Aiming at the status quo of domestic gear machine research and development, Qizhong Numerical Control Co., Ltd., as a backbone enterprise of domestic machine Tool manufacturing, has a solid foundation of more than 60 years of research and development of machine tools. At the same time, it has rich experience in manufacturing ordinary horizontal hobbing machines up to 1.6m. Therefore, since 2008, the company has invested in research and development, and has developed and succeeded in milling machines, gear hobbing machines and gear grinding machines. Such as: 5m, 6m, 8m, 10m, 12m large-scale CNC vertical gear hobbing machine series research and development and manufacturing, and continue to serve China's key wind power, shipbuilding, metallurgy and other fields. Among them, YK31500L CNC vertical gear hobbing machine (5m) (see metal processing online related report: Qizhong CNC actively promotes the localization of large gear machine tools) participated in Beijing International Machine Tool Show in 2009, and won the "Spring Yan Award", which is recognized by the Ministry of Industry and Information Technology. The first set of machine tools filled the domestic gap. In response to the successful development of CNC vertical gear hobbing machine, the company carried out research and development on the large-scale CNC horizontal hobbing machine series in 2011 through market research, and achieved success. Among them, YK361600L CNC horizontal hobbing machine (1.6m) participated in Nanjing International Machine Tool in 2012. Exhibition, and won the "Spring Yan Award". This series of products has high-tech added value of machine, electricity and liquid integration performance. It adopts the most advanced three-dimensional modeling and finite element analysis as an auxiliary design means to ensure its advanced structure and reasonable selection, so that it will eventually achieve high efficiency and high efficiency. High-tech products with rigidity, high precision and high reliability. Our company has developed and manufactured large-scale CNC gear hobbing machines for more than 4 years. Its various precision indexes have been close to those of foreign professional gear manufacturers. It has been recognized by domestic large-scale gear processing enterprises, and it is the highest-precision CNC with the largest load at home and abroad. Hobbing machine. The product price is only 1/3~1/2 of the similar imported products. The technical indicators are higher than the industry standard. The development and development of this product is positioned in the high-end equipment of key industries, and the overall performance can completely replace the imported products. Standing in the forefront of the world in the field of ultra-heavy and high-precision CNC gear hobbing machines The development of large-scale, high-efficiency and high-precision CNC gear hobbing machines is the first in China, filling the domestic gap in the comprehensive application of some new technologies. The development of this series of machine tools marks that domestic large-scale high-efficiency and high-precision CNC gear hobbing machines have reached the same level of foreign countries and similar products, and the main technical indicators have surpassed similar foreign products, which has played a positive role in promoting the development of the domestic machine tool industry. At the same time, the successful development of this product has greatly improved the overall level of China's equipment manufacturing industry and provided tremendous technical support for the development of China's large-scale shipbuilding industry, wind power, hydropower and other energy industries. It has great strategic significance and significant social benefits. With the increase in demand for equipment manufacturing, shipbuilding, military and engineering equipment in China, the demand for large-scale CNC gear hobbing machines will increase significantly. Among them, the manufacturing machines of aerospace, nuclear power, shipbuilding and other industries are also super large machine tools, which indicates that China's future CNC heavy-duty gear hobbing machine market is huge and has broad prospects. At present, about 8 sets of such products have been signed, and the market demand is expected to be more than 10 units per year. At the same time of low price, CNC high-efficiency gear hobbing machine has 2 to 3 times higher processing efficiency than traditional machine tools, and its performance has reached the international first-class level, showing a very high cost performance. The successful development of this project has led the continuous innovation and development of the production technology of large-scale CNC gear hobbing machine, which has made the manufacturing capacity of China's large-scale CNC gear hobbing machine higher. At the same time, after the project occupied the domestic market, this product will drive the overall market price of gear machine tools to drop. In this way, machine tool users can save the cost of purchasing equipment while using the machine tools with better performance and higher precision. The efficiency and speed of development have also enhanced the confidence of enterprises in domestic machine tools and promoted the development of local machine tool enterprises. The first YK31500L CNC vertical hobbing (5m) developed in this series won the recognition of the first set of machine tools of the Ministry of Industry and Information Technology. In particular, the development and application of the processing software program interface has completely realized autonomy, breaking the situation that the development and application of the hobbing program has been monopolized by foreign countries, opening a precedent for the domestically-made road for the processing of large-scale gears and high-precision gears in China.

An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing. Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.
Angle grinders can be powered by an electric motor or compressed air. The motor drives a geared head at a right-angle on which is mounted an abrasive disc or a thinner cut-off disc, either of which can be replaced when worn. Angle grinders typically have an adjustable guard and a side-handle for two-handed operation. Certain angle grinders, depending on their speed range, can be used as sanders, employing a sanding disc with a backing pad or disc. The backing system is typically made of hard plastic, phenolic resin, or medium-hard rubber depending on the amount of flexibility desired.
