BALZERS, Liechtenstein, JuL 7, 2025 — Oerlikon Balzers, a technology brand from Oerlikon specializing in thin-film coatings for precision components and tools, is introducing BALDIA VARIA, a new advanced chemical vapor deposition (CVD) diamond coating engineered for cutting tools used to machine lightweight and ceramic materials. Supporting progressive wear behavior on a wide range of tool sizes and geometries, this coating responds to the growing demand for a more efficient machining of these special materials. By launching BALDIA VARIA, Oerlikon continues to expand its portfolio of high-performance diamond coatings while focusing on more sustainable and productive machining.
As the use of special materials such as fiber-reinforced plastics (CFRPs), composite stack materials, graphite, and advanced ceramics continues to grow – particularly in the aerospace, medical, and molding sectors – BALDIA VARIA helps improve part quality, increase tool utilization, and reduce manufacturing costs. The diamond coating is based on Oerlikon’s CVD plasma technology, resulting in a dense, nanocrystalline coating structure. This structural composition supports progressive wear behavior that enables early wear detection and optimized tool utilization – with the added advantage of an optimum cost-benefit ratio for tool management and production planning.
“With its extreme hardness and progressive wear behavior, BALDIA VARIA was developed with a clear goal: to help manufacturers machine special materials with greater reliability and cost-effectiveness,” says Matthieu Guillon, Product Manager for BALDIA Diamond Coatings at Oerlikon. “In addition, its adaptability across micro and large-scale tools, combined with our plasma-driven CVD technology, gives customers a diamond coating that extends tool service life, resulting in a lower total cost of ownership.”
A key advantage of BALDIA VARIA is its ability to deliver consistent coating quality across a wide range of tool geometries, from micro drills and inserts to large-diameter milling tools and saw blades. Particularly effective in roughing and finishing operations for CFRPs and ceramics, BALDIA VARIA’s progressive wear mechanism enables easier wear monitoring – helping prevent sudden tool failure and reduce unplanned downtime.
