1, the parts within the size of the machine can be processed 2, CNC turning is a batch of advanced processing method is said to be the same as the ordinary lathe, but its biggest advantage is: reduce manual operation (originally an automated machine tool with CNC operating system. The CNC system can be logically processed with Control the program specified by the code or other symbolic instructions and decode it so that the machine can move and machine the part) 3. High processing precision and stable processing quality; 4, can carry out multi-coordinate linkage, can process parts with complex shapes; 5. When the machining parts are changed, generally only need to change the NC program, which can save production preparation time; 6. The machine tool itself has high precision and rigidity, and can choose favorable processing amount, and the productivity is high (usually 3~5 times of ordinary machine tools); 7, the machine tool is highly automated, can reduce the labor intensity; even can automatically feed, greatly reducing labor costs. 8. The quality of the operators is high, and the technical requirements for maintenance personnel are higher.
