I love how the knurling isn't square. All my checkering files make for really clean, square knurling, but the gentle curvature of the lines made in this process is gorgeous.
I will now be looking @ knurling to see if it is square or rotary cut. Very subtle. Going to find an example of square cut now to compare the process....
Very true, if you did not know that the cross slide was moving along with the bit sweeping across, you would not easily see that the lines are not straight. But armed with that knowledge, you can pick up both motions in the final cut. Still a very interesting process.
The large offset of the cutting tool minimized the curve, but it also cause the chatter we could hear. It was quite apparent on the workpiece after the first direction cuts, and while we could hear the vibration (which was causing the chatter) there was no sign of it when we saw the finished piece. I don't know if he slowed the spindle down and took some spring passes, or polished the piece with a wire wheel perhaps?
It never occurred to me that you could put the tool in the lathe chuck and the workpiece on the slide. But it makes perfect sense that it would be possible. The overall forces the lathe experiences should be pretty similar in either case. Thanks for sharing! This is really creative.
@@jttech44many of the smaller "hobbyist" size lathes (like Craftsman, Logan, and Southbend) have optional accessories to turn the lathe into a mill by mounting a sideways table and vertical screw in place of the tool post. I hear they're not the greatest thing to use, but OK for a hobbyist who might not want to pay for an entire second machine if not used often.
Hammers, meat hammers, legs that grip a surface, knobs, screws, all sorts of decorative stuff, can be used against another knurled surface to prevent rotation, etc etc. Usually you do this on a mill, but, can be done on a late like this if you get creative with the fixtures like they did.
Wow, very surprising, I watched the work thinking, how is he going to do that with a lathe, and now I'm still thinking, how did he do that !! Bravo, Thank You.
Thank you for watching. This is a work piece for demonstration purposes. I think it can be used for contact surfaces and decorations that require non-slip.
I was thinking more of the spiral inside the three jaw chuck , if you take the jaws out and look at it , but I think they are probably milled out as it is a much heavier cut and I expect a slot drill is used to make it with a rotary table geared to the cross feed of the mill .
The same effect can be done on a milling machine with a fly cutter, the one difference being that you can take multiple passes on the lathe. Good video.
@@SetKat-Alex when you complete your first pass, and return to your original position, you will need to manually reverse the feed, that momentary delay would likely be enough to throw the spindle rotation and the feed out of phase. Unlike a lathe, a mill does not have it's feed directly connected to the spindle rotation.
Good job! I'm just curious, though, what kind of application face knurling would be used for. I can't think of when you'd need grip on the end of a rod.
The tool turning in the check and the work stationary in the tool holder. I'm no machinest and I never saw that. Have you folks that work in machine shops ever do this sort of thing, have the tool spin in the chuck of the lathe?
Very nice setup. This looks like a relatively cheap way for a hobby engineer to put professional looking knurling on custom vice jaws......... Well, cheaper than buying a ram type shaper machine just to do the job. :)
I think it will be tricky with long parts. Perhaps it's not so bad if both the knurling axes are at 45 degrees to the long dimension, but that's hard to hold. It won't be as fast but I think the old "put a v bit in the lathe and mill with it" might give better results
@@michaelandersen7535 I was thinking along the lines of bolting a vice jaw blank onto an angle plate (Using the reliefed holes that the jaws will eventually be mounted to the vice with), then mounting that close to the near end of the top slide, and as far above centre as you can without having the jaw get swiped by the cutter while it's at the back of it's swing (..... Did that sentence make any sense? I've re-read it a few tines and it still doesn't feel like it quite reflects what I mean). Once you've done one direction of cross hatching, move the angle plate/jaw setup to the rear of the slide and do the other cross hatching on the back swing of the cutters travel. It should result in a cross hatch that curves in slightly at the top of the jaw faces.
A slightly different method, but this is far from new. Ornamental turners have been doing much the same and far more complex for hundreds of years. It was still fairly clever to figure out how to set up the spindle rpm and cross feed ratio to do this automatically.
Awesome work! something to try but unfortunately my lathe doesn't have that screw cut option. Im upgrading to a PM this winter then I will try it out! 😁
He is cutting it with the cross power feed. Note he doesn't disengage the power feed between cuts. You usually can transpose gears on the back of the head stock to get pretty high feed rates.
I agree, my little 7x14 lathe doesn't have that power cross feed either and so I can't use this procedure as shown. I would have to make each pass full depth and then feed in by hand for the next pass. It can be done, it's just a lot more work. Move to slot 1, cut to depth, pull back, move cross slide in to slot 2, rinse and repeat and repeat and repeat...........
You can do this without a power cross feed, it'll just take *forever* because you can only take one cut at a time. You can take one "row" to finished depth at a time though, which will save some time. Hardest part is grinding the cutter profile honestly, that was a real piece of art.
very nice job... can i ask you?... how synchronise the movements between the spindle and the slide?... thank you very much for sharing your skill and expertise.
Thank you for watching. I used the automatic feed of the lathe. I did not release it until the depth of the groove was ideal, and returned it by reversing.
Thank you for watching. As a hobby, I was thinking of knurling flat and tapered parts. By chance, I noticed this machining method because some of the parts processed by the milling machine looked like knurling.
Thank you for watching. The cross slide moves in conjunction with the main shaft. I'd like to increase the feed speed, but since it's an end face cutting feed, the limit is about 0.8 mm for genuine gears.

I thought it would be more visible that the cuts are curved and not straight but I can hardly see it on the finished product. Looks great.
Yeah that was the part that I was wondering about, too. The setup made sense to me, but I expected the curves to be apparent
Very true, if you did not know that the cross slide was moving along with the bit sweeping across, you would not easily see that the lines are not straight. But armed with that knowledge, you can pick up both motions in the final cut. Still a very interesting process.
During the video was thinking could do on a shaper and have straight lines but the final result looked fine as it was.
If the cutter was rotating in a smaller arc the knurls would be more curved.
The large offset of the cutting tool minimized the curve, but it also cause the chatter we could hear. It was quite apparent on the workpiece after the first direction cuts, and while we could hear the vibration (which was causing the chatter) there was no sign of it when we saw the finished piece.

I recently learned how to do this on my Atlas shaper. Never dreamed of doing on a lathe. Very creative thinking and beautiful results.
I am going to try this on my shaper too.
Certainly unconventional, but definitely innovative 👍 That's pretty darn cool all the same!

Such a slow process, but the outcome was amazing. Love watching this gentleman work.
Choice of material and insert can make the process faster
slow ? i dont think so 5:50 ? we do cross knurling with our 5axis machine and honestly this method is maybe faster :D
The curves give the face the appearance of being spherical. Very cool.
Beautiful result, I never thought I could trust Power feed so much!
As long as there is minimal backlash, and you don't disengage the cross-feed when reversing, it should work just as shown.
Super cool and interesting technique! love the curvature of the knurls that comes in the final outcome, it really makes for a beautiful finish

Very nicely done - bravo!
that is really awesome and a beautiful finish. it was amazing to see the smoke coming off on the first pass. lovely work!
This looks fantastic, I like the slight curve in the knurling 👍👍👍👍👌👌
Great work and setup! If you go slow you can get away even with the most unvonvetional setup!

Thanks for sharing! This is really creative.
It more or less turns it into a horizontal mill, which is where this would usually be done, hence the unorthodox fixturing.

Brilliantly genius! Now I have to think of where to use some end knurling!
Find a way to mount one of your hammers. This sort of end cut is used on some framing hammers to cut down on bent nails.

Instead of rotating 90° once, I wonder what it'd look like if you rotated the work 60° twice 🤔❤

I don't see why you couldn't do multiple passes on the mill, as long as you keep the feed engaged?
