Milling is the process of machining flat, curved, or irregular surfaces by mounting the workpiece to a slotted table and feeding against a rotating cutter containing a mutiple cutting edges.
A milling machine is a machine tool used to machine solid materials. The milling machine consists basically of a motor driven spindle, which mounts and revolves the milling cutter, and a reciprocating adjustable worktable, which mounts and feeds the workpiece.Milling machines are often classed in two basic forms, horizontal and vertical, which refers to the orientation of the main spindle. Both types range in size from small, bench-mounted devices to room-sized machines. Unlike a drill press, which holds the workpiece stationary as the drill moves axially to penetrate the material, milling machines also move the workpiece radially against the rotating milling cutter, which cuts on its sides as well as its tip.
Milling machines can perform a vast number of operations, from simple (e.g., slot and keyway cutting, planing, drilling) to complex (e.g., contouring, diesinking). Cutting fluid is often pumped to the cutting site to cool and lubricate the cut and to wash away the resulting swarf.
Milling machines are use commonly used to mill metal surfaces to exact measurements and bore holes to precise diameters. At Harbor Freight you’ll find high-quality milling machines, metal lathes, clamps and boring heads at discount prices. Our boring bars, carbide cutters and live centers make most metal lathes spring to action with precision and accuracy. Milling machines are basically classified as vertical or horizontal. These machines are also classified as knee-type, ram-type, and bed type.
Knee-type milling machines have a vertically adjustable worktable resting on a saddle which is supported by a knee shaped massive casting that rides vertically on the milling machine column and can be clamped rigidly to the column in a position where the milling head and milling machine spindle are properly adjusted vertically for operation. Vertical milling machines have a spindle located vertically, parallel to the column face, and mounted in a sliding head that can be fed up and down by hand or power. Some mills are designed so the entire head can also swivel to permit working on angular surfaces. Lagun comes with a tilting table. Lagun horizontal mills offer an optional multi-angle milling head for complex compound angle work.
