Recently, innovative achievements in the field of electric spindles have been continuously emerging, and multiple enterprises have injected strong impetus into the upgrading of the manufacturing industry through technological breakthroughs and patent approvals. These developments not only solve the long-standing problems faced by the industry, but also indicate that electric spindles will play a more critical role in the manufacturing field.
The China National Intellectual Property Administration announced in April 2025 that "a kind of motorized spindle maintenance tool" CN222712103U) was officially authorized. This fixture adopts a modular design with replaceable support mechanisms, breaking the limitations of traditional maintenance fixtures that require multiple devices for different sizes of electric spindles. It greatly reduces equipment costs and footprint, significantly improving the practicality and applicability of maintenance fixtures. At present, as the core component of CNC machine tools and other equipment, the maintenance efficiency of electric spindles is directly related to production efficiency and maintenance costs, providing innovative solutions to the long-standing complex problems of tooling management in the industry.
Also approved in April is the "Electric Spindle for a Grinding Wheel Trimmer" (CN 222696888 U). Through integrated design, the motor, bearings, and spindle cover are integrated, greatly simplifying the overall structure of the grinding wheel dresser. This not only greatly reduces the installation space, but also eliminates the need for the original clamp mounting seat, allowing the electric spindle to be directly installed on the workbench, significantly improving installation convenience.
In addition to achievements, the company has also achieved fruitful results in market expansion and technological upgrading, focusing on the design, research and development, and manufacturing of electric spindles. Its core products are widely used in fields such as 3C, automotive, aerospace, and medical equipment. Its new generation of axis cooled electric spindle technology fills the domestic gap by cooling the spindle rotor and bearings with circulating water, reducing temperature rise, thermal elongation, and vibration, and improving spindle rigidity and speed.
As the manufacturing industry moves towards intelligence, electric spindles have increasingly broad application prospects due to their advantages of high speed, high precision, and low noise. According to data from the National Bureau of Statistics, the shipment volume of metal cutting machine tools in China will reach 613000 units in 2023, with a spindle market size of approximately 9.642 billion yuan, an electric spindle penetration rate of 14%, and a market space of 2.789 billion yuan. It is expected that by 2030, the electric spindle market size will exceed 10 billion yuan, accounting for 57% of the spindle market. Driven by the demand in fields such as new energy vehicles and aerospace, innovation in electric spindle technology will continue to lead the upgrading of the manufacturing industry and open up new growth opportunities for industrial development.
