SIGMA EKKON LEADER 6 VERTICAL MACHINING CENTER

Technical Description

The Sigma Leader 6 is a precision vertical machining center engineered for high-performance industrial applications. This three-axis CNC machine features substantial travel capabilities with an X-axis stroke of 1,600 mm (63 inches), Y-axis of 810 mm (31.89 inches), and Z-axis of 630 mm (24.8 inches), providing versatile workpiece positioning for complex machining operations. The machine is equipped with a powerful spindle system delivering 27 kW of motor power and achieving speeds up to 15,000 rpm, enabling aggressive material removal and precision finishing across diverse applications. The rigid cast-iron bed structure ensures exceptional stability and balance, minimizing deflection during cutting operations. The work table, measuring 1,750 mm × 770 mm, accommodates components weighing up to 2,000 kg, with a spindle taper of ISO 40 for tool compatibility. Control is managed by CNC systems such as Heidenhain ITNC530 or comparable platforms, offering modern programming capabilities including manual programming via USB and Ethernet connectivity. The machine incorporates rapid traverse rates reaching 50 m/min and features a high-capacity tool magazine with 40-position storage, facilitating efficient tool changes during production. The overall dimensions of 1,750 × 770 × 630 mm (L×W×H) with a machine weight of 2,000 kg reflect a compact yet robust design suitable for job shops, prototype facilities, and precision manufacturing environments. The Leader 6 is particularly valued in aerospace, automotive, medical device, and mold-making industries where precision and repeatability are critical. Its modular construction enables optional configurations including 4th-axis rotary tables for enhanced machining capabilities.
