Mazak Lathe OD Threading Mazatrol. Here's a short video about OD threading on a sample part. I also show you the different methods to re-run a thread to dial in the size.
Warning! I forgot to mention in the video but DO NOT change the speed on the override or in the program during or after the machine has cut the part on these older controls. The machine will loose the thread lead if you alter the speed and it WILL scrap your part. BTDT. Only make changes to the spindle speed after you get the part off the machine.
This is the first youtube channel I have subscribed to. I am just blown away with how well you explain everything. We have a T2 Mazak so your videos will help train our newbies. Thankyou very much.
Lower numbers are rougher feed rate and higher numbers are finer feed rate. Number 7 finish is slightly better than a 32 rms finish. It feeds a .031R insert at .0039" IPR.
Tip: At 10:35 where you can set the next line to thread i an taper, If you rewrite the same stop point again eg: FPT-X =3 FPT-Z=1.8 the machine transit in a smoother motion at the end of the thread and not doing the sudden stop motion. Works on newer machines don't know about this machine.
Nice videos Phil. Fully informative. Thanks. I m a Mazak turning machine operator. new comer to Mazak from Fanuc Using Slant Turn 600 Smooth G. I hav not seen tool shape in simulation . Only path graph we r using till now. Is there any Idea to have tool shape also in simulation as you r using.?
It was nice video, very informative, and successfully delivery all the information to make an OD thread on the mazak. Hey, do you know how to chase the thread on the mazak lathe? Thank you.
This machine uses offset columns like a grid. Offset column number 1 or the second offset column 2. Go to 18.34 in the video. You can see the two offset columns there.
Thanks for the awesome videos. I am trying to make internal threading toolpath for which the tool should retract to X21mm and then come out of the hole. But in actual, it first retracts to a smaller number i.e. X17.3mm and then go to X21 and then come out of the hole. X17.3 will cause my threading bar to smash in to workpiece. Do you have any idea what could be wrong and how it can be avoided? Would appreciate that. Cheers.
Great video. I run a Nexus 350 II. Threading isn't my most fun thing to do. We have added the speed override option which works great for modifying speed during the thread cycle. The only thing I never figured out is the touch off of the tool on the tool eye vs the offsets. They are never theoretically zero on the X axis like a correct turing tool at the finish. They are always way negative on the OD or way positive on the ID from zero when threading only. I use .86603 x pitch for my thread height. I can get good threads but just can't trust to go to size or close off the tool eye. Also do you have any videos of how to chase threads for repairing if loaded back in the machine. Ours has that capability but nothing in the book to truly describe how to do it. Thanks for your videos. Older machine but the concept is the same.
@@brianmatias471 yes it does I believe. I have not tried it yet since we purchased the machine about 4 years ago. Haven't needed it yet but would like to figure that feature out.
@mazatroltipsandtricks6816 mazatrol t32-2.I've just started using Mazak, I'm taking examples from your videos, but I'm still at the beginning and I'm a novice, thank you also for your answer.
how do you remove the burr at the beginning of the thread? Are there special solutions in Mazatrol? In TCP? Thanks for the reform option and other useful information.
@@mazatroltipsandtricks6816 Hey Just thought I'd pop back in here and share what I found, if you want to thread clip a UNC thread it can be done by running a threading cycle with a start point a half pitch farther out than your original threading cycle, and ending at a full pitch in! keep your exit angle at 60 degrees and your grooving tool should have it clipped!
Not sure if you will see this since it an old video. Do you have anything that explains how to add a thread relief, specifically for my situation when the thread relief is against a wall. Thanks.
I have not made a video regarding a thread relief even though I do them all the time. I did a grooving thread relief on my ID threading video. For OD threads, I usually use a VNMG 332 insert tool and program a relief groove at a 45 degree angle behind the thread.
Hi, Mr. Phil thanks a lot for your video! At the end of the video Could you please explain why are the tool offset-X 0.005 and 0.001? How do you know it, sir?
Is the length value the total length of the raw stock (including what is clamped in the chuck)? Or is it just the visible stock protruding from the chuck jaws?
Tomasz Spiszak awesome thanks. One last thing. What about the inside diameter values. If I have a raw solid stock and I am to bore a hole say 6inches as per drawing. Do I then insert this value of 6 in the ID value field?
Same procedure as right handed thread. You just install a left handed tool in the turret and set the chuck direction to left hand. The threading program will be the same.
Would like to see some videos of a 40n t plus that’s what I have and all we cut is a36 anywhere from a 16x2.5 inch blank making casters to threading an 1.25 axel bolt😂
Hello Phil, I can write the program as you showed, it works in simulation, but when I run the machine, it gives error code 635 ACCELERATION DISTANCE EXCEED. What could be the reason? Best regards
@@mazatroltipsandtricks6816mazatrol t32-2.I've just started using Mazak, I'm taking examples from your videos, but I'm still at the beginning and I'm a novice, thank you also for your answer.
What controller do you have? I only have parameter information regarding the T-2 and T-3 controls. For the threading parameter, U35 controls the acceleration distance. It is set to a low value from the factory and that causes problems with threading at high RPM speed. The range of the parameter is 0-255, but I have mine set to 100 and it works fine. Other option is to slow down the threading SFM value in the program.
@@mazatroltipsandtricks6816 I mean taking away the first imperfect thread with a grooving tool. For example on a 8 stub acme thread and using a grooving insert that's 0.125 to remove the first imperfect thread. I've also heard it being called a higbee thread too

you should've shown how to do a spring pass cause that's what you need right?? just clean it up
@@derick3482 I didn't think about it at the time, but yeah easy to do on Mazatrol.
Thanks sir
@@christophercolumbus8944 The way Mazatrol works is you need to have a minimum of 3 passes in the threading line.
Thanks for your time. You save me time by not digging though 20 year old manuals! Thanks again.
You're welcome.
Phil, I am just starting with Mazatrol Programming and I am learning a lot from you. Thanks
Glad to hear its helpful.
Thanks for the quality video, you cleared up some finer points for me.
Cool. Thanks for the compliment.

Thanks for the positive feedback!
what control do you have? do you use EIA a lot?
Excellent video.
I like that you got closer to the Nazak screen so I can see better.
Thanks
Thank you sir. I found this very helpful 👍
Glad to hear it.
i like that single process option
pretty clever
Thank you teacher
You're welcome.
Phil, can you do rethreading, if need to rework the workpiece that already took out of the chuck?
Teşekkürler.

Hey man, nice video again, coule you explain the surface roughness or make a video about the diffrance?
Lower numbers are rougher feed rate and higher numbers are finer feed rate. Number 7 finish is slightly better than a 32 rms finish. It feeds a .031R insert at .0039" IPR.

Using Slant Turn 600 Smooth G.
I hav not seen tool shape in simulation . Only path graph we r using till now. Is there any Idea to have tool shape also in simulation as you r using.?
Unfortunately, Mazak took away that feature in the later controls. You have to do a simulation to see the tool now.
Very good teaching 👍, congrats 👌 👏
Thanks for the compliment.
It was nice video, very informative, and successfully delivery all the information to make an OD thread on the mazak. Hey, do you know how to chase the thread on the mazak lathe? Thank you.
Trying to pick up an existing thread is very difficult. Newer Mazaks have an option to make that easier. I've never tried it myself.
coming from a fanuc background why are your tool offsets all 1 instead of t0101,t0202,t0404 etc?cheers.
This machine uses offset columns like a grid. Offset column number 1 or the second offset column 2. Go to 18.34 in the video. You can see the two offset columns there.
Hi! and thanks for your mazatrol school service! How do you thread an acme screw? ex screw elevator, "threading incremental i Z" ?
ACME threads just need more threading passes but the program is the same otherwise.
Phil I’m picking up a quick turn t6 with mazatrol T plus control . Is this control similar to what you demonstrate ?
Yes. Anything I am showing will work on the T+
Thanks for the awesome videos. I am trying to make internal threading toolpath for which the tool should retract to X21mm and then come out of the hole. But in actual, it first retracts to a smaller number i.e. X17.3mm and then go to X21 and then come out of the hole. X17.3 will cause my threading bar to smash in to workpiece. Do you have any idea what could be wrong and how it can be avoided? Would appreciate that. Cheers.
On the T-2 and T-3 controls, you need to put PNo0 line ID size same as the minor diameter of the thread. Check out my ID threading video.

Our Integrex has the feature to pick up a thread but I have never tried it out yet. Old machines like my 10N doesn't have that ability.
Jim Monk Does your machine come equipped with the Thread Position Teach option?
@@brianmatias471 yes it does I believe. I have not tried it yet since we purchased the machine about 4 years ago. Haven't needed it yet but would like to figure that feature out.
@@brianmatias471 I don't remember if it was included as a standard option or if it was extra for the Integrex.

You can remove the burr by rerunning the finish pass of the turning operation after the thread is cut.
Hey Phil Thanks for all you videos they've been a big help,
Do you have any tips on Thread clipping in Mazatrol?
I've never attempted it. I'm sure it can be done with a groove tool running a short threading process.

I’ll try that, thank you
Important question,If I don't finish threads at end of shift and power the machine off,will it know where to pick up the next day?
I honestly do not know. You may want to run a test part on your machine to find out for yourself.
Hi, Mr. Phil thanks a lot for your video! At the end of the video Could you please explain why are the tool offset-X 0.005 and 0.001? How do you know it, sir?
The offsets were just examples. You will need to adjust your offsets accordingly to what your part measures.
@@mazatroltipsandtricks6816
Yes, I got it, thank you so much for the helpful videos. Hope you're still doing well during this pandemic time
Is the length value the total length of the raw stock (including what is clamped in the chuck)?
Or is it just the visible stock protruding from the chuck jaws?
Raw material, plus I always add some more mm.
Tomasz Spiszak thanks. So the length is the raw stock the entire raw stock. This includes what is clamped and visible ?
@@75kGa yes.
Tomasz Spiszak awesome thanks. One last thing. What about the inside diameter values. If I have a raw solid stock and I am to bore a hole say 6inches as per drawing. Do I then insert this value of 6 in the ID value field?
@@75kGa put 0 in the first line for stock min dia. Check out his 1st or second video , there's a great explanation.
We have to threading OD on 4 mt pipe so please suggest
Not sure what you mean.
I need to turn a 1-8 left hand thread. Never have done it, I can't find any information on it. Any help is greatly appreciated.
Same procedure as right handed thread. You just install a left handed tool in the turret and set the chuck direction to left hand. The threading program will be the same.
@@mazatroltipsandtricks6816 I'm guessing it needs a left hand insert holder?
A colleague said I could use a right hand and start into the part, 5 inches in this case. And thread back to the front. Will this work?
@@robertzacharias6567 Mazatrol does not play well with that method. Get a left hand tool.
Would like to see some videos of a 40n t plus that’s what I have and all we cut is a36 anywhere from a 16x2.5 inch blank making casters to threading an 1.25 axel bolt😂
I do not have a T+ controller.

Can u show us how npt is program on mazaktrol and threading option ??. Thanks
Ok. Thanks for the suggestion.
Hello Phil, I can write the program as you showed, it works in simulation, but when I run the machine, it gives error code 635 ACCELERATION DISTANCE EXCEED. What could be the reason? Best regards
What control is on the machine? You can slow down the cutting speed to get it to work or change a threading parameter.
