Škoda Skoda SIU 250 Heavy-Duty CNC Lathe – 2500 mm x 9000 mm – Siemens metalldreiebenk

The Skoda SIU 250 stands as a titan in the field of heavy-capacity machining. This CNC-retrofitted lathe, currently located in the Czech Republic, is engineered specifically for the most demanding large-scale turning operations. By combining the legendary structural mass of the original Skoda casting with a modern Siemens Sinumerik 840D control unit, this machine offers the rare capability of handling workpieces up to 160,000 kg. With a massive 2500 mm turning diameter and a 9000 mm turning length, it represents a strategic asset for facilities managing oversized industrial components.
Who This Machine Is Suitable For
This lathe is designed for heavy-industry contractors and Tier 1 suppliers within the energy, shipbuilding, and large-scale mechanical engineering sectors. It is the definitive choice for enterprises that require extreme weight capacity and longitudinal precision for machining turbine shafts, ship propulsion components, or heavy-duty rolls. Companies looking to expand their heavy-machining capabilities without the decade-long ROI and extreme lead times of a new build will find the SIU 250 an unparalleled solution.
Key Advantages
– Extreme Load Capacity: Engineered to support and rotate workpieces weighing up to 160 tons, ensuring stability and safety during heavy material removal.
– Modernized Control Interface: The Siemens Sinumerik 840D integration provides contemporary CNC precision, complex programming capabilities, and high reliability.
– Substantial Working Envelope: A 9-meter turning length and 2.5-meter diameter allow for the processing of exceptionally rare and high-value components.
– Comprehensive Support Package: Included technical documentation, system backups, and a replacement blade head ensure operational continuity and ease of maintenance.
– Enhanced Stability: The SIU 250 is renowned for its rigid bed construction, which minimizes vibration and maintains geometric accuracy over long work cycles.
Compared to Common Alternatives
In the market for heavy-duty lathes, few modern machines can match the sheer mass and dampening characteristics of a classic Skoda frame. While newer, lighter CNC lathes may offer faster rapid speeds, they often lack the rigidity required for ultra-heavy workpieces exceeding 100 tons. Investing in this retrofitted SIU 250 provides the structural integrity of heavy-industry engineering at a fraction of the cost of a new machine, with the added benefit of a control system that is standard in modern machine shops globally.
Typical Applications
The Skoda SIU 250 is ideally suited for:
– Energy Sector: Large generator rotors and steam turbine shafts.
– Marine Engineering: Massive propeller shafts and engine crankshafts.
– Steel Industry: Heavy-duty rolling mill rolls and industrial cylinders.
– Defense & Aerospace: Large-scale structural housings and cylindrical components.
