Where diamond shines | American Machinist

A recent ceramic machining test compared the performance of a Norton Diamond Film DF1000 CVD diamond coated end mill with that of an uncoated tungsten carbide end mill and a TiN-coated one of the same geometry ( 3 /8-in., four-flute). The test part was a SiC-containing bisque ceramic, which was presintered at temperatures greater than 1,200° C. Machining parameters were as follows: 10,000 .
