Domestic CNC machine tools have begun to mature

The development of the national industrial industry has led to the improvement of machine tool products. At the same time, the promotion of machine tool products is a major boost to the development of the national industrial industry. At present, the machine tool market and CNC machine tools have become mainstream. After more than 30 years of development, domestic CNC machine tools have entered the mature stage, with a wide range of products in a wide range of applications, and breakthroughs in innovation and technology are driving the world's leading level.

Five-axis coordinate linkage CNC machine tool is one of the technical high-level signs of CNC machine tools. Five-axis milling machine for large-scale propeller space curved surface machining has caused a sensational US and Japan sanctions against the former Soviet Union's "Toshiba incident." Eight years ago, the United States Congress imported 16 sets of such multi-axes for aircraft manufacturing. Linking old machine tools to produce the so-called Cox report requiring sanctions.

CNC super-heavy duty machine tools are key equipment for the manufacture of heavy equipment such as water, fire, nuclear power station equipment manufacturing, shipbuilding, metallurgy and mining, and heavy weapons manufacturing. The five vertical CNC lathes with diameters up to 16m have been manufactured by Wuhan Heavy Machine Tool Group and can represent the production capacity and level of super-heavy machine tools in China. The first station had met the urgent needs of users in the manufacture of hydroelectric power generation equipment at Yantan Hydropower Station. In the following eight years, it has repeatedly made great achievements in production and use, and it is referred to by the user as "meritorious equipment." The subsequent stations continued to play an important role for the national key engineering power station equipment, and they were praised by the users for guaranteeing the processing of the 550t giant typhoon runner, which is the world's largest power station. The super-heavy machine tools that have been successfully developed and used include the CNC floor-mounted boring and milling machining center, CNC gantry type, bridge type, and fixed beam type. Compound function knows the milling machine, the processing workpiece weighs 300t. Horizontal lathes with a diameter of 4.5m, workpieces with a weight of 200t and CNC roll grinders with a diameter of 2200mm, only two or three of these machines are produced internationally. China's own copyrighted products have reached the world's advanced level, and China has become one of the few suppliers of super heavy machine tools.

The vertical horizontal machining center integrates the basic functions of the floor milling machine and the bed type milling machine, and has the characteristics of automatic tool change or automatic replacement of the workpiece tray according to the NC program, and also constitutes the basic equipment of the flexible production line, becoming a requirement in the machinery manufacturing industry. A large quantity of processing equipment accounts for about 30% of the total demand for CNC machine tools. It is a hot commodity in the world's machine tool market. China's rapid development in recent years, there are more than 40 companies in production, general-purpose varieties have been mass production, a small number of manufacturers High-precision, large-size products have entered the market.

CNC lathes are also one of the larger proportions among CNC machine tools. China has more than 50 enterprises, and Shenyang Machine Tool Group, Dalian Machine Tool Group, Jinan No. 1 Machine Tool Plant, Baoji Machine Tool Factory, and cloud machines have all batched. Production, the full range, stable and reliable quality, and some have crossed the threshold of 100 sets per month. CNC gear processing machine is also one of the strengths of China's machine tool products, into a series of six-axis five linkage CNC gear hobbing machine, seven-axis five linkage worm gear grinding machine, seven-axis six-motion spiral bevel gear grinding machine, all in the past three years Into the mass production of the world's advanced level of new machine tools.

China's CNC machine tool products have been extended to complete sets and compound fields: Zhongjie Machine Tool Factory has a seven-month delivery schedule for the Shanghai Maglev train project, and it has produced four production lines with CNC boring and milling machines as its main body, which is an embodiment of China's machine tool industry. Excellent representation of equipment capabilities.

The CNC system device is the nerve center of the CNC machine tool and is the key link that has hindered the development of the CNC field in China for a long time. As far as the world is concerned, after years of fierce competition in the market, the survival of the fittest has formed a monopoly by Japan’s Fanuc companies that monopolize the world market by 50% and Germany’s Siemens by 25%. Since the late 1990s, China has mastered the open system architecture based on a general-purpose 32-bit industrial controller and has been able to climb onto the same starting line in the modern era. It has developed a numerical control system that can be matched with a machining center, a compound turning machine tool, and a gear machine tool. Five-axis linkage and CNC system with networked remote monitoring, diagnosis, and operation functions, and the development of spiral bevel gear NC machining.

Three-dimensional laser vision inspection, seven axis five-stroke processing of the propeller and the world's original space surface interpolation software. At present, the domestically-manufactured numerical control systems that have been put into the market in batches have the advantage of price/performance ratio and are changing the monopoly of international elites who can occupy exotic goods in the Chinese market. Matching digital AC servo speed motor and spindle motor have come out with their own copyrighted products.
