Recently, Hartzell tested three advanced Mazak machine tools for incorporating into high-performance cells at the propeller manufacturing facility. Those machines were a Mazak Integrex e-420H-S full five-axis multitasking machine, the Integrex i-200ST multitasking machine, and a Quick Turn Nexus 400-II turning center.


On both Integrex machines, Hartzell opted for Capto C6 spindle interfaces as well as expanded tool capacities—80 on the Integrex-420 and 110 (split magazines with 55 each) for the Integrex i-200ST. The reason for these larger tool magazines is that the shop wants to set up tools and forget them. “We don’t want our machinists wasting time having to pull tools in and out of a machine,” Carter said. “Sometimes the tooling is redundant, but in most instances, it’s all differ- ent and pre-staged to handle families of parts within a cell.” One key family of parts that will benefit from Mazak’s advanced machine tool technology is the blades for propel- ler assemblies. Hartzell estimates that the Integrex e-420H-S
