The characteristic of tools wear is analyzed through turning fluorophlogopite glass-ceramics. And the process of tools wear can be divided into three periods. Through single factor test, the influence of tools wear was discussed such as tool material, cooling conditions, cutting depth and feed speed. The study indicates, the tools material and cooling condition are major factors to affect tools wear. The high-speed steel tool is not suitable for turning fluorophlogopite. Because sustaining time of cutting is short and efficiency is low in machining, the tungsten-cobalt carbide tool is not perfect tool. And ceramics tool is better than the both. The tools wear rate can be decreased under cooling conditions. Influential curve of tools wear rate versus cutting depth is a part of parabola curve.
