>Ball mill - Wikipedia
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
The Fundamentals of a Vertical Machining Center (VMC)
Through the sharpness of the tool and force of the table pushing the material into the cutter, the material yields and is cut or shaved away as desired. The axis of force can be up/down (referred to as the Z-Axis) left/right (referred to as the X-Axis), or front to back (referred to as the Y-Axis). The Original Milling Machine
>How to use a Milling Machine - Instructions
The plain vise, similar to the machine table vise, is used for milling straight workpieces and is bolted to the milling machine table either at right angles or parallel to the machine arbor. The swivel vise can be rotated and contains a scale graduated in degrees at its base to facilitate milling workpieces at any angle on a horizontal plane.
Description - Massachusetts Institute of Technology
The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, this document will focus only on the vertical milling machine. A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.
