HTML-код
- Опубликовано: 26 июл 2024
- This video covers a wide array of topics related to using the tailstock on your CNC Turning Center.
Some of the subjects we touch on are: length to diameter ratio, center drilling, choosing a tailstock pressure, dealing with fragile parts, and choosing and maintaining your live center.
We also review the particular methods for commanding and controlling the Haas Tailstock with M-codes and Settings.
We finish up by watching the same part cut with tailstock support and also without support. Watch the video to see which part finishes first.

Thanks Haas, your videos are helping me in my CNC milling and turning class
Pure gold these videos, thanks Haas!
My favorite automation manufacture company.
Thank you once again Haas for making a very informative and easy-to-understand video. I watch your videos all the time. Such a pleasure to watch.
Cheers guys!
Great video, I have a brand new Haas ST30ssy with the Tail Stock and it was super informative even if I have been doing it for 8+ years, just the graphics alone are super great. Thanks
Great video! Just stepping into my career but knowing these information would definitely help a lot!
I love Haas because they show so much for free like Haas School :) thanks
I am new to this CNC stuff.. Recently got employed.. Awesome narration.. Really helped me a lot.. Looking forward for more videos.. Good job guys....
This is exactly why I went from our old fadals and our tormach to Haas for my mills, all this free knowledge (its worth lot to newer machinists like in our shop) now that I need a lathe, I know who I'm going to buy, especially since it looks like the controls are so similar....
"Tormach' sounds like 'torment' to me, LOL. No experience with them but still I wouldn't want one. Currently working with a couple of good old Okumas, love the quality.
Perfect job! Thank you!
Very helpful and informative. Thanks guys.
Thanks for making the tail stock a pain to get a center knocked out of compared to older Haas machines. We just bought a new ST-20 and there are several things that Haas "fixed" that wasn't broken on our 2001 SL-20. For that matter, there are several things on this version of NGC that have been "fixed" that were perfectly fine on 2 year old NGC.
We finally started to use our tailstock on our ST10 at school and this video was fantastic. We wanted to start teaching advanced turning operations and how to set it up. Great job
appreciate the comparison studies!!!! thanks for Speaking with Data
Outstanding videos you guys make! Thanks.
Great video,keep it coming!
Definitely a great video guys. Thanks for the good info, I will share this video right about .... now.
Great video, covered some things I had questions on. Just what I was looking for.
Thanks again Mr. Haas !
An amazing video! Very thankful for all the information shared!! :D please keep going this way. With more information like this we can understand better the process and its importance in order to buy the best tools, machinery necessary and also work Incredibly BETTER :D thanks again! I can't not thanks enough for all the shared information.
Great content guys!!!
As always very good information provided, keep up the good work, thank you!
Really good, knowledgeable video. Thank you for teaching us that are always learning safe machining practices.
This video was SO helpful!
i learned alot in this video as i have been having trouble with my tail stock in a haas st30
Problems with the retract position?
this is what we need,not the bulhshits like bigbrother :) great job guys :) i like these videos, best regards from slovakia :)
Very helpful video thanks a lot
an informative video like this, and you can get free on youtube. awesome. thanks :D
very useful for beginner..
At my cnc turning use manual tailstock systim not automatic. It so easy for operator. 👍👍
A great video from Haas Automation showing and explaining the use and features of the tailstock on their CNC Turning Centers. Haas equipment is used throughout the World making life easier for machinists and bringing quality machined parts on our tables. Lathes and milling machines are used in many areas of manufacturing as essential basic tools, including woodworking, ceramic parts manufacturing, metal and metal alloys shaping and manufacturing, plastics and elastomers machining.....etc. Therefore, anyone interested in manufacturing technologies for fun, hobby, as an entrepreneur or for their career should definitely familiarize himself/herself with lathe and milling machine basics and probably also with other non-conventional techniques such as laser machining, plasma machining, waterjet.....etc. Even if you are not a machinist, but a consumer of machined parts, I strongly recommend learning the basics of machining operations and CNC and manual equipment, so that when you prepare blueprints or want a product to be designed and want to place orders for parts, you know better what is possible and what is not possible. Also, the equipment a machine shop uses is an important contributor to quality, lead time and price. Knowing something about your supplier's equipment inventory can give you an idea about whether that particular supplier is a good fit for your specific parts or not, provided you understand something about available equipment.

Thank you Haas Automation for posting such instructive content about your five star turning centers !
Great Video
So helpful!!!!!
I got a question.
How can I know or check the center of main spindle and center of tailstock at same position?
Thanks Haas
I just gotta ask, why is this in Korean subtitles as well? lol They're really good.
At what point would you be pushing the workpiece through the chuck jaws? I really do not like using the tailstock without a headstock axial stop, ever, tbh. Although it could be tested and applied with the appropriate safety margins.
Great👍👏👏👏😊
On a Mori, to remove the tailstock, there is a large screw at the neck that you turn clockwise and with a few taps with a hammer and wedge it comes out.
Thank youbso much
Question you guys do a video on the g200 index on fly. This would help so much there is not much on line as far as explaining.
What about using a tail stick on plastic parts I had to use the tail stock on a small diameter long delrin part and I had trouble with using low pressure. With low pressure the tail stock would alarm out when trying to find the end of the part. And wouldn’t keep pressure on the part. But high pressure deformed my center. I end up just positioning the center in the center hole and turned the part without constant pressure. The live center didn’t spin I had a good bit of taper and some small chatter but it helped some.
would you turn a shaft with 200psi tailstock when the shaft has no back support in the jaws? i mean would it be pushed into the chuck?
good
I have question ??what kind of live center can I use for lathe ST25 2019
how do you get the tool to engage the end of the part with setting 93 keeping the tool away form the TS?
Great video! Informative as always. If you have a part that is to long to face and center when extended you stub it up for those operations. My question is when you extend the part to support it with the tailstock do you have to indicate the face and/or center of the part before bringing in the tailstock? Or when you support the part with the tailstock does it center itself? Any insight would be greatly appreciated. Thanks.
Branden Brown Great question. Typically, after you've faced and drilled your center hole with the shaft set back in the chuck you can just extend the shaft to its full cutting length and clamp it with the tailstock, without any need for indication. This is because choking up on the shaft to drill the center hole should give you the best "on-center" position. The accuracy with which the center drilled (60 degree center drill) hole gets made determines the shaft's maximum run-out and OD concentricity, when you support it with a live center.
When the shaft is extended and re-clamped it might be clocked differently in the "stuck out" position, or the shaft might have a little bit of a bend in it. But, despite these issues, once the part is spinning you will be cutting true to the rotational axis defined by the tailstock center and spindle center, and your part geometry will be accurate to that central axis.
Except it doesn't work like that in the real world. If you have a bend in the material in the extended position and you force it to align with the tailstock and machine it, once you release the tailstock/spindle clamping the part returns to its relaxed state and now you have an out of tolerance part in your hands.
Is there a minimum operating pressure of the ST20Y tailstock? It seems on our machine that we get a tailstock undershoot alarm when retracting at 100 PSI, but the issue is resolved at 125 PSI. We were not running at a higher PSI due to part pushback, but we plan to solve that issue with a different set of jaws and then increase the tailstock pressure to the recommended 200 PSI.
Kenneth Higley Sorry for the delay Kenneth! There is indeed a recommended operating pressure for the ST-20/30 hydraulic tailstocks. Per the Lathe Operators Manual (pg. 96): "Recommended minimum hydraulic tailstock operating pressure is 120 psi. If hydraulic pressure is set lower than 120 psi, the tailstock may not function reliably."
It sounds like your plan is to make a new set of jaws which will include a locating back face to act as a stop for the part. This plus an increase to 200 psi pressure should prove to be a more reliable method of holding your work piece. Hope this helps. Have a great weekend!
Maximum deflection isn't at the tailstock end, it's at the midpoint
So just ramming the TS into the part with hand jog is the proper way of finding the clamping position?
It specifically says that jogging the tail stock into the part to clamp is NOT the right way to clamp the part. It says to use M21 only to clamp the part.
Great video! For setting 93, the video shows the operator entering the "operator" position into setting 93. Should this not be the "machine" position?
Good catch KB Machinist - We should be looking at the X-axis "Machine Position" when we are checking and choosing our Setting 93 clearance value. In this case all three values were the same, but you should always use the "Machine Position" for this step of the procedure. We will be adding a note in the video to clarify this point. Thanks!
Got it
sir please upload video about st30 machine turret allignment procedures its my request
What about pausing to make sure that the tailstock engages prior to cutting?
Onley hass👍👍👍👍
26:17 you have HAAS use so good SSV
The settings in the video are different in our newgen control st20
I've never figured out how to handle jog the tailstock although I've done it by accident before I just need to know how to do it on purpose.
What if I don’t want a center drill hole in the end of my part when the part is completed? Teach people about a spud on the end.
I want full training regarding to Haas control lathe in Chennai, including operation, settings, and programming. May you assist me through your certified trainer, please?
heres a video of the unloading of the machines a few weeks ago MLS Machines Part 2
5:45 same as using 60 insert for 55 threads lol or wise versa lol
Great Video. I wish me Translate to German
Hi Ivan Rosbach - Thanks for the compliment. We're glad you like the video. Be sure to subscribe to Haas Automation Europe's RUclips channel; they will post translated versions of the video soon! Find them by visiting ruclips.net/user/haasautomationEU.
I don't know about the newer lathes but my old 2007 SL30's tailstock has been useless since day one.
Where is the setting105/106/107 video?
1:34 propably not or sure it will need. if you clamb it so far you sure want cut diameter smaller. so your L:D ratio come higher. unledd yo sharpen pencil you fine :)
3:57 is 140mm D and 500mm AND longer from jaws too long to face and drill. tell my boss :) is it matter if only drill center with other machine that not even centre both ends and then use them cut part.. first side propably go ok. but next side centrehole not anymore center for surface we just cut and use soft saw to hold them. tell my boss :)
can I have a Haas unit? :D
Can i See french video??? Please!!!!!
En castellano me gustaría más, poner opciones de idiomas
5:50 I'm no mathematician, but that line looks a little bigger than 60 degrees lol
what happens when you hit a scenario where M21 causes a tailstock undershoot alarm, but the foot pedal engages fine?
Hola, yo también tuve problemas con la tailstock , cada ves que leía m22 decia "contrapunto corto". el parámetro 293 estaba en "1000" y lo cambie a "300". Y por el momento está solucionado
I cant seem to find videos that apply to the TL lathes so little of this information in this 30min video is useful to TL users...
BUT ALWAYS M22 AFTER M05 !!!!!!!!!!!!
400 psi says nothing about the pressure on the part
it is hydraulik pressure
on the piston,,,,, 200 psi on a 150mm piston is not the same as 200 psi on a 200mm piston ..
Correct! You need to look at the chart that is on the machine to know how much force is applied.
Im confused, you say 0.00055 inches is "Five tenths"... surely a tenth of an inch is 2.54mm, and five of those is way more than 0.00055 inches! Imperial is so confusing! How can seomthign called five tenths not actually be five tenths of your base unit! Im so glad we use metric here...
It's machinist parlance, in USA and Canada at least. When discussing tolerances in the imperial system at least, we say "5 thou" ou "5 thousands" referring to 5 thousands of an inch (.13mm). Some people will even omit the "thousands" saying things like "plus or minus 5".
Now when he says "5 tenth", he is referring to 5 tenth of a thousands of an inch, or 5 ten thousands (.0005 or .013mm).
It is actually 5 tenth of the base unit because the base unit when discussing tolerances are thousand of an inch.
Metric is confusing too buddy. People are used to what they use daily. As somebody that as grown up in the metric system (in Canada) and switch to the imperial system in professional life, I much prefer the imperial system, at least in the engineering realm.
"Metric is confusing too buddy."
Mind giving an example?
