The first national standard in the field of machine tool remanufacturing has been approved

The first national standard in the field of machine tool remanufacturing, "Guidelines for the Remanufacturing of Green Manufacturing Metal Cutting Machine Tools," has been approved. The first heavy heavy-duty machine tool remanufacturing standard is being drafted. This is the information the reporter received from the recently held "2012 Machine Tool Remanufacturing Standards and Technology Seminar".

The market urgently requires that remanufacturing is the advanced stage of machine tool repair and transformation, and it belongs to the post-market of machine tool manufacturing. Since the late 1990s, China's remanufacturing industry has had more than a decade of development. Especially since the beginning of the 21st century, low-carbon environmental protection, energy conservation and emission reduction have become the consensus of the world. Circular economy and green manufacturing have become the hot spots of the society. Remanufacturing has received increasing attention and expectations.

According to statistics, at present, China has more than 8 million machine tools. If the conservative estimate, according to 3% of the machine tool scrap elimination rate calculation, each year will be more than 200,000 machine tools scrapped, idle, technical or functional elimination, accounting for about half of China's annual new machine tool output (40 to 500,000 units) about half . During the "12th Five-Year Plan" period, more than 1 million machine tools will face various forms of scrap. These machines can be re-circulated through remanufacturing, creating a huge remanufacturing market demand.

In recent years, remanufacturing has continued to receive national policy support, and the National Circular Economy Promotion Law has proposed to support enterprises in the remanufacturing of motor vehicle parts, construction machinery, machine tools, and tire retreading. In December 2009, the Ministry of Industry and Information Technology announced the first pilot units for remanufacturing of electromechanical products, including five pilot remanufacturing enterprises for machine tools. In May 2010, 11 departments including the National Development and Reform Commission and the Ministry of Science and Technology listed machine tools as key areas for the development of remanufacturing industries.

Relevant government departments hope to regulate the remanufacturing market through a series of measures such as organizing remanufacturing product certifications, establishing industry access systems, formulating remanufacturing acceptance standards, and issuing preferential tax policies, and encouraging mutual cooperation between machine tool user units and machine tool remanufacturing specialized enterprises. To jointly promote the development of machine tool remanufacturing industry.

At present, remanufacturing has grown from an industry that is not known to more and more understood and accepted by the industry. However, the understanding of remanufacturing by enterprises and users is still relatively shallow.

Chen Can, deputy general manager of Wuhan Huazhong Automation Co., Ltd., said that since there is no policy definition and industry standard so far, the concept of remanufacturing by the market and users is still blurred, and some users are skeptical about remanufactured products, especially for precision and complexity. Whether or not the machine tool can achieve the desired effect after remanufacturing is reserved.

It is understood that the remanufacturing of machine tools in developed countries in Europe and America has become an important part of the remanufacturing industry, with a certain scale and market, and a relatively complete old logistics system has been formed. Remanufacturers recycle used machine tools through various channels, evaluate the value, redesign, and mark the “remanufacturing” label after manufacturing, and re-enter the market.

In China, the construction of the logistics system for scrap machine tools is still in its infancy. There is no smooth channel for the recovery of old machine tools and the sales of remanufactured machine tools. In particular, heavy-duty machine tools, many of which are key equipment of the enterprise, are characterized by individualized customer demands that result in remanufacturing business types and small batches. During the remanufacturing process, the disassembled parts are difficult to place and occupy a large space. This is the particularity of the machine tool industry.

“The positioning, supervision, certification and other systems of domestic remanufacturing enterprises and products are still missing or unclear. Therefore, it is very important to formulate a standard that suits China's national conditions,” said Chen Can.

In 2010, under the guidance of the National Green Manufacturing Technology Standardization Technical Committee, the first national standard for the remanufacturing of machine tools in the field of machine tool remanufacturing was drafted. This standard is applicable to all types of metal cutting machine tools (hereinafter abbreviated as The remanufacturing of machine tools stipulates general requirements for the remanufacturing of metal-cutting machine tools, requirements for mechanical parts, requirements for electrical parts, and other requirements. It is understood that this standard has now been approved.

At present, Huazhong Automation and Chongqing University are organizing the drafting of China's first general technology guideline for heavy-duty heavy-duty machine tools remanufacturing, relying on heavy-duty machine tool remanufacturing engineering technology research centers and undertaking the national science and technology support plan for machine tool remanufacturing complete sets of technology and industrialization issues. Summarize heavy-duty machine tool technology, process, and standards.

Win-win cooperation with users "We recently took orders from Alstom and the company's production situation is very good." Just as soon as they met, Zhang Junnan, general manager of Central China Automation, told reporters with great interest.

As one of the first batch of machine tool remanufacturing pilot companies and one of the first drafters of heavy machine tool remanufacturing standards in the Ministry of Industry and Information Technology, Huazhong Automation has established a modernized heavy machine tool remanufacturing industrial chemical plant, and jointly established the first domestic heavy machine tool remanufacturing with Chongqing University. The Engineering Technology Research Center also received the “Twelfth Five-Year Plan” Technology Support Plan of the Ministry of Science and Technology for the “Complete Set of Machine Tool Remanufacturing Technology and Industrialization”. Huazhong Automation has grown into a leader in the domestic machine tool remanufacturing industry.

At this seminar, the customer company North Heavy Industry Group Company sent a piece of paper to Huazhong Automation, and the person in charge of the Northern Heavy Industry Asset Management Department repeatedly held thanks to the hand of Zhang Haonan, the general manager.

It is understood that Huazhong Automation has successfully completed the relocation and remanufacturing of a 13-meter CNC boring and milling machine for the North Heavy Industry. The relocation of the machine tool not only improves the performance of the machine's electrical control system and the reliability of the machine tool, but also restores the functions of the machine tool and the precision of the machine tool, and meets the precision requirements of the machined workpiece. The cost of remanufacturing this equipment is only one-eighth that of newly purchased similar imported machines, with low investment, short cycle, and high cost performance.

Harbin Electric Group chief mechanical engineer An Yi also told reporters that Huazhong Automation has already completed the remanufacturing of several heavy-duty machine tools for Hadian, and the results are very good.

"Thinking of users, urging users to worry about it, establishing close cooperation with users and win-win relationships is an important tenet of our company." said Chen Can.

Over the years, Huazhong Automation has designed and manufactured and remanufactured over 100 units of imported and domestic heavy-duty and super-heavy-duty machine tools according to the specific needs of users. Mainly covers CNC or ordinary floor milling and boring machines, gantry boring and milling machines, vertical and horizontal lathes, machining centers and flexible processing units. At present, the company has developed 5 special-purpose machine tool projects which have been authorized by the State Intellectual Property Office as invention patents and utility model patents respectively. There are 6 other products that are applying for patents and gradually form core products and proprietary technology advantages.

"The things you give us to do are not big, small, light, or heavy. We only try our best to do everything we can to make it work and satisfy you. This is what we always pursue." Chen Can represents Central China. Self-control made a solemn promise to the user unit.
