陶瓷刀片具有高温硬度高、耐磨性和化学惰性好的特点,它适合于在较高切削温度下进行高速切削。适用于淬硬钢和冷硬铸铁等硬脆性材料的加工,并可获得较好的稳定尺寸,因此被国外视为八十年代的刀具材料。我国陶瓷刀具应用面还不广,因此通过试验,选择较合适的切削用量和较合理的刀 Ceramic blades have the characteristics of high temperature hardness, wear resistance and chemical inertness, it is suitable for high-speed cutting at higher cutting temperatures. Suitable for hard and brittle materials such as hardened steel and chilled cast iron processing, and get a better stable size, it is foreign as the eighties tool material. China’s ceramic tool is not widely used surface, so through the test, choose a more appropriate cutting and more reasonable knife
