The Skymach BR85DY Large-Sized Slant Bed CNC Turning Center with Y-Axis (BR-85DY) represents the pinnacle of multi-tasking heavy machining performance. Engineered with an orthogonal Y-axis (150 mm / ±75 mm stroke) and a 12-station BMT65 live tooling power turret driven by a 5.5 kW high-torque servo motor, the BR85DY transforms complex, multi-stage production into efficient single-setup manufacturing.
Orthogonal Y-Axis Multi-Tasking Architecture
- True Orthogonal Y-Axis: 150 mm (±75 mm) travel with 16 m/min rapid traverse allows precise off-center machining, keyway milling, helical milling, and off-axis hole drilling without geometric interpolation error.
- Single-Clamping Complete Machining: Combines heavy rough turning, precision contouring, multi-axis milling, drilling, and rigid tapping in one setup, drastically shortening delivery cycles and guaranteeing tight geometric tolerances.
- BMT65 Power Turret: Heavy BMT65 tooling interface ensures high structural rigidity and vibration-free torque transmission up to 5.5 kW with ER40 collet holders.
Heavy-Duty Base & Spindle Power
- Monolithic HT300 Iron Slant Bed: High dynamic mass and thermal stability ensure maximum vibration absorption during simultaneous turning and milling.
- A2-11 Spindle with 580 N.m Torque: High-rigidity spindle unit withstands massive cutting forces from both turning tools and live cutters, supporting speeds up to 2,000 RPM.
- Extended Center Distances: Tailored bed lengths up to 5,100 mm center distance with heavy MT6 tailstock for handling large oilfield mandrels, mining drill shafts, and turbine components.
