Han Zhong Machine Tool Chief Zhao Zhongqi proposed the development strategy of the grinding machine industry

In an interview with the metal processing online reporter, the chief engineer of Hanjiang Machine Tool, Zhao Zhongqi, said: The grinding machine enterprises should develop rapidly, and the product technology must make breakthroughs and reach the international advanced level before they can be competitive. To this end, the following development countermeasures and suggestions are proposed.

1. Adhere to the development direction of independent innovation technology and strengthen system integration. The innovative CNC machine tool consists of functional components, numerical control system, basic components and various special components. Each link must ensure advanced technology, stable quality and reliable performance. Because of this, the state has arranged the functional components and numerical control system as the top priority of the breakthrough of CNC machine tools in the “04 Special Project”. It is believed that through the efforts of relevant enterprises and colleges, the technical level of functional components and CNC systems will be As we embark on a new level, reliability has been further improved. However, how to seamlessly connect various functional components with advanced technology and integrate them into high-end CNC machine tools is a common problem faced by the machine tool industry. Therefore, it is recommended that:

(1) Carry out research on the theory and method of grinding machine design to meet the needs of high-end CNC machine tool design. The advanced design concept is condensed with the exquisite manufacturing process. This is the Smart technology, which is the way to ensure that the machine achieves its best performance. The modern technologies for realizing these methods are: 1 digital virtual prototype design technology, its functions and functions are component design, virtual assembly and motion simulation, which can reduce costs. 2 finite element analysis technology, its function and role are thermal deformation stability, dynamic characteristics analysis, and propose optimization schemes and measures. 3 structural optimization design technology, its function and role is to optimize the product structure based on analysis or experimental verification.

(2) Emphasis on industrial design technology, strengthen the cultivation of professional talents, and develop pleasant products. The introduction of industrial design technology into China's machine tool industry has also been in the past 20 years, and its role has been obvious to all, basically changing people's impression of domestic machine tools "stupid and stupid". At the same time as the products of the industry are “new and new”, we also see that the product design level of each enterprise is uneven, and the manufacturing process is still rough. Compared with the international advanced level, the gap is obvious. Lack of it. The good news is that more and more colleges and universities have set up industrial design majors, which laid the foundation for the source of talent in the industry.

Machine tool enterprises should also change the traditional concept that “the wine is not afraid of the deep alley”. In addition to the effective performance and reliability of the machine tool, it also needs the design of the machine tool (mainly including ergonomics, color science and machine tool functions). Need to wait) to work hard to increase the selling point of CNC machine tools.

(3) Master the core technology of high-grade grinding machine design and provide users with comprehensive solutions. Grinding as a terminal process for the processing of product parts is an important means to ensure the accuracy of parts. Therefore, the stability and reliability of the grinding machine have higher requirements than other types of machine tools. To research and develop high-grade CNC grinding machines, we must master its core technology and combine the user's process requirements to provide users with comprehensive solutions.

These key common technologies mainly include: 1 Open CNC system with independent intellectual property rights and suitable for high-grade CNC grinding machines. 2 high-grade CNC grinding machine dynamic error compensation and heat balance technology. 3 Application software for various process requirements, establish a grinding process database.

The technological development direction of independent innovation is the direction that our metal processing industry must adhere to, and it is also the direction of metal processing online as the key media coverage of the industry.

2. Strengthen technological innovation and increase technological transformation

(1) Formulate preferential policies, create a high-skilled personnel training environment, and improve the skill level of employees. The machine tool industry is a highly technical and labor intensive industry, and grinding machines are the pride of machine tools. So far, in the manufacturing process, many key processes are still not guaranteed by the current equipment, and must be completed by skilled craftsmen. Therefore, talents are particularly important, but the reality is that machine tool enterprises generally have high-skilled talent shortages. In addition to attaching importance to the development of talent training, it is also necessary to pay attention to the cultivation and use of highly skilled personnel.

(2) Innovative process design to achieve standardization of the process. The breakthrough of process technology is an important guarantee for the improvement of precision, performance and reliability of CNC machine tools. It is a powerful measure to achieve efficient operation of production process, improve processing level and reduce cost. Because of this, more and more manufacturers attach great importance to process innovation as the driving force of enterprise development, and list a number of key issues to focus on.

In recent years, our company has clearly defined key research projects in combination with its own mainstream products: 1 new process research, new material application technology (complex line grinding wheel dressing technology, high efficiency tool test, high rigidity internal threaded rod material and processing technology, etc.). 2 high-speed and efficient green processing manufacturing technology (high-efficiency grinding of thread, cutting fluid injection technology, cutting fluid filtration and oil mist treatment). 3 precision machining consistency control technology (standardized personnel operation, mechanical equipment, material heat treatment, processing methods, working environment and standardization of process, process inspection and other processes).

(3) Strengthen the construction of innovation platforms and improve the means and capabilities of technological innovation. "If you want to do something good, you must first sharpen your tools." Machine tool enterprises first intensified technological transformation in processing and manufacturing equipment, test instruments and testing instruments, rationally planned, adjusted and transformed production processes, adopted advanced manufacturing processes, and promoted standardized and modular manufacturing technologies; secondly, added CNC machining equipment. , strengthen process control, pay attention to details, civilized production, ensure CPK value, thereby improving work efficiency and achieving large-scale production of high-grade CNC grinding machines. Otherwise, the equipment capacity is not strong, how to produce high-performance CNC machine tools.

3. Machine performance stability and operational reliability issues need to be solved in order to improve product reliability and enhance market competitiveness . In terms of reliability system research, here are some plans for Hanjiang Machine Tool Co., Ltd. on the construction of high-end CNC machine tool reliability system, and I hope to help everyone.

Based on the product structure of Hanjiang Machine Tool Co., Ltd. and the current status of reliability research, the “Reliability Management System” construction project plans the following ten aspects:

(1) Establish a reliability review system.

(2) Establish a product life cycle checklist system.

(3) Establish fault tree (FTA) and failure mode analysis (FMEA) for typical machine tools.

(4) Establish a mathematical model of the typical machine tool failure rate curve.

(5) Establish a reliability and performance test platform.

(6) Study early fault elimination techniques.

(7) Establish a reliability design analysis platform.

(8) Research and development of consistency control technology for parts processing.

(9) Research and development of assembly-oriented reliability control technology.

(10) Research and development of user use conditions and environmental control technologies.

Through the above ten systematic research, the chief engineer of Hanjiang Machine Tool Zhao Zhongqi hopes to standardize the reliability management process of the company's products, and the management technology can make a breakthrough. The MTBF can approach or reach the international advanced level and truly integrate with the world, thus improving The international competitiveness of our products creates our own international brands. Metal processing online hopes that more grinding companies will produce more competitive grinding products.
