The next-generation Horizontal Center Nexus (HCN) 4000-III horizontal machining center from Mazak Corp. includes performance enhancements that provide increased productivity and cost effectiveness, especially when it is used as a go-to workhorse machine for high-volume part-processing operations. The enhancements include those that shorten part cycle times and allow the center to handle a wider variety of part sizes and more parts per setup. Faster rapid-traverse speeds and acceleration rates, shorter chip-to-chip times, and increased tool-size capability allow reduced cycle times. Greater part-size versatility and parts-per-fixture result from the center’s expanded Y-axis travel/stroke, as well as a higher allowable thrust in its Z axis. Rapid traverse speed is now 2362 ipm (60 m/min), and machine acceleration rate went from 0.8 to 1 g.
