HOWEVER, as we pay homage to the mighty mill, did no one else happen to notice the mighty MOUSE!!!???? (final 30 seconds or so?)
|
I wasn't sure what it was but my initial thought was that it was a mouse. I'll have to watch it again.

i wonder what the temp in that room is? or whether the coolant being used contains any harsh chemicals or whatever? maybe the mouse is 'drunk' on it

The temp in the room is probably just standard room temperature unless they are lucky and have air conditioning. And yes the coolant can be harmful if drank, but unless you bathe in it regularly, it is pretty safe. Some people have skin reactions to it, but for the most part most have no problems. The coolant should be checked daily though as it can and does sometimes "sour" and when it does it has a pretty bad odor.

Now, pardon my ignorance, but was that a water jet and also a bit-type of cutting?

Not water jet. A water jet machine uses very high pressure and abrasive in the water to cut. OCC has a new WaterJet machine. It sounds like Powerrodsmike has been around some of these machines.

The 5 axis in the video is really something to watch. I was reading some of the replies about it and someone stated that it actually took 40 different tools and 119 hours of actual run time to produce the machined block. I can only imagine how many hours of programming and how many hours of debugging it took to get a finished item. I program and run a small three axis mill and a small axis mill, and some of the programs for it can rack the brain for a few days. What amazes me is the speed that the tooling runs at. I regularly get Modern Machinst and a couple of other machinist magazines and it is real interesting as to the technology of cutters, speeds, etc. of machining. It has now gotten to the point that there is hardly any vibration in the heads of these machines. Everything is so precise in the way of mating parts, bearings, etc. These machines are now seeing 15,000-30,000 rpm's in cutter speeds and high feed rates to go with it. I would imagine a machine of that type is going to run between $500,000.00-$750,000.00 to purchase, so a person would have to be machining a hell of a lot of aluminum blocks to recoup that kind of shellout. That chunk of aluminum alone was a few thousand dollars in itself.
