August 16-19, led by the Jiangxi Federation of Trade Unions and sponsored by the Jiujiang Federation of Trade Unions, the 2021 of Jiangxi Province "Tiangong Cup" labor and skills competition was held in the Industrial Engineering Center of the Shili campus of the Jiujiang Vocational and Technical College. 

    It is reported that the competition is divided into theoretical knowledge competition and practical operation competition, including the assembly and debugging of CNC machine tools, troubleshooting, precision proofreading, parts processing and other comprehensive test skills. And the CNC machine tool fitting and adjusting maintenance workers skills contest is a comprehensive assessment of the skill level of this complex high-skilled workers in Jiangxi Province. 

     When it comes to CNC machine tools, as the basis of industry, has an important position in the development of national economy, and many mainstream CNC machine tools have introduced linear motor. 

     The driving device of traditional numerical control machine tool depends on the screw rod, the screw drive itself has a series of disadvantageous factors, such as length limit, mechanical back gap, friction, twist, longer vibration attenuation time, coupling inertia with motor and axial compression of the screw, all of these factors limit the efficiency of conventional drives, which must be constantly adjusted to ensure that they are needed when the device is worn. LINEAR motor drive technology can ensure a fairly high performance level and has higher efficiency and simplicity than traditional motor drive devices that convert rotation into linear motion, it has the high speed and high precision that the traditional driving device can not reach. 

      Kunshan Tong Mao Electronics Co. , Ltd. with the development of self-marketing Linear Motor, including non-core U Slot and plate with iron core two categories, are using European and American technical standards and processing technology, is widely used in industry, semiconductor industry and other fields.
