Overview

The Hermle C 62 U MT is the mill-turn variant of Hermle's largest 5-axis platform, combining full simultaneous 5-axis milling with integrated turning capability on the C-axis table. This machine is built for shops that need to complete complex parts in a single setup — think aerospace structural components, landing gear fittings, or large energy sector parts that previously required separate milling and turning operations.

X/Y/Z travels are a generous 1,200 x 1,300 x 750 mm, with the trunnion table accommodating workpieces up to 2,500 kg. The C-axis table spins up to 800 rpm for turning operations, driven by a direct-drive torque motor for smooth surface finishes. The standard milling spindle runs at 18,000 rpm on HSK-A63 with 29 kW continuous power. Rapid traverse is 60 m/min on X and Y, 55 m/min on Z — considerably faster than the standard C 62 U.

The mineral-cast machine base weighs in at approximately 26,000 kg total, providing the mass and damping needed to handle both heavy milling and turning forces. The 60-position tool magazine is expandable to 325 tools for complex multi-operation parts. Control is Heidenhain TNC 640 or Siemens 840D sl, both with full mill-turn programming support. New pricing starts around $1,200,000 and climbs quickly with options.

Strengths & Limitations

Strengths

Complete 5-axis mill-turn in one setup eliminates multiple machines and fixture changes
2,500 kg table capacity handles the largest aerospace and energy sector workpieces
800 rpm C-axis turning with direct-drive torque motor delivers excellent surface finish
Massive mineral-cast base at 26,000 kg provides outstanding vibration damping
325-tool magazine option handles the most complex multi-operation programs
Modified gantry architecture maintains accuracy across the entire work envelope

Limitations

Price tag exceeds $1.2 million — this is a flagship investment
26,000 kg machine weight requires significant foundation engineering
Floor space requirements are substantial for the machine plus chip management
Hermle North American service network is smaller than DMG Mori or Mazak
Turning capability, while excellent, does not match dedicated heavy-duty lathes for pure turning work

Best For

Aerospace manufacturers producing large structural components requiring both milling and turning features Landing gear and engine case production needing done-in-one 5-axis mill-turn Energy sector turbine component manufacturing Large mold bases requiring combined milling and circular interpolation turning High-value contract shops seeking maximum process consolidation on premium parts

Frequently Asked Questions

01 What does a Hermle C 62 U MT cost?

New machines start around $1,200,000 and can exceed $1,800,000 fully loaded with high-speed spindle, maximum tool magazine, and automation. Used machines are rare on the secondary market.

02 How does the mill-turn capability work?

The C-axis trunnion table uses a direct-drive torque motor capable of 800 rpm for turning operations. The Heidenhain or Siemens control handles seamless switching between milling and turning modes within the same program.

03 What is the difference between the C 62 U and C 62 U MT?

The MT version adds turning capability via a high-speed direct-drive C-axis table motor (up to 800 rpm). The base machine geometry, travels, and accuracy specifications are shared between both variants.

04 Can it replace a dedicated lathe?

For parts that are primarily milled with some turning features, absolutely. For dedicated high-volume turning or parts requiring very high turning speeds, a purpose-built lathe is still the better choice.
