Cutter Sets New Standard for Heavy Hogging

摘要

A recent roughing application shattered this moldmaker's expectations about the stability of a large face mill in long-reach contouring operations. "The chips came off so big and heavy, it took a shovel to clear them. They came off so fast, we had to buy bigger bins. Unbelievable!" So says John Novosel Jr., president of Nova Tool and Mold, about the company's recent success with machining a large mold core on a 75-hp vertical mill. Yet, it wasn't so much the 64 cubic inch per minute metal removal rate (MRR) that impressed Novasel and other witnesses. Rather, it was the fact that such a large face mill could achieve this rate in such demanding conditions. The application required not just facing, but also contouring, all with extensions as long as 14 inches.
