 Polishing for Mirror-Finish Surface Accuracy


                    Mirror-finish accuracy

We provide polishing to remove residues, restore surface profile, and achieve the exact finish required before or after coating and repair work.

What Is Polishing?

Polishing is a precision surface finishing process essential for the repair and restoration of rotors and other cylindrical components. This service plays a dual role  used both before and after surface repair technologies are applied  to ensure optimal surface integrity, profile accuracy, and final appearance.

In the initial stages, polishing is employed to remove residual carbide or chrome layers left behind after decarbiding or dechroming. Flexible grinding belts of varying grit levels are used to clean the surface and restore curvature affected by prior welding procedures.

After coating, polishing ensures that the component meets tight dimensional tolerances and achieves a smooth, refined finish. Final polishing is performed using flexible diamond belts, leaving the component with a bright, smooth, and high-precision surface.

Why Choose Our Polishing Services?

  • Pre-Coating Surface Prep – Removes tough carbide/chrome remnants for better coating adhesion
  • Profile Restoration – Restores curved external surfaces altered during welding
  • Post-Coating Finish – Achieves required outer diameter based on customer specifications
  • Smooth & Shiny Result – Flexible diamond belts deliver high-gloss, professional finishes
  • Precision-Centered – Ensures accurate and consistent finishes for critical rotor applications
