I worked for a short while for a company that sold and serviced restaurant and commercial kitchen equipment. Worked on a couple of Hobart VCM's when I was there. VCM is "Vertical Cutter Mixer, essentially a large food processor. A large stainless bowl with some scary looking curved blades at the bottom, driven by a 5HP 3phase motor. It had an interlock switch to hopefully prevent it running with the cover open, but it was still a pretty intimidating machine.
