? (2) loại ổ bi (d/D/h)? Có phải 6202 2RS = 15mm x 35mm x 11mm không?
they would of loved you at the training school .Only trouble is you cant shoulder the ball but nice idea it has not quite got rid of emery cloth and ground finnishes ttfn&ty
