Flap Wheels with shaft are made of multiple abrasive sheets attached to a core for fabricating, deburring, cleaning, polishing, and finishing jobs in metalworking applications. The sheets wear away during jobs, constantly exposing fresh abrasive coating to provide an even finish. Each grit flap comes in contact with the work piece at a slightly different angle, which prevents scratches. Because abrasive flap wheels conform to the shape of the surface material, they are commonly used to finish complex shapes and tight contours on a work piece. Flap wheels attach to grinders, drills, impact wrenches,or handheld rotary tools. They are either pre-mounted on a central hub, or unmounted for attaching to a compatible arbor.
Suitable for grinding the inner hole and camber of all kinds of metal and non-metal materials, select the suitable size of flap wheel with shaft for grinding. Remove burrs, rust, metal (plastic) and other surface grinding, internal and outter surface grinding, the grinding before painting, etc.Polishing, deburring, and removal of pits, burrs, and scratches. Remove parting lines and provide a uniform scratch pattern on all metals. The 1/4 inch stem allows for easy mounting on a die grinder or right angle die grinder.

I. Changes in the economic environment and increased market supply and demand
After the implementation of the new labor law by the Chinese government in 2008, labor costs have increased substantially and the economic environment has changed. This aspect has led some manufacturers to shift labor-intensive industries to Southeast Asian countries where labor costs are lower, and on the other hand, local companies are paying more attention to improving the level of factory automation.
In addition, more and more international automakers have landed in China, and fierce market competition has stimulated the demand for industrial robots by Chinese automakers. For example, Chery will produce 100 self-contained welding industrial robots in 2010. At the same time, more international suppliers of industrial robots are also accelerating their entry into the Chinese market. For example, Comau, which specializes in automotive spray and welding industrial robots, will build the Kunshan plant by the end of 2010.
Second, the speed of technological development
Funded by the National 863 Program, more than 30 universities including Harbin Institute of Technology and Yanshan University have started research on industrial robots.
Some CNC machine tool and system manufacturers are beginning to target future profit points to industrial robots. For example, Shenyang Machine Tool has plans to develop industrial robots; Huazhong CNC and Guangzhou CNC have also begun to develop and manufacture industrial robots.
International motion control software and sensor manufacturers continue to increase their communication with China, and Chinese industrial robot manufacturers will receive support for technical bottlenecks that were difficult to break through. Introduce advanced sensors and control technologies into the robot through integration, and realize the self-learning function of industrial robots that are more concerned in industrial applications.
Third, government policy stimulus
China's "National Medium- and Long-Term Science and Technology Development Plan (2006-2020)" and "863 Program Advanced Manufacturing Technology Development Outline" propose to provide 100 million yuan of financial support for industrial robotic engineering products and automated production lines and manipulator key technologies. . At the same time, the provinces have also proposed their own support plans for the development and manufacture of industrial robots. For example, Shandong Province will establish a robotic technology innovation alliance, a key laboratory and an engineering technology research center through the government capital injection form before 2012, and implement 15% corporate income tax reduction and other preferential measures for industrial robots for processing and manufacturing.
China's industrial robot status
At present, inconsistent with the status of manufacturing powers, China's industrial robots are still under-represented, and mainly rely on imports from Japan, Sweden, Germany, Italy, and the United States. Among them, Japan accounts for about 50%, and Europe accounts for about 40%. Manufacturers mainly include FANUC, YASKAWA, ABB, COMAU, KUKA and Staubli. At the same time, China's industrial robot manufacturing industry has just started, and its manufacturing level and technical content are relatively backward. Take Xinsong, the largest and most technologically advanced manufacturer, as an example. In 2009, it only produced more than 600 industrial robots, which is far from the international annual output of thousands of units.
China's long-term labor-intensive production model, numerous skilled workers and low wages, as well as employment promotion policies, have led to the current situation of enterprises upgrading production equipment, improving the level of manufacturing automation, and the small number of industrial robot applications.
Low-carbon economy promotes the development of China's machine tool industry
For the high-volume, low-tech, extensive development model of the Chinese machine tool industry, to meet the Chinese government's demand for low-carbon economy development, make full use of the "high-end CNC machine tools and basic manufacturing equipment technology special projects" funds, increase new product development The strength to quickly provide high-performance processing equipment will promote the development of the industry.
The new energy and energy conservation and environmental protection industries, including hydropower, wind power, nuclear power and solar power, are the industries that the National Energy Commission established in January 2010 and are also the focus of the manufacturing industry on the low carbon economy.
The metal processing industry, especially the CNC machine tool, as the working machine of the manufacturing industry, will undertake the processing and manufacturing of large and precision parts in the new energy and environmental protection industries. As a result, Chinese heavy-duty machine tool manufacturers have introduced corresponding machine tool products in recent years. Such as Wuhan XKD2755570-2M CNC gantry mobile boring and milling machine for heavy-duty machine tools, for large gear processing in the wind power industry; Qimen Machine Tool Group's gantry mobile turning and milling machining center CXK5463X50/150, can be used for nuclear power, hydropower equipment, large and complex Processing of parts. These large-scale CNC machine tools will be equipped with new energy and energy-saving equipment manufacturers such as China One Heavy, Double, Dongfang Steam Turbine and Harbin Power Group. At the same time, solar power plants, new energy vehicles, etc. also have a large demand for large, multi-axis, precision CNC machine tools.
Some key components in the new energy and environmental protection industries require processing precision and processed materials to exceed the processing capabilities of general metalworking machines. For example, in the processing of precision tungsten steel holes in solar battery back plates, precision machining of very small diameter holes (such as 0.3 mm diameter) sometimes occurs, which requires special machining such as precision electric spark small hole processing machine or small hole honing machine. machine tool. From the 2010 China International Industry Fair, we learned that special processing equipment such as laser processing machine tools, water-cutting machine tools, and electric discharge machine tools are paying attention to the processing needs of the new energy industry, and processing parts that are difficult to process materials and require ultra-precision precision.
In 2010, China's industrial robots will have more than 10,000 units, accounting for about 0.6% of the global total. At the same time, the demand will exceed 3,000 units. China's industrial robot market will enter a period of rapid development. This is mainly based on the following three reasons.
