Here’s something you don’t see every day–granite being cut by a giant CNC diamond wire cutter into these exotic shapes for art and architectural use.  Here are some samples of this kind of work:

Pretty amazing work from stone!

And here is the Breton CNC Machine that makes it possible:

As you can see, the machine somewhat resembles a giant bandsaw.  There are two axes of movement enabling it to take slices out of the stone with a diamond coated wire.  For the more ordinary task of slicing a big block of quarried stone into slabs suitable for counter tops and the like, they make multi-wire machines that slice straight down and create many slabs at once.

Before anyone asks, I have no idea what the feeds and speeds should be for a beast like this, but I certainly am curious!

My thanks for making me aware of this machine go out to a web site and blog called Core77.  Their site is dedicated to the art of industrial design and there are many interesting articles there talking about tools and finished designs.  Check them out if you get a chance.
