Milltronics service and training technician Steve came down to the shop for a few days to help train me using their Milltronics 9000 CNC controllers. The Milltronics CNC control is straightforward and easy-to-use. Whether you choose Conversational programming, industry standard G&M code or use a CAD/CAM system, the 9000 CNC gives you the flexibility to use the most efficient program for each part. We’ll start out on the ML16II cnc lathe to get the hang of the basic controls and functions used for turning operations.
I will be hanging out with Milltronics at IMTS September 13th from 10am-2pm. They will be located at Booth 338319, South Building, Level 3.

Looks like some nice machines. I would suggest that you get left hand lathe tooling as you tool up, that way the forces are pushing down into the cross slide and saddle instead of trying to lift it up.
i know nothing of cnc but this small intro does not show any justification for all the money spent on cnc jmho
Cool ?

Adam, Under what circumstances would you utilize a high speed 3400 rpm? And how does it affect surface finish?
Wow Adam my frend, what a speed in that Milltronics Lathe, beautiful machines in the shop….
The one thing you have to understand the moving the X & Z axes in the minus direction is always toward the part. Also, you need if the controls move the tool 1/2 for one or two for one on the X axis. By what I mean is if you move the X offset .001 if if the machine cuts .001 or .002 off the o.d. of the part. You should be flooding you part with coolant. You ALWAYS NEED TO SET YOUR X & Z axes with a plastic or steel shim & adjust the offset according on the controls. We always made our tool sets with .030 plastic shim stock on almost every item. We made aircraft rotating engine parts, so we were holding +/- .0005 or .001 tolerances. When cutting threads, we measured the gauge cut with a pitch & diameter gauges & adjusted the X & Z axis as needed.
Fusion 360 is the worst program to use to draw up parts & machine with because Fusion 360 will machine parts the way it wants to instead of how the part should be machined. Just like manual machining, with Fusion 360 you will have to move lines of code around to produce the part in the correct sequence of operations with the correct speeds & feeds.. For the most part, whatever material & insert you are using, using the CSS (Constant Surface Speed) will work well. If the material is more than .050 – .100 out of round you will have to decide on using a carbide insert with flood coolant or a ceramic insert without coolant. Either will work well enough so you can go back & re-run the item number with a new edge or insert.
I can't count the amount of people who use Fusion 360 & the manufacturers controls when they should have bought a high level programming software & Fanuc controls.
Thread cutting… a mechanical or math sync to get feed correct? Never used one of these machines before.

Nice jump to cnc world.
I came from a background or Ward lathes with mechanical adjustments. The setup times were terrible. Trial cuts test then take another cut to get it right. Once a cnc turning centre was purchased it was so accurate and set up times dropped dramtically. I even made some jigs and fixture on the cnc lathe. It was so accurate with a 12 station turret too. I like the newer style turret loading where a magazine of tools are on a conveyer up to 100 tools. Once loaded and set up you dont have to swap and change tools around so much like a 12 station turret. The machine brings the next tool into position for the next tool change after indexing.
Adam, when debugging a new program….. Put the machine in "step mode" and cut your rapid traverse down to about 25%. (And at all times keep your hand near the chicken switch!)
Cut air for the first cycle, making sure that all the tool moves look correct to your eye. If a tool offset is noticeably wrong, or the machine pulls up the wrong tool, or the path geometry does not look right…… It's best to do it in air…… First! You can avoid a lot of crashes that way. (….. from an old programmer)

Those machines are impressive! I'm thinking that they can really multiply the productivity of a small shop like Adam's, allowing bigger jobs to be tackled.
You're going to love it Adam.I was a manual machinist most of my life and purchased my first cnc lathe 11 years ago and a couple of machining centres down the track and it was the best move I ever made even though I still do lot of manual machining as well but can't compare the speed and finish of a cnc.I remember you machining some fiddly small parts in some early videos that was time consuming now you can do it in fraction of the time.I use conversational programming on the lathe but gets too hard on the mill especially 2.5-3 D machining so subscribe to FUSION 360 which is cheap and makes life so much easy.
That was a major new experience.
So your thread PD is a couple thou over. You made your tool wear adjustment, why didn't you just rerun the threading cycle instead of giving up on the part?
Maybe it's just me, I found Adam's channel a couple years ago and have learned a lot and enjoyed watching the turning and milling ops. His workshop is 10 times better than mine but I could identify with it. All this new CNC stuff is obviously marvelous and the way forward, but probably like many on here it's absolutely beyond my wallet and will remain so unless I win the lottery. I'm beginning to wonder if there's a change to the target audience, I find myself less able to identify with the newer videos – let's face it, there's hundreds of CNC related videos on you tube, but not so many using the traditional techniques than ordinary folk can copy and learn so much due to Adam's ability to impart knowledge.
Tôi có thể học hỏi ah rất nhiều ah có thể chỉ dạy thêm được ko
You have a cnc now. That thread should go turn/chamfer – relief – thread – turn over thread – chase thread. Far less burrs, and you can do a measurement between your turn and final chase cycle. I run thousands of parts with this formula and only have burrs when the tool breaks down.
Are you going to need a hole in the wall for long shaft work like Keith Fenner's old shop?
Is the HEADSTOCK ! Moving Around ! Or Something !?? HORRIBLE ! VIDEO ! This ! And Bluntl Tools ! Sounds LOUSY ! TOO !!
That's some exciting stuff Adam, little jealous if I'm honest, but super happy for you and can't wait to see all the new CNC content!
Awesome to see you on cncs
Proud to see a Made in India part on the American machine.
Just seems odd for the lathe to be running backwards.
Oh boy Joe Pie is not going to like the way that is programed to cut those threads ! Remember he constantly says you should never cut threads from the outside going to the relief but the relief going to the end of the threads. Shame Shame Shame LOL
First thing I see … you don't have a coolant setup on the lathe?
& who says you can’t teach an old dog new tricks! It’s really going to be awesome to see you learning all this stuff
Can you cut a simple cam shaft?
Wonder why no way covers on that thing?
robots are cool.
those are some awesome machines! I bet you will have some shorter videos now! 😀 How is your live center holding up the that RPM?
A bit of coolant wouldn't go amiss Adam. You're in control still. The slight change is that you are instructing the machine to wind the handles for you. Good luck. This is another exciting side to engineering.
