Kitamura's Mycenter-HX250iF horizontal machining center offers a maximum workpiece size of 13.8 diameter × 15.7" H within a compact footprint for medium and long-run small parts machining requirements. The machine comes standard with a two-station automatic pallet changer, offering 1.8-second pallet change rotation with the freedom of a standard full fourth axis rotary table for multi-part tombstone fixturing. The machining center allows the user to machine multiple workpieces while another tombstone is being unloaded and reloaded with new parts to be machined. The standard 15,000-rpm spindle has fine finish capability and duel contact design. The duel contact design works in tandem with the high-speed spindle providing greater machining rigidity, improved surface finish, higher cutting accuracy and extended cutting tool life, the company says.
The Mycenter is equipped standard with high-speed rapids of 1,890 ipm on the X, Y and Z axes, a two-station 180-degree rotating pallet changer system and a 40-tool ATC is standard with a 1.2-tool tool change time. It is also capable of high-speed tapping at 6,000 rpm.
A full fourth-axis rotary table is a standard feature, allowing the user to machine complex, multi-sided parts without separate operations or special equipment. The table is capable of indexing at 0.7 second for 90 degrees rapid feed, enabling positioning at any angle very quickly, according to the company.
