Cutting tool for milling |
摘要 |
<p>A cutting tool for milling comprises an insert consisting of a cubic boron nitride sintered body having heat conductivity of at least 400 W/m.K at 120 DEG C and a thermal expansion coefficient within the range of at least 3.0 x 10<-6>/K and not more than 4.0 x 10<-6>/K in the temperature range of from 20 DEG C to 600 DEG C. According to this cutting tool for milling, sufficient tool life can be attained in high-speed face milling under a wet condition and high-speed end milling under a wet condition. <IMAGE></p> |
