Edge rounding

Fast & Repeatable Edge Rounding Solutions

Better coating performance starts at the edge

Sharp edges make it difficult for paint and protective coatings to achieve uniform thickness. As a result, these areas are often the first to suffer from premature corrosion.

Creating a controlled edge radius improves coating adhesion, increases durability and helps manufacturers meet demanding finishing standards.

N.KO Machines provide fast and repeatable edge rounding on steel components of various sizes and thicknesses.

Key benefits

Why manufacturers round edges before coating

Improved paint and coating adhesion

Faster edge preparation than manual grinding

Consistent edge radius on every part

Faster processing than manual deburring

Repeatable results across production batches

Why edge rounding matters

Improve coating coverage

Protective coatings naturally become thinner on sharp corners.

By rounding the edge before painting or galvanizing, manufacturers improve coating coverage and reduce the risk of corrosion-related failures throughout the product lifecycle.

Built for long-term durability

Edge rounding is particularly valuable for products exposed to outdoor environments, humidity or aggressive operating conditions.

A controlled radius helps ensure that protective coatings perform as intended and remain effective for years.
