How Knurling is done
A short instructional video concerning knurling.
This video tells about the various types of knurling and the best applications.

Love the pattern this created! Who knew that knurling could be mesmerizing!
thank you Ray

👍 there can be math involved for knurling too if you want to calculate the blank diameter. Kinda like cutting a gear to see how many teeth will fit on the circumference. Dorian Tool has some good info on the subject.
You are 100% correct it’s basically the same as making a year depending on the pitch I will have to check out the website that you suggested Thank you for taking the time to comment much appreciated Ray
One of the best teachers at CC
Simon is a good
Actually the comment was directed to you.
@@mike-oz6iw Even better
I am a traditional WetShaver and in a lot of the Safety Razors I have , have excellent knurling
same here!
Nice video as usual. Enjoyed watching this.
thank you for taking the time to comment and for your nice comment Ray
shop and math anytime!
A big thank you 👍👍
Good video, thanks.
what an epic video i had a real riveting experience
Thank you for the nice comment and also thank you for taking the time to comment. It’s much appreciated. Ray
I would usually finish a knurl in 2 or 3 passes, never broke a tool or wasted a part form bad cut. btw, looks like bodies for albrecht chuck Rock on!
How does the tool hit the same place grooves again and again instead of just making a mess?
Same question here
By using carriage you can make the accurate cut
I believe because the diameter of the tool and workpiece have a certain ratio
Very informative video, thanks
Thank you for taking time to comment much appreciated Ray
So the embossing Knurling tool is pressed on to the piece with a lot of force? Is that how embossed knurling works? Also how much force/pressure would you use to get a good effect on the piece thanks for this video. How do the scissor knurling tool produce enough pressure to emboss also.
it’s not really the amount of pressure it’s the amount of pressure. It takes to embed a certain distance. if your machine is not very rigid, you are better off, going with the scissor type because it compresses on the top and bottom, and will require less force from your cross slide and compound rest I have another knurling video coming out. It’s more of the technical and not actually a practical demonstration but that’s gonna be six months to a year. Hopefully this answers your question thank you Ray
Not sure if I missed it, but what feed rate do you use or how do you determine how to? I can never seem to find out
what we used is listed at the beginning of the video it depends on the material and the diameter
I’m a cnc student and I was curious about this today. 😂
Hopefully you found the video useful And thank you for taking the time to comment Ray
And how it doesn't always go quite right...
how knurling will be done in production
Interesting that no lube was used on the actual knurl surface. Seems like every other demo I have seen uses lube, liberally. New to me, was using a knurling operation to emboss numbers and the like on dials. Thanks, well done video.
we should have used coolant in the knurl and oil on the studs but we were videoing and would not have gotten the shot
Typically when you're watching machining videos, they don't use coolant because it will end up eating through plastics on the camera and end up ruining footage.
And I too have read that lots of oil is to be used during knurling but after watching this video I'm starting to wonder if the oil just keeps the chips suspended to be ground I to the developing pattern and thus my poor knurling?
I don't understand how it makes a diamond pattern when the teeth are all angled in the same direction... is the lower wheel angled the opposite way?
Yes, the lower wheels in a different direction
Apparently the backlash in the feed doesn't hurt results ??
the machines are in good shape there is more play in the knurling tool then in the machine
If after nurning diameter 35 or something. What is the formula for before nurnling diameter/ blank diameter for nurling. Plz replay🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻 any formula.
👍👍👍
How can we knurl flat brass rule which is 3 mm thick, 1 inch wide and 1 metre long. How to knurl on side which is 3 mm thick?
Do you have a milling machine with 1 m travel and power feed?
you can flat knurle with a milling machine and there is a process called dimond cutting
i don't see a credit or link to Simon... did you forget to add him
I absolutely didn’t forget about Simon He’s a great man And an excellent instructor
@@shopandmath please drop a link to his channel - no idea who he is other than 'Simon'
Is your school in Toronto?
This was filmed at Conestoga college in Kitchener Ontario
Oh Kitchener. I got excited for a moment.
Great if you have reverse!
Thank you for your nice comment and thank you for taking the time to comment. It is much appreciated this videos or description for my students on how to create that exact knurl I plan on doing a future video of all the theory or proper neural should be done. Thanks again Ray.
Hi, what size 'Cut's' are you inputting on the cross slide? I heard 3 thou mentioned, what is your initial 'Cut' so to speak of, Thank you
It depends if you have the knurling head perpendicular or if it’s on a slight angle If you’re cutting aluminum or nerling aluminum you can go much deeper per past than you can steel Depending on how Rigid your set up is I show the students how much pressure not really depth because the tool post will spring back What if I had to guess I’ll probably say first pass 0.02-0.03 And after the first pass probably about 0.01 On manual machines the depth isn’t quite as important as continuous pressure Your tool post will spring back On less Rigid machines Hope this helps Ray
@@shopandmath Thanks for responding
this is strange obviously the end result shown at the end of the video is no matching the result shown on the video, i came here coz i have the same exact issue if found here!. notice at 5:52 you will find one of the wheels is double marking, for example making 0.5mm pitch instead of 1.0, notice the shape drawn is like double in length (not a square), in that case it is impossible to fix unless you start over, notice also when he continue to knurl it came out pretty messed up
Sorry there’s no conspiracy theory here same part same guy same Cut There was no mixing matching Simon will get a kick out of this though
@@shopandmath one of the wheel is splitting the pitch, you dont see that?! it is a known issue
One of the wheels is producing a double tracked pattern. That is why it looks messed up. What you're looking to achieve is even pyramids which this isn't I don't traverse back and forth loads of times as seen here but just apply a firm bite at the starting point and hit power feed when I see fully even opposing pyramids.
@@howardosborne8647 yeah and i dont understand how shop and math cant see that!, i solved that problem already as you said
Need video on cabinet maker
Cabinet making is in the woodworking department
Try knurling a 6" round stock 6 ' long with a crown in rhw roll lol ,your in for a long day if your scared to knurle
That sounds excellent. Would love to see a video or a photo of the finished product.
@shopandmath I would have love too video it ,but company policy no video to phones ,people don't believe I did it lol ,but I did
For a video about how to knurl there is a severe lack of how to knurl. Total waste of time.
Thank you for taking the time to comment
Clicked off when you said you were going to be hard to hear because of the mask
My thought exactly. Hope the mask gets caught in the lathe.
Hahaha,who the f_c_ wears a mask in the shop?...
Scissors type are the only way to go. Even the cheap ones we can get down in the States for $60 from Victor Machinery.com work very well. The pins for the wheels are made from mild steel and need replaced and then they are good to go.
Best results I've had are from scissors types
