Flexible Polishing Head
The flexible polishing head is designed for complex surfaces such as screw thread raceways and cylindrical outer diameters. Used in conjunction with screw polishing machines, it is commonly applied in the super-finishing of ball screw raceways and the passivation of thread root fillets.

Features
- The flexible polishing head significantly reduces raceway surface roughness while providing controlled deburring and sharp edge passivation, which helps maintain lead accuracy and maximize rotational smoothness.
- To ensure a perfect fit, the polishing heads can be customized based on the rods provided by the customer. They utilize self-adaptive contouring to maintain constant contact pressure across various thread profiles, preventing geometry degradation in even the most delicate fine-pitch or non-standard screws.
