Hermle C 250 GEN2

The Hermle C 250 GEN2 is the updated generation of Hermle's entry-level 5-axis machining center in the Performance Line, now shipping with the Heidenhain TNC7 control and refined spindle options. It retains the proven modified gantry architecture and mineral-cast bed that made the original C 250 a benchmark for compact 5-axis accuracy, while adding usability improvements and updated drive technology.

X/Y/Z travels remain 600 x 550 x 450 mm (23.6 x 21.7 x 17.7 in) with a swiveling rotary table providing +/- 115 degrees of A-axis tilt and 360-degree continuous C-axis rotation. The collision circle measures 770 mm (30.3 in) at the A-axis 0-degree position. Table load capacity is a generous 1,100 kg (2,425 lb), which is exceptional for a compact 5-axis platform and handles heavy fixtures and steel workpieces without compromise.

Spindle options on the GEN2 include 15,000, 16,000, and 20,000 rpm configurations on HSK-A63 tooling with 20 kW (27 hp) continuous power. The 16,000 rpm option is new to the GEN2 generation, offering a middle ground between the torque-oriented 15K and the speed-oriented 20K spindles. Rapid traverse is 35 m/min (1,378 ipm) on all linear axes.

The TNC7 control is a significant upgrade over the TNC 640, offering a modern touchscreen interface, improved 5-axis kinematic functions, and enhanced Dynamic Precision features for better contour accuracy during simultaneous machining. The mineral-cast base provides vibration damping 6-8x superior to cast iron, directly benefiting surface finish quality on mold and die work.

The C 250 GEN2 competes with the DMG Mori DMU 50 3rd Generation and Mazak Variaxis C-600 as an entry point into premium 5-axis machining. New pricing runs $280,000-$420,000 depending on spindle and options.
