In recent years, with the rise of CNC engraving and milling machines, it has driven the rapid development of related industrial chains. Among them, the high-speed electric spindle is the most prominent.

Due to the ability of CNC engraving and milling machines, their main feature is the use of smaller cutting tools and high-speed electric spindles for engraving and milling processing. Among them, the working speed of the electric spindle is generally between 20000~60000rpm, and can even reach over 120000rpm, and high-speed electric spindles are required to ensure high precision within ± 10% deviation during operation.

Zhong Hong, Secretary General of the Spindle Functional Components Professional Committee of the China Machine Tool Industry Association, said that the widespread application and rapid development of CNC engraving and milling machines have brought huge development opportunities to high-speed electric spindle manufacturers. Generally, each engraving and milling machine is equipped with 1-2 electric spindles, not including damaged replacement parts. The demand for double head engraving and milling machines and multi head engraving and milling machines is even greater.

According to the annual demand for CNC engraving and milling machines, the market size of CNC engraving and milling machine spindles is also very large. Based on the production and sales of 50000 carving and milling machines in 2010, it is estimated that the production and sales volume of electric spindles will exceed 100000. If the sales of CNC engraving and milling machines reach 120000 units in 2015, then the required electric spindles will exceed 240000.

Zhong Hong also said that since the 2011 China International Machine Tool Show and market analysis, almost all domestic engraving and milling machines now use independent brand electric spindles. China's CNC engraving and milling electric spindle market has initially formed an industrial scale, such as Jiangsu Xingchen, Wuxi Bohua, Jiangsuhua Diao, Jiangsu Xuchang, etc., which can produce different levels of electric spindles from ordinary to high-precision for engraving and milling machines. But he believes that the current production capacity of domestic power generators is only around 90000 units, which is still a big gap compared to 240000 units.

In addition, the leapfrog development of CNC engraving and milling machines has also driven the development of other industries including CNC systems, cutting tools, software industry, etc.
