C u ttin g: P rod u cts an d services Productivity gains Coated cutting tools can be used with substantially higher cutting speeds and feeds than uncoated tools. This reduces machining times and thus costs per piece. Longer tool life means fewer tool replacements and thus reduced setup costs. HSC and dry machining High-speed cutting and dry machining generate considerable heat. Thanks to the thermal stability, hot hardness and oxidation resistance of the coating, the heat is dissipated via the chip. Hard machining Hard and wear-resistant coatings make it possible to machine hardened steels up to 70 HRC. Tools with defined cutting edges allow the finishing of hard work- pieces, thus eliminating the need for grinding. Difficult to cut materials Titanium and nickel alloys as well as high-alloy steels are difficult to cut. Coatings with a low coefficient of friction and a low tendency of adhesion to the workpiece material make it easier to machine such materials. Re-coating offers even greater savings If resharpened tools are re-coated, they achieve the same performance as new coated tools and a longer total service life. Re-coating becomes a must if the service lives and cutting parameters prescribed for production lines are to be maintained. Partners for regrinding Regrinding and recoating must occur rapidly and efficiently. Oerlikon Balzers cooperates closely with reputable tool grinding specialists. Efficient logistics In most areas, Oerlikon Balzers offers a convenient pick-up service. Special transport containers eliminate the need to individually package the tools. Also, the order data can be transmitted digitally. BALINIT® reduces costs in cutting applications HQ016EN (1011) W e a re a t yo u r se rvic e . W o rld -w id e .

Precise values depend on the substrate, geometry, surface finish, and machining parameters. Form of wear Wear mechanisms Protection by coating Abrasion Hardness and high wear resistance Diffusion and abrasion Hardness, hot hardness, and oxidation resistance, low affinity to workpiece materials Thermal shocks due to temperature change Thermal resistance, protection against thermal overload Adhesion, welding-on of “sticky” substrates Oxidation resistance, good sliding properties, chemical stability, low affinity to workpiece materials Coatable materials Metallic materials such as high-speed steels, hot- and cold-working steels, stainless steels, heat-treatable steels, carbides and cermets can be coated. Heat treatment of tools The temperature in the final heat-treatment step (most commonly the tempering temperature in the case of steels) must be higher than the coating temperature. Surface conditions of tools Surfaces must be in the bright condition. Tools must not be chrome-plated, burnished, steam-tempered or bath-nitrided. Ground surfaces must not display grinding cracks, oxide films or rehardening burns. Cutting edges must not have burrs. Polished surfaces must be free of polishing residues. Surfaces must be free of rust, chips, wax, adhesive tape, and paint. Tools must be demagnetised. Brazed tools Brazed tools can be coated provided the filler metal has a melting point higher than 600°C and contains no cadmium. Packaging for shipment Tools are to be packaged in such a way that they will not be damaged by other objects or each other. The packaging has to be suitable for return shipment. On request, shipment can occur in coating fixtures. The use of transport grids for shank tools facilitates safe and cost-effective handling without the need for expensive individual packaging. Rust protection Tools should be coated lightly with water-displacing oil in order to safeguard them against rusting.
