Lathe Part Stop Essentials. Do You Know? – Haas Automation Tip of the Day

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!

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. : )

Yay! Lathe videos... glad to see you listen to your customers!

I enjoy these videos. Tangobaldy is merely a YouTube addict. Learning stuff I'm never going to need.

REALLY useful video. These videos add so much to the value of your machines.

I have learned so much from these videos. Thanks for helping feed my kids.

Great to have you back Mark! Thought you had changed jobs!

[segwaydave]

Really appreciate Haas & Co putting these out. Wonderful info.

[deepakvaishnav]

Great mark. It’s really a hard work to make the animations and make it for others. God bless you.

[ChillGuy]

Wonderful! This might be the reason I find coolant in my hydraulic tank!

[levenseleven]

easy for beginner to knowing better of collet chuck.Great video

[davidsibrian]

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

[mryoutuser]

Long time no see mark! Nice to see you again.

[Austinfamily]

Mark! Long time no see. Hope to see more of your videos more often!!

[TabletopMachineShop]

You missed a pretty good pun there when you said pull style collets have some drawbacks :P

[shiro-rm]

4:16 That statement has a lot more meaning to it after having watched the Pierson Q&A with you Mark 😂

[HongyuMa-jxjs]

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!😀

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.

wonderful information great video graphics and parts display...makes everything easy to understand. thank you.

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.
