Who is milling bolts that hold airplanes together? No one. They are formed fasteners (warm formed or cold formed) through a heading die. The first bolts shown were grade 8, then he showed milling brass.
I remember they switched a lathe from tubing to solid metal. The clear aluminum alloy door window is no longer clear. Nothing but spider web cracks. The person switched the program but didn't switch the chuck back to hydrolic from air. The operator received shrapnel, which was not visible on the X-rays.
The Power tongs we use on rigs have these I always check em so I don’t die 😂bolt missing ain’t to bad tho as long as it didn’t fall downhole just don’t die
How about scrapping the workpiece, how about damage to the machine, how about possibly wrecking your spindle which may then cost 30k or more to replace and weeks of downtime
Starting my second year of trade school “advanced fabrication“ machining and welding essentially now we have really nice manual mills with good DRO’s I think there the haas touch screen ones could I program something similar most I’ve been able to teach myself is like plunge cuts and stuff
Hmmm your running’s 5000 rpm to accommodate for the slow feed I do like how you did that. Now those small chips look great, also I would like for you to do it running some 304 stainless steel.
I gotta ask, why make the demonstration show the least strengthened position of that safety wire hole? Don’t be mistaken, its still strong, but depending on the kind of wire vs stress reactions, the small bit of material left over could shear. Typically you see it through the center to prevent that. However, I could be wrong as depending on where it is its located, it could be a precaution against trappage or a planned failure in order to ensure proper maintenance management. Could also be a training bolt.
