A CNC mill has a table that moves by Computer Numerical Control (CNC), to drill or mill parts that are very accurate and repeatable.
On a CNC mill the material is clamped and the tools are rotated into or against the material to cut into it.
Apart from the first clause, the second sentence describes milling-machines generally, but a further aspect Sale of used CNC machines with transport CNC machines is that the tools are also changed, and the speeds and feeds set, by the code.
The feeds are driven by stepper-motors responding to pulse-trains generated from the control code.
