An Overview of Vertical vs. Horizontal Milling | Precise Tool
Bed Mill: A bed mill can only move the material along the horizontal axis. In this type of milling machine, the spindle is restricted to the vertical axis but can move up and down as needed. The movement of the spindle combined with the horizontal movement of the bed allows milling of a wide variety of shapes and depths.

Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
