The Skymach BR85 Large-Sized Slant Bed CNC Lathe (BR-85) is an industrial-grade, heavy-duty CNC turning machine engineered for heavy shaft processing, large flange turning, oilfield pipe components, valve bodies, power generation rotors, and heavy machinery parts. Engineered with a monolithic HT300 cast iron slant bed, an A2-11 integrated high-rigidity spindle unit with Φ106 mm through-bore, and a 22-30 kW high-output motor generating 580 N.m of torque, the BR85 provides maximum metal removal rates while preserving micron-level accuracy.
Heavy-Duty Structural Rigidity
- Monolithic HT300 Cast Iron Bed: The machine base is cast in one piece from premium HT300 high-strength cast iron, providing substantial anti-vibration damping and minimizing torsional deflection under heavy intermittent cuts.
- Integrated High-Rigidity Assembled Spindle: Built with premium double-row cylindrical roller bearings and high-precision angular contact thrust bearings, the A2-11 spindle withstands immense axial and radial cutting forces up to 2,000 RPM.
- Continuous Bar & Billet Capacity: Φ106 mm through-spindle hole supports bar feeding up to Φ90 mm, while front-end chucking accommodates 15-inch, 18-inch, or 21-inch hydraulic power chucks.
Extended Machining Envelope
- Multi-Length Center Distances: Available with center distances of 1,100 mm, 1,600 mm, 2,100 mm, 3,100 mm, 4,100 mm, and 5,100 mm (Z-axis travel up to 5,130 mm) to machine everything from short thick flanges to long ship shafts.
- 12-Station Heavy Tool Turret: Equipped with a Φ480 mm large-diameter turret disc accepting heavy 32 x 32 mm shank external turning tools and Φ50 mm inner boring bars, indexed seamlessly in just 0.5 seconds.
- Massive MT6 Programmable Tailstock: Massive Φ160 mm tailstock quill with MT#6 Morse taper and 180 mm travel firmly supports heavy workpieces weighing multiple tons.

Frequently Asked Questions
What is the warranty period for your machines?
We offer a standard 12-month warranty on all our CNC machines, covering the spindle assembly, ball screws, linear guides, CNC controller, and servo drive motors. Extended warranties and customized service plans are available upon request.
Do you provide overseas installation and training?
Yes. Our engineers are available for overseas dispatch to assist with machine installation, commissioning, and comprehensive operator training at your facility. Every machine also ships with English manuals, circuit diagrams, and video setup guides.
What is the typical lead time for an order?
Standard catalog machines ship within 30 days. Custom configurations — such as oversized spindle bores, extended bed lengths, or integrated 4th-axis rotary tables — typically ship within 60 days.
How do you handle spare parts requests?
We maintain a comprehensive inventory of standard spare parts. Genuine replacement components are dispatched via international express (DHL/FedEx) within 48 hours, ensuring minimal downtime for your production line.
