- 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 ;)
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!
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
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!
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.
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....
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.
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.
Well done Tyson! And you’re right, beautiful knurl!
DUDE! THANK YOU FOR TAKING THE TIME TO TEACH US THIS!
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.
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. 🇦🇺👨🏭
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.
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.
It was good to see the knurling setup. Even better to see tool offset and how it related to work offset. Thank you.
Very Clear and to the point.
Great Stuff !!
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.
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.
Thanks guys for sharing the video...
very well explained.. I love it. thanks for sharing the video.
Very nice Tyson!
Excellent video!!! Very informative.
I didnt know you could knurl on CNC machines, nice vid!
Thank you, a pleasure to watch
thats the cleanest machinist hands i've ever seen :)
Very nice video, you are doing good at explaining :)
I want to thank you for this beautiful video
You should check out the Dorian cut knurls....they actually remove material vs upsetting the material...much less tool pressure vs standard knurls
Finally! Some CNC knurling!
Tysons of CNC 💪🏽
Thank you sir well done... very clear and helpful
Nice tutorial man, great explainations
Beautiful. I wish you showed before and after cutting
thanks very informative step by step professionally done
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?
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.
I need to bring the barbells at my gym to work and do this lol
Awesome vid.
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.
Enjoyed it!
Cool video! Thank you
Great tutorial, for me You're better teacher dan..... :-)
Great video
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
Just as I was thinking "I enjoy not hearing any "boom" in this video", there you did it ... But pretty cool video anyway, thanks.
Good stuff 👍
Great job
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 :-)
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?
Can't believe it. A minute ago searched Google for knurling info 😁
Enjoyed, thank you!
Can you do the same on a tube? How thin can it go? Great video
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
I like the pass to soften it.
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.
LOVE IT!
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.
wow, what a machine
great knurling tool. .. the wheels even look a bit rounded :)
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.
i was curling..but duble line creat problem.please tell me .what solution of this problem?
Gotta show this to my boss, he's always scared when he has to do knurling. 😂
How did it go, friend? :)
Hello there thanks for sharing this video but ı couldnt understand what should ı give to machine f and s values
very good thank you
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!!
Great video, can you share the program sample used?
thanks
How do you make sure the diamonds line up and the pattern makes a complete circumference of the piece and does not leave "half a Diamond)?
To quote @ThisOldTony, “It just does.” Thats honestly the best answer I’ve found. They call it the “black magic” of knurling. 🤷🏻♂️
I already know all this, but I love watching these videos. Great video.
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
Hi, Good video, did I miss the feed rate and rpm that you rand the knurl?
At those SFM I’ve always had heat problems
I’d like to see the coolant pumps
What feed rate should you run a knurling tool at ?
Amazing
Im going to give it a try on my '96 HL-2 Lathe A+ guys
Thank you so much Tyson! Whenever I have to do this I will reference this video.
Good job....
Knurling a 3d pattern on mild steel rod and which coating sir you used . That will helpful and enteristing.
FROM INDIA .
Beautyknurl! ;-)
Nice video thanks 👍 what is the proper name of this knurling tool
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?
will this holder work for striaght knurls as will as diamond with two striaght knurls
Does increasing the feed stretch the diamond or is that set by the knurling die?
Great. Thanks.
It’s funny when I was first taught knurling by and old timer who only programs longhand and is way out of the current time he made it sound like it was way more difficult then it was. I mean he got into the pitch of the knurl, found out how many perfect pitch lengths would fit into a circumference to determine how deep to make the knurl, it was like and hour explanation of unnecessary math just to make a handle lol
Is it possible to use this machine or similar for longer stainless steel shafts? 6-7ft?
What is the better speed and feed for 4.250 OD, Diamond knurls, what about the offsets on X?
This is kind of half the process, you also have to pick the pitch dia of the knurl your using based on the stock dia to get a good knurl.
As a turning guy that hates knurling haha where did you get your .030 depth according to pitch?
Hey.. Can you guys pls make a video on how to use a boring bar?? TIA
Thanks ❤️
Hi Thank you for your great video, Could you write a sample of a short program for Knurling?
Tyson, I have to say you are much easier to watch than the big roided up muscle guy. Thank you for making this video.
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
Ok, Is it possible to knurl an piece that is not perfectly round for instance how do they accomplish knurling the front and back straps of pistol grips?
How to calculate rpm,feed rate and minor diameter. Which code is used for knurling
