The production of smartphones and automobiles has been increasing, and the demand for related components has been rising, driving the demand for China's drilling centers to continue to increase.
Drilling and tapping centers, also known as drilling and tapping machines and drilling, milling and tapping centers, belong to metal cutting machines and are common standard CNC machines in the machining industry. The drilling and tapping center integrates cutting, drilling, tapping, and other functions, and has the advantages of high processing accuracy and fast processing speed. It is mainly used to process small metal workpiece.
The drilling center is mainly used for processing aluminum and aluminum alloy materials. Aluminum alloy is an excellent metal material with light weight, high strength, good plasticity, electrical conductivity, thermal conductivity, and corrosion resistance. It can be widely used in electronic and electrical, mechanical equipment, automotive transportation, aerospace, construction, and other fields. Since 2016, China's aluminum alloy production has continued to grow. According to data from the National Bureau of Statistics, in 2021, the national aluminum alloy production was 10.68 million tons. The continuous increase in aluminum alloy production and processing demand is conducive to the development of the drilling center industry.
According to the form of tool change, drilling and tapping centers can be divided into drilling and tapping centers with clamping arm type tool libraries, drilling and tapping centers with servo type tool libraries, and drilling and tapping centers with synchronous disk tool libraries. Among them, the drilling and tapping center with a clamping arm type tool magazine can achieve a non jump tool change, which is the most common type of drilling and tapping center.
Compared with machining centers, drilling and tapping centers are characterized by smaller volume, lighter weight, and smaller tool magazine capacity; High displacement speed, high spindle rotation speed, enabling high-speed machining; The cutting force is small, mainly processing aluminum alloy workpieces with small dimensions, but also processing stainless steel workpieces. The drilling center is mainly used in the manufacturing of mobile phone parts and automotive parts.
Taking smart phones as an example, the drilling center can be used for processing components such as the middle frame, frame, and shell of mobile phones. China is the world's largest manufacturer of smartphones and automobiles. According to data from the Ministry of Industry and Information Technology, in 2021, China's smartphone production will reach 1.27 billion units, up 9.0% year-on-year; According to data from the China Automobile Association, in 2021, China's automobile production reached 26.082 million units, up 3.4% year-on-year. The production of smartphones and automobiles has been increasing, and the demand for related components has been rising, driving the demand for China's drilling centers to continue to increase.
Technical barriers to drilling centers are high. In the early stage, China's market demand mainly depended on imports. Imported drilling centers were expensive, and their after-sales services were poor, making them difficult to maintain, unable to meet the development needs of the domestic manufacturing industry. With the continuous progress of research and development technology of drilling and tapping centers in China, the penetration rate of domestic drilling and tapping centers in the domestic market continues to increase.
