modern equipment review 14,000-rpm spindle provides 240 Nm of torque and 30 kW of output. Other spindle configurations are available, including a 14,000-rpm high-torque version and a 20,000-rpm model for faster speeds. T he machine c a n also be e quippe d with a 24,000-rpm high-per formance core-cooled spindle providing up to 80 kW of duty-rated (60 kW continuous) output. The HMC features a twin-direct-drive rotary table design with a three-point bed casting and tiered column structure for increased rigidity. It can accommodate workpieces measuring 600 × 385 mm (23.62" × 15.15"). The X-, Y- and Z-axis travels measure 730 × 730 × 680 mm (28.7" × 28.7" × 26.8"); linear acceleration is 1 G on the X and Y axes, and 0.8 G on the Z axis. A closed-loop thermal management system ensures reliability and accuracy by removing heat generated by the direct-drive rotary table motor s. A r ing-st y le ATC60 tool magazine is standard; matrix magazines with capacities of 133, 218 or 313 are available as options. A pallet changer enables part loading and unloading via a 45-degree pivot point that transfers pallets from a vertical to a horizontal orientation.
