The grinder is a national 863 support project in 2008.The machine tool adopts the grinding method which is based on the grinding point cut. It does not need the auxiliary mechanism such as eccentric fixture, indexing device and so on. Using imported spindle system, the maximum speed of CBN grinding wheel can reach 120m/s. We have developed the interpolation software of the crankshaft cutting point tracking and grinding, and the grinding point of the grinding wheel is always following the rotation of the crankshaft to realize the high precision grinding of the crankshaft. The feed of the grinding wheel is driven by straight line, which has the characteristics of high acceleration response. At the same time, the rigidity and the sensitivity of the grinding wheel are improved by using the sel...

Hannover European Machine Tool Exhibition: feast not to be missed

Date: 2017-02-16
Browse Number: 18

The world's leading metal processing industry event - Hannover European Machine Tool Exhibition (EMO) after a lapse of 4 years, will be held from September 18th to 23 at the exhibition center in Hannover, germany. According to the German Machine Tool Manufacturers Association (VDW) the relevant person in charge, the exhibition to promote intelligent production system "as the theme, will attract from around the world to show manufacturers production technology of existing solutions, the use of production and operation of digital and network, realize the maximization of the interests of customers, is to use this type of solution. To improve the competitiveness of machine tool suppliers.

At the end of January, exhibitors enterprises has reached more than 1 thousand and 850, from 42 countries and regions, the net exhibition area of over 160 thousand square meters. About 450 exhibitors from Asia, of which nearly 110 from China, the exhibition category includes tools, accessories, metering equipment, machining centers and lathes, etc.. It is reported that this figure is much higher than the previous exhibition.

For the international experts in the metal processing industry, EMO is a feast not to be missed. From the number of viewers, 2013 Hannover European machine tool exhibition attracted from more than and 110 countries and regions of the 143 thousand professional audience, the proportion of overseas audiences more than 42%. The number of overseas visitors have such a high proportion of global production technology exhibition, second to none.

From traditional performance to new features

Hannover European machine tool exhibition will be the world's most concerned about the topic of production technology - digital and networking as an important topic of discussion. In essence, the traditional requirements of machine tools and manufacturing systems are still the top priority. The implementation of quality, productivity, and economic efficiency must be based on mechanical strength, reliable components, reliable mechanical control systems, and intelligent process design and control. Hannover European machine tool exhibition will be fully demonstrated in the field of various types of machinery. Among them, there is no shortage of affordable standard machinery, will also be supplemented with a simple program to modify the program. Strong structure, easy maintenance of standard components, due to the advantages of simple operation, in the price sensitive market demand. According to the company engaged in steel structure, simple machinery manufacturing or multi-purpose machinery production, can be upgraded by three axis machine (if necessary, can increase the axis of fourth), create a new scene. In contrast, the standard concept of components and fixtures can minimize the cost of auxiliary production when purchasing a new machine.

Another major category of the exhibit includes machine tools and die construction machinery. To provide specific support for the manufacture of complex free surfaces, the lengthy part run time can be handled to a large extent without operator involvement. As far as the expensive maintenance tool is concerned, it can be integrated with other technologies of material manufacturing technology. The use of laser or ultrasonic system, the surface of structured processing, so that the professional tactile surface in line with the new needs of consumers.

To meet the requirements of large-scale production and operation of ultra high quality requirements of professional equipment, was included in the exhibition another display category. This kind of equipment and a large number of automation solutions combined with the transformation from simple tray to automatic storage and handling system, integrated use of complete processing and technology, providing maximum reproducibility and availability, to ensure the effective control of cost.

This exhibition will give full play to the current hot topic - the role of big data. For the special application in the production environment, it is necessary to activate the "data grave" to obtain a large amount of measurement data and sensor data from the mechanical state. Specific analysis of a large number of data, to ensure the early detection of the spindle or feed shaft failure, more accurate prediction of maintenance time. The new method of predictive maintenance is based on the algorithm that can be taught, which is far beyond the traditional condition of mechanical monitoring. Continuously monitor all the mechanical status of the manufacturing system and take necessary actions according to the actual data.

The exhibition will also launch a new program to maintain or service work, improve the reality to replace the traditional means of maintenance. With this technology, the software system can detect the mechanical section quickly, and the technicians can locate it quickly. Subsequently, the use of mechanical control system online communication, easy to determine the fault. Can also provide step-by-step guidance, and in accordance with customer needs to carry out product training courses. Even without special training, the staff can take initial measures to remedy the problem.

Intelligent production in potential network

Hannover European machine tool exhibition organizers believe that EMO is an important driving force to promote the development of much of the industry 4 or networking. Sch, the German machine tool manufacturers association, said: "in terms of the machine tool industry, we have already achieved digitization. Digital image simulation techniques have been implemented for quite some time." Currently, the industry's 4 priority is to build a comprehensive production and operation network, and effectively improve the value chain.

Enterprises in the networked manufacturing production line optimization sequence, or flexible production. Thus, even if a small emergency order is received, it can be handled properly. The whole production line, which can carry on the real-time communication and control, will realize the maximization of the value added of the company in the horizontal communication (from the whole process of receiving orders to the delivery of goods). In addition, in addition to the value chain, not only to build a network of suppliers, but also the establishment of logistics partners and the corresponding customer network, in order to achieve productivity, flexibility and efficiency maximization.

To build an effective platform for SMEs

A large number of specific innovation activities, to create additional value for mechanical users, enhance the competitiveness of machinery manufacturers
