 Specific implementation mode two: as figure 1 As shown, the DC dual output shaft motor 38 in this embodiment is a DC dual output shaft brushless drive motor. With such a design, the driving effect is good. Other components and connections are the same as those in the first embodiment.
 The DC dual output shaft motor 38 of the present embodiment is composed of a stator 1 and a rotor 2, and the rotor 2 of the DC brushless drive motor system 38 is fixedly connected with the first motor shaft 19 and the second motor shaft 20 at the same time, and the brushless drive motor is used as The driving element, since there is no brush, there is no frictional moment between the stator 1 and the rotor 2 of this motor, and the rotational torque can be directly generated to drive the first main shaft 10 and the second main shaft 28 to rotate simultaneously and perform cutting.
specific Embodiment approach 3
 Specific implementation mode three: as Figure 4 As shown, the ranges of the first gap D, the second gap E, and the third gap F in this embodiment are all 4-6 μm. Such a design effectively improves the rigidity of the hydrostatic oil film and realizes the ultra-precise rotation of the first main shaft 10 . Other compositions and connections are the same as those in Embodiment 1 or 2.
