Hi Moto Fix. The only issue that you may run across with your SMT (or any machine with a Fanuc control): When you change the speed on a Fanuc control, you'll lose the lead reference, the machine threads from a different starting point. That is the magic of the Haas lathe. I can change the speed, not lose the lead, I can set the Z reference when the spindle is at the M19 spindle orient position (because we always thread from that point). Best of luck to you!
Yep, Me too, LOL. Awesome reply. I often revert to the second method (production recuts, with Txxx and M19) because then I'm using proven G-Code, actual axis values, and I'm driving the ship, instead of "Cycle Start and hope I answered the questions correctly.
M19 will always make it end up at the same position in the thread, no matter what rotation the piece have when u set it in the chuck? im getting confused now ;)
Hi Darren, good info, did not know we could alter the Z and/or X offsets to get the threads dialed in after we start.THANKS! Also, for multi starts threads I guess it would require a custom program?
Hi Michael. Glad to help. For multi-start, you have a few different ways you could handle this. One option would be to treat this as "two separate thread-recuts". However, what I would do, is make this MDI program become a saved program in memory. I would then duplicate the G76 threading cycle a second time, and add "Q0" to the first G76 cycle, and "Q180000" to the 2nd cycle (example for a 2-start threading cycle). This would cause the first cycle to run at 0 degrees, and the 2nd to run at 180 degrees from zero. I hope you've had a great week.
Do you have to start the program in the thread?? I don’t love that and don’t see why it can’t just ref that point. Seems like a crash waiting to happen. Especially since Feed hold is usually disabled in thread cycles.
Hi Shawn. This depends on which method we are talking about. If you are using the VPS cycle, you will always leave the tool in the part. The program will pull out in X, move over in Z, and start the cycle for you. If you are using the M19 / Set G54 method, you are welcome to pull out of the thread manually before starting. Thank you for watching.
How deep do you set the ref point? Do you stick the point of the tool down in the root of the thread. How does the program generated know at what depth is the final pass. Does it just basically go to depth it was set at.. and then you adjust the X - accordingly? Also I don’t see why adjusting the z is rare. I would think that would be one of the main tools. To skim cut and if it is hitting only one side of the thread to back off the z to center it better? I guess it depends how shallow the original threads are. If u need to cut a significant amount deeper then it will likely clean up both sides either way with a eye up ref point. If it is close similar to chasing in a manual u can blue up threads and if it is hitting on one side adjustments can be made before cutting deeper on next pass. I guess it would make more sense to me if it just did one pass where it is set in the x and the. Simply adjust x neg and re run deeper. Adjusting Z if needed to align better.
The machine will use the location in X that you started from (the main reason for keeping the tool down in the lead when pressing cycle start. It will then thread deeper by the amount that you specify. Remember that it is not necessary to get this value "100% perfect" on the first try. You can change the X-value or Z-value in the "G20 L20 P99" line and run the thread program multiple times, without having to set the reference over and over again (see 7:40 in the video). Thanks again.
Hi Christian. That area is actually outside of our South Texas territory. The guys at HFO Dallas may be interested in giving you an estimate. Due to the number of machines in our territory, we also do not typically get involved in programming and turn-keys. I have a few friends in the business that have great rates and service. David Vagi ((713) 269-3037) and Mitchel Hawkins ((713) 876-8516) are two guys you may want to call. Thank you for reaching out.
In short, every Haas lathe threads from the "Zero position of the chuck". When commanding M19, you are sending the spindle to the "Zero position of the chuck". When lining up the threading tool, into the thread groove, and then setting that as "G54 Z0, for example", you are synchronizing the Z-work shift, with the Zero Position of the chuck, which allowing you to run a standard program / cycle, and cut the thread. Now.... When you line up in the "2nd thread back", you have just set G54 Z0 about 1/4" negative of the face. This is how you would "push back" the connection, by re-facing it, turning the shoulder back, and rethreading (most popular way to repair a badly damaged oilfield connection). If you do not want to "push the thread back", you would need to make a positive work shift by 1 thread, 2 threads, or 3 threads (depending on where you dropped the tool into the lead). You MUST make this shift in thread-lead increments to remain in lead with the thread. Hope this helps. Simple as Pie / Hard to explain, LOL.
@@Darren_HFO_Champions tnx .. I understand better what is happening now... I managed to repair some fine metric threads that got dented by using information in this video. :)
Hi Darren, thank you for coming out to Air center and working with us. It was very informative and I just wanted to say thank you.
Hi Richard. You are very welcome. Dan and I enjoyed the visit. Training is always like hanging out with friends, :-)
Great video! Very informative!!
About to try this out on the st30. I work at Houston Precision and we get all of out HAAS machines from y’all! Very informative
Thank you Sebastian! Feel free to call our office or email if you have any additional questions. Take care.
Excellent video thank you
Excelente tips Gracias.
This may save my life tomorrow. Although I dont have a haas. I have and SMT. I cant find any decent videos on this topic.

Thanks for the comment. We'll work on more. Anything specific you'd like to learn about?

Hey daren, you used to come to the shop I used to work at in San angelo tx. It Nichols oil tools.
Hey Josh. Sorry for the delay. Yea man. Great to hear from you.
@@Darren_HFO_Champions they just called me back over there since covid hit.
@@joshsantillan6273 . Awesome deal. Feel free to holler with any questions, once you get started there.
How much do you charge to set up and program an ST40 ? Our company is just 20 mins South of Fort Worth not far off I35w

Change settings so the machine doesn't beep with every button push, that beeping drives me crazy. Who wants to listen to that all day lol
interesting, but im completly lost after 9:10 .. make a better explanation ;)
