The Skymach BR52MY-550 Compensation Y-Axis Slant Bed CNC Turn-Mill Compound Lathe is built on a 30° monolithic HT300 cast iron slant bed equipped with compensation Y-axis travel (+58 mm / -58 mm), heavy-duty roller guideways (X/Y: 35 roller, Z: 45 roller), an A2-6 spindle (4,500 RPM, Φ52 mm bar capacity), and a BMT45 (15T) / BMT55 (12T) live tooling power turret. Engineered for high-efficiency multi-tasking, the BR52MY-550 combines turning, off-center milling, helical grooving, and tapping into a single automated cycle.
Comprehensive Machining Capabilities
- Compensation Y-Axis Flexibility: Full orthogonal Y-axis stroke up to 116 mm (+58/-58 mm) enables complex off-center pocket milling, radial drilling, and keyway slotting.
- Heavy Roller Guideway Rigidity: 35mm roller guides on X/Y and 45mm roller guides on Z axis provide exceptional dynamic stiffness and vibration damping.
- High-Speed A2-6 Spindle: 0 - 4,500 RPM spindle with 8YU timing belt drive delivers high torque at low speeds and fine surface finishing at high speeds.
Key Engineering Highlights
- Programmable Servo Tailstock: 500 mm travel servo-driven tailstock with MT4 center provides rigid, automated positioning for shaft machining.
- Ultra-Precise Motion: C3-grade preloaded ball screws and P4-grade bearings achieve repeat positioning accuracy of ±0.003 mm.
- HT300 Monolithic Cast Foundation: Dampens cutting harmonics and channels hot chips smoothly into the rear-discharge conveyor.

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.
