Why Precision Grinding & Finishing?

Grinding and finishing are essential processes for achieving high surface quality, fine tolerances, and functional geometry in hard-to-machine metals. These processes allow:

  • Achieving extremely tight tolerances for aerospace and medical applications

  • Superior surface finish, reducing friction and wear in assemblies

  • Dimensional consistency, even on complex geometries

  • Preparation for coating, anodizing, or assembly

At EadeTech, we specialize in materials that are challenging to machine, where traditional cutting methods cannot meet surface or tolerance requirements.
