Overview

The Hermle C 62 U is the flagship large-capacity 5-axis machining center in Hermle’s C-series lineup, designed for aerospace structural parts, large mold and die work, and energy sector components that exceed the envelope of the C 52 U. With X/Y/Z travels of 1,200 mm × 1,300 mm × 750 mm and a trunnion table rated to 2,500 kg, the C 62 U operates at a scale that few 5-axis trunnion-table machines can match.

Hermle’s gantry-style column architecture on the C 62 U maintains rigidity and thermal stability across the full working volume, critical when machining large aerospace structural components in titanium or aluminum where positioning errors accumulate over long tool paths. The modified gantry design positions the column directly above the working area, minimizing overhang and maintaining geometric accuracy at all A-axis positions from +30° to −130°.

The C 62 U ships standard with Hermle’s 18,000 rpm / HSK-A63 milling spindle rated at 29 kW continuous, with optional upgrades to 30,000 rpm for high-speed aluminum roughing common in aerospace structural machining. The 60-position tool magazine expands to 325 tools via Hermle’s chain-type extension module, supporting complex aerospace programs with large tool inventories. Rapid traverse of 60 m/min on X/Y and 55 m/min on Z keeps non-cut times manageable despite the large work envelope.

The C 62 U is automation-ready via Hermle’s RS 2 and RS 4 pallet handling systems, built for larger and heavier workpieces. The Hermle Automation Control System (HACS) manages multi-pallet production scheduling and integrates with shop-floor MES systems, enabling extended unmanned production runs on high-value aerospace and energy components.

Strengths & Limitations

Strengths

Largest working envelope in Hermle C-series at 1,200×1,300×750 mm — handles true aerospace structural scale
2,500 kg table load capacity accommodates heavy titanium and steel aerospace forgings
Gantry column architecture maintains rigidity and accuracy at all 5-axis positions across the full envelope
325-tool magazine option supports the most complex multi-operation aerospace and energy programs
Proven mineral-cast base (~26,000 kg total) delivers outstanding vibration damping for surface finish quality

Limitations

Investment exceeds $1 million — justified only for large-part aerospace, energy, or mold applications
Machine weight (~26,000 kg) requires significant foundation engineering and floor load capacity
Hermle’s North American service network is smaller than DMG Mori or Mazak at equivalent machine scale

Best For

Aerospace structural components: frames, bulkheads, and wing ribs in aluminum and titanium Large mold and die work requiring 5-axis contour machining of complex deep-cavity geometry Energy sector parts: turbine casings, large impeller bodies, and oversized valve bodies Defense components requiring high geometric accuracy across large workpiece footprints

Frequently Asked Questions

01 How does the Hermle C 62 U differ from the C 52 U?

The C 62 U offers a significantly larger work envelope (1,200×1,300×750 mm vs. 900×900×600 mm on the C 52 U) and a higher table load capacity (2,500 kg vs. 1,000 kg). The C 62 U targets large aerospace structural and energy sector parts that exceed the C 52 U’s capacity.

02 Is there a mill-turn version of the C 62 U?

Yes. The Hermle C 62 U MT adds integrated turning capability via a direct-drive torque motor on the C-axis, enabling turning operations up to 800 rpm alongside full 5-axis milling. It is priced approximately $200,000–$300,000 higher than the milling-only C 62 U.

03 What spindle options are available on the C 62 U?

The standard spindle is 18,000 rpm / 29 kW / HSK-A63, well-suited to titanium and steel aerospace work. An optional 30,000 rpm spindle is available for high-speed aluminum roughing and finishing common in large structural aerospace machining programs.

04 Can the Hermle C 62 U be automated?

Yes. The C 62 U is compatible with Hermle RS 2 and RS 4 pallet handling systems, sized for large and heavy workpieces. The Hermle Automation Control System (HACS) provides multi-pallet scheduling, tool life management, and MES connectivity for extended unmanned production.

05 What foundation requirements does the C 62 U need?

With a mineral-cast base and total machine weight of approximately 26,000 kg, the C 62 U requires a properly engineered reinforced concrete foundation meeting Hermle’s load and vibration isolation specifications. Foundation engineering consultation is recommended during the pre-installation phase.
