Machining Porn

Machining Porn

Trust me, it gets boring really quick. Don't get me wrong, machining can be fun, but this type of machining, CNC, is unbelievably boring to watch. And on top of that, when it's not a demo for a video like this, the coolant is flying everywhere, and you can't see what's actually happening. It's like trying to watch the brushes through your car windows when going through a carwash. You can't see shit.

It's a ceramic coating to strengthen the tool, usually Titanium Nitride. Those are insert cutters, the tools wear out at a consistent rate, so it's cheaper to replace the tips instead of the whole tool.

Crazy, Don't know why but watching this never makes.me bored

CNC machines are awesome. Worked one for a few summers. Still amazing to see what they can do. The metal spoon will eat your shoes though.

You mean exactly like sex porn and real sex are nothing alike?

What is the yellowish metal at the end of a drill bit?

I don't know about you guys but when this stuff is entirely in slow motion with apocalyptic movie music I kind of lose interest instantly. I'd much rather hear the machines and see how quickly it forms. I love watching craftsmen make stuff otherwise.

JUST THE TIP

The tools we've created as a species are pretty amazing.

Especially once you realize that to build a computer chip from scratch if you landed on a new planet or something you'd first have to build an entire technological civilization from scratch. You need the tools to build the tools that build the tools.

What's with the guy rolling the giant ball at 6:03? Is he polishing it?

I can't believe how perfect that analogy is.

I realize I had a bit of a derp moment there. It's called spoon in norwegian and I somehow felt that was correct for english aswell. We have quite a few borrowed english words, especially when it comes to technical terms.

Engineers are pretty smart. I'd never even considered the idea of just replacing the cutting surfaces on a bit. Then they took it a step further and made it so the cutting surface can be rotated for a new surface so the cutter lasts even longer.

Not only rotated, rotated and flipped. A couple were hexagonal since it cut both flat and on an angle for removal at the same time. Give a single cutting head 5 additional lifetimes. Pretty freaking cool.

I'm going to assume you're talking about the inserts. Those are coated carbide. The yellow is just a surface coating. It helps reduce wear on the tool so you won't have to replace them as frequently.

These tools are whats known as indexable carbide tooling. the yellowish materiel you see at the end is actually a coating that is put on the carbide insert.

Here's a video on how they are made

The metal spoon will eat your shoes though.

If you are programing and running just a few parts or even a single part per run, it never gets boring. Always a challenge.

If you are running a production run of several thousand parts (or more) and are only there to hit the green button and do an occasional inspection, then yeah it's boring.

Actually, quite a few words came the other way with vikings settlements on the British islands. For example : ransack, slaughter, club, knife, (to) die, etc. Ah, good times.

Ahh yes. We surely enriched your culture for some time. At the moment we are saving up money to do a Battle of Stamford Bridge V.2 that we intend to win this time. We just call it "the oil fund" or "Government Pension Fund of Norway", but it's really to fund a massive raid to take back land that is our birthright.

Definitely agree. Nothing is better than meeting a costumer in the morning, them giving you some cocktail napkins of sketches, then drawing it up in CAM, setting up the machine and having a day of both trial and error and huge satisfaction when shit runs flawlessly. I'll never get bored of that process.

The material is a blend of Tungsten Carbide, Cobalt, and other proprietary substrates After sintering it either goes to grinding or straight to finish coating. Coatings are usually TiCN, TiALN, TiN etc. Most inserts have Titanium based coatings and are coated with either CVD (chemical vapour distribution) or PVD (physical vapour distribution) method. Different coatings affect tool life with use on specific materials. They also allow the tool to be operated a lot faster.. I hope that helps.
