CNC(Computerised Numerical Control Machine)is a kind of automatic Machine tool equipped with program Control system,which is mainly used for large-scale machining parts.

Compared with ordinary machine tools,CNC has the following characteristics:

●High machining accuracy,with stable processing quality;

●Can be multi-coordinate linkage,can process complex shapes of parts;

●machining parts change,generally only need to change the numerical control program,can save production preparation time;

●Machine tool itself high accuracy,rigidity,can choose the favorable processing amount,high productivity(generally 3~5 times of the ordinary machine tool);

●Machine tool automation is high,can reduce the labor intensity;

●Higher quality requirements for operators and higher technical requirements for maintenance personnel.
