From mechanical and machinery skills looks great, but I hope they didnt expect long term reliability. Someone broke 1,5cm of metal on each side plobably from metal fatigue but after repair it held only by tiny pipe and shallow porous welds. In this case threads doesnt hold any forces, only positioning and centering parts with small play because this threads are not tapered or hard tightened to the other part.
Using a thin grinding wheel, he could have ground a deeper keying slot in the dead tooth ! & when welded in, it would be even far stronger, and that the force that broke the tooth in the first case, would encounter a much tougher tooth and be far less unlikely to break in that spot on a second time.
Мало того что обломало ось еще и повело искры не равномерно пошли а станок хотя и новый передачи ремнем перебрасываются значит на панели их нет бедные людишки 😊
THIS IS NOT, NOT, C.N.C. MACHINING !!! C.N.C. IS COMPUTERISED COMMAND AND CONTROLLED MACHINING BY COMPUTER PROGRAMMING! THESE MACHINING TECHNIQUES ARE TRADITIONAL OLD SCHOOL( MANUAL) MACHINING PROTOCOLS! WHICH ARE EXCELLENT !!! BUT WAY SLOWER! AND THE SPPED FACTOR? SAY IN NORTH AMERICA IS IMPORTANT TO REDUCE LABOR COSTS! OUR SITUATION IN NORTH AMERICA IS NOT, NOT TO BE ENVIED! IT IS HUGELY COSTLY AND EXPENSIVE TO MACHINE ANYTHING IN NORTH AMERICA! THINGS ARE PRODUCED AT LOW PRICES HERE? AT LOW PRICES? ONY WHEN IT IS DONE AUTOMATICALLY? AND IN LARGE MASS PRODUCTION QUATITIES! EVERYTHING IN LIFE? IS A TRADE OFF! ??? BUT ALSO? IN PAKISTANY TERMS OF COST? IT IS STILL ONLY THE PERSONS MAKING GOOD MONEY WITH THEIR MACHINES? WHO WILL HAVE THEM REPAIRED OR REBUILT!!! BUT IT IS STLL IMPRESSIVE WATCHING THE CREATIVENESS OF PAKISTANI TECHNICIANS, MECHANICS? AND MACHINISTS!!! kennethzakaib607@gmail.com Montreal Canada May 2024
если смотреть на излом оригинальной оси, то видно что деталь с поверхностной закалкой. середина вязкая, поверхность твердая. Сплав соотвествующий. После ремонта ни о качестве материала ни о термообработке речи нет. Такой колхоз до первой серьезной нагрузки
We start off with a broken CAST IRON housing. It is then threaded and a very loose fitting steel insert is screwed in. This is then welded with 1 run of "Pac Bridge" 6013 welding rod. Note no pre heating, post weld controlled cooling or even the correct welding rods for cast Iron to Steel welding. This weld would have cracked at the casting when it had cooled down. The exact same applies to the steel plate that was very loosely screwed into the other part of the Cast Iron casting. Again welded with 1 run of the ubiquitous "Pack Bridge" 6013 welding rod. This is yet another in a very long line of pure "Click Bait" videos with a bodged "Repair" that will never be fitted to any vehicle
IDK, maybe they just sell it, so it's not their problem? Also, many heavy machinery and railroad parts are cast steel, which is more expensive, but can be welded. they def did not make enough passes tho. ps: i am not a welder, so...
@@arthurmario5996 - any weld is a compromise as compared to the strength of an original part. If a 30 or 40 mm shaft can break on load, do you think a generous 10 mm weld will hold and give the same performance??
Me gustan sus videos pero lo que no me gusta es que inician casi con un minuto del vídeo y luego se regresan y vuelven a empezar 🤔🤔 háganlo bien desde el empiezo y no así ok? Saludos de México 😊
Chromed rod hmm. Check out cutting edge engineering they are the best for this sort of thing. They always send the rod to be rechromed. Interesting comments below. Maybe they did replace it anyway. Cheers from Australia. First time I have commented about your work practices.
Repairing this axel in the same method as before is obviously a patch more than a repair as the break occurred at the same point as the previous repair.
A flourishing repair industry, flourishing due to overloading. A similar situation was prevalent in India,but due to crackdown, by the authorities, less prevalent now.
