Evaluate the technical performance of the machine can be attributed to the ultimate indicator of precision and productivity. Comprising a workpiece machining accuracy dimensional accuracy, shape accuracy, positional accuracy, surface quality and accuracy of the machine tool retention. Productivity involves cutting time and auxiliary time, as well as the degree of automation and reliability of the machine. These indicators depend on the one hand, the static characteristics of the machine, such as static geometrical precision and rigidity; on the other hand with the dynamic characteristics of the machine, such as a greater relationship between motion accuracy, dynamic stiffness, heat distortion and noise. Supplementary motor includes adjustment tool or workpiece fast approaching and exiting, machine parts position workpiece indexing turret indexing, send folder expected multi-axis drilling equipment, start, speed, change direction, stop, and automatic tool change, etc. movement. As a cornerstone of modern industrial machine tool industry drilling equipment manufacturers, industrial economic development process in any case can not bypass a critical issue, Chinese machine tool industry as a result of deficiencies, has been in the high-end machine development projects fall in foreign mainstream level, is in a catch-up process. China CNC machine tools is still lagging behind. China CNC machine tool market is huge drilling equipment, compared with foreign products, China's shortfall is adjustable drilling equipment, China is in the middle of industrialization on the machine's high speed and efficiency and precision, that is, to solve the shortage mainly from the gradual opening up to the building economic power shift, a group of strong transition from poverty to prosperity, coal, automobile, steel, real estate, building materials, machinery, electronics, chemicals, and other heavy industry-based, high-growth industry momentum, constitutes a machine tool CNC machine tools market, especially huge demand.
