• Optimized for Swivel Head Integration: The 190mm housing with a dedicated flange and drive flat  ensures secure, accurate, and repeatable mounting within AC swivel head units, maintaining tool center point (TCP) accuracy critical for 5-axis work.
• Extreme Rigidity for Multi-Axis Stability: Ultra-high radial stiffness (900 N/µm) minimizes deflection and vibration during off-center and side-load machining operations, ensuring part accuracy and superior surface finish across complex contours.
• Effective Thermal & Chip Management: A high-flow cooling system (>10 L/min) manages spindle temperature, while the high-pressure through-spindle coolant (7 MPa) enhances chip evacuation in deep pockets and improves tool life, essential for uninterrupted 5-axis machining cycles.
• Robust Construction for Demanding Applications: Features a heavy-duty bearing system (71910×2 / 71914×3) and an extremely high drawbar force (18,000 ± 2,000 N) to guarantee tool security and reliable performance under heavy loads in any orientation.
