In the machinery industry, machine tools commonly referred to as machine tools, basic mechanical processing equipment manufacturing industry, its variety, performance, quality and technical level directly affects the performance of other mechanical and electrical products, quality, production technology and economics of the business benefits.
Different from the machine tool repair machine tool remanufacturing, it is the value of a remanufactured remanufacturing used as a rough tool, using high technology to repair, performance upgrades, re-acquired the technical performance of manufacturing machine tools to achieve even more than a new machine level. Machine Tool Remanufacturing is also different from recycling, it is the machine as a senior retirement resources to maximize the use of recovery methods, the production cost is much lower than the cost of new machine tool manufacturing.
China's machine tool remanufacturing industry to explore the development of remanufacturing should first determine the meaning. Remanufacturing is not only the scope of manufacturing, are advanced manufacturing, green manufacturing; also belong to the scope of maintenance, is the green maintenance, is the maintenance of the advanced stage of development. So, not only are manufacturing and remanufacturing service industry.
Remanufacturing machine tools can take advantage of the added value inherent in the old machine, lower manufacturing costs, achieve energy and materials. Meanwhile, the old machine is often the backbone of China's manufacturing history, witnessed independent manufacturing process and manufacturing technology, the value of their re-create it carries even more apparent in the autonomy of manufacturing processes and the experience and level of manufacturing technology. Old machine tool remanufacturing and upgrading works will be conducive to China's long-standing independent continuation and development of manufacturing processes and manufacturing technology, manufacturing processes and for the promotion of the autonomy of another manufacturing technology is important.
Demand with diversified characteristics.
Remanufacturing is an old machine tool repair and reconstruction process. The user requirements by machine type and the different effects, and then create the content are different. Therefore, the machine re-manufacturing equipment, it is necessary to understand the structure of the original performance, but also fully meet the needs of new users.
In theory, the machine re-manufacturing is the use of advanced manufacturing technology, numerical control and automation technology and other high-tech repair of old machines and the transformation process.
Experts believe that the machine tool remanufacturing mainly covers the rehabilitation and upgrading of mechanical precision, recovery and improve motion accuracy, CNC system and servo system selection, the selection of auxiliary equipment, and machine commissioning, testing and other aspects of machine tools.
Among them, the precision machine tools to restore and enhance the draft age is increased with the machine, the machine's main components, such as rail, screw, carriage, bearing and others have varying degrees of wear and tear. Therefore, the machine then the primary task of the manufacturing process is similar to the usual overhaul of machine tools in order to restore the precision, reach a new machine tool manufacturing standards.
Machine tool motion accuracy of the restoration and enhancement is another means of CNC machine tools manufacturing, machine tool precision of its requirements and general overhaul of machine tools are different, that is, the accuracy of the machine tool part restoration and improvement of mechanical transmission, must meet the NC machine tool The structural characteristics and requirements of CNC automatic processing, and should have the bulk characteristics of the overhaul.
Because the CNC machine tool numerical control system is the command center, the choice of various functions in addition to considering the time to meet the requirements, but also must work to ensure that the system reliability. Select the appropriate numerical control system is critical, so the selected CNC system and servo system means that, according to the NC machine tool remanufacturing control requirements. The selection of the servo drive system is also manufactured by the CNC machine and then the performance requirements of the decision.
It is understood that the use of the same company supporting the supply of CNC system and servo drive system, then the quality and maintenance of manufactured products more easily guaranteed. Machine commissioning and machine to enter the testing phase, the completion of the initial commissioning test the accuracy of machine tools should be, it generally takes to reach a new machine factory standards.
Industry experts said that a variety of machine tool remanufacturing program, machine types, and then create the content, the user's requirements are different, then create the content will be different.
Therefore, the machine re-manufacturing equipment, it is necessary to understand the structure of the original performance, but also new demands on the user with real understanding, combined with the actual structure of machine tools, in the transformation of the design implementation.
China already has re-manufacturing technology.
In the current research and development of machine tools still need to re-create the key technologies, most of the tools needed to integrate existing technology and machine tool maintenance and reconstruction on the basis of manufacturing technology, combined with the original technology innovation. At present, China has formed the basis of a certain technology, which means that old machine tool remanufacturing is technically feasible.
China's current manufacturing technology of machine tool and then divided into two parts: the existing conventional machine tool manufacturing and repair technology integration and application, and the need for research and development of key technology of machine tool remanufacturing.
Among them, the existing conventional machine tool manufacturing and repair technology integration and application of machine parts and components involved in repair and re-manufacturing technology, machine functional recovery and maintenance technology, use of the existing NC Transformation in three dimensions.
And yet to develop the key machine tool remanufacturing technologies include comprehensive evaluation and re-used tool design technology, information technology upgrading, including re-create the rough quality of testing, machine tool remanufacturing process, quality control, quality inspection machine tool remanufacturing, including quality control, machine life prediction and remaining life assessment technology. Most of these technologies require the integration of maintenance and renovation of existing machine tools and machine tool manufacturing technology, based on the combination of the original technological innovation, forming machine tool remanufacturing and upgrade the expertise and equipment.
Technical means to fully meet the existing machine remanufacturing needs. Experts said that particularly in recent years mechanical features of advanced machine tools, drive system and control system development, both for the old machine tool remanufacturing provides a good technical support and room for improvement. In other words, China has formed the basis of a certain technology, numerical control technology has also been very mature, old machine tool remanufacturing is technically feasible. Re-create the old time machine has been more mature.
It is understood that, for the old machine tool remanufacturing, we must first restore or improve the mechanical precision parts repair defects have emerged, followed with a cost-effective to control systems and servo systems, and replace with the new system, transmission system compatible and so on. Such as the use of existing technology to enhance transformation of NC NC machine tools and general automation, CNC or CNC machine tools to upgrade the device. Optimization by drive, drive motor optimization matching technology, the transmission system transformation technology and energy saving devices developed new energy-saving machine technology, optimization of energy saving machine tools. Nano surface technology, complex surface technology and other surface engineering technologies (such as spraying, brush plating technology, high-strength nano-repair agent technology, etc.) repair and strengthen the Machine Tool, slide plates, tailstock and other wear and tear, scratch the surface, and increase its size, shape and location accuracy.
Cost savings of up to 80%.
High added value for general machine tools or CNC machine tools, by re-manufacturing, the average performance level comparable to the purchase of new machines also cost 60% to 80%, and the new machine can basically reach the original level of performance. At the same time, users can flexibly select the desired function.
The machine is durable, and its iron and steel materials value and mechanical parts of the value of value-added manufacturing costs higher, with high recycling value. Experts pointed out that the whole machine can either be re-manufactured parts can be remanufactured.
Integrated in the machine re-manufacturing, can improve the general machine tools, CNC machine tools, large (heavy) type of machine NC machine tools, automation, green standards, and achieve functional recovery and improved. Parts Remanufacturing refers to the main parts and components and other methods can be repaired to restore its performance.
It can be said, the machine parts remanufacturing more space, such as bed, rails, table, column, base, worm and other components can use high technology or scraping the surface treatment, precision planing, grinding and other mechanical methods processing, to restore its surface properties.
The longer the aging stability of the old parts as possible, after remanufacture of machine performance and stability and reliability.
It is understood that more than 75% of the weight machines can be re-manufacturing. The bearings, fluid pressure lubrication system and cooling system components, clutch and brake unit (gate), seals and gaskets and other parts if you need to use the same type of damage to new parts instead. Meanwhile, the machine tool remanufacturing is very typical, because the tools are standardized products, functional parts interchangeability, and can greatly simplify the manufacturing process again.
From an economic perspective, the machine tool remanufacturing invested, short period. The costs include the cost of repairing the mechanical parts, electrical parts and CNC conversion costs, purchase and installation costs of the new features, then create the design and commissioning costs.
According to statistics, a high added value for the general machine tools or CNC machine tools, machine tools through the full use of re-manufactured the original parts, saving the cost of manufacturing these parts, the average performance level comparable to the purchase of new machines also cost 60% to 80 %, and after re-create the original machine can basically reach a new level of performance machines. At the same time, the user can the state of the machine and process requirements to select the numerical system or other features, and further cost savings.
Also, precision machine tools and large (heavy) type machine tool remanufacturing cycle than manufacturing a new much shorter, like a boring bar table 250mm diameter CNC Boring and Milling, if the purchase of new machines, from order to delivery at least 18 months time. If use of the old machine tool remanufacturing, only 8 to 10 months. During this period of time can often save the cost recovery. Moreover, the general large-scale machine tool remanufacturing costs only one third of the cost of new machines purchased.
On the whole, and then create both the machining accuracy of machine tools, processing efficiency is greatly improved, while the processing time, especially a variety of auxiliary time will greatly reduce processing efficiency by 30% or more. At the same time, and then after manufacturing of CNC machine tools can also be sophisticated batch processing tools, greatly reduce the processing cost.
Market demand accounted for half the annual output of new machines.
China has become the world's largest machine tool consumer market, the current machine to maintain nearly 700 million units. If the machine by 3% per year in retirement to estimate the rate of elimination, each year nearly 20 million machine tools into the ranks of re-manufacturing, accounting for an annual production output of about half of the new machines.
The basic machine is the mechanical processing equipment manufacturing, and machinery industry is an important basis for national economic development and support for the national economy's ability to provide technical equipment and the level depends largely on the level of the machine. Since 2001, continued with the construction of major projects, machinery industry as a whole has shown a rapid development, machine tool industry has also developed rapidly.
By a large machine tool industry, National Bureau of Statistics data, 2007 4291 total industrial output value of enterprise 274.77 billion yuan, an increase of 35.5%. Production of metal cutting machine tool 606,835 sets, up 11.7%, of which production of CNC metal cutting machine tool 123,257 sets, an increase of 32.6%. China's machine tool output remain third in the world, exports rose to eighth in the world, consumption and imports to keep the world for 6 years. China has become the world's largest machine tool consumer market, consumption of the output value of one fifth of the world machine tool.
In recent years, high-precision machine tools, CNC machine tools and large-scale production of machine tools although growing rapidly, but the base is too small in the share of machine tools is still not high. Experts pointed out that the ordinary type of machine is still the leading machine tool products, this ratio is not changed dramatically in a short time.
At the same time, our rate of CNC machine tools is also very low. According to the China Machine Tool Association statistics, from 2000 to 2006, China's equipment manufacturing plant produced a total of 290,400 sets of CNC equipment, exports about 3 million units sold in the domestic as 260,400 units; total imports of CNC equipment 2 .. 20000 Taiwan.
