Abstract
The BT-40 Integral motor type milling spindle integrates a motor for enhanced performance and eliminates external power transmission constraints. This study optimizes spindle design through theoretical and FEA analysis of different bearing configurations. SOLIDWORKS models and ANSYS simulations assess deflection, stiffness, and natural frequencies. Bearing arrangement-1 with medium preload NSK bearings shows superior stiffness and operational stability, crucial for high-speed machining. This research emphasizes bearing selection's impact on spindle performance, guiding advancements in motorized spindle design for precision and longevity in industrial applications.
