I BUILD a Knurling MACHINE for Serial Manufacturing

[@Matthews_Tools]

We made this machine for serial production. But why, when it could be done on a lathe? Because we want to knurl D5 aluminum and copper bars with perfect precision, which is impossible on a conventional lathe, because at such a small diameter the material will bend rather than knurl. We tried it with a follower rest, but it's still not perfect. We tried to play with the rpm, but it wasn't perfect. That's why we created an effective device that is easy to use. . If you know a method how to knurl D5 bars perfectly leave a comment here 👇👇

[@TheDude19Echo]

Ok, so make your machine so you can knurl aluminum and copper bars with perfect precision, so what's the problem? Just a side note, you aren't getting perfect precision and you won't be able to knurl every diameter. Any gear maker could verify this. Not sure why you stuck this machine on a table in the middle of a field then zoomed in from far away either. Not sure what drugs you're using but I guess.

[@Nevir202]

@@TheDude19Echo That is a wild bunch of sludge you wrote. He won't get perfect precision because it won't be perfect at every diameter? Who TF said it would be? He specifically mentioned having a problem doing it on the lathe at this particular small diameter, which was needed in production quantities.

Hey, awesome work! Really great design. There are 3 ways you could make your part using existing machinery though. First, is to use a knurl holder with 3 wheels mounted to what looks like a 3 jaw chuck. Instead of clamping jaws, it has either cut knurl wheels or form wheels. Quick makes one that i have but other brands make them as well. Second method is to rotary broach them using an external spline tool. I have done this for making components for household tap valves. You need an EDMd spline tool. The limiting factor factor on both these methods is that when you want a really long part, it twists too much and won't end up straight. The third method that avoids that pitfull and is basically the machine you've made is called a straight acting thread rolling machine. They are most commonly used for high volume production of rolled threads, but they use plates that can form any geometry onto the part. I once worked on a part that used this type of machine to produce a pyramid shaped knurl on 8mm x 200mm stainless rods. The dies needed to be sinker edmd from hardened steel so were very expensive but then a perfect part came off every second. You need to have a gradual taper on the forming plates from when the part first engages to when it is at full depth, so the wear happens evenly over all the ridges. Great work

[@hinz1]

Knurling surface, that's why you want to have a shaper ;-D

[@KnowArt]

would love to see what happens when you put it in slightly diagonal, two times in different directions. See if you can create a cross hatch

[@Matthews_Tools]

We tried that and the lines crossed each other. Looks different. I will make short video about it

[@andwjy]

I guess whoever uses this machine is an official serial knurler indeed.

I bet your boss was shocked. "You wasted 6 months of time and machine hours on a contraption that straight knurls! I can do that on a lathe in 30 seconds!" Like an engineer you went around the world to get across the street. But, it was some really cool machining. So you get a like and subscribe from me.

[@Darlhim89]

Lol, pretty much. Not sure straight knurling has much use but its still a cool project.

[@Matthews_Tools]

We made this machine for serial production manufacturing for the"cigarette roller machine". We try to knurl D5 bar for every kind of methods and the bar not was as nice and smooth as we want. I try it with follower rest on lathe and the results was not impressed me. But this machine is very simlpe. Just put in the right lenght D5 material and the machine made it probably 15 seconds. Nice, smooth and no material waste. But yes unfortunately it was a long long time to make it. Thank you mister!

@@Matthews_Tools Now I understand why you made it.

[@Darlhim89]

@@Matthews_Tools fair enough. Either way extremely impressive display of machining talent and design.

[@Anoneom]

There are many reasons to do things in a different way. This machine is more space efficient and cheaper material wise than a lathe that can do a nice straight knurl. I thought of these two reasons before reading the makers own third reason. When I see someone making a machine with this many and diverse manufacturing skills I assume they know something I don't.

is it possible to make a knurling machine that makes parts for a roller screw actuator in 1 step? like can you get a screw that becomes also a gear on both ends?

I think it is possible, but a very special device must be manufactured for this. and maybe 2-3 times as big a machine is needed due to the power relations.

Also good thing its just labeled knurling bc not one of those samples has equal spacing that lines up perfect from the start point to the finish point! You made sure to not show it after the first one showed it! Since its inconsequential knurling.....im sure itll be ok....but the time and effort used....for it to not create perfect spacing is just ludacris might as well not even made the god dahm thing!

[@thebigdustin]

I cant tell if this video is a troll or not. Your bottom slide plate has what looks like deformation where you screwed in the lead screw 8:14. That will probably crack and fail at some point. The miss matched hardware all over the place 22:45 and then watching your machine literally self clearance while in operation 28:06. Could have saved yourself a lot of time and material by just building a free floating clamping style knurling tool for the lathe.

[@jesperwall839]

It’s usually the other way around. Water transfer the heat much faster, and you risk getting cracks or warping the part. It also risks getting the part too hard, or even brittle. Usually heated oil is used to avoid this, but water works just fine sometimes, as in this video 👍😀

firstly, its not impossible to produce on a lathe, its a hell of a lot quicker and easier.... There is nothing perfect about a pressure knurl... A £150 cut knurl a day to mod it and your set.... You could of produced 50,000 of these of a much higher quality in the 6 months that took to make....

[@Matthews_Tools]

No. I tried many different methods on the lathe and the surface was not smooth at all. I also put a follower rest on it, but it wasn't the real one. since it has a diameter of 5 mm, it bends easily in the machine rather than knurling. 6 month because I'm a student. I could very rarely work on the machines. I would have made the device in about 1 week if I had the time and the machine. We need this machine for serial production.

Due to the fact that it is impossible to accurately set the teeth of the upper and lower plates relative to each other, the dents from them do not match. This is clearly visible in the resulting details. They have shavings and grooves with bullies on them. The mechanism is for a museum of curiosities, not for work!
