\nHeavy interrupted turning of hardened steel parts (e.g., shafts with keyways and oil holes after heat treatment, as well as gear tooth surface turning) subjects tools to extremely high cutting temperatures (typically exceeding 1000\u00b0C) and high-frequency mechanical shocks. Under these challenging conditions, a tool\u2019s ability to handle extreme machining operations is fully tested. The following factors need to be considered when selecting tools:
\n\u25cfHot hardness and wear resistance of the tool material, including CBN content and grain size;
\n\u25cfToughness and impact resistance of the tool, including binder composition and insert structure;
\n\u25cfTool performance improvement via edge design and advanced coating technology;
\n\u25cfOptimization of cutting parameters.\"\" \"\"<\/p>\n

\n\u25ce In this case, turning the annular grooves in the middle of the gear shaft under heavy interrupted cut conditions generates severe high-frequency alternating mechanical stress as the tool enters and exits the workpiece. Worldia\u2019s tooling solution uses the PNH3013 insert grade, which offers excellent toughness and impact resistance, increasing tool life by 13.3% compared to the original solution.
\n\u25ce Considering the frequent entry and exit of the tool when machining gear tooth surface, and the resulting high-frequency changes in cutting force, Worldia\u2019s solution increases the tool nose radius and uses non-standard edge parameters to effectively improve insert strength and edge chipping resistance.
\n\u25ce Worldia\u2019s customized superhard cutting tools provide scientific and reliable tooling solutions for customers\u2019 difficult-to-machine materials and complex machining conditions, leveraging the characteristics of our own products. This helps customers optimize their machining processes: extending tool life, reducing tool changes and downtime, lowering tool costs, and improving production efficiency.<\/p>","protected":false},"excerpt":{"rendered":"
