- In this episode, Mark tackles a confusing and often misunderstood topic - pull-back/dead-length collet chucks, and lathe part stops. In typical Mark fashion, not only does he give you tips on collets and other workholding, and discuss which part stops are best for your application, but he also explains how the drawtube and hydraulic actuator on your lathe work. Knowing how your machine works will help you make better decisions on your workholding, and there are some great animations in this video to really explain things.

I liked the This Old Tony inspiration at 3:56!
Yay! Lathe videos... glad to see you listen to your customers!
Really appreciate Haas & Co putting these out. Wonderful info.
I enjoy these videos. Tangobaldy is merely a UA-cam addict. Learning stuff I'm never going to need.
Yes the royal quick stop are awesome, the true length comes in handy for second operations and they have integrated stops as well. We used to use a turned down cheap muffler expander inside the drawtube that is similar to the spindle stop from ROVI. : ) Also 5C "emergency" collets can be bored to size with an integrated stop for high-volume production second end operations. : )
I have learned so much from these videos. Thanks for helping feed my kids.
Great mark. It’s really a hard work to make the animations and make it for others. God bless you.
REALLY useful video. These videos add so much to the value of your machines.
And to society in general!
Great to have you back Mark! Thought you had changed jobs!
Seventy 7 Industries - Thanks. The videos are a lot of fun to make. We have quite a few more videos that are being edited now, some really useful topics. Check back soon. - Mark, Haas Tip-of-the-day
Long time no see mark! Nice to see you again.
wonderful information great video graphics and parts display...makes everything easy to understand. thank you.
Great video. Very informative
Wonderful! This might be the reason I find coolant in my hydraulic tank!
Very interesting video Mark, thanks.
Mark! Long time no see. Hope to see more of your videos more often!!
easy for beginner to knowing better of collet chuck.Great video
I use a old TL 1 haas lathe at work with collect stops all day! With a lever I manually pull back my finish part lengths are pretty consistent but they have differed every so often
Great video!
Incredibly informative..
Thanks for all the informations
Thanks - great video!
Great video for Entrepreneurs .
Just in time video, Mark! Thanks!
Thanks Damion. Sometimes things just work out. If you have a topic that you’d like to see covered (or a great tip/trick you’d like to share with us!) send it through to TOD@haascnc.com. Thanks for the comment. - Mark, Haas Tip-of-the-day
Grate video sir I'm very thankful for your work
Thank you for this!!
On my old CTX 310 i tried to use tool as a stop for push colet chuck, the force is so huge - its moves turret in Z -axis with open door and when i close door, turret squeeze thin stock in an arc!
4:16 That statement has a lot more meaning to it after having watched the Pierson Q&A with you Mark 😂
Good explanation of pullback ratio... nice 👍👍 sir
It's just awesome
Thanks for the very useful information and the great video!!!
I would like to ask how to determine the clamping force of the collet chucks? In turning, a collet chuck holds a workpiece with a suitable clamping force so that the workpiece neither moves nor is deformed during machining. Is it calculated by analytical modeling, or is it determined by simulation or experiment? Thanks in advance!😀
Thanks for posting this Mark. I set parts with a home made depth gauge that I use the back of the chuck. Since I c ut the same part most of the time it's a quick and accurate way to set my parts.
StrikeForce Dad - That’s great. Most of the time it isn’t about making the part, it is about making the fixture! - Mark, Haas Tip-of-the-day
You missed a pretty good pun there when you said pull style collets have some drawbacks :P
hlaps1990 - Yes! My notes actually said “..but they do have some drawbacks (audience groan)”. It’s the little things in life. Thanks for the comment. - Mark, Haas Tip-of-the-day
Good video 👌
On manual tool setup - how do the Lathe guys do the Z axis to make it to update off a common surface?
We use a bar pull and sometimes a collet stop that screws into the back. The .006" draw back isn't a big deal because we typically face .01-.02" off anyways. I know it adds up if you do thousands of parts, but it's not a big deal for us
At my work we use one of those style stops you said not to use. We live on the edge all the time there and it would be better to have the machines I run go fubar to get new ones.
Greetings guys. Congrats on making a great machine. This is somewhat of an off topic comment, but this particular video is the reason. I am aware you have recently blocked a super troll pretending to be an authority on all things engineering, machine, and collet, related. Good for you guys. I know this because he has a discussion string on his channel, where he blasts anyone that won't give him a lollipop for his technical input. Me included. As a matter of fact, most of his banter is about my material, so get ready for a spotlight of your own. Its nice to know someone is watching. I won't say the name of the channel, because that is exactly the reason maggots like him, do what they do. Its like feeding on a dead carcass. I too have blocked this clown and urge anyone else getting invaluable advice from Eh&t ( abbreviation ) to do the same. Feel free to contact me via my website contact page if you would like an off air link to the discussion postings. Thanks for your time and keep up the good work on the videos.
On an st-15 could the hydraulic chuck be replaced with a scroll chuck? Would the draw tube have to be removed?
Sir how much force required to clamp the shaft thru collet chuck setup
Hi Mark, can you please do a video on steady rest fundamentals, for both small machines like the TL with manual tests and large ones like the ST50 - a video like the ones Haas has on SSV and using a tailstock would.be amazing as there is little good infomration on using a steady rest! Keep up the great videos
Kristian Thompson Silva - That is a great topic. We’ll put it on the list. Steady rests are really popular on our lathes, from TL’s to our larger ST40-ST55 lathes diy.haascnc.com/presentations/overview-steady-rest-provision - Mark, Haas Tip-of-the-day
@@haasautomation Has this video been made? I would like to watch it but didn't find it.
Why is the machine cannot measure length of the part after it was secured in the collet and apply measured offset to the part's design before it will process the part?
grat video.. even thoug you dont own a haas lathe.. plenty of good tips here ... cheers
Sir,
Price of above Collet Chuck fixtures ??
Hi Mark! Do you think it's possible to make a tutorial on how to use the "pocket program" inside the controller? I have searched all over google and have yet to find something helpful!! Thank you in advance!!!
Hi Mark! I made a mistake, the tutorial i'll like to see is on "pocket milling". Thank you!!
Brian Erazo - Great topic, we’ll put it on the list. Thanks for the comment! - Mark, Haas Tip-of-the-day
thanks
From iraq well done this was helpfull
In Germany we made parts with pull to close collet that have Z tolerance of 0.01, plus minus 0.005. In millimeters.. :D Worked out well, made 2-300 parts a day without an issue.
We have two new Haas st10 lathes with barfeeders and want to use bar feeder for stop but our nextgen controls do not recognize the v axis command.
We are having the same problem! I think a video with the capabilities of the new bar feeder would be great!
In a recent software update, 100.19.000.1100 (BZ628), we added a G266 function that allows us to use our Bar Feeder as a stop, and still have the control keep track of all of our bar feed information for us. Give your local Haas Dealer a call, and ask about upgrading. Thanks for the comment! - Mark, Haas Tip-of-the-day
Great machines. From HAAS. dreams machines
Another good way is to use a tool as a front stop. Like a dowel in a boring bar holder. Then you put a position and an M1 in the program to pull the material out to it.
he displayed that method
Trainedtiger - That’s a great method. Like rick371 mentions, we have something similar at 08:30 in this video. On the mill, I’d use a dowel pin in a holder in the spindle, commanding it to an XY location and then locating my part of that pin as a movable stop, when I had to cut around that entire perimeter (normal stop would be in the way). We have to be really careful with our code though. Thanks for the comment. - Mark, Haas Tip-of-the-day
Please give us back Tool Tip of The Day as a separate channel!
Super video !
COULD USE THE TAILSTOCK AS A DEAD STOP
You’re not supposed to be using material in ”c” type collets, that isn’t of a pretty exact diameter. There shouldn’t be variance. All single angle collets are meant for just one size, the size on that particular collet. Double Angle collets, the ones that are parted from the rear as well as the front, can be used with variable diameters. So those single angle collets should never be used for variant diameters. The problem isn’t so much where the end of the work is, it’s that clamping down on work that’s not the collet size results in the collet wedging and the jaws losing parallelism, and the work wobbles. That’s a far more serious problem.
Daniel Machado - Brazil...
Вот американцы молодцы,просто слов нет.у итальянцев цанги по другому крепятся.
We offer collet for hass
Лайк ,не глядя.ахуенно!
If just the machines where as good as the videos...
The ‘“uhh”’s do not sound natural. You do not need them. Don’t use them.
Bill Kellogg - Uhhh, this is nothing! I had one video where I kept saying “Right” for some reason and had to leave myself a note to stop. Note to self: Uhh, Stop. Thanks for the comment ;). - Mark, Haas Tip-of-the-day
Haas Automation, Inc. Mark, I realize how abrupt I came across. I am sorry. I love your videos, and all can tell that you are an expert. Your reply was gracious and appreciated.
I think it was a this old tony reference
Fantastic content as always…. Happy to have a gently used, like new, MiniLathe added to my shop recently and have been making good use of HAAS online content as I have no hands on CNC lathe experience. ESPECIALLY appreciate the last bit about not attaching dead length stops to back of actuator, the warning sticker is clear, but your explanation helped my understanding a lot (that it’s ok to use a stop threaded into the collet body 😂)
pull to close is the biggest nonsense ever used on cnc machines
