The copy milling cutters are tools with indexable cutting inserts with round cutting edges. It is either fully round cutting edge (indexable cutting inserts for toroid or ball nose milling cutters) or partially round cutting edge (from HFC milling cutters to radius versions of ADMX 11 and ADMX 16 indexable cutting inserts). The segment of copy milling cutters includes shell-type milling cutters, milling cutters with cylindrical clamping shank, Weldon-type chunk and modular (screw) milling cutters.
HFC (High Feed Cutting) milling cutters are getting ahead in the field of rough copy milling nowadays. Pramet offers 2 types of HFC milling cutters. The HFC milling cutters with ZDCW 12, ZDEW 09 andZDEW 07 inserts for feeds up to 3, 2 and 1 mm per a tooth. They are especially irreplaceable during machining with big protrusion of a milling cutter. At such operations they go beyond copy milling and are considerably more productive than face milling cutters. The tools are suitable for milling of soft as well as heat-treated steels and cast irons.
