Understanding Ball Cages in Automotive Systems

What is a Ball Cage?

- Official Name: Constant Velocity Universal Joint (CV Joint)

- Key Function: Power transmission in vehicle drivetrains

- Critical Components:

- Bell housing

- Tripod bearing/steel balls

- Quality Control Focus:

- Spline dimensions

- Thread specifications

China's automotive industry has transformed from importing to independently producing critical components like constant velocity (CV) joints for over a decade.

More Superhard's engineering team has pioneered advanced precision forging technologies and manufacturing solutions, significantly reducing reliance on imported parts while improving production efficiency.

Precision Requirements for CV Joint Manufacturing

Ball cage grooves demand exceptional machining accuracy due to:

1. Tight component clearance tolerances (±0.003mm profile)

2. Strict surface finish specifications

3. Complex groove geometries

Moresuperhard's CBN ball cage milling cutter has the characteristics of simple structure, small size, light weight, high strength, and is not easy to collapse.

Therefore, its life is more stable than that of traditional milling cutters. It improves processing efficiency while ensuring the quality of the processed surface.
