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.
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.
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.?
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.
@@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.
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.
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.
@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.
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.
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.
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?
Hi, have you any experience with tracing/ picking up existing threads for reworking? I've been led to believe that it is possible on the T series controllers??? I know it's possible on later controller, would be super handy if it can be done on T series
@@kevmarriott6272 extreme pain in the ass to do it. Very risky operation because it's an eyeball job trying to line up the moving tool to the thread. Not recommended.
Hi Phil, i need to make ID oil grooves in a bush, been trying using the ID threading option after 30 mm pitch it doesn't look correct on the display Can the T2 manage this? any advice would be greatly appreciated Thanks
@@miguelneves3982 the display will look funky with an extremely coarse thread but it will work. Be sure to have PN0 0 line ID min set to the bore diameter of the hole otherwise the machine will retract X to 0 on last pass and possibly crash the grooving tool into the other side of the part.
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

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?
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.
@@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
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.
using Mazatrol T32-2 I cut right and left-hand threads M50x1.5 with same tool & insert, just change Z start and finish points (swap them over) you do need to allow for approach/acceleration distance for the left-hand thread
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.
