These are insane CNC Machines to me

These are Incredible CNC Machinery Making Crankshafts and this is coming from a Machinist that is very used to CNC equipment too!

As I said I am a machinist that has worked with CNC Turning Centers and CNC Mills of various sizes but, never a CNC station that picks and places the part along the different stations before. This is especially true on the first machining station where the crankshaft forging seem to travel overhead to the next machining stations. One system gang drills the oiling holes in the crankshafts making me wonder how many cranks this machine must output beside the obvious that it doubles it.

There are 2 different style CNC machines making the two crankshafts in this video. One that used huge saw like cutters to rough out the journals and the second using indexing tools instead. The machine in the beginning uses a tool that reminds me of a dado blade that cuts a very wide amount of material at once. Great for cutting the journals but, at the same time with the crank held through centers it is able to cut the crank throw journals at the same times. Not like the old school ways when you offset the crank to do each one individually. The second machine uses indexable tooling to cut the journals more like the machines I worked with although it does not show the crank throws being cut, just the mains I do believe?

Then later there are some large machines making Aircraft landing gear. They are making some incredibly heavy cuts with the coolant turned off most likely for the sake of video recordings. I wouldn’t imagine the cutters to last very long with the heat it looks like they are enduring without some flood coolant. That and I would hate to be the one to look after all the inserts on the other indexing heads turning the crankshaft forgings. These are some big dollar machines to say the least and have to be in the million dollar range to me?
