【Abstract】 As an important breakthrough in the development of tips materials, the technique of coating the tips’ surface is thought to be an effective measure in solving the problem of making tips materials characterized by red hardness, wear resistance, strength and endurance. Better cutting ability could be obtained by adopting multiply composites coating instead of mono coating. Owing to the restriction of coating equipment and coating techniques, it is the first time in our country to study the cutting ability of tips with four or more layers of coating. The paper depicts the cutting experiment on four kinds of multiply tips.更多还原
