Hybrid Sphere CNC Lathe

The SBL series includes rough turning, fine turning, carbide roller burnishing, part pulling, and the cut-off process.
The burnishing process is an ideal way to enhance the surface hardness, extend the lifetime and enlarge the allowance of abrasion.

The trajectory of B axis can be close to a ball shape. The result of roundness can be achieved to ± 0.0055mm, which will be better than a conventional lathe, X and Z axis running simultaneously.

Burnishing is the process of extruding the surface by pressure, which will not consume the material as grinding does. Instead of modifying the dimension of work piece, burnishing will re-rank the metal molecules to remove the machining trace so that the surface can be strengthened and enhanced 10% to 30%. The roughness can achieve to Ra 0.1~0.2 μm

The SBL series is the ideal solution for making the components of the steering system, such as Ball pin and Tie Rod for inner ball joint and outer ball joint, medical implements such as femoral head for hip joint , Piston head for piston pumps and etc...

The SBL series is designed for ball head machining, which is the best solution for high-quality sphere roundness and surface roughness.
