The growth of the woodworking industry is increasing the demand for modern technological solutions for tools with an extended service life. One such solution is the NaDia protective coating.
The machining of solid wood is currently mainly conducted with carbide-tipped tools for hardwood or with high-speed steel with different tungsten content for softwood. Tools of this type have a shorter tool life compared to polycrystalline diamond (PCD), which for several reasons cannot be used in this type of machining. This results in more frequent tool changes and, in turn, longer machine downtime.
Understanding these problems, firm ITA TOOLS has prepared a range of coated tools for all manufacturers of wooden furniture, doors and windows.
What distinguishes NaDia's protective coating?
The NaDia protective coating is designed to work primarily in solid wood, both soft and hard. The coating of such tools is carried out using the DLC method. The process involves a thorough, step-by-step cleaning of the surface, followed by vacuum application of successive layers containing diamond particles. The main advantage of the NaDia coating is that it significantly extends the life of tools with HM and HSS blades. The diamond layer on the blades reduces the coefficient of friction to 0.003, which reduces material adhesion to the tool and significantly facilitates chip removal. These processes, in turn, have a significant effect on reducing heat build-up in the tool, resulting in extended tool life.
The thickness of the diamond coating is less than 1 micron, which does not dull the edge of the blade. The uncut blade runs smoother and leaves a very well finished edge.
Test protective coatings from ITA TOOLS
Coated tools already have a very large following, both in Poland and in Europe. Users note that their service life increases by up to four times compared to uncoated tools. Due to the coating's intended use for working in solid wood, the most commonly coated tools are a monolithic and planer knives spiral bits.
To get the most out of coated cutters, it is recommended that they be used in the thermo clamping chucks that can be found in the ITA TOOLS range. This is an excellent choice due to the elimination of the run-out problem, which directly affects tool life.
