Abstract

The invention relates to the technical field of cutting tools and discloses a cutter for hole machining of high-chromium cast iron. The cutter comprises a cutter bar and a blade. Clamping planes are arranged on two sides of the cutter bar respectively, and a mounting groove is formed in one end of the cutter bar; and the blade is fixedly mounted in the mounting groove and is made of polycrystalline cubic boron nitride. The cutter solves the problems that when a ceramic tool is adopted for hole machining of high-chromium cast iron, the feeding amount is small, and the machining efficiency of the high-chromium cast iron is affected in the existing high-chromium cast iron machining process.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a tool for machining holes in high-chromium cast iron. Background technique [0002] High chromium cast iron is the abbreviation of high chromium white anti-wear cast iron. Toughness, strength, at the same time, it also has good high temperature resistance and corrosion resistance, combined with convenient production and moderate cost, it is an excellent anti-abrasive wear material. [0003] Due to the high hardness of high chromium cast iron, the heat treatment can reach HRC59-62. Its normal processing is processed after annealing and softening, and then heat treatment and hardening after processing. At present, ceramic tools are generally used for processing. Ceramic tools have limitations, and the amount of cutting is small. It has advantages in processing large planes and end faces, but it is not suitable for processing apertures. Moreover, ceramic knives are brittle,...
