This paper focuses on various types of CNC milling machines and lathes, both of which are widely used in manufacturing processes. CNC stands for "computer digital control," which indicates that the machine is operated by a set of commands sent by the controller. Any machine controlled by this code can be classified as a CNC machine, including milling machines, lathes, and plasma cutting machines. The movement of CNC machines is defined by their axes, such as the X axis, Y axis, and Z axis, with some advanced machines using A axis, B axis, and C axis. Spindle Motor Manufacturer produces both Air Cooled Spindle Motor and Water Cooled Spindle Motor, which are typically utilized in CNC machines with up to 5 axes.

● CNC Lathe – This type of lathe works by rotating material in the chuck of the lathe. Then the tool moves on 2 axes to cut the cylindrical part. CNC lathes can form curved surfaces, while manual lathes are difficult or even impossible to form curved surfaces. Tools are usually non rotating, but can also be moved if they are power tools.

● CNC milling machine – CNC milling machine is usually used to make flat parts, but more complex machines have more degrees of freedom and can produce complex shapes. The material is stationary, the spindle rotates with the tool, and the tool moves along 3 axis directions to cut the material. In some cases, the spindle is stationary while the material moves.

● CNC drilling – This machine is similar to the CNC milling machine, but it is specially designed to cut only along one axis, that is, drill down into the material only along the Z axis, and never cut along the X and Y axis.

● CNC Grinder – This machine allows the grinding wheel to come into contact with the material, producing a high-quality surface. It is designed to remove a small amount of material from the hard metal; Therefore, it is used as a surface treatment operation.
