High precision: the CNC machine tool works automatically according to the predetermined program, and the working process generally does not need manual intervention, which eliminates the error caused by human factors caused by the operator. When designing and manufacturing equipment, many measures are usually taken to make CNC machine tools achieve high accuracy. At present, the pulse equivalent of the numerical control device can reach 0.01 -0.0001mm, and higher accuracy can be obtained by real-time detection error correction or compensation.
High efficiency: because the CNC machine tool can adopt a large cutting amount, it effectively reduces the cutting hours in processing: the CNC machine tool also has the functions of automatic speed change, automatic tool change and other auxiliary operation automation, and does not need the inspection and measurement between processes, which greatly shortens the auxiliary time; For multi-functional machining centers, almost all parts can be processed after one clamping, which can not only reduce the clamping error, but also reduce the turnover time of semi-finished products. Therefore, compared with ordinary machine tools, the production efficiency of CNC machine tools is many times higher. For the processing of complex surfaces, the production efficiency can be increased several times, or even dozens of times.
