1. Machine tool industry overview

 

1.1 Basic introduction of machine tools

 

      Machine tools are those that can complete machining. According to the statistics of China Machine Tool Industry Association, machine tool industry is divided into metal cutting machine (car, milling, planing, grinding machine, etc.), forming machine tools (forging, casting, stamping equipment), tools and accessories, Only refers to the metal cutting machine.

 

      Machine tools can be divided into lathe, milling machine, planer, grinder, boring machine, drilling machine, etc .; some with two functions of the machine, such as boring and milling machine. According to the machine position, divided into vertical, horizontal, gantry and so on.

 

      CNC machine tools are developed in the ordinary machine tool is to install the CNC machine tools. CNC machine tools are electronic information technology and traditional mechanical processing technology combined with the product, is the mainstream of contemporary machinery manufacturing equipment. Processing center is able to complete a variety of mechanical processing functions of the machine equipment, including milling, boring, drilling and so on.

 

      The machining center is a high level of CNC machine tools.

 

       1.2 basic characteristics of the machine tool industry

 

      1.2.1 The machine tool industry is a national strategic industry

 

      The machine tool is the equipment of the equipment manufacturing industry, is to the traditional machinery industry, automobile industry, power equipment, railway locomotives, ships, defense industry, aerospace industry, electronic information technology industry and other processing industry to provide processing equipment sector. Revitalize the equipment manufacturing industry, first of all to revitalize the machine tool industry.

 

      The development level of the machine tool industry in a country is already an important index to measure the current level of manufacturing and industrial modernization. It is also an important index to measure the comprehensive competitiveness of the country. Especially for the defense industry, the machine requirements are high, complex, high-precision parts processing (such as aircraft engine blades, missile tail nozzle, etc.) non-multi-axis linkage, high-speed high-precision CNC machine tools can not be processed. Therefore, the machine tool industry is a national strategic industry.

 

      1.2.2 CNC machine tools are technology-intensive products

 

The CNC machine tool is composed of main engine, numerical control device, driving device, auxiliary device and programming and other ancillary equipment. It integrates the new technological achievements in many fields such as modern precision machinery, computer, automation, servo drive, hydraulic pneumatic, precision measurement and photoelectric, Technical content is high, are technology-intensive products.

 

      2. General analysis of machine tool industry

 

      2.1 Machine tool industry cyclical analysis

 

      From the industry life cycle, the general machine tool industry into the mature period. The output of the machine tool industry and the growth of fixed assets investment in the downstream are kept at a synchronous trend, showing a clear periodicity.

 

      For CNC machine tools, after experiencing the naive period of the 1990s, into the high-speed growth period. Compared with the United States, Germany and Japan, CNC machine control rate is still very low, the trend of rapid growth will continue.

 

      2.2 machine industry growth analysis

 

      In the past five years, the machine tool industry has maintained an average growth rate of 28%. Since the second half of 2004, affected by macro-control policies, the pace of development of the industry has slowed down. 2006 is the "Eleventh Five-Year Plan" the first year, the industry continued to expand the scale of production, from January to June 2006 industrial output value increased by 29.41%, sales revenue grew 30.52%, growth continues to maintain high.
