Machine Shaft From 2000 Lb Stock

[@kennyp9339]

Retired machinist of 42 years in the family "job shop". Toughest part that I ever machined was .507 dia .303 long copper with 14 holes tapped 2-56 X .098 bottom. I set up a tool holder with bees wax that our resident old timer had me try. Went from zero tapped holes to completing the entire job with zero broken taps. 2600 piece order. Always listen to the old timers, he retired at 89 years old and still came in a few days a week just to answer questions right up until the day he died at 94. I really miss him.

[@vitalijslebedevs1629]

Mad lads over 70yo are the best, even if they've learned everything in analog and manual. Passion to keep working after pension age coupled with all that experience is simply unbeatable. Also, copper or Al is not a metal, as hardcore port-equipement millers say. In 3 years of milling haven't had them once (allthough everything with iron in it, plexiglass, nylotron, capron or PVC came up occasionally). I'd rather do Hardox500, than something soft, gummy and unpredictable, due to lack of experience, the main thing.

[@elischultes6587]

Grandad became a machinist after Korea and retired in maybe 94-95. At times I wonder where his apprentices ended up. At the end he was happy just turning out screws all day. I’m not sure I could do the same part for years. He had some interesting projects over time. He helped estimate for a subcontract for M16 receivers. The prints were labeled top secret. He knew they wouldn’t be able to make money getting the contract. He knew that they probably hadn’t had a background check through enough to officially get the contract either. Grandmom was a pacifist and converted grandad after his service. As a pacifist he avoided military contracts unless they were life saving. The quick disconnect for the F16 or 18 oxygen supply to the ejection seat was ok. Polishing recreational rifle scope glass was ok too.

I suggest you write a book about everything you know and have it printed, and as to that old timer, I wish I was there so that with a tape recorder and with 2 stenographers they can record and write down everything he knows with my engineering staff asking him about his knowledge and and asking him questions about his work history, the problems he dealt with and how he solve them, etc. And add that to your book. Computers are good but A PRINTED BOOK MADE FROM ARCHIVAL INK ON ARCHIVAL PAPER WILL LAST FOR MANY GENERATIONS and to pass it top future generations.

His considerations on stress-induced runout made me realise there are so many things i don't know. Sometimes you watch these gents, think it is easy because they make it look easy and suddenly you understand that there is so much experience you need in order to get the job done it is almost frightening. Still glad i subscribed.

[@joachimsingh2929]

The stress is usually relaxed in the annealing after tempering. If there is still warping after that you have to either do it again or take a deeper dive and ser if there could be some inconsitency in the material itself like uneven proportions of The alloying metals causing faulty grainstructure or difference in grain in different areas. Its usually scrap by then. If its mechanichal stress then you either straighten your part or just machine it out .

[@xenonram]

@@joachimsingh2929 there's ALWAYS stresses in stock, especially when you remove 90% of it. There is nothing you can do to get around that. There Monday be a little, may be a lot, and you can do pre processes to minimize it, but you can't eliminate it. The center is holding it and preventing it from springing, which makes it more noticable.

[@darthvader5300]

As a mechanical engineer I will say that, WE OWE EVERYTHING TO THESE MACHINISTS for they can turn any metal ingot into a very useful component for all of the machines that we are taking for granted. Even the UV Lithographic Steppers used in making computer IC chips is composed of THOUSANDS OF MECHANICAL COMPONENTS especially the micro-mechanical components that aligns the protective etching masks, they make the machines used in making the optical components of the lasers and UV beam projectors. The list of mechanical parts is ENDLESS. Your faucets and valves n your households, the car manufacturing facilities, the mechanical components of hospital equipments, the surgical tools and devices. I am you telling the list is super endless! And only machine tools can be used to manufacture themselves starting with the lathe to make the planer, and then the planer is used to make a more precise lathe which in turn makes a more precise planer and so forth and so on. Then they can scale up in size and then diversify into other basic machine tools such as the drill press, the miller, and the shaper. And includes their ancilliary extensions and measuring instruments and devices.

[@darthvader5300]

When I was assigned in Japan under a diplomatic mission cover way back in the 1980s, I saw several basic Japanese machine tools for the Japanese has never and will never forget from learning FIRST all the basic machine tools but this time they upgraded it in using omni-directional laser scanners that can practically scan any item and turn out exact copies of the same components. But they have maintained the same 1950s and late 1940s machine tool alloys used in making machine tools because they LAST AD INFINITUM! I ask them why use the old alloys and they said it is based on their experiences from WW II which they have carefully recorded and microfilmed archived. It is because of the lack of raw materials that they could not make REPLACEMENT PARTS for their machine tools for the war effort, especially the cutting tool bits and tool bit holders. This time they have to make sure that even in peace time, any interruptions from raw materials supplies will not disrupt their machine tool operations and this time for DEFENSIVE AND COUNTEROFFENSIVE PURPOSES to protect Japan. That was way back in the early 1980s and I have no doubt they are still maintaining that policy of BUILDING TO LAST INDEFINITELY.

A Russian engineer told me they already took samples from non-critical locations from the ship and has spent tons of money in scientific R&D trying to figure out on how it was made, and they already knew how to duplicate the process and the steel material. They already built a factory, 8 in fact, to manufacture that kind of steel for the Russian military and it is not available yet for civilian use. But imagine the shockwaves and howl from American iron and steel makers when we Russians will make it available for civilian use world wide! They will lobby congress to stop it's importation but American buyers who are already fed up with planned obsolescence will demand it to be sold to them for all they have to do is look at the appliances made in the late 1940s, throughout the 1950s up to the early 1960s of te grandparents and great-grandparents that are still in pristine conditions and still running strong!

Could save yourself a lot of pain in op2 by using a small bung/faceplate against the end of the part with the tailstock applied, skim a steady band. Apply your steady. Re-face the part and do your end hole so it’s true to the band you’ve just essentially free-turned without any pressure on the centre hole. Now you can engage your centre and turn it all true to the hole you’ve just made.

When i went downstairs he opened the tooling room and said" -please find the tool to make this stupidity of your possible!". 2 years later we were best friends and he taught me how to work (basic stuff) on the milling machine and the lathe. And arranged that i go and do couple of shifts. Afterwards noone complained again from my part designs and i grew huge respect to the wizzards from the shop. I called and asked when i had some strange idea instead of trying to force it on them. This is something you learn your whole life.

Nice explanations throughout for those of us who are mechanically inclined and curious but have little or no 'hands on' machining experience (although having done software development in a group that did fancy, for the day, CAD/CAM over 40 years ago I have _some_ out-of-date exposure). One thing I find myself thinking when watching this and similar videos is how much time is spent on centering (although, obviously on this job with the amount of material being removed it's a quite small part of this total job). It seems that much of this could be done more quickly by "computer + sensors + hardware" under the guidance of the machinist (including specifying such things as max/min jaw pressures etc. as the machinist has a sense of the "grippiness" of various finishes/jaws as in this case). The spindle/chuck could have timing features (maybe at this class they already do) and a "digital" dial indicator being read by the computer. With that, the computer can do the trig to take an initial guess at which jaws to tighten or loosen and by how much and then actually extend a tool to do that to each jaw. Rinse and repeat until spec is met (or computer throws up its hands and cries out for a human machinist). Each iteration would take into account the change over the last try to temper the amount of torque to apply to each jaw adjustment. For extra credit, add a variable strength pneumatic "bumper/vibrator" to replace the hammer and couple that with three digital dial gauges around the circumference at the tail end - the computer could apply force in increasing/decreasing levels (up to constraints specified by the machinist) to the "bumper/vibrator" and turning the piece while monitoring the effect so relatively little "oops, went too far". I suppose version 12.9 of such a system would actually take into account the mass of the piece being centered (assuming a full CAD/CAM system, not just an assist to "old school" machining) to work more quickly and have a wide array of scenarios it could adjust to - but that's probably a bit beyond what would be needed for an MVP. Since this is so "obvious", I assume this already exists (although I've never seen it) or it's a ridiculous idea that has been tried many times and failed for economic or technical reasons :(

I have a stop I put in the chuck. It has a landing that spigots in the chuck bore. It has notches cut in it so the jaws can still close past the bore of the chuck. I have a thread 3/4" unf tapped into it. The bolt has a large ball piece welded to its head and I have adapted a G clamp foot to it. I can them pressure hold a workpiece between centers just like how you pushed your workpiece in at the beginning of the video. By holding the workpiece away from the back face of the jaws, you are not fighting the squareness of the stock. When you get close to size and want to release jaws to minimize stresses and let it relax or normalize it doesn't change longitual position. I didn't know that about centre drills. Helpful tip!

[@davidlampe4153]

I’ve had to get similar work on long parts trued up in a lathe an old timer taught me to use brass shim’s about 1/8 thick on each jaw that allows them to be tight enough to keep the part from falling out but allowing movement when you adjust the runout at the far end to true the part at each end. This way you can cut two steady rest spots that are 100 percent true and allows for easy adjustment. You can switch back to your 4jaw chuck solid jaws without skipping a beat.

Don’t be fooled. I have been and seen tools designed and build in Taiwan. Their skills are also outstanding. The USA has craftsmen but that is changing with few apprentice programs and education geared towards the trades.

It's a shame the chip conveyor broke, hope you can get it fixed soon.

I have literally zero hands-on experience with the subjects, but metalworking (and woodworking) are such amazing fields. You think "wow, it's absolutely insane that they can make a machine that can make something like that!"

[@somethingelse4424]

Run a lot of parts. Take pride in the finished product, eventually you get actual pleasure from holding machined parts, or watching a machine effortlessly throw chips, and being able to make it do exactly what you want it to. I think about it while I'm falling sleep sometimes... A turn tool making perfect discrete chips like fusili pasta and leaving a mirror finish. I've learned the most by having to program a part from scratch with no instruction, make jaws/fixtures, decide what tools, and figure out feed and speeds myself. I learned fastest and the most personally by having to think through all the steps to make a part myself, rather than being handed instructions, fixtures, and tooling. Being able to read GCode as if it were a second language is incredibly useful career wise... It is fairly standard across machines and industries, and makes the difference between being a button pusher or opening doors into engineering.

[@nealrcn]

That is by far the largest lathe I have ever seen. I'm suitable impressed 😁

[@daniloxyz]

It feels like someone should start to forge round stock with flanges: easier to cut off 3x excess length, than to turn down 3x excess diameter... They may even become a standard if there isn't one already.

[@tallswede80]

no the proper way is to use trepanning.

[@ramanshah7627]

I had the same idea - I think there's a solid business idea here for someone with a forge. The hard part is to work out an optimal inventory: there are too many variables in the shape of the blank (2 diameters and 2 lengths) to brute force the inventory the way you can brute force an inventory of cylindrical stock (1 diameter and 1 length). I think one could crack it with the right combination of engineering and relationships with job shops (to gather market intelligence). And if one could, I think there would be some healthy margins there!

It’s wonderful to watch you Chris I’m retired now couple years rent a HAAS TL-3 it had taper compensation I enjoyed your expertise to make your steady rest run part true. It comforted me to see you take prefinished cuts as I had difficulty holding size and taper otherwise

[@jeeprenegade1985]

When I used to run the lathe, I would try to chuck on as little as possible to finish turn a shaft. That way the tailstock center could more easily align the center to the center hole and not spring the shaft. I wouldn't want the shaft up against the chuck jaw face because the tailstock can't align the center with the center hole then. I have usually always saw at least some small degree of misalignment and springing when turning between a chuck and tailstock center or chuck and steady rest. Turning between centers is the best for concentricity and for not springing shafts. Thanks for the concern for detail. It actually took me five years or more to figure out these details you are explaining here. When turning between centers, I would turn a 60 degree soft center on a piece of bar stock held in the chuck and then drive the drive dog up against te chuck jaw. No need to remove the chuck then, and the soft center would run as good as the spindle then.

[@unclelar53]

Well done, nice work. I probably would not have thought of that strap trick for finished part removal. Sweet.

[@campbellmorrison8540]

That is one very scary lathe. Just imagine what would happen if you muck up the command and move the decimal point to the wrong place. Definitely a pro required here. Fascinating to see the pressure of a hand bending that rod!
