A2004451 Ultra-High-Power Machining Spindle
30 kW | 72 N·m | 170mm HSK-A63 | The Ultimate Heavy-Duty Solution for Gantry & Boring Mills
The A2004451 is a monumental electric spindle engineered to deliver uncompromising power and rigidity for the most demanding industrial machining applications. With a colossal 30 kW of power and 72 N·m of torque housed within a 170mm diameter body, it is purpose-built for heavy roughing, high-efficiency milling, and deep cavity work on large gantry machining centers, floor-type boring mills, and high-power vertical/horizontal machining centers. Featuring an HSK-A63 tool interface, a versatile design for both vertical and horizontal mounting, and an integrated 7 MPa through-spindle coolant system, it sets a new standard for productivity in machining high-strength alloys and large-scale components.
Technical Overview
This spindle represents the pinnacle of heavy-duty drive technology, designed to transform large machine tools into supremely productive assets. Its core philosophy integrates extreme cutting force with exceptional structural integrity and advanced thermal management. The 380V single-winding motor ensures broad compatibility with mainstream industrial drive systems, while its massive 900 N/µm radial stiffness provides the foundational stability required for precision under extreme loads.
Core Performance Advantages
- Unmatched Power & Torque: Delivers a transformative 30 kW of continuous power and 72 N·m of torque, enabling dramatically reduced cycle times for roughing and high-feed milling of hardened steels, titanium, Inconel, and heavy castings.
- Extreme Structural Rigidity: An exceptional radial stiffness of 900 N/µm and axial stiffness of 300 N/µm create an ultra-stable platform that virtually eliminates deflection and vibration, ensuring part accuracy and superior surface finish even during the most aggressive cuts.
- Advanced Integrated Cooling: A high-capacity spindle jacket cooling system (>10 L/min) works in concert with a high-pressure through-spindle coolant (7 MPa) to effectively manage heat at the source, enhancing tool life, enabling efficient deep-hole operations, and guaranteeing long-term thermal stability.
- Versatile & Robust Integration: The 380V single-winding design offers seamless compatibility with Siemens, Fanuc, and other third-party drives. Engineered for both vertical and horizontal installation, it provides maximum flexibility for machine builders and integrators.
- Heavy-Duty Reliability: A premium bearing configuration (71910×2 / 71914×4) and an extremely high drawbar force (18,000 ± 2,000 N) ensure secure tool clamping and deliver reliable, maintenance-free operation in continuous production environments.
