All government and aircraft parts have to be USA made (mostly). Small machine shop I would normally turn this on a screw machine if more than xxxxxk was ordered. You run out of rpm, so cutting oil and steel cutters work great.
Lol you should see the inserts we are putting into a few panels we are making for them. Probably the most elaborate pieces of metal you've ever seen. They are 2 pieces that thread into eachother and we have to put a small dab of Castrol grease on each thread. That grease is $900. Then we pump Hysol glue into the panel around them to hold them in. The biggest panel out of all of them has probably 30 or 40 of these inserts. It's a pretty cool job though.
I am betting that it is about 20 seconds per part. I side for face off side and 1 side for cut off side, less than the main..... I'm guessing some OT. 10 hour shifts.... 5.5 shifts.
I still want to see how they make some watch screws. I've worked with 000-120 tpi, and that's a big one in the watchmaking world. Some of them are as big as a piece of dust but have all the same features.
Perfect setup for a short run where setup time is more important than parts per hour. Lots of opportunity to run this faster for longer runs including rolling the thread from an end slide and replaceable insert form tools.
I prototype a ton of parts when design phase is in heat. I'll tell you what, there are machine shops that own machines like this one and turn up crap parts. There are also machine shops that do not have this sort of sophisticated machines and turn up excellent parts. Otherwise, it is beautiful to watch.
Mass produced screws are made using a cold forming process (i.e. take a wire blank and press them into the final shape via multiple passes). You'd only machine a screw directly for very specific custom applications where the number of units does not make it economical to create custom tooling to mass produce the screw.
@@JamesNintendoTurd actually, i called the screw makers and they explained that every single screw is now made by going back in time and stealing it from an Ikea furniture box. This explains a lot.
@RearwardCasew1 overkill? Probably. A 12mm machine would be perfect for these things though. Ran thousands of screws on citizen A20s and L20s for medical. had some so well dialed in we would change tools maybe twice a week.
Yes, they are. My boss had me make cap screws (100 of them) on a Swiss lathe. They were pricey but not as costly as this. I think a less expensive Escomatic would be the right machine.
Probably around 40 seconds maybe a minute. But times could be drastically reduced. Could also change it to a two spindle two turret machine and work both sides at the same time. Could crank these out in about 20 seconds on a wt-150 style nakamura
@@luke2026 Well, I see it as covering projects that require either really specific tolerances, or parts that aren't conventionally available (say, a weird thread pitch for the size).
This must be a prototype, one off, or a very specialized screw because the old 8 spindle Davenports we run can pop out a screw like that every 5 seconds, thats why we dont take orders smaller than 100,000 pieces.
Ok legit question... formed threads are mechanically superior and can be finished with cutting. It would be total overkill for small machine screws... but is there a tool for it? Can it be done? Because I have used a sheet metal fabrication machine which had M5 inside thread forming tool.
This is very impressive machining but caption is very miss leading tho. Screws and nails are often rolled not machining for industrial manufacturing incase people outside of the field questioning
Quite the contrary! Flat heads really work best for these sizes. The smallest commonly used metric size hex is 0.7 mm. And especially in stainless screws it is very easy to round the drive. With flat head you can put several times the torque on them! I said the same thing when first started working with UHV components. Same for watches aswell.
@@irishwristwatch2487 no it’s not, yeah I detest the use of Philips screws with impact drivers because of that but on such a small screw you could easily over torque them if you wanted, I could break the screw before it strips out but you would have to be trying to do that because it would be really tight
@@Industry-insiderThat’s a good point. Especially those annoying apple specific ones. ;) I really enjoy working on phones because the screws are magnetic and it’s super easy to just pop them on the tool and get them right to where they need to be. The torx and Pentalobe screws do work rather well. But especially hex is really bad in those sizes or at least not suitable for higher torque requirements.
Yeah, you use a smaller and cheaper Swiss lol. This machine is like 4x the size you would need for this part. To the point where it's kinda impressive tbh
@@EPICRANDOMGUY02Swiss machines are screw machines. The originals being Swiss machines designed for making watch screws. Never heard them called sliding head machines.
@EPICRANDOMGUY02 it's still called a Swiss. Swiss specifically refers to a moving main spindle pushing material through a guide bushing that supports the stock.
I dont think I've ever heard the term skim cut,for a finishing cut. Or cut driving slit...i dont know who does the subtitles,but i kinda expected - made in china. Nice job on the machining though 👏🏻
