CA6525 Spherical Turning Lathe: Mastering Outer and Inner Spheres with Precision

In industries demanding exact spherical surfaces—such as ball valves, optical parts, and precision mechanical joints—the CA6525 spherical turning lathe is engineered to deliver. With its capability to machine both outer and internal spheres, shaft-mounted ball elements, and hybrid curved surfaces, it offers a specialized solution where conventional lathes fall short.

Core Capabilities & Unique Features

• Swing over bed: Φ560 mm

• Max turning ball diameter: 330 mm

• Workpiece length: 1000 mm

• Spindle bore: Φ52 mm

• Spindle speed range: 10–1400 rpm (24 steps)

These specifications allow the CA6525 to handle a broad range of spherical workpieces, from small ball valves to spherical housings and shafts with embedded spheres.

Precision & Surface Quality
The CA6525 is built to deliver high accuracy—right up to IT6–IT7 class—with surface finishes typically in the range of Ra 3.2 μm or better.海迪机械+1 For optical or valve sphere surfaces, this level of finish ensures sealing performance and reliable mating fits.

Motion Systems & Feed Control

• Longitudinal feed options: 64 kinds

• Tool traverse speed: up to ~4 m/min

• Circumferential feed (normal): 0.37–5.58 rpm

• Fine circumferential feed: 0.25–0.46 rpm

• Coarse feed: ~5.94–8.93 rpm

This wide range of feed control allows both heavy profiling and delicate finishing on spherical contours.

Construction & Rigidity
The bed body is made of high-grade gray cast iron, processed via resin sand casting and cured for stability. The guide rail system typically employs a dual rectangular guide rail arrangement, ground and quenched for wear resistance. These structural measures reduce deflection and maintain accuracy during deep cuts and long runs.

Applications & Use Cases
The CA6525 is especially suited for:

• Ball valve spheres (outer & inner)

• Shaft-mounted spherical joints (e.g. ball heads, end rods)

• Optical mirror spherical surfaces

• Precision spherical housings for mechanical systems

With its focus on sphere machining, it outperforms general lathes when strict geometric and surface tolerances are demanded.

Conclusion & Call-to-Action
The CA6525 spherical turning lathe is an advanced, specialized tool for manufacturers needing excellence in spherical machining. Its combination of geometry capability, precision, and feed flexibility make it a competitive choice for demanding applications.
