——Entering Zhejiang Yuhuan Machine Tool Industry In 2010, China's machine tool industry showed a blowout-type development. The latest data showed that from January to October, the output of CNC machine tools was 179,900 units, which exceeded the level of 145,400 units in 2009. What are the reasons for the rapid development of the Chinese machine tool industry? What is the real situation? To this end, the reporter and his party inspected the production base of economical CNC machine tools and representatives of the private machine tool industry—Zhejiang Yuhuan Machine Tool Industry.
Key words: The exhibition is booming From October 29 to 31, 2010, the 7th China (Yuhuan) Tool & Die Exhibition was held in Zhejiang Yuhuan Exhibition Center. There was no special exhibition hall, but it was built on the open space in front of the exhibition center. There were 7 greenhouses, but the booth area had reached 15 000m2, 600 standard booths, which was unique in a county-level machine tool exhibition.
Yuhuan County is an island county, but Yuhuan people do not make a living by fishing. On the contrary, the county has more than 10,000 large and small enterprises, and gradually formed automobile and motorcycle fittings, valve plumbing and other industrial clusters. In recent years, these industries have driven the development of the local machine tool industry. There are more than 200 existing machine tool companies and more than 70 machine tool manufacturers. In 2010, the production of machine tools was estimated to reach 30 000 units, of which about 30% were used by Yuhuan Business purchases.
At the exhibition site, Lin Zongxin, general manager of Zhongxing Numerical Control Co., Ltd., and the reporter were interrupted by the on-site customer and customer calls. The company established in 1985 has now formed CK series CNC lathes and CJ series instrument lathes. Hundreds of varieties, annual production capacity of more than 20,000 Taiwan.
Why is the machine tool industry so hot? Zhao Xuyang, general manager of Jinding CNC Machine Tool Co., Ltd. analyzed that: First, the purchase of the machine tool was compressed due to the financial crisis, and it was suddenly released after the crisis. Second, labor shortages occurred everywhere, resulting in a substantial increase in the demand for CNC machine tools, because a worker can operate Multiple CNC machine tools.
Key words two: Pulling the limit of the motor bed The hot market of the tool industry could have made these private enterprises earn a lot of money. However, unfortunately, on this juncture, the coastal industrially developed areas have begun to continuously limit their use. Electricity. In order to meet the central government's "Eleventh Five-Year Plan" energy-saving targets, all localities began to save electricity in the short term, and many companies were forced to "stop four times and open three" within a week. The company started a serious shortage and its production capacity dropped drastically. In fact, the machine tool industry is a low-energy-consumption enterprise. The various types of CNC machine tools it produces are among the low-energy-consuming equipment necessary to promote the upgrade of manufacturing equipment and achieve energy-saving and emission-reduction. However, the power sector does not distinguish the production nature of enterprises. The implementation of non-discriminatory power cuts, in a sense, has delayed the smooth implementation of energy-saving emission reduction targets.
Zhang Huijian, director of the Kanmen Machine Tool Plant and president of the Yuhuan Machine Tool Industry Association, said: “The biggest impact of power cuts on the machine tool industry is that the industrial supply chain is seriously unsmooth. Our upstream companies such as functional parts and auxiliary processing companies The production capacity of the Yuhuan machine tool industry was expected to double in 2010, but now it can reach 2009. The annual growth rate is good."
Keywords 3: Attracting talent Zhang Huijian said that Yuhuan's front-line industrial workers have a large gap. The machine tool industry is different from other industries, in particular, it requires very skilled technical workers, it is impossible to buy equipment today, and it can be produced tomorrow. It takes at least one year for input and output of human resources. This is also one of the factors restricting Yuhuan Machine Tool's expansion of production capacity.
The bigger problem is that many young people are reluctant to go to the workshop as workers. Zhang Huixiang, secretary general of the Yuhuan Machine Tool Industry Association, said that Yuhuan lacks about 8,000 technical staff. The local economic and trade bureau once went to Sichuan to recruit laborers, but it still cannot solve all the problems, and there are even more shortages of skilled personnel, especially skilled assemblers. In order to attract and retain talented people, Yuhuan's companies have made considerable efforts in corporate management, corporate culture, and employee benefits.
Jin Yihong, general manager of Taizhou Zhenhuan CNC Machine Tool Co., Ltd., told the reporter that the company has long provided internships for students of schools like Jiangnan University of Technology, selected some reserve talents from internships, and long-term cooperation with Wuhan University of Technology, Zhejiang University and other schools, through School, school professors, doctoral students, graduate students to the company technical guidance and other forms to improve machine tool design and manufacturing technology.
When the reporter visited Zhejiang Heideman Machine Tool Manufacturing Co., Ltd., he was laughed at by two jokes in the company's toilet. Chairman Gao Changquan told us that the management slogans and slogans in the company are all proposed by the employees. Once adopted, the company will reward the employees. The company pastes the employee's daily barometer on the shop floor, and provides psychological guidance according to the different moods such as “sunny dayâ€, “cloudy day†and “raining†in the table; firstly giving the employee a “couple room†free of charge and solving the housing problem of the employees. . In particular, Gao Dong was touched by the fact that at the moment of the financial crisis, all middle-level leaders actively applied for a pay cut to tide over the difficulties. Gao Dong sensationally said: "Corporate culture is the culture of the boss. The boss's usual manners and the feelings of the employees and the employees must be proved by practical actions. Our staff is very stable because of deep feelings."
Keyword 4: zero-degree innovation Zero-degree innovation is an innovative method that can be produced in a free state and that can be created independently and independently, and that can also use various external essences for my own use. This innovative method is most suitable for private enterprises nowadays. At present, private enterprises have begun to change from innovation to independent innovation.
Zhang Huijian said that in order to meet the energy saving requirements of enterprises, Kanmen Machine Tool invested RMB 16 million in 2010 and Southwest University jointly developed an automatic transmission mechanism for machine tools. This mechanism can automatically shift gears according to the cutting resistance and automatically change the output torque. At present, it is entering the identification stage. This set of institutions can save energy by 20% and can save more than 50% on large machine tools.

Hobbing uses a hobbing machine with two skew spindles, one mounted with a blank workpiece and the other with the hob. The angle between the hob's spindle (axis) and the workpiece's spindle varies, depending on the type of product being produced. For example, if a spur gear is being produced, then the hob is angled equal to the lead angle of the hob; if a helical gear is being produced then the angle must be increased by the same amount as the helix angle of the helical gear. The hobbing features for gears are straight, helical, straight bevel, face, crowned, worm, cylkro and chamfering. The two shafts are rotated at a proportional ratio, which determines the number of teeth on the blank; for example, for a single-threaded hob if the gear ratio is 40:1 the hob rotates 40 times to each turn of the blank, which produces 40 teeth in the blank. If the hob has multiple threads the speed ratio must be multiplied by the number of threads on the hob. The hob is then fed up into the workpiece until the correct tooth depth is obtained. Finally the hob is fed through the workpiece parallel to the blank's axis of rotation.
Often, during mass production multiple blanks are stacked using a suitable fixture, then cut in one operation.
For very large gears the blank can be gashed to the rough shape first to make hobbing easier.
