CNC is the short form for Computer Numerical control. We have seen that the CNC machine works as per the program of instructions fed into the controller unit of the machine. The CNC machine comprises of the mini computer or the microcomputer that acts as the controller unit of the machine. While in the CNC machine, the program is fed into the punch cards, in CNC machines, the program of instructions is fed directly into the computer via a small board similar to the traditional keyboard.

In CNC machine, the program is stored in the memory of the computer. The programmer can easily write the codes, and edit the programs as per the requirements. These programs can be used for different parts, and they don’t have to be repeated again and again.
Compared to the NC machine, the CNC machine offers greater additional flexibility and computational capability. New systems can be incorporated into the CNC controller simply by reprogramming the unit. Because of its capacity and the flexibility, the CNC machines are called as “soft-wired” NC.

Every CNC machining factory must have a CNC machine.
CNC(Computer Numerical Control) machine is also known as automatic machine. It is high precision and high efficiency with intelligent program control system. The control system can process the program that has control code or other symbolic instruction, and decode it, so as to make the machine tool movement numerical control bending machine and process the machining parts. People just need to enter mechanical parts programming code to finish machining parts. So, this shows its advantages, first, it has strong adaptability to the processing object. Second, In this field, as everyone knows its high machining accuracy and stable processing quality. Third, Multimedia axis linkage can be carried out, the shape of complex mechanical parts can be processed. Four, The most important advantage are high productivity and high degree of automation. This is CNC machine.a
