    Recently, our Intellectual Property Office announced the 2022 China Intellectual Property Office Patent Research Project Project results. “Advanced CNC machine tool patent analysis research”“CO2 high-value utilization of the key technology of negative carbon patent analysis research” and other projects were approved. 

    Among them, the small editor wants to focus on telling everyone about the project of“Patent analysis and research on advanced numerical control machine tools”, the project is led by the Intellectual Property Information Service Center of Northeastern University, the Library of Northeastern University and the Institute of Science and Technology of Northeastern University, and jointly undertaken by the China (Shenyang) Intellectual Property Protection Center, belongs to the key core technology patent analysis projects, focusing on advanced CNC machine tools, “Neck” problem. It is reported that the Intellectual Property Office received a total of 203 such projects, only 15 projects, project approval rate of only 7.4% . Speaking of CNC machine tools, LINEAR MOTOR-DRIVEN CNC machine tools is one of the mainstream CNC machine tools.

     The driving device of the traditional numerical control machine tool relies on the screw drive, the screw drive itself has a series of disadvantageous factors including length limit, mechanical back clearance, friction, distortion, long vibration attenuation time, coupling inertia with the motor and axial compression of the screw, etc. , all of these factors limit the efficiency of traditional drives, which are constantly adjusted to ensure that they are needed when equipment is worn out. LINEAR motor drive technology can ensure a high level of performance and than the traditional rotating into linear motion of the motor drive device has a higher efficiency and convenience, it has high speed and high precision which can not be achieved by traditional driving device.
