In the field of precision machining, spherical parts are among the most challenging to produce. Their geometry requires constant precision across multiple axes and smooth curvature that ordinary lathes cannot easily achieve. The CA6525 spherical turning lathe is designed to address this challenge - combining stability, versatility, and repeatability for outer and inner spherical machining.
The CA6525 adopts a horizontal bed structure, offering a maximum swing over bed of 560 mm and a turning ball diameter up to 330 mm. It can process spherical surfaces, hemispherical forms, and curved transitions on various materials such as steel, copper, and aluminum alloys. Whether for valve balls, optical lenses, or special mechanical couplings, it ensures both geometric accuracy and surface quality.
Technical Highlights
The CA6525 is equipped with a mechanical spherical cutting mechanism that allows the cutting tool to move along a precise arc path. The machine provides multiple feed rates, covering fine finishing and heavy-duty cutting requirements. Its spindle speed range of 10–1400 rpm (24 steps) offers flexibility for both soft and hard material processing.
The machine structure uses high-strength cast iron, stress-relieved through heat treatment, ensuring long-term rigidity and accuracy. Hardened and ground guideways minimize wear and maintain performance even after extended use.
Reliable Accuracy and Stability
Accuracy remains a core advantage of the CA6525. The machine achieves positioning precision within IT6–IT7 class and surface roughness up to Ra3.2 μm. Combined with a robust main spindle system and balanced rotation, this ensures reliable operation for high-demand production lines.
Applications in Modern Industry
The CA6525 plays a critical role in multiple industries:
Ball valve manufacturing - precise spherical sealing surfaces
Optical equipment - reflective and refractive curved components
Aerospace - mechanical spherical joints and bearing seats
Machinery parts - spherical housings and coupling balls
Its adaptability allows both single-piece machining and small-batch production, making it suitable for workshop, factory, and research applications alike.
Conclusion
With the continuous development of modern precision engineering, spherical machining requirements are becoming more refined. The CA6525 spherical turning lathe represents a balance between innovation, reliability, and cost-effectiveness - a powerful tool for manufacturers seeking to expand their machining capabilities.
