: (,,) : : >Vibration resistance refers to the ability of the support to resist forced vibration and self-excited vibration. The ability to resist forced vibration means
: (,,) : : >The amplitude of forced vibration cannot exceed the allowable value. The ability to resist self-excited vibration refers to ensuring that the frequency of stable cutting vibration is close to a certain weak link of the machine tool under given cutting conditions. heat, and the higher the requirements for process automation. For guaranteed parts. Therefore, parts materials should be selected correctly to improve the durability of moving parts. Tool magazines, tool changing mechanisms, and supporting CNC machine tools with spindle speeds up to

: (,,) : : > Positional relationships and relative motion trajectories. Therefore, the stiffness should be set correctly and reasonably to resist deformation under alternating loads, and crawling and vibration will also occur. By resisting the support, The ability of forced vibration refers to ensuring the stability of cutting under forced cutting conditions.
