Lightweight-damping-heat dissipation composite structure micro-milling cutter

Abstract

The present application belongs to the technical field of machine tool cutters, and provides a lightweight-vibration reduction-heat dissipation composite structure micro milling cutter, which comprises a milling cutter head and a composite structure cutter body. The milling cutter head has a flow guide hole, and the composite structure cutter body is filled with a lattice structure, which can reduce the weight by 40%, and a center hole is arranged in the right end face to communicate with the internal lattice structure. During work, the cooling liquid containing metal powder or ceramic powder is pumped into the composite structure cutter body through the center hole, flows through the lattice structure, and finally passes through the flow guide hole of the milling cutter head to directly act on the milling area for cooling. During the process, the vibration energy generated by cutting is dissipated by the mutual collision between the powder particles, the collision between the powder particles and the surface of the lattice structure, and the collision between the powder particles and the inner surface of the composite structure cutter body.
