The Starrag ZS 500-130 is a used five-axis machining center — sometimes referred to as a CNC machining center or horizontal machining center — a type of machine tool designed for precision multi-face metal cutting operations including milling, drilling, boring, and tapping, typically on complex workpieces that demand simultaneous multi-axis movement. Starrag is a Swiss machine tool manufacturer with a long-established reputation for high-precision machining solutions, supplying demanding industries such as aerospace, energy, transportation, and industrial components manufacturing.
This machine is equipped with a Siemens Sinumerik 840D CNC control system, one of the most widely used and respected controls in industrial machining, supporting simultaneous five-axis operation for complex contouring and part geometries. The single spindle is driven by a Step-Tec spindle unit and accepts tooling via an HSK-A 100 taper interface, reaching a maximum spindle speed of 12,000 rpm and delivering a maximum torque of 250 Nm, making it well suited to both roughing and finishing operations across a broad range of materials.
The machine features a 500 mm diameter rotary table with a resolution of 0.001° on the B axis, and an A axis that tilts across a 145° range (+35° / −110°), enabling highly flexible five-axis part positioning. Table speed reaches 30 rpm. The pallet system is the Staflex configuration, with four pallets in total, supporting continuous production by allowing workpiece setup away from the cutting zone.
The Y-axis transversal travel is 750 mm, and rapid traverse across all axes is 40 m/min, contributing to reduced non-cutting time. The tool magazine holds 60 tools, with a maximum tool diameter of 120 mm in standard pockets, expandable to 200 mm with adjacent pockets free. Maximum tool length is 400 mm and maximum individual tool weight is 15 kg, providing considerable flexibility in tooling selection.
The machine requires a three-phase 400 V / 50 Hz electrical supply and a compressed air connection at 5 bar. At approximately 22,000 kg, the machine is a substantial installation requiring appropriate foundations and handling equipment.
