Looking back on the past 2014, it continues to be a bit dull in the low-end machine tool industry, but carefully combed, China Industry News reporter found that there are still many bright spots, it seems to show the society: machine tools, this traditional mechanical products, not the sunset industry. On the contrary, after a period of accumulation, it is possible to create a more dazzling performance than the "Golden Decade." Data is not optimistic
Although comprehensive industry statistics have not yet been exposed, it is not difficult to conclude from the comprehensive mid-year statistics and public information of listed companies: In 2014, the economic operation of the machine tool industry generally showed “low-level stabilityâ€.
Although the government has increased its policy of stabilizing growth and responding to economic downturn since the second quarter, there have been multiple adjustments in domestic market demand, slow recovery of international market demand, increased competition for imported goods, severe lack of liquidity, and long-term deterioration of financial conditions. Under the combined influence of unfavorable factors, business difficulties and potential risks have intensified, and the operating pressure of the industry is still very large.
An indisputable fact is that at present, the profit margin of the main business of the industry is generally lower than the one-year deposit rate of the bank. In other words, from the perspective of profitability, it is better to deposit money with the bank than to invest in production. According to the semi-annual data released by the National Bureau of Statistics, the metal cutting machine tool industry has the most serious losses, with nearly one-quarter of the losses. The loss of its Chinese enterprises is even more shocking, reaching more than half. The gold cutting machine is the most mainstream product in the machine tool industry.
From the microscopic point of view, many small workshop-style machine tool manufacturers have gradually closed down, and small exhibitions have been cancelled due to unsatisfactory exhibitions. The above judgments have also been confirmed from the side.
Of course, the survival of the fittest is not necessarily a good thing, and the industry will usher in a new life in integration. The reporter searched the public information of the two listed companies of Shenyang Machine Tool and Qinchuan Development. According to the data, as of September 30, 2014, Shenyang Machine Tool achieved a net profit of 16.85 million yuan, a year-on-year increase of 41%. Years are negative. Coincidentally, Qinchuan's machine tool products achieved a gross profit of 26% in the first half of the year, an increase of 10% from the previous year.
The parent companies of Shenyang Machine Tool and Qinchuan Development are Shenyang Machine Tool Group and Qinchuan Group respectively, which are ranked among the top three in China's machine tool industry according to their scale. It can be seen that the Matthew effect of the strong Hengqiang began to appear.
Experts from China Machine Tool & Tool Industry Association judged that due to the slowdown of China's economic growth and the change of development mode, China's machine tool consumer market and industry are also experiencing profound structural adjustments, characterized by “significant reduction in total volume and accelerated structural upgradingâ€. Market changes are increasingly evident. As China's economic development enters a new normal, demand changes in the machine tool consumer market will also stabilize.
At present, the industry's view on the future trend is generally that the industry market has bottomed out and will not have a big decline, but when it can get out of the trough, it still needs to look at the macroeconomic trend.
From the analysis of the mainstream user groups in the machine tool industry, only the growth of the automotive industry is relatively stable, and other projects such as construction machinery and ships have been in recession in recent years.
Innovation does not stop
When you are busy, you should cope with the market. This has become a normal state of the industry, so in a relatively low market environment, technological innovation is still in full swing.
On January 14, 2014, the “CNC Heavy Duty Crank Milling and Multi-tasking Machine Tool†project undertaken by Qizhong CNC Equipment Co., Ltd. passed the acceptance test at Qingdao Haixi Heavy Industry Co., Ltd. (user site) in Qingdao, Shandong Province.

In October, the crankshaft grinding equipment developed by Beijing No. 2 Machine Tool Plant (Beiji Machine Tool) won the special award of the National Machinery Industry Science and Technology Award in 2014. The crankshaft is a key component of a piston-type internal combustion engine, and the rotation of the crankshaft is the power source for the entire mechanical system. The above results mean that China has become the fourth country to follow the grinding technology and equipment after the British, German and Japanese. The North Second Machine Tool has become the only internationally capable complete machining equipment for crankshaft grinding and polishing. Machine tool manufacturer.
Also in October, the world's largest processing diameter seven-axis six-coupling propeller processing machine independently developed by Nanjing High-precision Transmission Equipment Manufacturing Group Co., Ltd., a subsidiary of Nanjing High-Precision Transmission Equipment Manufacturing Co., Ltd., was used by Wuhan Heavy Industry Casting & Forging Co., Ltd. On-site assembly is completed and performance indicators meet and exceed user expectations. This kind of machine tool is used to process some kinds of propeller parts with complex shapes and high precision in aerospace and shipbuilding industry. In the future, large-scale military and civil ship propellers in China may be processed by this machine tool.
After eight years of research and development, the team led by Prof. Zhao Wansheng from the School of Mechanical and Power Engineering of Shanghai Jiaotong University broke through a series of key technologies in 2014 and successfully developed the “six-axis linkage CNC EDM machine tool†and developed the supporting CAD. The /CAM software and processing technology provide a comprehensive technical solution for the manufacture of closed integral turbine blades for rocket engines. The technology was unveiled at the China International Industry Fair in November.
According to statistics, about 45% of the cases of rocket launch failures at home and abroad are caused by the failure of turbine blade parts used by rocket engines. This kind of part is the core key component of aerospace and aerospace engines, which largely determines the reliability, performance and cost of the engine. However, in the past, such parts were generally purchased by import in China.
In December, the high-end heavy-duty 2500kN multi-station automatic stamping production line jointly developed by China General Technology Group Qiqihar Second Machine Tool (Group) Co., Ltd. and Hagel Company of Germany was successfully developed and officially established in Guangdong Fudi Automobile Co., Ltd. The 800-ton blanking automatic production line is also put into use, and the 3200kN multi-station automatic stamping production line is being commissioned.
This 25,000kN press line installed in Guangdong Fudi Automobile Co., compared with the same tonnage multi-station press, has a larger work surface, a wider stamping range and more complete functions. It integrates modern CNC, communication, sensing and hydraulic pressure. With high-end technology such as pneumatics.
Due to the complexity of design, the difficulty of manufacturing, and the high cost, this type of multi-station press has only a few German and Japanese professional manufacturers of presses in the early stage. The large domestic auto companies are all importing large prices. At present, Qi Er Machine Tool has the ability to provide such products. It is of great significance to break the foreign monopoly, promote the sustainable development of the domestic automobile manufacturing industry, and improve the overall technical level of domestic multi-station press products.
Accelerated capital operation
In the downturn of the international machine tool market, the two Zhejiang enterprises made overseas acquisitions and earned their eyeballs in 2014.
On May 7th, Nissin Seiki acquired Italian MCM Company and began to fully deploy the aerospace market based on its advantages in the processing of high-temperature alloy materials such as aluminum and titanium.
Taizhou Beiping Machine Tool Co., Ltd., located in Wenling, signed an acquisition agreement with German Shiron Pressure Machine Co., Ltd. Beiping Machine Tool invested 3 million euros and acquired the nearly 100-year-old machine tool company in Germany, completing the first overseas acquisition of local machine tool companies.
Good things are in pairs. In November, two other companies in the machine tool industry were successfully listed. The A shares of Hefei Forging Machine Co., Ltd. were listed on the Shanghai Stock Exchange on November 7, 2014, and the initial public offering of shares was 45 million shares. On November 11, Ningbo Jingda Forming Equipment Co., Ltd. was listed on the Shanghai Stock Exchange. The company's initial public offering of shares did not exceed 20 million shares.
The shares of the two companies are sought after in the secondary market, and the joint forging shares even created a "stock stock myth" of 19 consecutive daily limit.
Capital operation is not limited to the industry, the famous Foxconn joined the battle group of machine tool wars in 2014. On November 12, Foxconn acquired an 80% stake in Hongqing Precision Machinery Co., Ltd., which is known for producing CNC machine tools and precision machinery, in Anqing. Some analysts said that this indicates that Foxconn is shifting from manufacturing to smart manufacturing, and Anhui has become Foxconn's strategic transformation started.

It is a high-tech company specializing in the production of CNC machine tools, precision machinery and its automation systems. Hefu Technology is a subsidiary of Foxconn. Founded in September 2007, the company is headquartered in Taichung, Taiwan. Currently, it has many branches in mainland China. Among them, the larger operating centers are Shenzhen, Zhengzhou and Chengdu. 350 items. The company's development products such as CNC numerical control systems and servo drive systems have strong market competitiveness.
According to relevant analysis, Foxconn will expand its production of robotic servo systems and automation of key components in Anqing, which indicates that Foxconn is transforming from manufacturing to smart manufacturing.
Sintered NdFeB magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.
As of 2012, 50,000 tons of neodymium magnets are produced officially each year in China, and 80,000 tons in a "company-by-company" build-up done in 2013. China produces more than 95% of rare earth elements, and produces about 76% of the world's total rare-earth magnets.
Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C).
Sintered Nd2Fe14B tends to be vulnerable to corrosion, especially along grain boundaries of a sintered magnet. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spallingof a surface layer.
This vulnerability is addressed in many commercial products by adding a protective coating to prevent exposure to the atmosphere. Nickel plating or two-layered copper-nickel plating are the standard methods, although plating with other metals, or polymer and lacquer protective coatings are also in use.
Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:
ï‚·Head actuators for computer hard disks
ï‚·Magnetic resonance imaging (MRI)
ï‚·Mechanical e-cigarette firing switches
ï‚·Locks for doors
ï‚·Loudspeakers and headphones
ï‚·Magnetic bearings and couplings
ï‚·Electric motors:
ï‚·Cordless tools
ï‚·Servomotors
ï‚·Lifting and compressor motors
ï‚·Synchronous motors
ï‚·Spindle and stepper motors
ï‚·Electrical power steering
ï‚·Drive motors for hybrid and electric vehicles. The electric motors of each Toyota Prius require 1 kilogram (2.2 pounds) of neodymium.
ï‚·Actuators
ï‚·Electric generators for wind turbines (only those with permanent magnet excitation)
ï‚·Direct-drive wind turbines require c. 600 kg of PM material per megawatt
ï‚·Turbines using gears require less PM material per megawatt
