A2003828-280
HSK-A100 / BBT50 High-Torque & High-Speed Dual-Winding Spindle (220V)A2003828 | 305 N·m / 12,000 rpm | 280mm | Mitsubishi-Wound Motor | For HMCs & Gantry Mills
The A2003828 is a high-performance dual-winding electric spindle engineered for demanding applications on horizontal machining centers and gantry mills. Built with a robust 280mm housing and compatible with both HSK-A100 and BBT50 tool systems, it delivers exceptional versatility through its 220V, Mitsubishi-wound asynchronous motor. Operators can select high-torque mode (Y-connection: 305 N·m at 1500 rpm max) for heavy roughing, or switch to high-speed mode (Δ-connection: 12,000 rpm at 184 N·m) for productive milling and finishing. Designed for high rigidity, minimal thermal growth, and seamless integration with Mitsubishi drives via its native serial encoder, this spindle is a powerful upgrade for shops tackling large, challenging workpieces.
Technical Overview
This spindle is engineered to master both high-force and high-speed machining in one robust package. Its core strength lies in the specialized Mitsubishi-wound dual-coil design, which provides two distinct power curves optimized for different materials and...
