Hardtail Vise Build Ep.12: Swivel Bolt Turned in the CNC Lathe 

We tend to use a torque wrench on our CNC chucks, eliminates human error on how tight each operator pulls up tight.

Hey Adam, one thing to look out for if your getting chatter on your threads is the stick out of that threading tool. I was running a job on our mazak lathe last year. 17-4 stainless steel and we had some chatter on the threads. Sunk the tool in as much as possible and it was night and day difference. That pretty much goes with any tool but i just remember that one particular job and honestly in my mind the tool wasn't even sticking out too far but definitely was enough to cause chatter.

Adam the weak link in your setup is the excessive tool length from the turret. Even if you have to cut the shanks you will gain maximum rigidity. Also check the lead in angle of the threader. Make it so 95% of the material removed is on one side of the vee (29.5 ° lead in angle). Hope this helps. You're doin great!

If you watch Jason's videos I think you will find that the choice of material being cast iron was to ensure that that part (easily replaceable) fails before the body or the swivel base. Using steel might mean that the failure point moves to something more catastrophic

In 100 years, someone is gonna restore this vice and find that Abom79 logo.

Matt at Diesel Creek has just installed one of these vices.

I love how you can hear the machine adjust RPM to maintain an ideal linear speed for the cutting tool at different radii throughout the operation. For all its complexity and strangeness when coming from manual machining, computers can do some amazing stuff.

I do that kind of parts daily and make my own program. I can do that without scraping any part. But I have been doing it for thirty years we have OKUMA machines. You stick with it you will get better. You have all the machining knowledge. One of my tricks is to back off tools and measure then restart program.

Fireball Hard Tail Vice ULTIMATE EDITION!

When I first started watching your channel I never thought I would see the day where you would be using things like Fusion360 and having CNC machines. I have really enjoyed your new journey into CNC machining :-)

The most accurate vise since middle ages. I would not be surprised if it can clamp a single hair safely at the end.

I like the sound of the lathe spinning up when the diameter narrows.

Good to see your progress on the CNC equipment. Your confidence is growing with your knowledge. Also encouraging to see your developing skills in Fusion 360.

It's always amazing to watch the problem solving. You just work it out in your head, teaching yourself some new things and away you go!

To stop the stock push back in the chuck, get yourself a deflection beam torque wrench. For my 3 jaw chuck, I find 80 foot pounds holds great for heavy roughing operations.

I agree with the guy below about tool length we always have to shorten our tools.

Loving it. Making an individual part on the CNC is time consuming, and uses a lot of practice material, however if you were to then go into production on the part, and knock out hundreds of the things, the time and effort would be worth it. I used to knock out 'shear pins' for one of our plant during the quiet periods - and the nature of the plant meant they would pop them on a regular basis. If CNC existed back then (well it didn't in our shop), I could have produced 100s of shear pins in the time it took me to make 10s manually - and that was a really simple part.

Obviously this is you learning to CAD/CAM and CNC where any project is good, but this shows why one off parts are almost always quicker on a manual machine with a skilled machinist. If you're making multiple parts CNC is king. Happy new year!

So, part it off leaving about 1 mm stock that will prevent the part from falling. Then break it off after the lathe stops.

Good to see some more complex parts coming off the CNC. I see a lot of time goes in to the setup and trials. Thank you for the video.

Thanks for doing this series, its great!

Great video showing the steps and struggles

If you turn on optional stop you can check part before next tool and fix it before you cut.

I own 3 older milltronics. It is amazing how similar the programing is from 25 years ago on these. Very intuitive conversational programing

Another great video, thanks again for your time and efforts after another year of sharing your life with us. Always got people that think they know it all or don’t like how and why you’re doing things, but you have been the same since the beginning and we all appreciate it. Take care and Happy New Year!!

I have been enjoying the series. Keep em coming.

Thank you!

Enjoyed watching - Thanks

Fusion 360 once mastered (and it's not a difficult one to learn step by step)... is a great program.

its nice seeing you being open with learning a new skill. we all have our learning curves and its nice of you to share. most here know you are a accomplished machinist and understand where you're coming from. 👌🙋‍♂️

Great job. Thank you 😊

Awesome video. Thanks for sharing.

Another EPIC video to end off the year with, these never fail to teach you something new! keep up the awesome work and Adam, I hope you have an AWESOME 2024!

Thanks for sharing.

You are a Master. No doubting that.

Awesome video, again.

Nice to see how well you are doing with the fusion 360 and programming your Milltronics machines! Its definitely an adjustment from going from pretty much all manual work to CNC work. Keep up the good work man!

Fun for this former design/development engineer to see CNC lathe work up close. I was only allowed to look through doors of the machines making my designs. The sound of the spindle speed automatically keeping surface speed constant, and realizing that the spindle is going the other direction and the cutting tools are "upside down" was great. I did not think that I would watch the entire video, as I have no interest in adding CNC to my basic shop, but I enjoyed the entire video.

I think it was Haas who made a video where they measure how spindle speed affects chuck gripping force. It was more than I expected. You might be able to reduce the push-back problem by spinning slower.

Good stuff. I am learning Fusion 360 lathe programming as well right now so thanks for showing some of the details that you went through learning it. It was helpful.

Maybe you can get the contract making those parts for Jason. 🙂

Consider rerunning the finish pass over the od of the thread, and then re running the finishing pass of the thread. Should eliminate the need for filing.

Thank you Adam love watching your videos happy new year to you and Abby watching from South Africa

Like you, I am also still learning how to operate my small woodworking CNC. (I am retired and now a home hobbyist.) My butt still takes a bite out of my seat every time I run a new program I have written. A crash would be disastrous. I always make an "air cut" before committing to my part. I hope I get more confidence with time. Thanks.

It is fantastic to see you continue up the learning curves of driving CAD/CAM and CNC. I love the manual Machining processes you depict so well, the touch of modernized Machining is great though, so many cnc channels on RU-vid make it look relatively easy, the basics of cnc work are not easy to master.

That shore is purdy.🤠

Good information thanks for sharing

I recently saw a video on the issue of chuck chatter & chuck holding strength (pushback) made by Robrenz titled "LATHE CHUCK MAGIC TRT#5" It's a very interesting video and perhaps some of the information in it could help with these issues. I have been enjoying the series of this vice build & can't wait to see it fully finished & assembled.

Iearingis aimed thing we all go thru, videos as well as matching. Thank you.

I love to see you showing us your way of learning. I can deal with fusion360 quite easily, but don't know if it'd work on a cnc. But I've been dealing with computers since the '85. I still think the manual turning is way more "cool". I find computers boring. But a human that can make parts with

I never thought I'd see you getting comfortable using Fusion 360 and a CNC machine. However, I like it! I've been learning Fusion 360 for 3D printing. It's a handful but it is so gratifying when you ultimately just pump out a design and then the g-code without struggling.

Very enjoyable video,Adam.Happy new year.Thank you.

I love cnc lathe,

4140, steel of the Gods!

Maybe a nice tip: turn the solidbodies off when simulating. This will insure you have a good representation of the cuts it will make.

Nice job Adam and Have a Happy Prosperous New Year for You and Yours.

Your cnc adventures are working out pretty well. Maybe you could work a deal out with Jason for some American parts for his Made in USA vise

very nice

Kevin is a real ninja when it comes to CAM in F360, you couldn't ask for a better instructor....I'm getting a kick out of seeing you making the transition to CAD/CAM.

Adam have a Happy, Prosperous, and Productive New Year🎉

Glad to see you embracing the world of CNC and fusion 360. You only have eight passes on your threading cycle. I can hear it’s really cutting chips hard. I would change that to 20 passes. You’re not trying to run production here you’re trying to make a good part. Great video enjoy the series. when I thread, I make the diameter of the thread, .005 less than nominal size. this will save you on filing.

Fabulous. ...... & Happy New Year !

it's worth it to get good at CNC! Good for you and keep going!

Nice

We see a lot of personal projects now on this channel, which is great, but what is he working on for his 9-5 (if anything at all)? He used to show stuff like that at motion but not anymore. Miss that kinda content.

Give Carmex BXC threading inserts a try... They're by far my favorite

G'day Adam Another great video, with all the bits & piece looking reasonably good, and fitting nicely into the base area Keep up the good work, catch you on the next one. Have a Great & Prosperous New Year 2024🎉😊

Your pushback problem might be related to Max spindle RPM for the Chuck. Maybe limiting the RPM might help.

Хорошее видео. Желаю крепкого здоровья и счастья в новом году!)

This lathe chuck bison bial from the Poland is an old company dating back to the times of communism in the old days, 70 percent of their production went abroad, a lot to the USA. Another company that sold to the American market was Poreba, a company producing heavy conventional lathes.

Adam, I might suggest that you get a torque wrench to use on the chuck instead of the "T" handle, and tighten all three scrolls to a set torque which you will have to determine with some testing.

I don't know who Fireball Tools is having machine this part for them but they definitely out to talk to you! Beautiful work!

Nice video Adam 😊 i see that learning cnc is really an experience. I have a job shop, working on our own equipment, so i only have manual machines. I like that content, cant wait for the next video, thx Adam 😀

A 2 1/2’ shop vac crevis attachment works good to catch parts during cut off.

Adam, Been watching your channel for years. Listening to the sound of your cold rolled vs the turned 4140 tells me that the cold rolled bar wasn't really round as we all know. Your 6 jaw is more sensitive to chucking on diameters that are not truly round. I've been making round stuff and getting paid for it for almost 50 years and am 2 weeks shy of retirement. Sometimes the boss says turning something to grip on isn't needed, then you show him the difference between his way....

So After all the troubleshooting you did getting things dialed in, the material doesn’t fit in the chuck 😬 man I appreciate your patience and willingness to broaden your horizons. I may have wound up finishing the bolt manually then smashing the cnc with a sledge 😂

........G'day Adam. nice work mate. Cheers, Malcolm.

Now that you have the program setup, offer to make a lot of them and sell them back to Fireball Tool.

Hi there Adam, your cnc turning ops are good, however, the threading operation, your cuts are too heavy. I could hear it quite clearly, maybe lighten the pass depth, for and accurate and great looking thread. Keep it up!

Since the vise has a 5/8-11 thread tapped in the bottom you can put the whole thing on your angle grinder and really put that vise to work.

Turned parts look good, however it sounds a little heavy on screw cutting. I don’t know what options you have available with your lathe and/or cad software but decreasing depth is a great function. I will often take cuts from 0.25 down to 0.01mm, especially on one off parts where cycle time doesn’t really matter.

Try moving that threading tool back in, I never ever had my threading tools hanging out that far, we used to thread free machining brass at 3,000 rpm and get perfect threads every time, I do appreciate you are working with a much harder material.

Viewers might enjoy seeing you broaching the allen in the vice screw.

Hi Adam always fun to watch videos from you. here is a tip that may help. You have too much protrusion of your tools. your tools should be as close to the turret as possible, to be as rigid as possible. if you don't have room to reduce the tool protrusion, I would cut off part of the tool holder to have less protrusion on the tools. You will solve a lot of problems with it and you will get better results. Also use a torque wrench for the chuck, so that you better learn how much torque you need, and get more stable results between the parts.

nice LG monitor!!

Hi. There is very nice film. And its very nice to see you got "MADE IN POLAND" lathe chuck... :)) Very good job. Happyy new year !

Like butter

Great work, Adam! You not only have some parts that will please your customer, but you also have a program that is potentially a valuable piece of intellectual property for your shop. I earned a living as a software engineer since the late 1960's. The basic principles of modularity, testing, consistent naming of variables, and clear documentation really haven't changed that much since the beginning. It took a while to get the field going, but these principles hold for all engineering, not just writing software. Please tell us why the Fusion360 cutter went red when you simulated cutting the groove at the end of the thread. I suspect that it was noticing that the ball mill was being asked to plunge into a sloping surface. Just a guess on my part, but it would be fun to know. There are two manual operations that perhaps you could automate. First, could you just put the stock in without measuring by hand and then have a Renishaw touch probe find the length? Your program could stop and declare an error if the length was way off. After the end is faced (with minimal machining), the probe could be used again to test for shifting of the part in the chuck. The second is your use of the file to clean off the tops of the threads. I can think of several ways to ensure clean thread tops automatically.

I don't know a whole lot about machining, but I figured I would pose a hypothesis on the slippage or push-back you're experiencing and how to fix it. I don't know what type of coolant you're using, but I'm guessing it's an oil/water mix, and that's what's causing the slippage. I would do a more thorough drying of the chuck jaws interface faces with a clean rag, and if your flipping the stock, wipe that down too. Maybe you already do that and don't show it, I don't know, just figured I would throw it out there and see if it helps. Thanks for sharing what you do and how you do it. YT wouldn't be the same without you.

Hi Adam... noy only you can make a batch of those things in an hour...but you can also be attending another job while the cnc makes its magic.

Boomm

I use Solidworks for my main design work and I use Fusion 360 for my CNC flat bed router

You may have opened up Pandora's Box. Everyone will want your version!

Hi Adam, I've been watching your channel for years, I really appreciate all of the educational content you've put out. One suggestion, you might want to check out a spacemouse if you're going to be using fusion regularly. It takes a little getting used to, but once you have it down it makes using CAD so much faster and more enjoyable. I don't do it day in and day out so don't find a need for the more expensive ones with all the programmable buttons, and I think the cheap ones are only like $100 so it's not bad.

Nice……. Never thought of the idea there is a difference between the 6 jaw and the 3 jaw on how it grips something that might not be round….. interesting. 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼

I've learned to get rid of burrs on threads is to rerun your finish turn and rerun your thread in the program (P00000 for fanuc)

Adam, you could use the CNC to engrave your logo in the vise (even unseen if you prefer). Could be cool, and also makes your example the special one.

Your a brave man parting a big lump of stainless off like that lol

Wondering if Jason will ask you to make a batch of the pins for his first batch of US vises. You are just about ready to make a priduction run.

4140 ground stock will push back in scroll 3 jaw . If you feed more then 0.25mm ( like 10thou) . Have that same problem
