bed-type milling machine

A bed-type milling machine is a production milling machine designed for repetitive operations. Unlike standard knee-and-column designs, its sliding table is mounted directly onto a massive bed and moves only longitudinally. The spindle head can be adjusted vertically to set the depth of cut. These machines often feature automatic controls, allowing less-skilled operators to load parts and start the machining process, with one part being machined while another is being unloaded and replaced. Milling machines, in general, use a rotating cutter with multiple cutting edges to shape a workpiece, which is typically held in a vise on a movable table.123
