Horizontal milling machines derive their name from the positioning of the tool – their axis lies horizontally. The images above show one way of using them which is plain milling. Of course, horizontal mills are also suitable for end milling. The build of a horizontal mill is pretty simple. The cutting tool attaches onto the arbor.
The post mill is a windmill supported by a post on which it pivots to catch the wind. It is the earliest type of European windmill. Its defining feature is that the whole body of the mill that houses the machinery is mounted on a single vertical post, around which it can be turned to bring the sails into the wind.

Reinforced concrete (RC) frames consist of horizontal elements (beams) and vertical elements (columns) connected by rigid joints. These structures are cast monolithically— that is, beams and columns are cast in a single operation in order to act in unison. RC frames provide resistance to both gravity and lateral loads through bending in beams
Milling is particularly well suited where a high quality of surface finish is required: frequently in the machining of metallic materials, the desired finish can be achieved in a single pass of a cutter across a surface.
