Machine Control Unit (MCU)
The Machine Control Unit is often referred to as the brain of the CNC machine. It reads the CNC program and converts the programming instructions into electrical signals. These signals control the movement of the machine’s components, coordinating the actions of the drive system and the machine tool.
Drive System
The drive system is responsible for moving the machine components along the desired axes. It typically consists of:
- Servo motors or stepper motors
- Ball screws and lead screws
- Amplifiers or drive controllers
This system ensures that the machine moves accurately, allowing the cutting tool to shape the workpiece precisely. High-quality Mitsubishi servo motors are often used for their reliability.
How Does the Machine Control Unit (MCU) Work?
The MCU processes the programming instructions into the machine, interpreting the commands and controlling the movement of the machine parts. It ensures real-time coordination between the drive system, machine tool, and feedback system.

The Importance of Each Component in CNC Machines
Every component in a CNC machine contributes to its overall functionality. The synergy between the machine control unit, drive system, input device, and feedback system allows for the precise manufacture of complex components.
Machine Tool and Spindle
The machine tool, including the spindle and cutting tool, physically shapes the workpiece. The spindle holds and rotates the cutting tool, while the drive system moves it along the programmed path.
Control Panel and Display Unit
The control panel, often featuring a Mitsubishi HMI, includes the display unit that shows the machine status and allows operators to monitor and adjust operations.
Auxiliary Systems
- Coolant System: Keeps the cutting tool and workpiece cool during machining.
- Tool Changer: Automatically switches tools when different machining processes are required.
