Knurling from two Sides - The Perfect Knurling

[@rangita2]

That centering is so smart! The threads only provide compression, and the cone provides alignment. Very cool, will file that away.

[@mymechanicsinsights]

A center drill type B would actually work even better. Then your dead center angle wouldn't run into the thread. Also for heavy machining it might get tricky to get the part loose again.

I started watching your channel a little over 2 years ago, with no knowledge of lathes, mills, bench grinders, or much of anything else. Initially I thought that the lathe was operating with a computer program because it was so precise, but my brother informed me that that was all manual control. The precision of you manually shaping metals or lathing them blew my mind! But it turns out that you are Swiss, and thus your amazing skills are hereditary and passed down from generation to generation! The greatest mechanics experts in the world!

[@MaatStile]

[@johnqpublic4012]

Beautifully done knurl. We're fortunate enough to have a dedicated machine for knurling. We drop the part into a fixture (no clamping required) and the two 140mm wide knurling tools knurl the shaft in a couple seconds. But then again we're talking mass production so it's apples and oranges. In any case, your knurl looked fantastic.

[@SquatSimp]

What is this machine called that your company uses?

[@johnqpublic4012]

​@@SquatSimp It's a thread rolling machine equipped with knurl wheels. Rather than feed a rod through to thread it as you would when manufacturing bolts/screws, you build a custom fixture and drop your parts into the fixture to knurl specific sections. You can custom order the wheels in whatever width (up to the max for the machine) and whatever type of knurling you need. We're paying a few grand per pair of wheels and they need to be replaced after X number of parts. There are limitations, but it generally produces consistent results once you've got it dialed in.

[@SuperCuriousFox]

What are lathe dogs? Also, why did you have to start the knurling in the center of the handle, rather than at one end and then knurling continuously to the other end? The result looks great either way, I don’t know much about machining so I’m just curious if there’s a reason for this particular order of operations :)

[@peripheralvisions]

Came here to ask exactly that

[@paulbush7095]

Same here. I’ve heard the terms “dog & dogs” used as a name for various elements of machinery parts before but not as part of a lathe.

[@billshiff2060]

It's a simple clamping device. It has a hole in a block of metal with some means of screwing down something that is in the hole like a bar you want to turn. Then there is a handle sticking out of that block which is bent 90 degrees and that tang is positioned so that some part of the chuck or face plate can drive it such as a chuck jaw or slot in the face plate. The driving end is fitted with a center cone called the live center and the other end is a center in the tail stock. The whole system is called "turning between centers" and it has several advantages over turning in a chuck such as turning a taper with offset tailstock, the ability to remove a part and replace it exactly where it was etc.

[@paulbush7095]

@@billshiff2060 thank you. I think I can visualize that. I know it’s not an easy concept to describe using only words

[@VRWarLab]

[@auwtomoton]

Can you please say more about what makes you go from the center twice instead of going once across the entire length?

[@DavidLindes]

My take on this is that the edges of the knurl can't be reached with the tool from the other side. On the left, the 45° angle of the knurling tool slides in to the 45° angle of the edge; the other way, they'd collide -- or one would have to keep further from the edge. And even if not, I think the way the knurl ends would look different. (Then again, grain of salt; I'm far from expert on such things... just sharing my own thoughts from when I wondered the same thing while watching, since it's been a few days without an answer yet.)

[@ArniVidar]

@@DavidLindes Yes, the knurling tool hit either the chuck or the actual piece, and thus couldn't go all the way to the end. Hence, he needed to do it in two directions, and dead center was the best place to leave a line. :)

I don't quite understand why you couldn't knurl that in one pass. Anyone? Also, I've wondered for a while now - Do the ridges on the knurling tool have to be some multiple or fraction or something of the diameter of the part, so they line up every rotation?

[@ferretface]

I came here to ask this too. I think he's just flexing his shop skillz.

[@Vickie-Bligh]

@@ferretface No, it has to do with the reach of the tool (I'm not a machinist so I can't give technical jargon).

[@MudSharkDanceLesson]

Not a machinist here, but if you look at the knurling tool, you'll see that there's now way he'd be able to knurl the part on the far right due to way the tool and part are shaped. The knurling tool would run into the angled section and ruin the part.

[@SgtSly]

This may be a stupid question, but why could you just not use a knerling tool of the same pattern but oriented 180° in the opposite direction? Then flipping the part wouldn’t be necessary, you could just change tools.

Knurling is such a satisfying lathe operation. Especially the diamond pattern, the bump knurls tend give rougher edges. Frankly I'm impressed you're able to get the proper depth of the tool without double-tracking even once...perhaps there were some test cuts done somewhere off camera?? 😁 Your turning is also exceptionally nice as this doesn't appear to be a CNC so you don't have the option of constant surface speed AND you don't use any fluid in your turning (hence the smoke). Good machining and lathe work all around!
