CNC mill is a type of automatic milling machine with CNC (Computer Numerical Controlled) controller to cut 2D/3D shapes or mill patterns on various materials. CNC milling is a computer numerical controlled machining method similar to engraving, cutting, boring, and drilling, and able to achieve many of the operations performed by CNC router machines and boring machines. CNC mill uses a rotating cylindrical tool, which is able to move along multiple axis, and can create a variety of shapes, slots and holes. In addition, the workpiece is often moved across the milling tool in different directions.
CNC milling machine is one of the most common types of CNC machines. Typically, they are grouped by the number of axis on which they operate, which are labeled with various letters. X and Y designate horizontal movement of the workpiece (forward-and-back and side-to-side on flat surfaces). Z represents vertical, or up-and-down, movement, while W represents diagonal movement across a vertical plane. Most large format and small size mini mills offer from 3 to 5 axis, providing performance along at least the X, Y and Z axis. High end automatic milling machines, such as 5 axis CNC mills, require computer numerical controlled programming for optimal performance due to the incredibly complex geometries involved in the automatic milling process. These equipments are extremely useful because they are able to produce shapes that would be nearly impossible using manual tooling methods. CNC mills also integrate a machine tool for cutting fluid pump to the tool during machining.
Computer numerical controlled mills are used to generate a variety of components, and tooling costs involved have continued to become more affordable. Generally, large manufacturing runs requiring relatively simple designs are better served by other methods, although CNC machining can accommodate a wide range of manufacturing needs. CNC mills are ideal solutions to everything ranging from prototyping and short-run production of complex parts to the fabrication of unique precision components.
Basically remove material that can be sculpted or cut can be machined by an automatic mill, although a lot of the work done is performed in metal. As with engraving and cutting, the right mills must be selected for every type of material in order to avert possible issues. The hardness of the material, as well as the rotation of the mill must all be factored before start machining process.
CNC mills are commonly classified as being vertical or horizontal to indicate the axis of the spindle. These machines are also classified as ram types, knee types, planer types, and manufacturing or bed types. Most automated mills have complete computer numerical controller, variable spindles, electric drive motors, coolant systems, and poweroperated table feeds. CNC mills are divided into vertical milling machines, horizontal milling machines, turret mills, bed mills, multi-axis (3 axis, 4 axis, 5 axis) mills.
CNC mills are used for engraving, carving, milling, cutting and drilling most metal materials, including copper, aluminum, steel, iron, brass, as well as nonmetal milling includes wood, foam, and plastics. It is widely used in injection mould, ironware mould, metal molds, shoe mold, drop mold, clock parts, zinc electrodes, copper electrodes, automotive, metal electrodes, metal crafts, jade, metal arts, jewelry, dental crown, and other molding industries. It is especially designed for batch milling molds, watch, eyeglasses, panel, brand, badge, outside surface's sleeking, 3D graphics and words, It’s easy for this mill to form 2D or 3D relieves on a wide range of materials.

Features & Advantages
CNC mills feature with high precision, user friendly, high cost effectiveness, stable and reliable machining quality, which can mill complex and 3D curved parts. It can perform drilling, reaming, boring, tapping, milling, grooving for box parts.
As the integration density of the summary line is increased, the hard connection of the components of the numerical control and the driving device is reduced, and the welding points, the connection points and the exterior are continuously reduced, thereby greatly reducing the failure rate.
Since the computer numerical controlled system hardware is universal and standardized, for the control requirements of different machines, it is only necessary to change the system control program in the programmable read-only memory. At the same time, due to the modular structure, it is also convenient for the expansion of system functions.
The adaptive part, so-called flexibility, is the adaptability of the exponentially controlled machine to change with the production object. Product processing is carried out on computer-controlled equipment. When the product changes, only the input mill program can be changed to meet the production needs of the new product. There is no need to change the hardware of the mechanical part and the control part, and the production process is automatically completed. This feature not only satisfies the market competition needs for fast product updates, but also solves the problem of automated production of single-piece, small-batch, and variable products. Strong adaptability is the most prominent advantage of computer-controlled equipment, and it is also the main reason for the emergence and rapid development of computer-controlled equipment.
After the use of VLSI, the size of the cabinet box is reduced, the programmable interface is used, and the logic circuits of S, M, T (spindle transfer control, auxiliary function and tool parameters) and other sequential control parts are combined with the Nc device. Therefore, all the control boxes are entered into the machine, which reduces the floor space and facilitates the management of the equipment.
Things To Consider
1. In automatic milling machine operations, wear work clothes, tie the big cuffs tightly, and tie the shirt under the trousers. Female students should wear hard hats and put the braids in the hat. It is not allowed to wear sandals, slippers, high heels, vests, skirts and scarves to enter the workshop;
2. Be careful not to move or damage the warning signs installed on the machine;
