The cylinder liner is a cylindrical part of the automobile engine. When the cylinder liner is working, its inner surface is directly affected by high temperature and high pressure gas, and it always has high speed sliding friction with the piston ring and the piston skirt, so the strength, rigidity and resistance of the cylinder liner are There are strict requirements for thermal and wear resistance, and higher requirements are imposed on turning tools for machining cylinder liners. In order to overcome this problem, Fu Nike has set up a special research and development project to further strengthen and improve the processing life of a variety of high-alloy cast iron cylinder liners. The R&D R&D team has continued to innovate and optimize with a large number of cutting tests. The CBN tooling life and processing stability of the cylinder liners have been greatly improved, bringing considerable benefits to customers. Through CBN material innovation optimization → chipbreaker groove type innovation optimization → edge quality innovation optimization, has successfully surpassed an imported CBN tool, and better serve customers with cost-effective products combined with complete system solutions.
