Description

High-performance ceramic cutting tool

Technical Field

The utility model relates to a cutting tool technical field specifically is a high performance ceramic cutting tool.

Background

In the existing numerical control machine tool cutters, alloy cutters are the existing mainstream technology, along with the updating and upgrading of the technology and the requirement on efficiency, more and more machine tools are upgraded and rotate at a higher speed, but the performance of the traditional hard alloy cannot be borne at a high rotating speed, and even the yield strength is greatly reduced at a high temperature, so that the cutters are softened, and the machining is difficult. In high speed machine tool applications, conventional cemented carbides suffer mainly from the following disadvantages: 1. the conventional hard alloy has obvious abrasion on the periphery in use, and the processing time is too long or even cannot be processed for high-hardness materials. 2. The high temperature at high rotation speed leads to the obvious reduction of the hardness of the conventional hard alloy milling cutter and the reduction of the milling capability. 3. In order to avoid softening the cutter at high temperature, water needs to be continuously sprayed to the cutting position to achieve the cooling purpose, and water resources are wasted.
