    Default Heat sink machine. OT/Interesting

    I thought this was interesting. Skiving.

    I was going to make a shaper joke when I first saw it but it appears to be a modded vmc.

    Wow! I bet it took awhile to get that dialed in. Lots of ways it could go wrong.

    Regards.

    I would have lost some money betting you couldn't do that.

    I don't know the application, but unless there is a fan, those fins are way too close together.

    Yes, there will be a fan.

    Since nobody named the process here, it's "skiving" and it can be super efficient in material with no chip loss.

    Skiving is used in a lot of different applications. Here's the skiving shot for Steel Wool:

    That is really neat. My hat's off to the guy who set it up.

    What really amazes me is that the fins stay straight. I would have thought that they would come off curved, like most chips that we make. I would bet that the exact alloy is an important factor.

    I wonder just how this process compares financally to other ways to make the same product. Is this more efficient? Is it only for small quantities? Less wasted material vs. longer time? Set up time? Wear and tear on what is obviously an expensive CNC machine? Even ball screws will wear and they can be expensive to replace.

    Does it still qualify as "machined from billet"?
