CNC machine tools are flexible, high-efficiency and stable-quality automated machine tools, which have better solved the problems of complex, precise, small batch and multi-variety parts, representing the development direction of modern machine tool control technology. 

      CNC machine tools can be divided into bed CNC lathes and flat bed CNC lathes according to the layout of the machine tool. The two have their own strengths in terms of chip removal capacity, cuttingidity and automatic production. 

     However, in terms of machining accuracy, the flat bed CNC lathe has always been slightly inferior to the inclined bed CNC lathe Because the transmission lead screw of the CNC lathe is a high-precision ball screw, the transmission clearance between the lead screw and the nut is very small, but it does mean that there is no clearance. As long as there is clearance, when the lead screw moves in one direction and then reverses transmission, it is inevitable that there will be reverse, which will affect the repeat positioning accuracy of the CNC lathe and thus affect the machining accuracy. The layout of the inclined bed CNC lathe directly affects the clearance the X-direction ball screw, and the gravity directly acts on the axial direction of the lead screw, making the reverse clearance almost zero during transmission. The X-direction lead screw the flat bed CNC lathe is not affected by the axial gravity, and the clearance cannot be directly eliminated. However, with the rapid development of linear motors, linear are widely used in CNC lathes to replace ball screws as driving devices, greatly improving the accuracy of flat bed CNC lathes. The driving device of traditional C machine tools relies on screw rod drive, which has a series of unfavorable factors including length limit, mechanical backlash, friction, distortion, longer vibration attenuation time, coupling inertia with motor and axial compression of the screw rod, all of which limit the efficiency of traditional driving devices. When the equipment wears, it is necessary to constantly adjust to ensure the desired. motor drive technology can guarantee a fairly high level of performance and has higher efficiency and simplicity than traditional motor drive devices that convert rotation into linear motion. It has the high speed and precision that traditional drive devices cannot achieve. 

      Although our Kunshan Tongmao Electronics Co., Ltd. does not manufacture CNC machine tools, it has been deeply involved the field of linear motors for more than a decade. Kunshan Tongmao Electronics Co., Ltd.'s independently researched, produced and sold linear motors include two categories:less U-shaped grooves and ironed flat plates. Both adopt European and American technical standards and processing technology, and have high performance and quality.
