Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece. This may be done by varying directions [2] on one or several axes, cutter head speed, and pressure. [3] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy ...
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Tandem rolling mill. Sketch showing a payoff reel (un-coiler), an entry bridle, 2 stands, an exit bridle, and a coiler (tension reel). A tandem rolling mill is a rolling mill used to produce wire and sheet metal. It is composed of two or more close-coupled [clarification needed] stands, and uses tension between the stands as well as compressive ...
A three roll mill or triple roll mill[1] is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it. The three-roll mill has proven to be the most successful of the ...
A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. A male member of conical form (that is, with a taper) fits into the female socket, which has a matching taper of equal angle. Almost all machine tool spindles, and many power tool spindles, have a taper as their primary method ...
A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber from one end, and passes out the other end as a slurry. Both types of mill include liners that protect the cylindrical structure of the mill from wear.
Multiaxis machining. A 5-axis water jet cutter and a part manufactured with it. Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting.
Polygonal turning allows rapid production and clean machining of advanced geometries. The polygon turning unit has a multitude of inserts, and is synchronized so that when an insert cuts the turning bar stock, it cuts the bar at the same radial position each time the workpiece rotates. This enables geometries such as hexes, squares and flats to ...
