Description

Knife seat shock absorption and damping structure

The creation of the damping and damping structure of the tool holder is mainly applied to the technology of damping by using the damping element and the elastic damping ring to generate a counterbalanced force when the tool holder cuts the vibration.

The existing cutter bar will produce vibration phenomenon during processing. The obviousness of the vibration phenomenon depends on the length of the cutter bar. The vibration phenomenon of the shorter length cutter bar is less obvious, and the vibration phenomenon of the longer length cutter bar is very obvious. , The greater the impact, but for the processing of some large workpieces, the length of the shank is relatively longer, and the vibration cannot be avoided during processing.
