What is CNC machining? What are the considerations in CNC machining?
CNC(CNC machine tool) is an abbreviation of Computer numerical control, which is an automatic machine tool controlled by program. The control system is able to handle the with logic control code or other symbols in accordance with procedures prescribed by the instruction, through the computer to decode, making machine execution action, through the tool cutting blank material processed into semi-finished products production parts.
Compared with ordinary machine tools, the numerical control machine has the following characteristics:
The processing precision is high and the machining quality is stable.
It can conduct multi-coordinate linkage, and can process complex parts.
When the machining parts are changed, it is generally necessary to change the nc program to save the time of production preparation.
The machine tool itself is of high precision and rigidity, which can be used for the processing quantity and high productivity (usually 3~5 times of the normal machine tool).
The degree of automation of machine tool can reduce labor intensity.
The quality of products is easy to control.
