"Since the financial crisis, machine tool enterprises have faced two major challenges. First, due to the direct impact of the international financial crisis, the domestic and international markets have shrunk, exports have declined sharply, production and sales have declined, stocks have increased sharply, funds have been scarce, and competition has intensified. This is an unconventional challenge faced by enterprises; the second is that the world's scientific and technological progress and the needs of users are changing rapidly. The contradictions accumulated by the rapid development of enterprises for many years are erupting in an instant, and it is difficult to cope with them at the moment, which is seriously unsuitable. This is the ability to adapt to business operations. And the double challenge of speed." On July 7, Wu Bolin, executive vice president of China Machine Tool Industry Association, told China Industry News.
Under the impact of the financial crisis, enterprises must face two challenges at the same time and bear tremendous pressure. The research team of the association found that the degree of impact and speed of change in the financial crisis is very different due to the difference in product structure and resilience of the enterprise.
Flow-type products are unable to return to the sky
Wu Bolin said that since the financial crisis, China's machine tool market demand has undergone major changes.
From the perspective of quantity, the market size has generally shrunk. According to relevant enterprises, the financial crisis has affected the market size by more than 20%.
From the qualitative point of view, the market demand structure has changed significantly, the demand for ordinary and low-grade machine tools has shrunk dramatically, and large, heavy and high-end CNC machine tools still maintain stable demand. The demand for machine tools in various industries of the national economy has been uneven. Some industries, such as railway, aviation, and energy, have basically not affected the demand for machine tools. The demand for machine tools in automobile manufacturing has begun to rise.
According to the conventional statistics of the 177 key contact enterprises of the Machine Tool Association, the numerical control rate of metal processing machine tool output value was 53.9% from January to May 2009, an increase of 7.6 percentage points year-on-year; among them, the output of gold cutting machine tools decreased by 38.4%, CNC cutting machine Production fell by 23.9%, but the output value of CNC metal cutting machine tools increased by 9.4% year-on-year.
The demand for ordinary machine tools has dropped drastically, although the number of CNC machine tools has declined, but the demand for large and high-end CNC machine tools is relatively strong. The decline of traffic-type products seems to be a foregone conclusion.
According to the major manufacturers in the industry, ordinary lathes, ordinary drilling machines and ordinary milling machines have reduced production by more than 30%, the production ratio of small and medium-sized general-purpose grinding machines has decreased by 40%, and the production of low-grade EDM wire-cutting machines has decreased by 50%. The output ratio of large-scale CNC machine tools has steadily increased.
Imported products impact the domestic market
“The Russian government has also recently launched a special machine tool with a total investment of US$500 million. The machine tool companies in the country have placed their hopes of recovery on the Chinese market.†Wu Bolin, who just finished his visit to Eastern Europe, told the China Industry News reporter.
Foreign companies are optimistic about the Chinese market, and they have aggressively attacked the cities in China, which has intensified the fierce competition in the industry.
In the middle and low-end CNC machine tools and tools, due to the shrinking market and overcapacity, coupled with the low price of products from South Korea and Taiwan, the competition of domestic enterprises will further intensify.
And high-end products are also facing strong challenges from foreign companies. Due to the financial crisis, the international economy is in a downturn. Powerful multinational companies are eyeing China's huge machine tool market and adopt various means to enter the Chinese market.
The impact of the import of high-performance functional components and CNC tool products on China's corresponding enterprises will be very serious. From January 2008 to May 2009, China's imports of metal processing machine tools reached 10.08 billion US dollars, accounting for 39% of the domestic market. The import of metal processing machine tools continues to operate at a high level, which has created great market pressure on domestic machine tool manufacturers.
Industry operation is in a downward trend
According to the regular statistics of the association's 177 key enterprises, the total industrial output value decreased by 5% from January to May in 2009, the sales revenue decreased by 6.2% year-on-year, and the total profit decreased by 33.1%. Statistics show that since 2009, the economic operation of China's machine tool industry has continued its downward trend in the fourth quarter of last year. The market has shrunk, exports have been blocked, and funds have been tight. The total industrial output value and sales revenue showed a year-on-year decline, and the total profit fell by a large margin.
According to the statistics of 114 companies (including major enterprises in the whole industry) on the spot, the total output value of the whole industry decreased by 6.3% from January to April 2009, the sales revenue decreased by 11.9%, and the total profit decreased by 45.9%. Among them, the number of enterprises whose output value decreased year-on-year accounted for 70.2% of the total number of research enterprises (50% of the enterprises with a decline of more than 20%); the number of enterprises whose sales revenue decreased year-on-year accounted for 71.1% of the total number of research enterprises (a company with a decline of more than 20%) The number accounted for 48.3%); the number of enterprises whose total profit decreased year-on-year accounted for 71.1% of the total number of enterprises surveyed (the number of enterprises with negative profit total accounted for 25.4%).
Wu Bolin believes that the above data is in good agreement with the regular statistics of the key enterprises of the association, indicating that due to the financial crisis, the economic operation of the machine tool industry continued to decline. The business operation began to polarize, and about 70% of the enterprise economic indicators were in a downward channel. One quarter of the companies are at a loss.
The impact of the crisis on the company is different.
Wu Bolin told the China Industry News reporter that from the overall situation of the survey, the impact of the financial crisis on machine tool enterprises can be roughly divided into three categories.
The first type of enterprises have a small degree of influence and the business operations are in good condition. The main performance is as follows: the product structure basically adapts to the market demand, the manufacturing task is relatively full, the output value and sales revenue increase year by year, and the total profit maintains a good level. These companies account for about 30% of the total number of companies surveyed.
From the research enterprise analysis: Most of the key enterprises with large, heavy, high-grade and special CNC machine tools as the leading products, due to the high technical content of the products, in line with the current market demand, the order contract is full, the output value and sales revenue have a large increase, the profit The total amount is at a good level. These typical enterprises are: Jinan Second Machine Tool Group Corporation, Wuhan Heavy Machine Tool Group Corporation, Qizhong CNC Equipment Co., Ltd., Qi Er Machine Tool Group Co., Ltd., Qinghai Huading Heavy Machine Tool Co., Ltd., Beijing No. 1 Machine Tool Plant, Ningbo Haitian Seiko Machinery Co., Ltd., Tianshui Forging Machine Co., Ltd., Yichang Changji Technology Co., Ltd., Taian Hualu Forging Machine Co., Ltd., etc.
For example, Jinan No. 2 Machine Tool Group achieved a total output value of 530 million yuan in the first four months of this year, an increase of 27.3%; sales income of 510 million yuan, an increase of 24.3%; total profit of 21.86 million yuan, an increase of 167.6%; existing orders 7.6 100 million yuan.
In another example, Wuhan Heavy Machine Tool Group Corporation achieved a total output value of 362 million yuan in the first four months of this year, a year-on-year increase of 29.8%; sales revenue of 391 million yuan, an increase of 25.8%; total profit of 35.65 million yuan; existing orders of 3.2 billion yuan; 255.5 million yuan, an increase of 5.5%.
In addition, Qinghai Huading Heavy Duty Machine Tool Co., Ltd. completed a total output value of 126 million yuan in the first four months of this year, an increase of 27% over the same period of last year, of which 63 tons of machine tools and CNC machine tools increased to 71.5%; total profit of 5.55 million yuan, an increase of 105.2 %; in the hand orders 700 million.
At the same time, a group of new technology companies with universities, research institutes and backgrounds are operating well. A group of private and private enterprises with strength in the machine tool industry have a busy production task. Under the influence of the global financial crisis, they have shown a strong momentum of development.
The second category of enterprises have experienced a general decline in economic indicators since 2009, with a decline of between 10% and 30%, which is greatly affected by the financial crisis. However, due to the timely and active adjustment of the company, the effect is relatively obvious, and the operating status can still be maintained.
This type of enterprise not only produces medium and low-grade batch products, but also partially produces high-end CNC machine tools and special machine tools. The influence of enterprises in the financial crisis mainly determines which products in their leading products account for a large proportion, depending on the ability of enterprises to adjust their existing product structure to quickly adapt to the market. High-end CNC machine tools and special machine tools still maintained rapid growth when such enterprises experienced a significant decline in the production and sales of medium and low-end batch products. Due to the high quality of products, reputation and brand influence of these enterprises, they have certain competitiveness. The high-end CNC machine tools produced by them are the urgently needed products of the national development equipment manufacturing industry, which can replace some imports, so they still have recovery and development. potential.
Such companies accounted for the largest proportion of the survey, accounting for about 60% of the companies surveyed. In addition to the above-mentioned first-class enterprises, most of the enterprises in China's machine tool industry belong to the second category.
The third-class enterprises have experienced a significant decline in sales revenue since 2009, which is seriously affected by the financial crisis. The total profit of the enterprises has a large negative value, and the operating conditions are very difficult.
The main reasons for the difficulties in operation are: the enterprises mainly produce low-grade and ordinary products, the products are backward, the technology added value is low, the market shrinks, and the business operation is difficult to sustain; but some enterprises are restricted by the management system, the enterprises are burdened, and the productivity is difficult to play. Some enterprises have formed a capital chain imbalance due to mistakes in major investment decisions.
The third category of enterprises accounted for about 10% of the total number of research enterprises. Such enterprises are in a passive adjustment situation in the midst of the financial crisis.
In addition, the research team also learned about some foreign-funded and Taiwan-funded enterprises. The overall situation is that these enterprises have been affected by the financial crisis to varying degrees. Most of the enterprises' sales have dropped by about 20%, and individual enterprises have remained flat or slightly increased.
Under the impact of the financial crisis, enterprises must face two challenges at the same time and bear tremendous pressure. The research team of the association found that the degree of impact and speed of change in the financial crisis is very different due to the difference in product structure and resilience of the enterprise.

There are raceways on the inner and outer rings of angular contact ball bearings, and the inner and outer rings can be displaced relative along the axial direction of the bearing. These bearings are particularly suitable for combined loads, i.e. loads that act in both the radial and axial directions. The axial load bearing capacity of angular contact ball bearings increases with the increase of contact angle α. The contact angle is the angle between the contact point connection between the ball and the raceway in the radial plane and the perpendicular line of the bearing axis.
The types of angular contact ball bearings are divided into: α=15° angular contact ball bearings (70000C type); α=25° angular contact ball bearings (70000AC type); α=40° angular contact ball bearings (70000B type); Back-to-back paired double angular contact ball bearings [70000C(AC, B)/DB type]; Face-to-face paired double angle contact ball bearings [70000C(AC, B)/DF type]; Tandem Paired Double Angular Contact Ball Bearings [70000C (AC, B)/DT Type]; Double row angular contact ball bearings with ball notch (00000 type); Double row angular contact ball bearings without ball notch (type 00000A); Double row angular contact ball bearing without ball notch, one side with dust cap (00000A-Z type); Double row angular contact ball bearings without ball notch, with dust caps on both sides (00000A-2Z type); Double row angular contact ball bearing with sealing ring on one side without ball notching (00000ARS type); Double row angular contact ball bearings with sealing rings on both sides without ball notching (00000A-2RS type); Four-point angular contact ball bearings (QJ0000 type), a total of 13 types
