In the manufacturing of diamond tools, innovative coating types are becoming increasingly important. Two standout methods are the dot coating and the honeycomb coating, distinguished by their unique surface structures and functional designs. These now form a permanent part of the portfolio at Diamantwerkzeuge Krauss.
They represent a significant enhancement of existing production techniques, reflected notably in the efficiency of grinding processes. Both coatings are universally applicable and suitable for all offered products—be it natural diamond, synthetic diamond, or CBN-based coatings.
This dot coating-method features a targeted arrangement of raised, rounded dots on the tool surface. The structure creates a pinpoint contact between tool and workpiece, significantly reducing friction. As a result, there is lower heat generation and reduced dust discharge during processing. The spaces between the dots enable efficient chip removal, ensuring cleaner and more precise machining. Dot coating is therefore ideal for applications requiring the highest precision and minimal material stress.
In contrast, honeycomb coating is based on a regular pattern of circular openings in the tool surface. This honeycomb-like structure ensures high cooling performance, as coolant can flow directly to the machining zone. The even load distribution across the surface also reduces diamond consumption, making this coating especially robust and beneficial for machine wear. This method is particularly suitable for demanding operations involving high material removal rates and thermal stress.
Both manufacturing methods offer substantial advancements in tool technology. While dot coating excels in precision and surface preservation, honeycomb coating provides a resilient, high-efficiency solution for demanding tasks. Depending on the application, these innovative structures enable targeted optimization of performance, tool lifespan, and machining quality.
