This document discusses vertical machining centers (VMCs). It provides the following key details: - A VMC is a type of computer numerical control (CNC) milling machine where the spindle is vertical. In a VMC, the workpiece is stationary while the tool rotates. - VMCs can be used for cutting, drilling, engraving, tapping, and other machining applications due to their versatility. They are commonly found in machine shops. - Common milling cutters used in VMCs include end mills, face mills, ball cutters, slab mills, and more. VMCs can perform operations like boring, slotting, dividing, and drilling.
