Vertical milling machines may be provided with tilting heads, allowing the spindle to be adjusted at any angle from vertical to horizontal, to produce surfaces and shapes at odd angles on complex parts. The best known of these is the 'Bridgeport' head, where the head spindle and motor form a unit which can be angled in one, or sometimes two, planes.

Several slow passes over the material may be needed to manufacture the desired shape. UPMILLING. The safest way to machine a piece of metal using a horizontal miller is to feed the metal into the cutter, against its rotation. This is called upmilling and it is the technique used in school workshops. The metal must be held very firmly in a large machine vice, usually a nylon or leather mallet ...
· What is A Milling Machine? The milling machines are used to remove metal from the workpiece to get the desired shape with the help of a revolving cutter called known as a milling cutter. This is used on flat, rough, and irregular surfaces and it is completed by place the workpiece opposite the rotating milling cutter.
· A milling machine is an equipment used during metal cutting to produce parts of various shapes and sizes. Milling machine follows certain steps, in which the different parts work in conjunction with one another, and the end product is a machined part.
