Carbide insert manufacturing process... WOW

Very cool vid on how carbide tips are manufactured.

Great Post!

Amazing what it takes to make one and how cheap they are. Inserts typically have 2, 3, or 4 cutting surfaces making them even more cost effective.

Be cool to see how ceramic inserts are produced, they are really high temp cutters.

Love the idea of meta-making. The tools to make the tools to make the products.

Nice post Paul. I saw this come across my email from YouTube this am, there were other videos that I wanted to watch first. I didn’t realize we could recycle them.

Great video. Would like to know total hours to make.

When I saw “Northmen” I was expecting Vikings! Gap toothed, fur wearing, beating metal, drinking mead from horns with raiding buds, then a little trip in the Long Boats to test it. Not some artisan tool makers fine craftsmanship that probably ends up in L.L. Bean hippster’s hands that goes to tree lot with kiddie “showing him how it’s done.”

I realize am warped … but come on, does “Northmen” conjure up some dude in a quaint cabin? We neither. I mean, someone named “Erik”, Nordic in features and berserker in statue, links to Northmen. I need alcohol to justify being mislead this badly and easily.

This is a video of Sandvik’s new Prime Turn inserts that go against everything I was taught to do. I programmed a demo for a machine in our office that used 2 turrets to turn a shaft simultaneously.

This is a ceramic end mill. I’ve held one of these before and was shocked how light it was. Amazing technology.

I’m not sure if a “thank you” is appropriate or a “dammit” for posting the great mesmerizing videos that have lead me to watch them like a chain smoker this evening after work !
thanks!

You’re welcome. Machining porn is my specialty. :sunglasses:

This analogy is the same reaction I had when seeing/feeling the difference in steel brake rotors vs carbon ceramic brakes on a GT3 a few years ago.

Amazing how hot they can get - no coolant and the cutter doesn’t fail.

Ditto on the brakes Tom references; dimensionally stable at temps that would melt cast iron, and light as feathers. They were a game changer. And the real coup d’etat, work acceptably on the street AND the track. No easy feat with brakes…

Nice machining videos :+1:

As a ceramist thats done a lot of the processes show, the one part I’m curious about is what kind of media they are using in their mills. How do you mill down the second hardest material?

With the hardest- diamond.

Probably diamonds or just rely on ceramic media. They will wear out being the same hardness but if made of the same formula it would not be a problem.

I know in milling chemicals for fireworks they have to worry about contamination of the media wearing away into what you are milling.

Used to be John Neeman tools. Guess they merged with some other maker earlier this year thus the branding change.
