Compared with ordinary machine tools, CNC technology has the following characteristics:
● high processing precision and stable processing quality;
● it can carry out multi coordinate linkage and process parts with complex shapes;
● when processing parts are changed, generally only the NC program needs to be changed, which can save production preparation time;
● the machine tool itself has high precision and rigidity, can select favorable processing amount and high productivity (generally 3 ~ 5 times that of ordinary machine tools);
● the machine tool has a high degree of automation, which can reduce the labor intensity;
● higher quality requirements for operators and higher technical requirements for maintenance personnel.
