Model A2002512 High-Torque Milling Spindle
Power Redefined: Engineered for Heavy-Duty Cutting and Maximum Stability
The A2002512 redefines the capability of a 100mm spindle, shifting the paradigm from pure speed to formidable force. Engineered as a powerhouse for demanding milling applications, it delivers a groundbreaking 3.8 Nm of rated torque—nearly double that of conventional high-speed models—making it the ultimate solution for heavy roughing, deep cavity milling, and stable machining of tough materials like steel, stainless steel, and alloys.
Technical Overview: The Power-First Philosophy
Built on a robust 380V single-winding, 4-pole asynchronous motor platform, the A2002512 is designed where cutting force matters most. By optimizing its performance for a potent lower speed range, it ensures exceptional power transmission, minimal vibration, and unparalleled process stability. This spindle is not an iteration; it’s a strategic engineering response to the need for relentless, chatter-free material removal.
Key Advancement Over High-Speed 100mm Spindles:
- Core Design: Ultra-High Torque vs. High Speed
- Critical Metric: 3.8 Nm Rated Torque (90% increase over comparable 100mm high-speed spindles)
- Operational Sweet Spot: 12,000 rpm Rated Speed for optimal power delivery
- Industrial Voltage: 380V for broader compatibility with standard workshop infrastructure
Core Performance Advantages
- Unmatched Cutting Force: With 3.8 Nm of continuous torque, it enables the use of larger diameter tools, deeper axial cuts, and higher feed rates, dramatically reducing cycle times for roughing and semi-finishing operations.
- Engineered for Stability: The combination of a lower operational speed range and a precision-matched bearing system (Front: 7007X2, Rear: 7006X2) guarantees extremely low vibration, protecting tool integrity and achieving superior surface finishes even under heavy loads.
- Robust & Reliable Power: The 380V motor provides efficient and consistent power, engineered for sustained performance in the most demanding industrial environments.
- Superior Thermal Management: A high-capacity liquid cooling system (flow >3 L/min) is essential to manage the thermal output of high-torque operation, ensuring long-term accuracy and durability.
- Configurable for Integration: Offered with your choice of ISO25 or HSK-E32 tool holder and multiple encoder feedback options (Sine Wave, Square Wave, Syntec-Compatible) for seamless fit into your CNC control system.
