Slide system of nc carving and milling machine tool

8 hz, the main mode for the vertical skateboard with transverse slide along the direction of translation. The first order natural frequency and modal vibration mode as shown in figure 6 ( Just give the first order natural frequency and modal vibration mode) 。 0 hz, the main mode for the vertical skateboard and cross slide along the z direction, the vertical slide amplitude slightly; 8 hz, the main vibration mode to create vertical skateboard for beams with transverse slide along the y direction vibration; 1 hz, the main vibration mode to create CNC carving and milling machine tool for beam, vertical and cross slide board together along the direction of vibration; 7 hz, the main vibration mode for CNC carving and milling machine tool vertical and cross slide board along the Z direction vibration, but opposite direction; 3 hz, the main vibration mode for CNC carving and milling machine tool vertical vibration in the Y direction board; 2 hz, the main vibration mode for CNC carving and milling machine tool vertical and cross slide board along the direction of vibration, but opposite direction; 5 hz, the main vibration mode is CNC carving and milling machine tool at the top of the cross slide. CNC carving and milling machine tool system of skateboard in the first eight order natural frequency of vertical skateboard and cross slide vibration frequency is low, this is because their elastic connection between stiffness value is small. The third order and fourth order natural frequency of the vibration of the columns, and the frequency is not high, thus, column is the weak link of the skateboard systems.
