Machining spherical components remains one of the most demanding processes within the machinery sector. Ball valve spheres, articulated joints, spherical bearings and heavy-duty sealing fittings used in oil and gas facilities all demand dedicated turning machinery. Standard general-purpose lathes cannot maintain consistent spherical accuracy. For this reason, spherical lathes are essential production equipment for industrial manufacturers worldwide.
Dalian Haidi Machinery develops and manufactures two types of spherical turning machines to cover diverse production needs: compact CA6525 unit and heavy-duty CW6593B spherical lathe.
Introduction to Spherical Lathes & Industrial Applications
A spherical lathe is purpose-built turning machinery for creating internal and external spherical profiles, as well as shaft components fitted with spherical sections. Besides spherical turning operations, the machine supports drilling, reaming and other standard lathe work.
Typical application sectors:
- Manufacturing ball valves and industrial pipeline fittings
- Producing spherical bearings and articulated connectors
- Component production for energy, petroleum and natural gas industries
- Fabrication of hydraulic and pneumatic cylinder spare parts
CA6525 Compact Spherical Turning Lathe
Built on a well-proven general lathe platform, the CA6525 is engineered for spherical workpieces ranging between 50 mm and 380 mm diameter.
Key technical parameters of CA6525:
- Maximum swing over bed: 560 mm
- Max workpiece diameter above carriage: 280 mm
- Maximum workpiece length: 1000 mm
- Spherical processing range: 50–380 mm • Spindle through hole: 52 mm
- Spindle rotation: 24 forward speeds (10–1400 rpm), 12 reverse speeds (14–1580 rpm)
- Main drive motor: 7.5 kW • Machining precision grade: IT6–IT7
- Surface roughness: Ra 3.2 μm
- External dimensions: 2668 × 1130 × 1367 mm
- Machine weight: 2300 kg
The CA6525 is the ideal solution for manufacturers specializing in small-to-medium ball valves, spherical bearings and pipeline accessories.
CW6593B Heavy-Duty Spherical Lathe For Large Spheres
For large spherical workpieces with diameter up to 900 mm, the CW6593B heavy spherical lathe delivers outstanding performance within its product category.
Key technical parameters of CW6593B:
- Max swing over bed: 1430 mm
- Max outer spherical machining diameter over carriage: 900 mm
- Maximum workpiece length: 1500 mm
- Spindle bore: 104 mm
- Spindle taper: Metric 120 mm
- Spindle rotating speed: 18 grades, 5.4–720 rpm • Feed options: 64 longitudinal and cross feeds
- Rapid feed speed: 4000 mm/min
- Rotating worktable: 64 positioning angles, adjustable range 0.37′–89.3′
- Main motor power: 11 kW
- Machining accuracy: IT6–IT7
- Surface roughness: Ra 3.2 μm
- Overall size: 3360 × 1450 × 1950 mm
- Machine weight: 5500 kg
The integrated rotary table enables multi-angle processing of complex spherical workpieces, making this machine perfect for large-size valve production and energy equipment manufacturing.
Core Advantages of Haidi Spherical Lathes
