How many types of CNC machines are there? | Classified by the number of axes of movement

Classified by Number of Axes:

CNC machines are often identified by the number of axes of movement, which affects the complexity of the workpieces they can produce. The basic axes are X, Y, and Z:

• 3-Axis CNC machines: move along the X (horizontal), Y (perpendicular to X), and Z (depth) axes. They are suitable for 2D or 2.5D milling operations.

• 4-Axis CNC machines: have an additional rotation axis (such as an A or B axis), enabling more complex operations.

• 5-Axis CNC machines: have two additional rotation axes, enabling multi-faceted machining of parts in a single operation and the production of complex, free-form shapes.

CNC milling machines and lathes are the two most common types of CNC machines found in the manufacturing industry.

How many types of CNC machines are there? | This is the most common classification | Classified by function

Classification by Operation - This is the most common classification:

• CNC Lathe/Turning Machine: Used for turning workpieces that are symmetrical to rotation (e.g., shafts, sleeves, disks). The workpiece rotates and the cutting tool moves to cut off the material. 

• CNC Drilling Machine: Used for drilling cylindrical holes in workpieces with high precision

• CNC Grinding Machine: Used for polishing the workpiece surface to a smooth, precise size.

• CNC Laser Cutting Machine: Uses a high-powered laser beam to cut materials.

• CNC Plasma Cutting Machine: Uses high-temperature plasma to cut conductive materials (e.g., metal).

• CNC Waterjet Cutting Machine: Uses high-pressure water jets. (May contain abrasives) when cutting materials.

• CNC EDM (Electrical Discharge Machine): Uses electrical discharge (sparks) to process conductive materials. Suitable for high-precision machining, such as molds.
