On June 3, 2026, information from the State Intellectual Property Office showed that Qinchuan Machine Tool Group Co., Ltd. and Shaanxi Qinchuan Precision Equipment Co., Ltd. applied for a patent titled “A magnetically suspended gas static pressure CNC turntable and its control method.”
The application publication number is CN122125501A, the application number is CN202610519889.7, the application publication date is June 2, 2026, and the application date is April 20, 2026.
The patent summary shows that the present invention discloses a magnetic levitation gas static pressure CNC turntable and a control method thereof, including: a base, a rotatable turntable is provided on the base, and a positioning shaft is installed in the center of the turntable; wherein,
Electromagnetic coil assemblies are distributed and installed in the base, and permanent magnet assemblies corresponding to the electromagnetic coil assemblies are arranged in the turntable; static pressure chambers are provided on the end faces and sides of the base, and the high flow resistance seal between the base and the turntable is achieved by the air film gap of the static pressure chamber.
By setting up a magnetic levitation-gas static pressure hybrid support structure, the turntable assembly is set as the rotor, and the shell base is set as the stator, suspended rotation can be achieved. This structure not only retains the high-precision characteristics of gas static pressure, but also introduces the active control capability of magnetic levitation, significantly improving the dynamic performance and stability of the turntable under complex working conditions.
