Leo da vinci group provides a range of extreme performance products and solutions to meet our customer’s metal machining and processing requirements, including single crystal lab grown diamond, polycrystalline diamond and tungsten carbide products. Our products offer solutions across the range of metalworking tools and dresser applications, and their advantages variously include their ease of use in tool making, uniform wear, excellent thermal stability, choice of orientations (for single crystal lab grown diamond solutions) and that materials can be custom-engineered.
Single Crystal Lab Grown Diamonds for use in Metal Machining and Processing
Polycrystalline diamond (PCD) :
PCD is the first choice tooling material for non-ferrous abrasive metalwork materials, such as aluminium silicon alloys and metal-matrix composites. Providing the ultimate wear resistance, PCD ensures unparalleled part quality over long production runs and minimises machine down-time. We offers the widest range of PCD grade, catering for applications where the primary requirement is abrasion resistance, to applications where edge toughness is paramount.
Single crystal lab grown diamond solutions :
Our group single crystal lab grown diamond solutions are developed for wheel dressing and metalworking tool applications and give the toolmaker greater options for their tooling solutions. The overall benefits offered by single crystal lab grown diamond include high abrasion resistance for all types of dressing and cutting applications, high purity, high thermal conductivity and good thermal stability. We offer world class large single crystal lab grown diamond plates for the ultra-precision machining of metals, polymers and optical materials. Our portfolio of high-pressure synthesised and CVD-synthesised sizes minimise processing times and provide greater consistency compared to natural diamond. The advantages of single crystal lab grown diamond plates for tool making include ease-of-use, uniform wear, choice of 2pt and 4pt orientations, excellent thermal stability and materials which can be engineered to specified dimensions
Polycrystalline cubic boron nitride (PCBN) :
Our group polycrystalline cubic boron nitride (PCBN) composites are used for the production of precision cutting tools for machining ferrous materials such as hard steels, grey and hard cast irons and high-temperature superalloys. Different grades of PCBN are offered to meet specific application requirements. Low-CBN materials are most commonly used for the finishing of hardened steel components in the automotive industry, and superalloys for land and air turbine engine components. High-CBN materials are used for rough and finish machining of cast irons, and for extremely abrasive powder metallurgy parts, such as automotive valve seats
