CVD Diamond Cutting – the next generation of Diamond Cutting Tools

CVD Diamond Cutting

CVD” Thick Film CVD diamond. This outstanding new program of cutting tools from Becker has such extreme consistent hardness that its wear properties are anywhere from 2 to 10x that of PCD. This new diamond is grown in a chemical vapour deposition reactor in thicknesses of 0.5 mm-1.8mm which allows for a wide variety of milling tools and insert geometries. This pure diamond has no binders which allows extreme cutting edge sharpness giving you excellent surface finishes with virtually no cutting pressure. The absence of binders at the cutting edge allows for excellent thermal conductivity which reduces heat produced at the cutting zone. The extreme sharpness and the pure diamond cutting edge of the Becker “CVD” tools avoids chemical interactions with materials or cutting fluids which eliminates failures due to cutting edge erosion. This pure diamond maintains a sharper cutting edge far longer than that of the standard polycrystalline diamond tools. With this advancement in technology in cutting material, the technology to prepare the cutting tools has also evolved drastically. All of the “CVD” tips produced at Becker are adhered using a high vacuum brazing process that ensures excellent quality. Due to the extreme hardness, the cutting edge cannot be ground or eroded thus the Becker company has invested in High Tech lasers which not only prepare the cutting edges to the highest quality but also allows the 3D cutting edge geometries in various formations prepared in the same quality.
