Types of 4 Axis Milling CNC Controllers
An intelligent device called the 4 axis milling CNC controller is in charge of regulating the operation of the CNC equipment by giving the machining instructions and commands. Different types of 4-axis CNC controllers can be classified according to their functional characteristics.
- Simple controllers: They are the kind of controllers that operate at most tasks with just buttons and different screen menus. These typically have a little more than a handful of workkeys to complete their work. Nowadays, they are often obsolete or are only used in very basic machinery models.
- 2D controllers: Compared to simple ones, these types of controllers are designed specifically to control CNC machines with a 2D processing capability. They usually include a graphic display that can show the machining path or program of the machine, and they can also have features like editing, mirroring, zooming in and out, etc. For better control and programming of the device. As the name suggests, a 2D controller cannot perform 3D processing tasks, limiting its control to two-dimensional spaces.
- 3D controllers: These advanced controllers allow not only 2D but also 3D processing. They have more advanced graphic displays and functions, enabling them to control CNC machines more complexly and precisely. In addition, 3D controllers usually have more memory capacity and faster processing speed, allowing them to handle larger and more complex machining programs.
- Touchscreen Controls: As mentioned previously, the panel serves as the machine's command and control center. Included in this formidable task are the buttons and switches used to change the mechanical and electrical settings of the device. Touch-screen controllers have an LCD (Liquid Crystal Display) that allows the operator to interact with the device through a graphical user interface (GUI). This system is user-friendly so that hovering over an icon takes action rather than using a keyboard and mouse to run the program. The operating system can be Windows, Linux, or a different OS tailored to CNC machines. Controllers with a touch screen may or may not have a controller integrated with the touch screen, which may be reproduced as a physical button.
- PC-based controllers: PC-based CNC controllers are open-loop or closed-loop controllers designed to work with a personal computer. They include a motion control card/software combined with a powerful CPU (Central Processing Unit) for executing motion control algorithms and typically feature high-speed communication buses for connecting various devices and networks. This type of controller generally provides a flexible, high-precision, and easy-to-expand control solution, and it may support complex motion control and high-speed data processing functions.

Maintenance of the 4 Axis CNC Controller
Usually it is only the 4 axis CNC machine parts that have to be maintained regularly, because the controller is not moved or does not become dirty with outside elements. Hence the parts of the controller that need to be cleaned and maintained are usually tight internal spaces that have user interface buttons, screens, emergency buttons, dials and other similar parts. These connecting devices, wires and ports are usually covered with dust and grime and need to be cleaned to ensure the proper functioning of the device.
Overall machine maintenance would include the following:
- Dust Removal: Make sure the dust is free from the keypad, front panel, LCD screen, knobs, and emergency stop button. Compressed air or dust brushes can be used to achieve this. Pay particular attention to removing dust from the controller's slots and cable connectors.
- Connector Cleaning: Over time, the machine's connections and cables may corrode or have debris build-up. Disconnect the cables methodically, and clean the connectors using a tiny brush with some isopropyl alcohol. Ensure they are completely dry before securely reconnecting them again.
- Controller Housing: Use a clean, slightly moist cloth to wipe the exterior surface of the CNC controller housing. This gets rid of any dust or debris without using excessive water, which could harm internal parts.
- Regular Backups: Save the CNC program files and settings to a separate storage device or computer at regular periods to protect against data loss. This ensures that the programs can be reinstated if the controller encounters any issues.
