CNC machine tool development is very rapid

Combined machine tools have developed rapidly in recent years, and manufacturing technologies and complete sets of process equipment with high degree of integrated automation that integrates electromechanical and electrical machinery have been favored by the market. In the current domestic small and medium batch production, the combined machine tool has been widely used due to its advantages of low cost and high efficiency. Especially in the automotive and other industrial production, the combination of machine tools has played a huge role.

In the past ten years, the numerical control of combined machine tools has developed very rapidly. It should be pointed out that since the 1990s, the competition in the auto market has become more fierce, the market life of the products has been further shortened, the development period of new models has been shortened (at present, it is generally 35 months), and the variety of automobiles has been increasing. Therefore, the auto industry is equipped with flexible automation technologies. The demand is increasing. For example, at the end of this century, the Toyota Motor Corporation of Japan aims to achieve 100% penetration of the flexible processing system of its subsidiary factories. Obviously, under the condition of maintaining high production efficiency, the combined machine tool and its automatic line are more and more important for further improving their flexibility.

China's traditional combined machine tools and combined machine tools mainly adopt machine, electricity, gas, and hydraulic control. Its processing objects are mainly large and medium-sized box and shaft parts with relatively large production volumes. Plates, etc. also occupy a certain share), complete drilling, reaming, reaming, machining various types of threads, borings, car end surfaces and bosses, boring a variety of grooves in the hole, and milling planes and forming surfaces.

The earliest combined machine tools were made in the United States in 1911 to process automotive parts. Initially, each machine tool factory had its own general-purpose component standards. In order to improve the interchangeability of common components of different manufacturers and facilitate user use and maintenance, in 1953, Ford Motor Company of America and General Motors Corporation negotiated with the United States machine tool manufacturers to determine the principle of standardization of common components of combined machine tools, that is, to strictly regulate each The size of the links between parts, but no specification of the part structure.

In China, the development of the combined machine tool has a history of 28 years. Its scientific research and production have a considerable basis, and the application has also penetrated into many industries. It is one of the indispensable equipments for the current machinery manufacturing industry to realize product renewal, carry out technological transformation, and increase production efficiency and rapid development.

The future development of the combined machine tool will adopt more speed control motors and ball screw drives to simplify the structure and shorten the production cycle. The digital control system and spindle box and automatic fixture replacement system will be adopted to improve the process adjustability; and Flexible manufacturing systems. In short, the domestic combination machine tool products will develop toward the direction of flexibility, high speed, and intelligence.
