Abstract
A lightweight vibration damping cutting tool bar includes a tool body, on which a plurality of cavities are opened along the length direction, and the cutting tool body between adjacent cavities have a BCC lattice structure, the closed magnetic pole device includes a plurality of magnetic pole pieces located at the bottom and side walls of the cavity respectively; the pendulum damper is placed inside the closed magnetic pole device composed of a plurality of magnetic pole pieces, the outer surface of the pendulum damper is provided with a magnetic pole patch corresponding to each magnetic pole piece one by one, the magnetic pole patch is set relative to the side with the same polarity of each magnetic pole piece, so that the magnetic force of each magnetic pole piece and the magnetic force of the corresponding magnetic pole patch are repelled.
