Tailored Solutions for Composite Material Applications

COMPOSITES

Composite materials combine low weight with high strength – but they are challenging to grind and finish. Glass, carbon and aramid fibres embedded in resin can cause rapid wear of conventional abrasives, fibre pull-out, delamination and uneven surfaces.

KGS DIAMOND develops dedicated diamond tools for these demands. Our flap discs, grinding discs, belts, spiral bands, orbital discs and hand tools are designed to remove material efficiently while maintaining edge quality, laminate integrity and consistent surface finishes. For OEMs, component manufacturers and repair workshops, this means more control, predictable tool life and fewer rework steps in demanding composite applications.

Tailored to high-tech composites

Composite components in rail, marine, aerospace and wind energy require precise finishing of complex shapes and large surfaces. KGS DIAMOND tools are engineered specifically for fibre-reinforced plastics, combining controlled cutting action with reduced heat and vibration. This helps to limit fibre damage and delamination while achieving repeatable, high-quality surfaces on structural and cosmetic parts.

From fast stock removal to fine finishing

KGS offers solutions for every step in the composite finishing process: from aggressive grinding of mould parting lines and flash, through shaping and fairing, to fine finishing ready for coating or bonding. Our diamond tools allow operators to remove more material faster while leaving a clean, uniform surface that requires minimal rework.

Tools for complex geometries

Many composite parts feature inside radii, profiles and hard-to-reach areas. KGS diamond belts and spiral bands for rubber drums, as well as orbital discs, sheets and handpads, give operators the flexibility to work on curved surfaces, edges, cut-outs and repairs with precision and control.

Support for production and repair

Whether you manufacture composite structures or perform maintenance and repair, KGS works with your team to select suitable tools, grits and formats for your processes. Our specialists help match tools to machine types, materials and finish requirements, supporting stable production and efficient repair operations in demanding composite applications.

Applications

KGS DIAMOND solutions are used throughout the composite lifecycle – from production to repair. Typical applications include trimming and finishing moulded edges, removing flash and parting lines, fairing and smoothing wind turbine blades, preparing hulls and decks in boat building, finishing interior and exterior panels for trains and commercial vehicles, and refining structural components prior to painting or bonding.

Our tools support operations on flat and curved surfaces, inside radii, cut-outs and complex geometries. They can be used on manual angle grinders, orbital sanders, rubber drum systems and hand tools, helping operators achieve consistent, high-quality finishes on fibre-reinforced plastics and other advanced composite materials.
