AI Technical Summary

Technical Problem

When processing honeycomb aluminum plates, the small axial angle of the cutting teeth leads to large processing resistance, insufficient chip removal performance and service life, and the linear structure of the tooth seat is not conducive to the flow of wood chips.

Method used

Design a pre-milling cutter for honeycomb aluminum plates, with the axial angle of the cutter teeth set at 40° to 60°, and adopts arc-shaped tooth seats and flow-guiding inclines, and sets a barrier port and an open chip drainage groove to improve chip drainage effect and material smoothness. .

Benefits of technology

Through the continuous processing of large axial competition points and the arc-shaped tooth seat design, the processing resistance is reduced, the chip removal effect is improved, the tool service life is extended, and the finish of the processing materials is ensured.

Abstract

The utility model discloses a pre-milling cutter for a honeycomb aluminum plate, belongs to the technical field of machining cutters, and solves the problems that the existing pre-milling cutter is large in machining resistance and poor in chip removal effect. The cutter comprises a cutter body, a plurality of groups of lower cutting parts are arranged on the upper portion of the cutter body, a plurality of groups of upper cutting parts are arranged on the lower portion of the cutter body, each lower cutter comprises a lower tooth holder and a lower cutting edge, and each upper cutter comprises an upper tooth holder and an upper cutting edge. Chip grooves are formed in the cutter body on the side, far away from the lower tooth holder, of the lower cutting edge and the cutter body on the side, far away from the upper tooth holder, of the upper cutting edge, flow guide slopes are arranged on the edges of the sides, far away from the lower cutting edge and the upper cutting edge, of the chip grooves, and the cutter tooth axial angle mu of the lower cutting edge and the upper cutting edge ranges from 40 degrees to 60 degrees. And avoiding openings are formed in the lower tooth holder and the upper tooth holder close to one side of each lower cutting edge and one side of each upper cutting edge on the two sides of the cutter body. According to the pre-milling cutter, the machining resistance of the cutter can be reduced, the chip removal effect is improved, and the smoothness of machined materials is guaranteed.
