Here are some of the parts that make up a CNC milling machine
1. A computer with a microprocessor and a control unit. The control unit usually has a motherboard and an interface board, which allows it to talk to other components on the machine
2. An electronic drive for moving the tool or cutting tool
3. A spindle that turns the workpiece during milling operation, or sometimes during other operations, such as drilling or turning
4. A spindle motor that supplies power to the spindle, which is connected to the spindle via a gear train or belt drive system
5. A feed system that moves material along a table in front of the machine's cutting tool(s).
