Exploratory Development to Improve Standard Cutting Tool Materials by Infusion with Metallic Carbides, Ceramic or Diamond

摘要

High-speed steel(HSS) tools with carbide infusion and other treatments were compared experimentally in tool life tests with straight HSS tools. Test results were encouraging and indicated a substantial improvement of performance by tools with tungsten carbide infused on the tool face along the cutting edge. Reduced crater wear was noted in most cases as well as more disposable shorter chips when turning AISI-4340, Bhn 280, and Hastelloy. Tools with various types of laser treatments were prepared.
