CNC Milling Machines refers to machine-operated cutting tools that are programmed and controlled by Computer Numerical Control (CNC) systems to exactly separate materials from a workpiece. The last result of the machining process is a particular part or product that is made by utilizing Computer-Aided Design (CAD) software.
Milling Machine Parts And Working milling machine is used to form various types of parts in the industries because it can machine all shape and size work piece. it is used to cut slots, grooves, and drill and perform all operation like to shape the workpiece. the basic milling machine parts are base, column, arbor, knee, saddle, table, overhanging arm, elevating screw, ram etc.
In drilling machine the drill is rotated and fed along its axis of rotation in the stationary workpiece. Different parts of a drilling machine are shown in Fig. 1 and are discussed below: (i) The head containing electric motor, V-pulleys and V-belt which transmit rotary motion to the drill spindle at a number of speeds.

The milling head is the upper part of a vertical mill machine. It consists of spindle, driving motor and other controlling mechanisms. Ram: The milling machine part can move transversely (in and out) on the column by a hand level. One end of the arm is attached to the column and the other ends on the milling head. see my recommendation
Plain Milling Plain milling is an operation of milling machine in which a plane, flat, horizontal surface is drawn parallel to the axis of rotation of the plane milling cutter. This is also called slab milling. Face Milling These types of milling operation are done by a face milling cutter which rotates in vertical direction along the axis of the work surface.
Milling machines are tools used by engineers and machine creators to cut metal into a specific shape. A turret milling machine is a vertical mill, meaning the spindle — the area that performs the cuts — is positioned vertically. The turret milling machine is considered a versatile unit, because it can create a wide array of shapes.
Two popular ram-type milling machines are the universal milling machine and the swivel cutter head ram-type milling machine. UNIVERSAL RAM-TYPE MILLING MACHINE The universal ram-type milling machine is similar to the universal horizontal milling machine, the difference being, as its name implies, the spindle is mounted on a ram or movable housing.
