Essential Machining Skills: Working with a Milling Machine, Part One

[@RenewTheRWandBlue]

Love these old instructional videos. No goofing around, no stupid humor, just straight to the point, quality info. Thank you!

[@kurtfrancis4621]

Thank you for posting this now 23-year old video. For those complaining about the quality, the end of the video shows it was Copyright 1995 by MIT. Thank you for the refresher. I learned the basics of Bridgeports back in the late 80's as a young co-op mechanical engineer, and it is always nice to refresh the memory with the basics of machining technology.

[@shuff1111]

That's really how bad video quality was back then? Seems that i remember video quality in the 80's being better than this!!!

[@petermurphy3354]

@@shuff1111 TV's were much lower quality, didn't show up the low quality of the video. Also this has probably been copied a couple of times ie VHS to CD to digital.

[@taebert]

It’s funny how fast we got spoiled by hi-def video. Otherwise this is awesome content. Many thanks for making this available.

[@alanreynolds5985]

A friend has just purchased a milling machine and has no idea how to begin to use it. Thanks to your video I can now show him the basics. A very good instructional video.

[@danmccurry3810]

This is the best instructional video on the most versatile machine the machine shop has ever known. I will share it with a few would be vertical milling machine operators.

[@kustomhooligans]

Everything he taught in an hour, took me 2 years to learn teaching myself and asking my neighbors who are plastic mold injection makers! Great starter video to cover all the bases of a typical mill!

Outstanding indeed! You need to publish a series of technical videos, and benefit from your expertise as a professor of Bridgeport. I can't tell you how refreshing it was to watch your video, the comprehensive information, detailing the very basics, adequately covering the details and responsibilities of an accomplished machinist. I can't thank you enough!

[@LongIslandEddie]

Your video is like going to Bridgeport college! The presentation is concise, thorough and refreshing to those who have worked the Bridgeport as long as I have. I see myself in you, your knowledge, the presentation of the message, perhaps the comprehensive way that you have made the Bridgeport so worthy of it's importance in our hope to keep the machinists trade alive here in America! Thank you.

[@glenj.taylor2938]

Thank you for sharing this video with us. I'm just starting out and currently in an intro class at a Junior College. I found that what I've learned so far was directly reinforced by the information presented in the video. I'm looking forward to the rest of the series. 🇺🇸 To those who are searching also, I read ALL the comments before posting and here's the breakdown: Video was produced in 1995 By MIT. It's audio is only one channel so may only hear it in the right side. It's a bit blurry but oh well... There are plenty of haters in the comments so disregard them. Just focus on those of us who add to life and not detract from it. Adopt your pets if you can and please spay or neuter them.

[@paulcastro1361]

Thank you so much for your time and effort. It's invaluable for many people who want to get stated on machine work. I don't understand about the people who gives thumbs down. They aren't doing anything in helping anyone increase their knowledge, and make them better machinist like you are doing in such an unselfish way. I know it takes a lot of time to produce and edit a video, something they don't help with their negativism. Thanks again and please keep up with your excellent work!!

[@aquilifergroup]

Paul Castro yeah some people are just dicks. It’s a great video with lots of info and people just want to dump on it.

[@angelomon9382]

Thanks for your efforts.. I am entering the milling work world. I find this detailed work as a tremendous information resource. I am very much indebted to your care and demonstration of machines.

[@jawjuk]

Thank you for some great milling basics, Jesse Ventura! Just what I needed before heading to the shop.

[@inund8]

My right ear is learning soo much!

[@SUM1SLY83]

[@AlwaysWrenchin]

Haha I had to go to a different video to make sure my left one still worked.

[@LILAZEPAM]

Thank you for bringing this up. I noticed only the right speaker on my PC was working. Creeped me out.

[@davidstanford3816]

Very clear and effective explanations. The edge finder operation is the only one that needs expansion. Thank you-I will be watching more!

[@raymondmiddleton308]

Best teacher on KZbin thanks very much and a merry Christmas

[@PrometheanBlade]

The gentleman demonstrating in this video does a great job, I am very grateful for the quality instruction!

[@RickRose]

Nice explanation. Don't have one for myself (yet), but everyone I watch on KZbin has one! Great to see a simple functionality breakdown.

[@YakkoFigueroa]

Excellent videos. Many many thanks Erik Vaaler. You´re the boss man. The quality and clarity of the explanations is great.

[@hintzofcolorconcepts]

I knew all this already, but its great to get such a comprehensive refreshing course before using such dangerous machines again after not using them for so many years...

[@Hooooooyeah]

This was such a helpful series. Wish there were more!

[@Jonb782010]

Amazing videos! - thank you so much for these , I only stumbled across this today by accident but have been searching for something like this for months but I was putting mini mill in my searches 🤔 & my mini mill arrived a few days ago but only unpacked it from crate so far 😂 but after these videos I can now “ SAFELY “ feel confident to operate it & not destroy it , although it’s only a mini 500w still more than enough to cause damage to user or company .

[@paddywalker4537]

I'm new to machining and your videos are a huge help, very clearly explained.thank you so much. Please keep it up.

[@emph66]

An excellent primer very well presented.

[@maxleanr6]

Thank you and keep up the great work. I'm a new hobbyist and this is awesome

[@JanusXAlvarenga]

Great video! Easy to understand and informative. I am a student in the trade so this has helped me much!

[@Jhihmoac]

Nice! This is how I initially started my apprenticeship years ago...You have to know WHY you are doing a process, and manual machining/protowork is the best way to learn...I had to master manual operations (milling and turning) before I ever got on anything with a CNC...

[@ahpplejuc]

This channel is awesome very high degree of technicality & v useful. Thanks!

[@userwl2850]

i have 2 of these machines. they are very reliable and great to work on.

[@kf6pxa]

Excellent introduction for beginners. Thank you!

[@arneminderman3770]

Thank you! Great info! Greatings from the netherlands.

[@mikereed7126]

Excellent vid, really enjoy, will be recommending to some people for a class. to be fair on your shop etiquette part regarding vice square - if they walk up to the mill with a really expensive part and fail to check square on everything before cutting, regardless of how it looks, the ruined part is on them. to anybody contemplating using one of these machines - always check square. always. doesn't matter the time of day or the phase of the moon, any part worth your time can wait for you to properly check everything before cutting. Measure twice, cut once.

[@idomake4429]

Nice video and very good play by play. I am going to respectfully disagree with you on the quill feed application. The quill feed is NOT to be used for drilling. There are very good reasons for this. First is the fact that it does not have the range of feeds per revolution to achieve the proper feed over the range of sizes of drills that may be encountered. Any attempt to drill to fast will result in tool deflection (resulting in an oversize off location hole) or tool breakage. If the drill is fed too slow, it will not achieve purchase on the material to be cut, it will then over heat and become dull. If the drill is big enough the gear train will be damaged. What is the quill feed for? This feature is for use with a boring head. In a boring operation, feed is much less critical and the material to be removed is minimal, less than .005in per side. I spent a dozen years in job shops and the last 15 working on machines just like this. I have seen the results of feed mechanisms being improperly used. Feeding a drill with the boring drive will break things.

[@prenticeemler7709]

Just wanted to say thanks for the tutorial, learned lots , thanks 🤗

[@Les__Mack]

Thanks very much for making this video! I learned a lot. Great work!

[@mastersofharmonica6200]

really great video and lots of detail...perfect for a learning craftsman

[@ArcadiaInferno]

Great video for the basics of a milling machine. I'm sure even some professionals could benefit from some, if not all, of this information.

[@gbouc1536]

very good explanations, easy to follow and understand.

[@mattoslee]

Very nice video, I am running cnc but sometime manuals mills, this video is a good review for what we as a machinist should know and consider, good job.

[@tokenlectronix5223]

Thank you. Invaluable knowledge shared, not to technical and masterfully explained.

[@thecopcarconnection]

Ha, I have been "faking " being a machinist for 10+ years at my co. as a jack of all making little widgets and fixtures and stuff but never knew the quill feed kicked off like that ....I don't use much if at all since most of my stuff is tiny so there is no need but I thought it would just destroy the gears if it deaded into the stop :) ....I use the stop for manually drilling or plunging only if I set the stop. I love this youtube school !!

[@grgc5409]

I didn't know Ron Swanson was making KZbin Videos! In all seriousness thanks for the comprehensive video.

[@MyJigarpatel]

Best video on milling machining. Thanks for sharing.

[@DavidJones-we2ex]

Thanks for taking the time to do that.

[@VIKRAMJAI1]

Excellent video !

[@ypaulbrown]

One error I noted, at the very end, he referred to the Reamer Adapter, when it is actually a Morse taper to R8 adapter. Could also be used to hold Morse Taper Drill Bits or other Morse Taper Tools. This is a very fine intro into the Bridgeport Mill. When Tramming the Head, no mention was made about Tramming in the North/South direction, only the East'West......opps.....Cheers MIT.....otherwise a very well explained video.....Paul

[@nathanowen42]

My left ear enjoyed this very much!

[@WhyCallMeLordLord]

Thanks to this video, I was able to machine all the projects I want to do that were on my right. I'm waiting to hear what the left side thinks still.

[@mrdberg7]

Excellent video! A++. Thank you!

[@fickleman7793]

Great vid!

[@殷佳玲]

Binder cylinder can freely adjust the thickness of the wood feed wheel height,easy operation.

[@dannyoktim9628]

I'm a retired toolmaker that enjoyed your vid, I think the most important takeaway from this vid is shop educate, NEVER amuse the previous worker left the equipment in a "strap it down and go" condition. If you screw up a piece it will be your dumb, and when you explain you will hear "didn't you check the equipment" before you cut? As an apprentice I learned this early, I set up a 1x6x19 inch steal plate on a Bridgeport to mill a .750 slot 5 inches long .250 deep with a 2 flute .750 end mill. Checked my clamps, set the end mill speed, cranked the knee up and set my zero. OK, lets take a .030 cut. . .I cranked the knee up .010 and the end mill garbed and walked across the part and slammed into my hardened clamp. What the F!!! Rule One. . .Never Amuse. A worker had used the mill for some offset turret work and neglecting to tighten the turret bolts when he returned the mill head 90 to the table. People forget things, get rushed to a new project or just have a bad day, yes I was upset and could of been injured but I wasn't, needles to say . . .the part looked like hell! Teaching safety is just as important as technique, an industrial accident may not only involve the apprentice but his master and near by coworkers too. For everybody's safety, never assume! Subject change: I had to move from shop to shop to learn. . . now I watch You Tube! Keep teaching . . .your doing just fine.

[@MichaelDowComposer]

I asume by "amuse" you mean "asume"?

[@racaldana1922]

Terrible English

[@gilbertodiaz-castro626]

Michael Dow I see this a lot caused by the "spell checkers": when they were put together many words were left out so it replaces what it believes to be wrong with the really wrong word...

[@Stepclimb]

Michael Dow I assume by “asume” you mean “assume”?

[@d.4130]

Good teacher,thank you!

[@bobweber4140]

Great video thankyou for your time and effort

[@219garry]

I would not tram the head with my indicator in a drill chuck. I attach it right to the quill with an indicator holder. I also tram it to the table with a stack of identical heigh blocks. If I do tram to the vice I use a longer flat bar for better accuracy. If that head is out .0003 over 4 inches it will be off a bit much if you're working on a block that's two feet long. So I usually tram to the table and then make sure my vice is on dead flat. I've actually seen vices out of parallel by .001 before checking them on a surface plate.

[@brandongarretson9475]

Thank you for the great video! Was it filmed in 1972?

[@dcptp]

Thanks this was very informative.

[@jmbstudio6873]

No audio. That is highly, highly disappointing. Watched all the lathe vids and was excited to see the mill vids. Hopefully the other mill vids have audio. Thx for the super valuable info from the other vids I have watched.

[@haroon3ddesigningacademy]

Nice machining skills

[@josearigojacobojacobo1434]

una excelente enseñanza muchas gracias.,👌😀😀

[@bloodyripperau]

Something you left out on the quill feel was the forward/natural/reverse pin that is located in the centre of the fine feed handle that you are missing from the machine.

[@bloodyripperau]

also when tramming the head you will notice on the front of the quill depth stop there are two machined notches at the top and bottom of the screw they are machined square with the quill so one can use a 12"' square off the table and tram both the tilt and the nod of the head.

[@antonemilit2178]

Great work! Even under the influence of a mustache!

[@freemanfreed1581]

for aligning the vice does the jaw surface deviation will not affect the dial ??

[@geraldestes2470]

the head assembly typically pivots as well as rotating. - so about 2 mins.

[@karlomoharic3992]

very nice and informational video

[@manga12]

hmm ah so so that is why it is called a knee mill, I thought it had to do with the hight, it goes in and out, and the turret turns as its not stationary till you want it to, but this is new to me, I mean I have seen mills and using a mill to flatten out tops and cut groves in plates of metal as well as cleaning parts up, though I have seen that mostly on lathes. but this is fascinating you can speed it up and down just like that by winding it.

[@mk7mk777]

looking at index vertical, great video.

[@davidwoodcock139]

Could I ask why haven’t you go a power drawbar? So much quicker

[@danieltweit3702]

So much information thank you

[@hakimmic]

Very helpful. Thank you.

[@williamskinner2732]

You only show truing the head up 'side to side,' on a Bridgeport it's much more fun truing the head 'back to front,' because the head moves up and down as well.

[@dnagill8712]

would anyone please tell me what that quick clip is called that was used to stop the automatic feed of the quill? I would like to buy one of these and I am not putting the correct words into google- google is not finding it.

[@greg3244]

It seems to me that your stacking errors by tramming your head against a vise. Why not tram the head of your mill using the top of your table? Your vise sits on that anyways, and any error in your table is just compounded by the error in your vise.

[@Randomhats979]

there's no sound for me for some reason

Pound on the draw bar with a HAMMER !!!!!! he should have said TAP it with a hide or plastic MALLET, brass hammer or a chunk of lead. I hate to think what the draw bar end is like, mushroomed out I suspect, making the spanner difficult to fit. Also when aligning the head, there are adjusting screws that work a worm and wheel to move it, there is no need to bang it with a hammer.
