Mazak Orbitec 20

The Mazak Orbitec 20 is a pallet machine with turning capability: the work sits on a 25 in (635 mm) × 25 in (635 mm) pallet, the spindle takes CAPTO C8 tooling from a 60-tool magazine, and Mazak's feature list gives it a 19 in diameter turning capability. The spindle runs to 600 rpm and is rated 30 kW (40 HP) on a 30 min. rating.

Those figures describe a machine for large, awkward components. The pallet accepts a workpiece of up to Ø41 in (1,041 mm) × 51 in (1,295 mm), far larger than the pallet itself, and Z travel is 48 in (1,219 mm). X travel is only 11 in (279 mm). Mazak attributes the turning capability to the headstock, which its feature list calls a unique design, and it describes the spindle motor as integrated. The table has no chuck or bar-capacity rows, so the part is fixtured on the pallet as it would be for milling.

Speed and power need reading with care. A 600 rpm ceiling suits the large diameters the machine is meant to turn and rules out small-tool, high-speed work. The 30 kW (40 HP) figure is a 30 min. rating; the table gives neither a continuous rating nor a torque figure, and both are worth requesting from Mazak before heavy cuts are planned.

Tool changing is automatic, and 60 tools is a large magazine for parts with many different features or for redundant tools on long cycles. Mazak lists a two-pallet changer as an option, together with integration into its PALLETECH system for linking with other Mazak machining centers in automated cells. The table gives no pallet load, machine weight or footprint, all of which matter for parts of this size.
