There are two basic types of vertical centers: turret and bed. Turret vertical mills keep the spindle stationary while the table moves along linear axes to direct the cutting. Bed vertical mills allow the spindle to move along the Yaxis while the table moves along the Xaxis. Horizontal milling centers have the spindle oriented horizontally ...

Milling is a machining process that involves the use of cutting tools that are rotated at a set speed and then brought into contact with a work piece. The work piece is typically held in place by some sort of clamping device. The cutting tools begin to remove material when they touch the work piece. Some materials may require milling to be ...

Mill wheels 'grind' as does a pestle in a pestle and mortar. The definitions of "pulverise" that you give include both "grind" and "pound". This shows that "grinding" and "pounding" are different processes which can contribute to the process of "pulverising" something so "pulverise" is a more general term incorporating both of the others.

Plain milling is also commonly known as surface milling. It uses a horizontal mill, meaning the cutting tool's rotational axis is parallel to the cutting surface. Surface milling can use different cutters, wide or narrow, depending on the necessary outcome. Using a wide cutter can result in fast material removal when coupled with slow cutting ...

The main difference between a lathe and a mill is the relative rotation of the workpiece and the cutting tool. In a milling machine, the workpiece is clamped on the workbench and the cutting tool, which can move up and down, rotates to remove material from the surface. The clamped workpiece can move along the X and Y axes to get the desired cut.
