Grinding a tool with chipbreaker is important swarf is potentially dangerous for the machinist and potentially ruin a tool ..live centre would also go a long way.If one of my apprentices had chucked precision freshly machined component on the floor he might need to see protoligist.

[@seanjournot7115]

These are hacks not experts. I can't believe they are throwing parts on cement like that. They either don't know how or don't have the ability to measure pitch diameter on helical gears. These gears won't last long either; gears need to be rough cut, hardened, then ground to their finished dimensions. It's also a good idea to print gears in an assembly to verify proper alignment.

A completely standard bit of machining, which any competent machinist can do. We used to have 1000's of them in the Uk until our government decided we didn't need to make things anymore. The complete lack of precision measuring tools is amazing, and those gears will need to be hardened and tempered and then finish grinding before use, otherwise, it is complete crap.

As a machinist I must say, this sh*t is painful to watch. The machines are as abused as the people using them, the material is mild steel, concentricity is about ten thou TIR and that tooth profile is BULLSHIT. When the center to center dimensions weren't right he just put that piece of crap back in and fed the cutter further in...I wouldn't pay ten cents for it...it's just going to kill its mate. Maybe he made that too...

[@KkoLIK]

[@selmirikanovic]

There is definitely something wrong with that gear. I can not count the exact number of teeth but there are surely more than 17 so teeth ends must not be that sharp (gears with less than 17 teeth must be corrected in order to avoid undercutting). They made the wrong pitch diameter so he simply did another pass to "fit it" and ruined the gear by undercutting the teeth. Not to mention the throwing the finished piece on the floor....

They must have terrible accidents, the sandals, swarf, over extended machining the list goes on but they seem to get there and has been said below how long the parts will last. I recall going back 50 years when the UK was giving up Engineering all the kit that got us through the second world war was shipped out to India in ship loads and it's got them to where they are today and tomorrow they will eventually get to where we are today so respect there. Also respect to our fathers who made that kit and it's still running.

no coolant and low feed rate/ shallow depth of cut. He's using a very sketchy lathe; I bet the spindle bearings are shot. It sucks but with a low rigidity setup with no coolant that's what you get. He's also hand grinding his tools, he may be able to get chips with a negative rake but I doubt they would be figure 9's.

Yes guys, the health and safety is gravely ignored in Pakistan. I have actually seen a live accident 15yrs ago in a construction area, purchasing stuff from a shop across the road with my uncle. The 50+yr old worker was giving directions to a tractor and trolley driver fully loaded with coarse aggregate and was standing between a brick wall and the rear of the tractor. The tractor got a bit stuck and the guy pushed the accelerator which suddenly reversed the tractor more than it needed to. The guy behind had no time to react and was pinched between the wall and a small corner of the trolley/trailer. All of us ran to help but there was nothing we could do. I was 13 still remember everything. The mentality is get the job done as easily/quickly as possible, not as safely/efficiently as possible.
