ER Collet Essentials. Do You Know? - Haas Automation Tip of the Day

Whether you’re a beginning or advanced machinist, you’ve probably wondered more than once if you’re using the correct collet. With so many to choose from - and often confusing sizes on the collets - it’s hard to know if you’re using the right one. In this valuable Tip of the Day, Mark looks at each type of collet, and explains how and when to use each one.

Wow, learned more in 20 minutes here than in hours in the classroom. Great job guys!

[@desert_jin6281]

Kent VanderVelden You said it. Very interesting and useful video.

[@mikesinyourtv]

Very well said!!! I agree!

[@christopherclark8454]

Kent VanderVelden idk my teacher breaks it down well I need a physical teacher hands on he breaks the video down

[@toninica]

The best video what i see ever

[@testingbeta7169]

perhaps pay attention in class once

[@A1BASE]

I have no idea how I found my way to this particular corner of the internet but man, this is how educational videos on youtube should be done! Even if I have no use for the information in it that doesn't detract from the face it's fantastically presented and clear as glass. Top job!

[@johnnelson8612]

Mark has done it again! So much GREAT information. Thanks Mark.

[@madmagyver9981]

Thank you. Centering tools with ultimate holding power. Satisfying machinist ocd. This is an amazing service you guys provide with passion. Not everyone gets to hang out with old school machinists. Thanks again

[@Icutmetal]

Ultimate holding power sure won’t come from ER collets.

[@Icutmetal]

@Maciej Jan Długosz Not true; standard shrink fit holders are much stronger than ER collets, but are absolutely not the option with the strongest gripping force. Heavy-wall shrink holders are a big step up, but for “ultimate holding power,” there needs to be a mechanical connection like a “Safe Lock” groove in a shrink holder or a Weldon shank. Even a milling chuck can offer more grip force than standard profile shrink fit holders. Not a darn thing wrong with ER collet chucks; every shop should have some in my opinion, but they’re not the best option for any one thing.

[@madmagyver9981]

@Maciej Jan Długosz collets can achieve more clamping than shrink fit. Shrink fit only allows for a few thousands. Thus limiting actual holding force. Collets use a screw and wedge combination to achieve ultimate clamping force, do the math.

[@madmagyver9981]

@Maciej Jan Długosz actually. If you couple shrink fit tool holders with loctite 680, no amount of physical force will move the tool providing the tool shank doesn't exceed 450 degrees Fahrenheit to release the adhesive.

[@Raptorman0909]

This is precisely the kind of content we love from you guys. Very well done and useful information.

[@georgesalaz8223]

I love this channel. Thanks for all the wonderful, useful information. Merry Christmas.

[@danienathancooper]

Thanks for this. What a great video explaining all the collets. KZbin needs more great videos like this.

[@samterian7694]

i used collets for a looong time but I learned a lot in a few minutes, its like a deaf person hearing music for the first time, thanks a lot.

[@firoxlion]

Fantastic video, great explanation and also some very hands-on shop advise, like rusted collets! Also for me it had a great balance between some jokes to keep it light and interesting, without overdoing it.

[@attilakovacs5803]

Great video, thank you! I absolutely love your thoughtful, no compromise approach, how you consider every small detail.👍❤️

[@muddbutter]

I’ve been machining for 8 years now. Never ran a Haas, but man…I absolutely love your videos. Such high quality, and taught very well. Please keep up the good work!

[@literoadie3502]

GREAT VIDEO! Please do more of these educational videos, good to learn from real experts!

[@TUCOtheratt]

So much to learn... I'll have to watch this several times.

[@MakeItWithCalvin]

REALLY well done, so many little tricks to saving your tooling and making it run more accurately. I can't say how many times I have seen folks at the machining school i went to break all those rules and then some... makes me cringe thinking about it!

[@satibel]

when you don't have the right collet, use a smaller one and a tap with the --hammer-- screwdriver on the end of the tool will do, right?

[@josephelwell2591]

I am going to make this required viewing for each of the operators here at my shop. Great information. You even taught me a thing or two!

[@haasautomation]

Joseph Elwell - Thanks for comment. We loved making this video! It was fun, with all the props. It went longer than we’d have liked, but what can you do, there was a ton of things to talk about. Thanks again. - Mark, Haas Tip-of-the-day

[@GavinBath]

Awesome to see the video! We were lucky enough to meet Mark and see him working on this video when we did the HAAS factory tour recently. Keep up the great work!

[@ScottMoyse]

Gavin Bath exactly what I wanted to say

[@rajkumarukkuturi7115]

Good explanation. Really easy to understand what you are speaking (good and clear English). Many thanks for sharing.

[@user-uv3mc9hi4o]

yes! I'm studying English and Haas's videos helping me with it

[@macstmanj3]

I really appreciate you guys naming the products that you're using

[@SpencerWebb]

Mark, this was an outstandingly informative and well-produced video. Good job!

[@shubhamnishad5926]

Thanks Mark for such an usefull piece of information !!!!! KEEP POSTING SUCH VIDEOS GREAT JOB Guyzz

[@tivnator]

Wow thank you so much. I definitely didn't know anything about ER collets as I thought I knew. Great work!!

[@xavierkaes79]

That was one hell of a clarifying video ! Don't you guys ever get tired doing that kinda stuff.

[@BrilliantDesignOnline]

Mark, thanks for schooling me. Extremely valuable and appreciated with your (and your T2 cyborg unit) classic style.

[@QuebecoisSti]

Thank you so much HAAS for those great infos. I learned alot. Maybe one day I will have my own from you guys :)

[@justinpham4327]

Love those video from Haas, valuable videos for all machinist.

[@JAKOB1977]

damn impressive Haas.. love your videos.. to the point and relevant and in a mannor i can comprihend from a non CNC owner. and it was a huge joy to follow Haas in 2018 in F1.. great team, and Gunther Steiner for prez in Denmark.

[@travisborges1048]

new into cnc you answered every single question i had thank you!

awsome video. im just learning and this the best video ive seen.

[@James-fs4rn]

great info. videos are always well formatted and presentation is great too. thank you!

[@cahman8]

I didn't know about the seal caps. I've got to get some of those! Not as much for the TSC, but to stop the cast iron building up and setting up where it becomes a pain to clean out.

YESSSS!!! More of this! More of the fundamentals PLEASE!

[@Thepriest39]

Great video. I don’t have a HAAS but this video will help out any machinist.

[@oldbloke135]

This is an outstanding video. I'm only a "hobbyist" but I feel a lot more knowledgeable than I did twenty minutes ago and I've already watched four other videos supposedly about this topic! PS. I love the vending machine, brilliant.

I've never seen a CNC irl, but I watched this entire video because it's so well done and interesting.

[@mikewasowski1411]

Incredible info. Loved it. Thanks for sharing

[@Spickygaming]

All i want to know is how you survived getting run over by that forklift at 7:10 ?

[@Thefreakyfreek]

It was his third clone

[@Spickygaming]

@@NeilAbalone Hahahah, good one :)

[@Phantomthecat]

Interesting even that the forklifts and pedestrians share the same path - would never be allowed where I work.

[@jfan4reva]

He called for it to take him back to the machine room. Used the forkLyft app on his phone.

[@haasautomation]

Thanks Jeff. I sent your comment on to the Editor who produced this video, Tyler. He said that next time there would be 4 Marks, and would say nothing further. Thanks for the comment! - Mark, Haas Tip-of-the-day

[@crossthreadaeroindustries8554]

[@adwanlaya421]

Very interesting and learn lots of skills thank you so much sir..

[@k.j.renterprises5816]

Your videos helped so much in my life experience sir

[@Xynudu]

Good comprehensive video. The only thing he maybe should have mentioned was regarding the collet nut thread fit. This has to be close fitting for good accuracy. Worn or loose thread fit is a no no.

[@cahman8]

We have 2 kinds of TSC ER collets, the ones with the rubber seals as showed here and some without rubber seals where the slots are shorter. I've found that the ones with rubber seals have to be on size or the tool is likely to slip. Also the rubber seals will eventually blow out.

[@clifffoltz651]

Excellent information, thanks !

[@BlueCollarDiz]

Great Job Mark and Haas on this video! I’d like to point out one thing you didn’t touch on, that I’ve found employees do in the past, especially when using these collets for holding endmills. Although you mentioned it is important to have clean surfaces on the holder and collets, you did not touch on the importance of breaking down the collet setup when switching out tools in the holders when tools become dull or time to replace. Chips, coolant residue, and debris gather in the collet slots during machining operations. And in changing out a tool when you loosen the collet, this residue can work its way from the slots to in between the collet and holder surfaces. Now when you clamp down on the new tool, you are smashing all of that residue BETWEEN those two surfaces, along with the suraces of the collet and cap itself where those two surfaces come in contact. I know it may seem simple common sense to always break down the collet from the cap and remove it from the holder, and clean all surfaces when changing out a tool. However you’d be surprised how often this happens if employees are not instructed in the importance of doing so.Thanks so much for these videos. They are a great teaching tool. Donnie

[@haasautomation]

Donnie - Great point. Thanks for commenting. - Mark, Haas Tip-of-the-day

[@FredFlintstone21]

We use chip chasers to clean out the veins of collets. Works well. The chaser is spring steel, about the thickness of metal banding, maybe a tad thinner.

[@neilwoodward7336]

Use the 6" steel rule in your overalls pocket. I always have 0-1 mic, needle file & marker pen in breast pocket. Then use airline and corner of overalls to clean. 👍

[@ianjackson8643]

great video , with some great humorous touches

[@htral]

Man - this helped so much - tank you!

[@dalenaegeli3484]

Great video with a lot of useful information. What left me empty though was there really wasn't an explanation to WHY you don't put a larger tool in a collet than what it is made for other than you will damage it. Some people need a graphic or something to see why to really understand it and/or believe it. Thanks for all the great work you do.

[@steinbierz]

Fantastic video and instructor!!!

EXCELLENT VIDEO

[@quotidien_]

Awesome info!

[@salavatfarrakhov73]

Regarding choosing right collet size (at 7:15). I had the following experience: I had big tool runout when used 1/8 inch tool shaft with 1/8 inch collet (ER-11). When replaced the collet to 3.5mm the tool runout has disappeared. Therefore I would choose collet of some bigger size than tool shaft.

[@nojhampton]

Sounds like a damaged or dodgy from new 1/8" collet to me. It would be worth checking the TIR with a measuring pin and discarding it if it's no good. 1 Don't bother buying cheap no brand collets , they're.... cheap! I found 'F' brand are good think it's fahron he showed 1 in the video 2 the 0.5mm collets are very useful for small/precision work.

[@AhiretEkini]

Thank you so much.

[@jlippencott1]

You missed one type of ER-32 in your list. They also make ones with an integral button for the flat on Weldon shanks.
