For example, the addition of Al2O3 sintered ceramic tools to silicon nitride, combined with the characteristics of Al2O3 and SiN4, is higher than that of hard alloy tools and alumina ceramic tools, and the cutting edge temperature is higher than 1000 °C. Its biggest advantage is to increase the cutting speed, increase the feed rate, increase the metal removal rate and extend the tool life. Silicon nitride ceramic tools are particularly suitable for cutting a variety of cast irons and superalloys, but can not process steels that produce long chips.
All in all, with the deepening of the research and development of special ceramic materials, the proportion of ceramic tools in the metal cutting and processing industry has been expanding. With the development requirements of the aerospace and aerospace industries, it is necessary to meet the requirements for improving the cutting efficiency of workpiece materials such as Ti alloys and Ni-based superalloys, and special ceramic tool materials will make greater contributions.

Wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.
Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. A simple solution is to use a threaded insert.
