2. What does the structure of a CNC cutting machine include?

Metal CNC cutting machines usually consist of main components such as the control unit, machine table, drive system, axis motors, cutting head, and cooling system. Depending on the machine model and cutting technology, the equipment may be integrated with additional hydraulic systems, pneumatic systems, or other operational support assemblies.

2.1. Control unit

This is the control center for the entire operation of the CNC cutting machine. This unit receives data from drawings or pre-programmed programs, then controls the machine to move according to the required cutting path.

2.2. Machine table

The machine table is where the material is placed and fixed during processing. The size and structure of the machine table directly affect the ability to cut materials of different sizes and the stability during operation.

2.3. Axis motors

Each moving axis of the CNC cutting machine is controlled by a separate motor, usually a servo motor or step motor. This system helps the cutting head move accurately along the X, Y axes, and in some cases, the Z axis.

2.4. Cutting tool or cutting head

Depending on the processing technology, CNC cutting machines can use plasma cutting heads, oxy-gas cutting heads, laser cutting heads, or mechanical cutting tools. This is the part that directly impacts the material to create cuts according to the design.

2.5. Cooling system

The cooling system is responsible for reducing heat during operation, helping to protect components and maintain the machine's stability. In some CNC cutting machines, this system is particularly important to extend the lifespan of the cutting head and cutting source.

2.6. Hydraulic system

The hydraulic system is not a mandatory component on every CNC cutting machine but often appears in certain machine models or generations. This part supports operational mechanisms related to lifting, clamping, or driving depending on the design of each machine.

3. Popular types of metal CNC cutting machines today

CNC cutting machines are currently classified mainly by cutting technology and processing material. Some popular models on the market include CNC plasma cutting machines, CNC laser cutting machines, CNC oxy/gas cutting machines, CNC hydraulic cutting machines, and CNC water jet cutting machines, each suitable for different production needs.

3.1. CNC plasma metal cutting machine

• CNC plasma cutting machine uses a plasma arc to cut conductive metal materials such as steel, stainless steel, aluminum, and sheet iron.
