5-axis machining center S1250 HD

horizontalfor the aerospace industryfor titanium

Overview
The S1250 HD is predestined for simultaneous 5-axis heavy machining of titanium and Inconel parts due to its excellent static and dynamic properties. Hydrostatic guideways provide a significant performance advantage in titanium machining: increased rigidity and damping allow greater cutting depths and reduced roughing times while also improving finishing by limiting column pitching and enabling higher accelerations and faster five-axis movements.

Applications

• Titanium structural parts — unrivalled material removal rates of > 800 cm³/min in titanium
• Small landing gears — approx. 30% productivity gain for hard metals such as titanium or Inconel
• Titanium casings — up to 30% more productive for hard metals

World record / Performance
With Starrag Tools and Starrag Technologies, the S1250 HD achieved a material removal rate of 1,516 cm³/min on Ti6Al4V structural components, demonstrating benchmark performance in heavy-duty titanium machining.

Spindles
Starrag supplies extensive spindle know-how with over 2000 units delivered. For hard-to-cut materials Starrag spindle design increases material removal rates through:

• Short, sturdy spindle shafts for superior stiffness
• Compact build-up for improved collision contour and shorter tool overhangs
• Torque characteristics tuned for hard material machining

Machine design & sizes
The S1250 HD is the only machine in its size class equipped with hydrostatic guideways. A highly rigid structure combined with massive preloaded hydrostatic guides increases dynamics and roughing performance. Maximum workpiece capacity: 1000 x 1250 mm, up to 5000 kg. Compact, stiff milling heads allow the use of shorter tools for added stability.

Tool handling
The machine is fitted with Starrag tool magazines and changers, available up to 465 places per machine (HSK-A125). Chain and tower magazines offer:

• Fast, reliable operation validated in hundreds of machines
• Tool loading during machining
• Wide range of magazine sizes and configuration options

Precision and process capability
Engineered to deliver reliable production under variable conditions (e.g. fluctuating temperatures, minimal warm-up), reducing the need for frequent CMM checks and lowering energy requirements for thermal stabilization.

Additional information
High-performance simultaneous 5-axis machining center optimized for heavy-duty titanium and Inconel machining. Compact milling heads support higher stiffness and stability, increasing achievable material removal rates.
