The Art of Knurling | CNC Machining Tutorial | Vlog #87
CNC Machining - Knurling is definitely an Art. You can get 10 different Machinists from 10 Different CNC Machine Shops and chances are, each will have a slightly different looking knurl. Even when a specific knurl is called out on a print, it’s best to ask for a sample to be supplied... as what is intended, is not often specified.
In this video, Tyson teaches you a proven method that will give you a great knurl every time.
Here is more info on the Straddle Knurl Holder we used for this application. We do not know or work with the below company but figured we would give you the info:

Tool: OR SH-KP
Knurl: KP
Knurl Pin: C 164

Well done Tyson ! Very clear tutorial a pleasure to watch ;)
Very nice, detailed video Tyson. Suggestion - talk about the relationship between the part circumference and the tool circumference. Your pinch knurler won’t work on just any diameter. Thank you for sharing.
Hi Tyson, Many thanks for sharing. A very detailed explanation of knurling on the HAAS Lathe. Showing us the setup hows, and whys was very helpful. John
Subscribed because of how clear, and informative this video was. I have no CNC machine, but I thoroughly enjoy learning new things. Keep up the great work.
Right on time. Just knurled my first part last week. I was apprehensive at first but after all the fussing and worry , it wasn't so bad. Your way of setting the offset is much simpler than what I went through. Thanks for the tips and great video!
Well done Tyson! And you’re right, beautiful knurl!
love it, that was awesome, I run a cnc lathe at work, never even thought about knurling on it, we use the manual lathes for that. I can totally see how a higher production job would make use of cnc knurling, and I honestly didn't even know that was possible!
DUDE! THANK YOU FOR TAKING THE TIME TO TEACH US THIS!
Excellent video! It's clear and concise and all around very well presented. I really appreciate what you guys are doing, it's a huge help to people who lack proper job shop training.
Woah! One of the beautiful Knurl I've seen. Definitely a class tutorial this was.. And the Boom was Broken already! Nobody could say Bhoom like Titan, have a nice day to you too Tyson of CNC....
Im about to knurl for the first time tomorrow. This video makes it look very simple and frankly takes alot of the edge off.
@Tyson awesome vid ! Crystal clear. Great application example with the ROV.
Great video guys! When I did knurling on parts at my old job (which was a lot Haha!!) during setup, I did a skim pass on the material such as you did, and for example a 1" diameter turned down to .985---after that I took our knurling tool (which had the same knurling wheels as what you have) and lightly touched off on the O.D. of the part (.985) and hit X diameter measure button and entered the .985 and then hit enter. From there in my program I would write for my knurling tool to enter rapid in Z-.100 to get started and feed down to X.965'ish , depending on material your knurling and visually check the knurl finish. One trick I learned was to watch the amount of pressure on the X axis as it was knurling and put that note in the program for future runs. Usually for stainless my X axis pressure was around 25-35%. For aluminum it was much less, usually around 10%. I forgot to mention, that I ran a HAAS SL20 and SL30....not sure if other CNC lathes have that feature of X load pressure.
It was good to see the knurling setup. Even better to see tool offset and how it related to work offset. Thank you.
very well done instructional video. Thanks so much for taking the time to upload your content!
This is so cool. Thanks so much for showing that on a cnc ! I’ve only ever done it on a manual machine! Looking forward to trying it on our st-30!!!! Great job man! Keep the lathe vids coming ! That’s my machine of choice to !
Tyson you have done a excellent job of explaining all the workings of what you are doing mate thanks very much for the education buddy. 🇦🇺👨🏭
Nice video. We look forward to seeing more turning videos like this.
"Ditto" great job crystal clear !
Nice! . A different way of touching off. Still got the same results. I generally run the spindle slow and move the knurl tool down till it starts spinning on a known diameter and call it that diameter. Also I run the neural off the edge and the z until it stops spinning and I call that z0. Let It go from the door today I guess that's from me running manual for years. All depends on how you program it but that was a great tutorial thanks for showing everybody. you, your dad, and the whole company are doing a great job for the industry. And there's always more than one way to do it! keep thinking outside the box it's what our industry needs to succeed.
Very Clear and to the point. Great Stuff !!
Thanks guys for sharing the video...
Very nice Tyson!
I have been taking the academy classes for over a month now. With the Fusion software, I figured out how to make convex and concave surfaces. Titans program is so addictive.
Excellent video!!! Very informative.
Tysons of CNC 💪🏽
very well explained.. I love it. thanks for sharing the video.
Finally! Some CNC knurling!
thats the cleanest machinist hands i've ever seen :)
Thank you, a pleasure to watch
I want to thank you for this beautiful video
Beautiful. I wish you showed before and after cutting
I didnt know you could knurl on CNC machines, nice vid!
Nice tutorial man, great explainations
I’ve been silently judging manufacturers for decades from their incomplete knurls.
Glad I'm not the only one xD
Hard to say without the lupe or microscope 🔬
You mean the diamond shape has to perfect squares not rhombs at least in my world.
You should check out the Dorian cut knurls....they actually remove material vs upsetting the material...much less tool pressure vs standard knurls
Very nice video, you are doing good at explaining :)
Thank you sir well done... very clear and helpful
Awesome. Should have also showed the live tooling milling the flat that was on the part. I've only used a knurling tool once and had to wing it but make due, this video is helpful.
In The Shop below mentioned doing convex and concave knurling. Titan, is there a chance on doing a video on flat plate, convex and concave knurling?
thanks very informative step by step professionally done
Great job
Enjoyed it!
Hi, Good video, did I miss the feed rate and rpm that you rand the knurl?
I already know all this, but I love watching these videos. Great video.
Thank you so much Tyson! Whenever I have to do this I will reference this video.
LOVE IT!
Awesome vid.
Amazing
Great video, i just finished a run of 9000 knerled pins today great timing on the vid. was currious how well that tool you used in your video might compare to the style ive been using. My tool is not adjustable and i have to use a live center because of the amount of pressure in x i neen to get a knerl. What id like to know is by using the tool over center line of the part what kind of loads are you looking at. Would be nice if i could get rid of having to center drill and use the tailstock.
Great video
Chamfers front and back will make the part look a lot better. You should also emphasise the feedrate used as this is important to the quality of the knurl based on the type of knurling tool.
the feed rate will vary ---that's why he did not mention it ---but you already knew that
@@davidwrighton3914 Yep, but it is important, wouldn't you agree?.
I had two main questions and that one one: 1. Isn't feed rate important - and doesn't it need to be a factor of something - i.e. like the dimensions of the knurling tool ?? Does it need to by in-sync with the rotation, like when threading? 2. Does it need to be synchronized - if you're doing multiple knurling passes - like with threading?
@@Bkgoodman11 Hi Brad,1. As a rule of thumb a feedrate on softer materials can be as much as 0.020" , less on tougher materials. It therefor does not need to be in sync. The depth of cut can be up to 1/2 the depth of the serration in the knurling wheel. 2. I always try to get to depth in one pass ( on finer knurls), but if you need to take multiple passes, leave the feed engaged and reverse the feed direction.
Enjoyed, thank you!
The knurling tools I used came with a datasheet telling you the offset. So I never need to use a shim or something to align
Tyson, I have to say you are much easier to watch than the big roided up muscle guy. Thank you for making this video.
Good stuff 👍
Just as I was thinking "I enjoy not hearing any "boom" in this video", there you did it ... But pretty cool video anyway, thanks.
I need to bring the barbells at my gym to work and do this lol
Cool video! Thank you
awesome, it's really inspiring, i was wondering if we can knurl flat part on milling machine on top face?
Great video Tyson. I have a question. I am an old school machinist. I was trained in trade school in the early 80s on manual lathes. Knurling was one of those things that sometimes didn't form the beautiful diamond your part did since the knurl rollers aren't synchronized. Sometimes we would get a cross knurl or double knurl, where one roller would make the correct pattern, but the other roller would roll in a double pattern where it basically cut the other half of the diamond in half. Make sense? How do you consistently get that perfect pattern?
Beautyful job Tyson. Allow me to ask what brand of knurling tool holder you are using there? Are those roller tapper from both ends? Thanks Tyson.
great knurling tool. .. the wheels even look a bit rounded :)
Hey, Thanks for making it look like flawless. How can we cross knurled perfectly on tapper parts, I mean those parts which are in conical Shape ? Thanks.
Can't believe it. A minute ago searched Google for knurling info 😁
Great tutorial, for me You're better teacher dan..... :-)
Your really taking to this video production game and improving with each! Your going to give your old man a run for his money someday but need to work on the BOOM a bit :-)
Can you do the same on a tube? How thin can it go? Great video
wow, what a machine
Beautyknurl! ;-)
Nice video! Thank you for posting it! 2 quick questions: 1. What is the hand of that tool? Left or right? I’ve been shopping for one and it seems like it would be a left hand tool you want....or an upside down right hand tool...... 2. Are you using beveled wheels or straight edge wheels? Thanks again for the the great video!!
Good job....
At those SFM I’ve always had heat problems I’d like to see the coolant pumps
Where are all those Z offsets taken from is there an absolute zero taken from somewhere on the machine, the minus number seems to increase the nearer you move the tool to the chuck? Interesting video thank you
Great video, can you share the program sample used? thanks
Cool video. But I am accustom to gears. If gear spacing between teeth is not careful matched they will clash. How does the tool maintain the correct distance between knurled lines?
Im going to give it a try on my '96 HL-2 Lathe A+ guys
Thanks for the great videos! I was wondering if y'all can make one about machining screws or bolts. Watching Titans of CNC has got me trying to switching trades.
I know you're asking them but thought I'd just butt-in. You know that most screws & bolts are manufactured very differently, right? There are cnc screw machines but most are made with even more specialized machinery. They can do it but it's not very common because of the massive choice of mass-produced fasteners. It's usually far cheaper to find one that works for the application. Ed Grimsmo makes some tiny machine screws on his channel with a typical CNC lathe, for his knives. I haven't figured out why he didn't just find a way to design the knives to work with ones he can buy for a few pennies though. If you're gonna go that route, may as well make a custom head on the fastener so it looks cool and illustrates the expense better.
@@christurnblom4825 I only know videos here and read on a forum you can use cnc machines to make threaded parts like screws and bolts.
@@FirstLast-py2qe Yep. You can make practically anything your mind can imagine that could be made from metal or plastics, with the exception of some of the complex geometries made with 3d printing. You could still find a way to make the same shapes in pieces and assemble them though. Honestly, just making 1 or 2 bolts is done faster on a manual machine unless you've already got some stock code that can just be modified quickly and/or the fixturing & tooling to do it already. For instance, I've seen it done on lathes with live tooling. Start with the head & the bottom is flat, which is usually fine. If you're reference to switching trades is hinting at learning to manufacture fasteners to sell, I strongly caution against going into that idea half-cocked though. it's overrun with experts & money. Unless it's highly specialized fasteners that nobody or almost nobody makes, you're not going to be able to compete without millions of dollars. Ask Titan for a second opinion if that's what you're getting at. Anyway, check this bad boy out. I think the common vernacular for this is "machine-porn". kzhead.info/sun/oNevltNulnyna30/bejne.html
@@christurnblom4825 thanks for the information, my trade switch is for cnc machining, I'm currently working with duct/electrical/ plumbing. Cnc machining seems to require more thinking and it'll be nice to be home instead of traveling all the time
@@FirstLast-py2qe I totally get that. I did various construction and steal fab. jobs for 12 years then went through 8 years of poor health & barely being able to keep whatever job I could find. If you can find a way to handle being inside all day, it's nice to have that climate control and stay relatively clean. I work in a small job shop & often I'm the only one there so playing whatever music I want helps a lot. I'll tell you that it sucks getting out of school at first though because many of us become button pushers until the boss feels like you won't crash a machine. I got my own small manual mill & lathe so that I can keep learning. I couldn't see a world where I didn't have one, once I knew how to machine. Plus your friend needs a drive line shortened or the head on their engine is warped etc, you can help them out & they'll be extremely grateful. I just made a little part for the ball return in a bowling alley, for instance. 30-45 minutes, got $30 ...it all helps. Making whatever you want is awesome.
I like the pass to soften it.
Hello there thanks for sharing this video but ı couldnt understand what should ı give to machine f and s values
Great. Thanks.
KNURL ALL THE THINGS!!!
Hey Tyson !
Hey.. Can you guys pls make a video on how to use a boring bar?? TIA
Knurling a 3d pattern on mild steel rod and which coating sir you used . That will helpful and enteristing. FROM INDIA .
Thanks ❤️
Multi axis knurling of non linear parts with custom radial inserts next episode?
Nice video thanks 👍 what is the proper name of this knurling tool
Gotta show this to my boss, he's always scared when he has to do knurling. 😂
How did it go, friend? :)
As a turning guy that hates knurling haha where did you get your .030 depth according to pitch?
You got an ST30 Y, would be way easier to use the Y travel for the tool measurement...and it´s more accurate to touch off one of the knurl wheels one the part or your probe arm
very good thank you
5:40 Anytime I eyeball stickout, I somehow always end up with the chuck jaws wiping the oil off my parting tool but I somehow never crashed it 🤷♂️
Does increasing the feed stretch the diamond or is that set by the knurling die?
Hi Thank you for your great video, Could you write a sample of a short program for Knurling?
We have a 3/8 dia stock, we are trying to do a straight knurl with a double knurling tool like yours using the same SFM and feed but the splines look pretty bad
I love this dude lmao
Hey Tyson, what about selecting knurl diameter and TPI?
Kind of skipped one of the most important points of the selected knurl sets. RPM-IPM ?
@@garygriffin3114 faster feed than speed
wow, great video. so I just ran 280 stainless parts with similar feature sizes and it took 4 minutes for just the knurl tool path. are the wheels HSS? Cobalt? What brand knurler? What SFM and IPR? Our knurler was not straddle type like yours and the wheel weren't concave either (our were beveled).
From the video :) SFM = 250 IPR =. 012
i was curling..but duble line creat problem.please tell me .what solution of this problem?
TITAN IT UP!!! BOOM
