Overview
The Hermle C 62 U is the flagship large-capacity 5-axis machining center in Hermle's High-Performance Line, designed for the largest aerospace structural parts, mold and die work, and energy sector components. With X/Y/Z travels of 1,200 x 1,300 x 900 mm (47.2 x 51.2 x 35.4 in) and a trunnion table rated for 2,500 kg (5,512 lb), the C 62 U operates at a scale that few 5-axis trunnion-table machines can match.
The Z-axis travel of 900 mm is a significant dimension — it provides the depth needed for deep-cavity mold work and tall aerospace structural components. The swiveling rotary table measures 1,350 x 1,100 mm with a collision circle of 1,400 mm (55.1 in) and vertical table clearance of 1,100 mm. Maximum workpiece diameter is 1,200 mm.
Spindle options include 9,000, 14,000, and 18,000 rpm on HSK-A63 with 29 kW (39 hp) continuous power. The torque-oriented spindle options reflect the heavy-duty roughing requirements at this machine scale. Rapid traverse is 50 m/min (1,969 ipm) on all linear axes.
Hermle's gantry-style column architecture maintains rigidity and thermal stability across the full working volume. The mineral-cast base weighs approximately 26,000 kg total. Positioning accuracy is +/- 0.005 mm with repeatability of +/- 0.003 mm. Control options include Heidenhain TNC 640 or Siemens 840D sl. The 60-tool standard magazine expands to 325 positions.
The C 62 U competes with the DMG Mori DMU 125/160 and Starrag Ecospeed series. New pricing runs $1,050,000-$1,550,000. This is the machine for shops that need the absolute largest Hermle platform with full 5-axis capability.

Strengths & Limitations
Strengths
- Largest Hermle 5-axis at 1,200 x 1,300 x 900 mm — handles true aerospace structural scale
- 900 mm Z-travel provides exceptional depth for deep-cavity mold and tall aerospace parts
- 2,500 kg table load accommodates heavy titanium and steel forgings
- 325-tool magazine option supports the most complex multi-operation programs
- Gantry column architecture maintains rigidity and accuracy across the full envelope
- 26,000 kg mineral-cast base delivers outstanding vibration damping at scale
Limitations
- Investment exceeds $1 million — justified only for large-part aerospace or energy applications
- 26,000 kg machine weight requires significant foundation engineering
- Hermle service network is smaller than DMG Mori or Mazak at this machine scale
- 50 m/min rapids are moderate for a machine of this size
