Dalian has made great achievements in the development of automatic processing equipment, but there are still serious problems such as low added value and weak competitiveness of mechanical products, and high-end mechanical products still rely heavily on imports. Insufficient product innovation and quality problems are the main reasons for this situation. Modern advanced manufacturing technologies such as CAD / CAM, FMS, CIMS, agile manufacturing and intelligent manufacturing are all based on NC technology. By developing numerical control technology and establishing numerical control machine tool industry, all industrial developed countries in the world have promoted the mechanical processing industry to step into a new historical development stage, which has brought great changes to the structure of the national economy.

Specialized division of labor mode, machining mode and management mode, social production division of labor and enterprise operation mechanism have brought profound changes. The related industries based on it are important basic industries related to the national strategic position and reflecting the level of national comprehensive national strength. Its technical level has become an important symbol to measure the level of a country's industrial modernization. It is especially suitable for processing complex shapes and parts and flexible production of small, medium-sized batches and varieties.

Therefore, it has become an important basic equipment of modern advanced manufacturing technology and a color flow product in the world machine tool market. The popularization of CNC machine tools will bring great changes to modern manufacturing technology. The development of CNC machine tools in industrial developed countries has generally experienced three stages: slow, fast construction and guaranteed development. At present, it has reached a high level and is fixed on the table. This is a tooling.

Maybe this tooling also needs electronic control, hydraulic components, pneumatic components, etc., which constitutes a tooling with high precision and high automatic control. Lifting device and indexing device, etc; Chip treatment is generally completed by scraper and screw conveyor. This machine tool also realizes the whole processing cycle of a single process. Rigid automatic production line is a multi station production process. It uses the workpiece conveying system to connect various automatic processing equipment and auxiliary equipment in a certain order to complete the processing of single parts under the action of the control system.
