Introduction of Milling (machining)
Milling is the machining process of using rotary cutters to remove material from a workpiece by advancing (or feeding) the cutter into the workpiece at a certain direction. The cutter may also be held at an angle relative to the axis of the tool. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.
Types of Milling Machines
Knee-Type milling machinesemploy a vertical workspace supported by a knee, which is an adjustable vertical casting. The knee supports a saddle and can be adjusted to allow for a customizable workspace.
Over Arm / Overhanging Arm of Heavy-duty Horizontal Milling Machine
Over Arm / Overhanging Arm of Heavy-duty Horizontal Milling Machine is a horizontal beam present at the top face of the column. Over Arm / Overhanging Arm of Heavy-duty Horizontal Milling Machine may be a single casting which slides on the dovetail ways present on the top face of the column.
The overarm is used to fastened arbor support. Over Arm / Overhanging Arm of Heavy-duty Horizontal Milling Machine may consist of one or two cylindrical bars which slide through the holes in the column.
Horizontal Milling Machine Construction
 The main part of Horizontal Milling Machine is base, Column, Knee, Saddle, Table, Overarm, Arbor Support and Elevating Screw.
1. Horizontal Milling Machine Base: It gives support and rigidity to the machine and also acts as a reservoir for the cutting fluids.
2. The Mill Column: The column of Horizontal Knee type Milling Machine is the main supporting frame mounted vertically on the base. The column is box shaped, heavily ribbed inside and houses all the driving mechanisms for the spindle and table feed.
3. The Mill Machine Knee: The knee is a rigid casting mounted on the front face of the column. The knee moves vertically along the guide ways and this movement enables to adjust the distance between the cutter and the job mounted on the table. The adjustment is obtained manually or automatically by operating the elevating screw provided below the knee.
4. The Mill Machine Saddle: The saddle rests on the knee and constitutes the intermediate part between the knee and the table. The saddle moves transversely, i.e., crosswise (in or out) on guide ways provided on the knee.
5. The Mill Machine Table: The table rests on guide ways in the saddle and provides support to the work. The table is made of cast iron, its top surface is accurately machined and carriers T-slots which accommodate the clamping bolt for fixing the work. The worktable and hence the job fitted on it is given motions in three directions:
. Vertical (up and down) movement provided by raising or lowering the knee.
. Cross (in or out) or transverse motion provided by moving the saddle in relation to knee.
. Longitudinal (back and forth) motion provided by hand wheel fitted on the side of feed screw.
7. The Milli Arbor support: The arbor support is fitted to the Overarm and can be clamped at any location on the Overarm. Its function is to align and support various arbors. The arbor is a machined shaft that holds and drives the cutters.
8. The Milli Elevating screw: The upward and downward movement to the knee and the table is given by the elevating screw that is operated by hand or an automatic feed.
Elevator milling machine
There are universal, horizontal and vertical, etc., mainly used for processing small and medium-sized parts, the most widely used.
Single-column milling machine and single-arm milling machine
The former horizontal milling head can be moved along the column guide rail, and the table can be fed longitudinally; the latter vertical milling head can be moved horizontally along the cantilever rail, and the cantilever can also be adjusted along the column rail. Both are used to machine large parts.
Definition of the milling machine tools
FORTUNE PACIFIC milling machine mainly refers to a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Usually, the milling cutter mainly moves in a rotary motion, and the movement of the workpiece and the milling cutter is a feed motion. It can process planes, grooves, and various surfaces, gears, and so on.
Composition of the milling machine tools
FORTUNE PACIFIC milling machine is a machine that mills a workpiece with a milling cutter. In addition to milling planes, grooves, gears, threads and spline shafts, milling machines can also process more complex profiles with higher efficiency than planers and are widely used in the mechanical manufacturing and repair departments.
Product usage of the milling machine tools
FORTUNE PACIFIC milling machine is a versatile machine tool that can machine planes (horizontal, vertical), grooves (keyways, T-slots, dovetails, etc.), splitting parts (gears, spline shafts, sprockets) on the milling machine. Spiral surfaces (threads, spiral grooves) and various curved surfaces. In addition, the mill can also be used to process and cut the surface of the rotor and the inner hole. When the milling machine is working, the workpiece is mounted on the workbench or the indexing head and other accessories. The milling cutter rotates as the main motion, supplemented by the feed motion of the worktable or the milling head, and the workpiece can obtain the required machining surface. Due to the multi-edge interrupted cutting, the productivity of the milling machine is high. Simply put, milling machines are machines that can mill, drill and boring workpieces.
