    Hey, that is a router or end mill cutter, right?

    It's a CNC router. It can accept end mills, drills, vee bits, or just about any circular cutting tool with a 1/2 or smaller shank that can safely spin at up to 24000 rpm. The speed control on this one is a three phase inverter variable frequency drive that loses a lot of torque at lower speeds. This spindle motor isn't usable at all below 18,000 RPM and I normally cut everything at full speed, 24000. The motor is 220 volt, three phase, and is rated at 2.2 hp.

    Here's another video of the same machine.

    Fred: That machine is WAY COOL! I had no intention of speeding up the video, it was awesome.
