Aluminum Standoffs Machined in the CNC Lathe

[@proberts34]

Hey Adam. I like the mix of old school manual work along with the CNC work you do on the channel. You have an extremely strong foundation of knowledge, and you can leverage that to do some of your small-batch work on the CNC machines. Keep up the great work. 👍 Over the years that you've been doing manual machining, you've built up a wealth of skills, expertise, and knowledge, and it's great to see you apply those skills in your videos. At the same time, CNC work is the future of a lot of shop machining, particularly when it comes to small batch jobs like these aluminum standoffs. It's great to watch you develop those CNC skills. Thanks for sharing this aspect of your life with us. 🙂

[@Abom79]

Thanks for your comment.

[@judocaADC]

You are a highly gifted machinist. But your greatest assets are your honesty, precision, and ability to communicate a process to a novice. You communicate the intricacies of the process, even when the errors might not be evident to the viewer. That's why I never get tired of watching your videos. Another fascinating thing I truly appreciate is your cleaning of particles from contact surfaces. You articulate extremely well and would be a perfect narrator for documentaries.

[@Abom79]

Thank you for your comment.

[@stuartschaffner9744]

Congratulations on your small CNC project! Your skills on your new equipment are showing maturity as you adapt to what tools you have, without breaking any.

[@satamanschmidt3428]

More likely not breaking any that we've seen.

Seeing a small production run like this makes it easy to understand the power of CNC. Thanks.

Amazing work showing those who are oblivious to how things operate mechanically and explaining to them how something so simple can LITERALLY shutdown an entire airport luggage system. Hopefully they see this and walk away with a better understanding of why they’re being delayed from getting their Starbucks on time because they were stuck finding luggage.

[@hdfanboy]

The collet holders you have for your drills are the best way to hold small drills like that. We use basically the same setup except we use ER32 collets for consistency since our live tool holders are ER32 as well. For our larger drills which have 16mm shanks and above we use custom made sleeves which then mount direct in the tool blocks.

[@AmiPurple]

Thank you Abom for a great video. Appreciate you putting these on KZbin for all of us

Test alcohol for tapping holes in aluminum. Works like charm. Even brakecleaner works well. Stops the taps from galling up from the aluminum. Dont know why it works. But there is a nice bonus of easy cleanup for parts that are to be welded.

[@pekkahelminen7801]

I came across an article that said brake cleaner and welding is a bad combination. It produces phosgene gas, which was used as a nerve gas.

[@chucksmalfus9623]

Funny story Adam, I had a machine shop teacher in the 1960s that would stand behind you while you were running the lathe and when you removed the part if you took your hand off the chuck key without removing it he would slap you in the back of the head. To this day when I see anyone take their hand off a chuck key I get a twinge , funny part is it’s even on a chuck that doesn’t rotate like yours on the tapping table….😂.

Nothing like a customer job to push learning ahead. The most compelling and interesting viewing for me is always real money work or other actual practical needs for the shop or life. I'm a completely manual machine guy but I really enjoy following along you learning a new skill. In any case, CNC is inherently interesting as one of the 'new' fundamental manufacturing techniques of modern civilization.

[@larryrobinson7492]

Setting up a part stop is easy to manually add to your program, just set it like any tool for the X and Z then just program something like G00T0303 G00X.75Z.015M00 Pull the part against it, then G00X10.0Z10.0 G00T0300 M00 not sure how much room you have to move in that little lathe but, it's very handy to get used to doing some manual programming for quick edits or adding stuff like that. That whole part could easily be manually programmed pretty quickly and it's good practice. I understand the fact also of learning the software, I also do that but I like to make sure I stay sharp with quick program edits at the machine for dialing in chamfers for nicely deburred parts, etc. Love the CNC content, Outstanding.

[@dominicwroblewski5832]

My hat is off to you for you journey into CNC machining. Learning any kind of new way of doing things is really challenging no matter what the field you are in.

[@horseshoe_nc]

A thread forming tap (roll tap) would have been perfect for that run of parts. I'm enjoying watching your journey into the CNC world.

[@tomp5377]

I enjoy how such a small part can have such a large impact on many people- even with the weldors and suppliers. Nice production run! Thanks for sharing the story behind it too.

[@mfx1]

Someone needs to be asking why it fails enough to be an issue and why they chose aluminium in the first place.

[@MikeBaxterABC]

27:43 I enjoy the CNC videos, reminds of MY days in the machine shop! :) .. Love the idea of using the parting tool to cut the 45° angle too!

[@MF175mp]

That's used a lot. In fact people without turrets or gang tools make sometimes entire parts with just the parting tool to avoid tool changes.

[@wildironmedia]

We often use a rigid one-piece bushing directly in the tool block and grind a flat spot on the drill and engage that through the tool block with your set screw. Obviously having hundreds of of one piece bushings gets expensive. We have about 50 of them for common drill sizes. The ER calling system the way you're using it is a really practical solution that many people use. What's good about the ER solution is you can use all the same tooling in your milling machines and your manual equipment. Lots of shops just have ER 16s and 32 and they do the majority of their tool holding in those two systems across all their equipment. Love your channel Best wishes

[@bulletproofpepper2]

Thanks for sharing. As a hobbyist your manual machines are four times bigger and powerful. I love to watch anyway the cnc stuff is a bonus.

[@davidgibson6909]

You could also use a VNMG to profile the od with the 45° at the partoff location and save time and your tungaloy.

[@BerndFelsche]

Nice video to show how you're learning CNC. I have a bone to pick with those who designed baggage handling equipment like that! All I can do is hope that they have learned from their mistakes and that nobody else copies that design to create more unnecessary problems.

[@zorzyk6790]

When I worked in the production of lathes, it was no mercy, a giant radial drill, an m6 tap and a blind hole. No clutch. In the beginning, I broke things like that on a regular basis and you had to chisel it out and then plug it and drill and thread it again. I got so good at breaking a tap once in a thousand holes. Practice makes perfect.

[@ericrichards5862]

Thanks for the videos Adam, I'm always learning from them. I've had great luck using form taps especially on aluminum.

[@PerformanceDrivenDesign]

Hi Adam! You're holding your drills in a good manner. The ER Collet holders like you have are the most versatile and effective means of holding drills available. Maritool has a great selection which I've used many times! Unless you need the projection length to be very small, the ER collet is the way to go. It is very sparse that I have been able to push a tool hard enough to spin it inside the collet without the tool failing or pushing the stock back in the chuck. On select instances, many of these ER collet style of holders will have provisions in the back of them to plumb coolant lines into from your tool blocks, which can be very helpful in getting coolant where you need it most for drilling operations. On a few select instances, if I am using an insert drill body or a very long fluted drill, I use strictly a split bushing to eliminate as much hangout as possible. Hope that gives you some piece of mind my friend! Love seeing what you're doing branching out into the CNC world.

[@wireedm1]

It wasn't an issue in this situation, but something to keep in mind on a CNC lathe turret...when you have two or more drills next to each other and you need to drill a deep hole with one of them, there's a chance the adjacent drill in the turret can hit the chuck jaws. You might want to make it a habit of putting drills, center drills, etc., on every other turret station to keep them from hitting the chuck. Always enjoy your vids, keep up the great work.

[@haydendenard2693]

Adam I have gotten busy and haven't had the time in the past couple of years but I got a lot of inspiration from your videos and got my great uncles old Bridgeport and monarch lathe it's cool to see how you've been able to progress into CNC and still do manual stuff I like seeing small businesses growing instead of huge businesses putting people out of business

[@bigalhudson]

Great video and appreciate your dedication to keeping it a mixture of old and new school. I expect maintenance on baggage handling equipment is zero, so money to be made replacing parts until they start maintenance or buying decent equipment. Thanks for your ongoing work posting these great videos. Al U.K.

[@jonasbartels1716]

Great video, you did a great job! We also make aluminium parts at our work, with sometimes really small threads (from 2-10mm in diameter mostly). In my apprenticeship I learned cutting in aluminium with Petroleum (should be kerosene in american English, sorry I only know the german word), because the Petroleum seperates the aluminium shavings from the tap and prevents microwelding of the aluminum onto the Highspeed Steel-taps, also reducing the amount of material left on the tap, while creating a really great finish on the threads. Coolant also works, we simply use the coolant from our CNC milling machine. About the tapping arm moving on its own: You might create a holder with a magnet in the base, with a pin on the top just like the tap holders you insert into the arm. Then you just fixate the arm on the table without the arm swinging anywhere.

[@HybridiHippo]

Hi Adam, i am using ER32 collets and i also hav cnc drill chuck for lathe but it makes drills go so far a away from revolver and makes problems when using outside profile tools. I hav VDI40 tool holder in my revolver and it is easy to swap drill chuck for the one off drilling like manual machine. The Fusion 360 Parting issue that you mention,,, it was only one tab missing from "PASSES PAGE" Allow rapid retact other wise it rectact by feed for revolution. I would also tap batch of those threads in flexarm it is much quicker to do and you can apply lubricant every hole. FORM TAPS ARE YOUR FRIEND!!! Tapping in CNC lathe is very safe i say. Drill deeper that you need for that TAB and BOB IS YOUR UNCLE Tapping cycle is quite slow in my machine any way. Chuck sync take time the tapping is very quick. Your learing curve for cnc is

[@Vankel83]

That's how you hold spot drills, drills, taps, reamers. I use ER16 and ER32 collets. If you have thru coolant available, pump it right thru. Might have to take set crew out of center of holder. The bushings are better suited for boring bars. The set screws align with the flat to put on correct centerline level.

10:51 When i was in the production shop ALL the CNC Lath I used ran 20 foot long feed bar pushers, 90% of the jobs started on full 20 foot long bars. We always feed out on the Parting tool!, ON your new Parting Tool we'd feed out RIGHT where the "Tungaloy" Logo is, on yours!!! :) How I'd do it on this one is after parting, and AFTER the Parting Tool ai back at home position, advance again, to thee length you want to pull out and minus 2 1/2 or 3", Then PAUSE. Then pull out the part against the "Tungaloy" Logo and close jaws ... The return to home position, and PROGRAM END Then check if it's right (It will be very close) , modify the last action before Pause, to correct ... and your DONE!!:)

11:14 After cutting, move the bedame away at z (as far as it touches the material) and x-20, x-30 (see how the material touches the back of the bedame) and then M00 (temporary stop of the program), touch the material, and then in the program move x and z to a safe exchange point and M99 to restart the program. That's what I do at my job

[@jacevedo497]

Hey Adam, i used to make videos of some optical lens turning in a wet environment. What I found helped keep lens clean while filming was building a locline manifold with 3 air blades. One on each side of the GoPro and one blade pointing down at an angle from the top. Use a mag base. Maybe it’ll work for you as well. It doesn’t take a lot of air, just good angles. Noise shouldn’t be too bad. Just a thought.

[@TheDefeatest]

I use ER collets in solid bushings for all kinds of drilling and taping. The odd time they can slip, but for years they have worked well for me in mostly stainless too. Dorian tools makes solid bushings. Also you can probably already have a groove/parting tool that will take all kinds of side load and is really the best of both worlds for grooving and parting off. 1 in tooling can let you part off 1.25 in bar with no hole going thru.

[@MrBrick96]

We use our own made bushings as drillholders. OD matching the ID of the block and a sholder for contact on the Blockface ID for yor drillbit. The drillbit is hold with setscrews. Simple and easy to make and it works.

For setting a pullout stop for your stock, make a sub program you can drop into any program using your rough turning block as the stop and give it a tool offset that your unlikely to commonly use, like T0132. Make it .02 past you G54. As you change your G54 for pullout length, your pullout stop always moves with and leaves .020 to face away. Hope this helps.

[@TomTalley]

Good one. Suggestion. Mount a battery terminal cleaning brush in one of the holes in your table...when your through tapping, stick it down on that brush and figure out which way to turn it to clear the chips..leave it there...brush will hold the tap...easy peasey....😊

[@tumbleddry2887]

Your footage was good...pretty hard to get closeups with everything that's going on...and shields probably don't help all that much (shield gets full of coolant and blurs the view). Great video and project. Thanks

[@SUMOCAT86]

I use similar Er collet holders for solid carbide drills and reduction sleeves with a slot (no split bushings) for the er collet holder. For exchangeable tip drills and indexable drills only reduction sleeves. Through coolant in every tool.

[@felderup]

you could probably build a camera case for wet environs, clear pc tube, rotates with a small motor and belt, little squeegee under the lens, should be easy for you.

[@Illtakeakersakerslight]

If there's room in the turret, use a tension/compression tapping head and a roll tap for the blind hole so you can get it all done in 1 op. in the CNC. Accupro makes a good one for about $250 from MSC. The 1" shank version can fit 4-40 up to 7/16" taps.

[@pedub2222]

Hey Adam, long time fan, I know your just learning cad- cam but a plunge roughing cycle might be good for that tool, I've been machining for 40 years, mostly turning and still love it, my advice to you is learn G code along with the cad cam, it helps to know what the program is really doing. I will be ordering a new t shirt from you soon, the 1st one is wore out, lasted a long time. keep up the good work!

[@pedub2222]

Oh yeah, I use the ER collet all the time they work well, as far as the stock stop that would be a good little G code practice program, I can show you, it's just a few lines of code. let me know if you want me to show you.

[@MechanicalAdvantage]

@@pedub2222 While knowing g-code is handy, the simulation in CAM shows you exactly what the tool will be doing. We considered using a grooving tool, but it still left cusps on the taper. So we decided to give this method a try to see the results and how that parting tool liked a load like this for future reference.

[@fredinit]

Adam, Great work on Fusion 360. I had a small home project using some 2040 channel extrusion. Instructions said to use self-taping sheet metal screws to hold a part on the end. I thought.. how would Abom do this? The right way, only! So, I ordered some M5 spiral taps, the correct drill for them, small jar of Anchor Lube, and the correct machine screws. I'm much happier with the result - especially since I needed to take those joints apart about a dozen times as I fiddled with it. Something the sheet metal screws would never had let me do. Continue to show us N00Bs the difference between GitErDone and a better way to do it.

[@PaulSteMarie]

Collis makes bushings and drill drivers in a large variety of sizes. MSC has them and i believe KBC does as well. Also, I agree with your tool supplier about side loads on parting tools. I'd cut that taper with a VNMG insert and a slight negative feed angle. It is good to know, however, that you can get away with it on s pinch if you're careful. I'm a bit surprised you didn't have a small can of solvent and a toothbrush for those taps. I would be using A9 on aluminum, not Anchorlube, just because it's easier to clean off chips between holes. More personal preference than anything else, though.
