Introduction
Haozhi Super Motor milling head DBDP-310-60/60-270/350-A26W-A/A is engineered for high-performance 5-axis machining. It combines exceptional rigidity, high torque density and precise motion control in a compact, lightweight assembly. Driven by advanced motor technology with a high-speed motorized spindle, it delivers superior cutting capability, micron-level positioning and fast dynamic response for complex metalworking tasks. Recommended for aerospace, automotive, mold & die and precision component manufacture to increase productivity, surface quality and machine performance.

Features

• High rigidity: Optimized bearing and spindle design provide axial and radial stiffness at the spindle nose exceeding 150 N/µm. A compact, fast-response clamping system with high locking rigidity ensures stable cutting conditions.
• High efficiency: Advanced motor technology achieves higher torque within the same installation envelope; C-axis rated torque 430 N·m (+15% vs. comparable products). Pneumatic A/C-axis clamping brake provides 1080 N·m (A) and 2160 N·m (C). Spindle max speed 20,000 rpm, continuous spindle torque (S1) 50 N·m and spindle power 40 kW to increase material removal rates and reduce cycle time.
• High precision: High-resolution encoder and torque motor ensure ±2 arcsec repeatability in 5-axis operations, minimizing lag-induced chatter and improving surface finish.
• Lightweight structure: Compact construction with a total machine weight of approx. 280 kg (≈4% lighter than similar products), reducing inertia and improving dynamic response.
