Coatings for Machining Tools
Tool and Mold Making
Tools for Cutting Processes
Tools for machining high-quality components become precision tools with the highest service life and performance through coating with DIAFIN® chemical nickel dispersion layers.
Tools for machining non-ferrous metals, ceramics, and diamond are advantageously coated with DIAFIN® chemical nickel diamond layers.
For machining steel materials, the incorporation of cubic boron nitride has proven effective. CCT DIAFIN® dispersion layers combine the contour accuracy and high strength of the chemical nickel matrix with the high hardness of the embedded solid particles.
Coatings for Machining Tools
Machining tools for milling or grinding are manufactured with contours accurate to 1 µ and then coated with diamond or cBN particles. With DIAFIN D or cBN layers, the contours can be maintained within these exact tolerances, and the layer thickness is precisely defined according to the particle size. Applications include dressing tools for threads, gears, and gauges for these purposes.
Coating grinding tools is another application area for DIAFIN layers. Tools coated with DIAFIN layers can be reworked multiple times by stripping and recoating. This also allows wear on the base body to be compensated for by recoating with additional stock.
The Outstanding Properties of CCT Coatings:
- Contour-accurate coating even for geometrically complex components
- Compliance with the tightest layer thickness tolerances
- Homogeneous and reproducible solid particle incorporation
- Very good corrosion protection

Development
Development for Tool and Mold Making
Due to the geometries of cutting, finishing, and machining tools, physically manufactured tools, such as those produced by sintering, often cannot be used. DIAFIN coating systems can use defined grain sizes of diamond, or, when it comes to steel materials where carbon input would alter the substrate properties, cBN grain sizes as well.
The layers can be applied precisely to the micron in any thickness and also offer the possibility of reworking. Our experience is available to customers for their projects.
