everybody talking bad about the lack of ultimate precision has never worked on old machinery, lots of shims to get tolerances right.....and given that these cranks are for large compressors, even the throw angles can be off several degrees and still work fine
For the price of a pair of safety glasses, is it really worth losing an eye and being left unable to work and provide for your family?.... The management of this company should be ashamed to allow it's employees to work without even basic safety protection.... To put this video on RU-vid for the world to see is just beyond words.
I’m already surprised to see they are wearing sandals instead of being barefoot… and then these sleeping gowns they wear, if it gets caught in the lathe…
I’ve talked to people online who work in shops like this in these countries. They won’t even let you send them free safety glasses. I think there’s a lack of proper safety culture, and honestly I don’t think anybody who isn’t there and in the middle of it can actually change it.
Lol I want to see you walk from your hotel to a Cafe in Pakistan without soiling yourself. You're spoiled. You're right, but the fact you made that comment means you know nothing of the world outside your sterile environment.
Lol, you think they only make one a day? Look at the actual bench faces and cutting heads, they are all in good condition and oiled, even I they are older than both of us put together. I would guess they are on per piece rate, so fluffing around to make yourself feel better is an expensive hobby when you could be knocking out the next part. Dont worry the swarf will be collected for scrap and in the crucible by the time these guys are having breakfast the next morning. @and9290
I am glad that you showed such interest in this video. Thank you. Actually, this man uses their specific measuring instrument for getting the precise position. But that is shown less in three video, may be you got skipped that part.
On a crankshaft, measurements taken without at least a micrometer will soon cause the engine on which it will be installed, many problems... or at least a shorter life.
This is agreed. But here this man manufacture crankshafts for different machines used in factories and mills and they had done it for more than 40 years and they got zero complaints up-till now. So these are experts in what they do and had got a super master skills. Also they do take measurements on different compasses and micrometers. There job would be incomplete without these measuring instruments. May be you have skipped that part of measurement of crankshaft in this video.
Все це робиться без часових індикаторів,мікрометрів,без подачі СОЖ і термічки.Ще й сплав невідомий марки ХЗ.Правда гаряча ковка заготовки присутня.😂 PS:статичне і динамічне балансування теж не проводять.Для парового двигуна згодиться.
Seems like you have got good information regarding making of crankshafts. Here in this video the crankshaft is measured and a sketch was drawn before the process. This expert man use different types of measuring instruments during the manufacturing process of crankshaft. The supplying of coolant inside crankshaft takes another process and that is not covered in this video.
Сталь как раз таки нормальной марки - они режут заготовки из колена от большого судового двигателя. А вот к технологии мехобработки есть вопросы. Но это колено скорее всего пойдёт на какую-нибудь водяную помпу или что-то подобное. Так что сойдёт...
I wonder how many times they have had a crank jump out of the lathe, especially when cutting those big end journals. The weld holding that flange at the tail ought to be , er more substantial !
Ok result apart from lack of PPE, but theres no way that key is on TDC. Should clean up crank cheek faces in slotter prior to alignment of slotting keyway. And hows the drilling of the end of keyway in pedestal drill, wonky & on the piss.
