    And for what do we use carbide plates?

    Carbide metal is what we use for tooling to cut metal in machines like lathes and mills, and most specifically CNC lathes and mills. It will next be sintered to fuse the particles together to make an ultra hard piece of metal which can now be ground to whatever shape you need. Usually a turning insert or drill. Common industries would be aerospace or medical parts and instruments. For example, the vast majority of metal parts on an airplane are made on a CNC, which uses carbide to cut the metal. You can google something like “CNC machine in use” or something like that to get an idea of what it looks like.

    I do this everyday. Been in the aerospace industry making parts that have gone to pretty much every top aerospace company in the US.

    I know what carbide is, but the way they are making these carbide plates they are pressing, is that how they make the carbide teeth for my circular saw blades? If so, that is really neat.

    It's the first step yeah. Its still has to be heated so it fuses more, and then shaped into the cutting edge.

    That makes a lot more sense. Pressing some dust might not fare well slamming into wood to cut it at high RPMs.

    Thanks for the explanation. But,…That must crumble easily, it’s just been compacted by some pressure. Or does it always need to sintered after this step?

    He said in the explanation it needs to be sintered next. Not that I have any idea what that sintered means lol

    How do you shape carbide metal then? That's so interesting, what is stronger than strong lol

    I thought inserts are usually pressed individually, not ground from a plate.

    Diamond wheels.

    Ohh, yeah! It's used for armor plating. Easily replaced, and tough. I did need to look it up though.

    Tooling. We use carbide dies that have a similar overall shape but a hole with a notch cut into it to press parts. I have no clue how they are made, except that they use some fancy wire cutting method to cut the hole in the die.

    Yes Omg there are regulations for this. This is not safe at all. These presses usually have straps that pull the hands away when it comes down. I could barely watch that.

    No, your worry was completely reasonable! This person is as dense as that carbide keeping their hands there like that.

    Pretty sure these need to get heated up after (sintering)

    "Gently pressing it" is funny, a hydraulic press uses a tremendous amount of force.

    it's also just compressed powder until it goes into a kiln to be sintered together.

    It gave me the willies seeing hands under the press in operation. I know the press is controlled and all that, but things do break.

    They are fired to sinter them afterwards, this isn't the entire process.
