CNC is a numerically controlled machine tool, and the engraving machine is a part of the machine tool. There is no relationship between the two.
CNC (Numerical Control Machine Tool) is the abbreviation of Computer numerical control, which is an automatic machine tool controlled by a program. The control system can logically process the programs with control codes or other symbolic instructions, decode them by the computer, so that the machine tool executes the prescribed actions, and the blanks are processed into semi-finished parts through tool cutting.
Compared with ordinary machine tools, CNC machine tools have the following characteristics:
●High processing precision and stable processing quality;
●Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed;
●When machining parts change, generally only need to change the numerical control program, which can save production preparation time;
●The machine tool itself has high precision and high rigidity, can choose favorable processing dosage, and high productivity (generally 3~5 times of ordinary machine tools);
●The machine tool has a high degree of automation, which can reduce labor intensity;
● Mass production, product quality is easy to control;
●The requirements for the quality of the operators are low, and the technical requirements for the maintenance personnel are high.
