Jig borer

A jig borer is a machine that helps people make very precise cuts in metal. It looks like a big, fancy drill with some extra parts. The machine can move the metal around and make sure it's at the right spot for cutting. Think of it like a game of Operation, but instead of trying to avoid touching the sides, the machine is carefully cutting the metal without touching anything else. This is important because metal can be very hard and tough to cut, so a jig borer makes sure it's done exactly right.
