Tools / Turning Tools / Overview of Turning Tools / Coated Cemented Carbide PVD

Physical Vapour Deposition (PVD) coatings on cemented carbide inserts enhance performance in precision machining tasks. These coatings are applied through a low-temperature process, which helps retain the toughness of the carbide substrate. PVD-coated tools are widely used in applications requiring sharp edges and high accuracy, especially in finishing operations and when machining difficult-to-cut materials.

Key Features

  • Thin, Hard Coating Layers: PVD coatings typically range from 1 to 5 micrometres in thickness, providing increased hardness and wear resistance without significantly changing the tool’s geometry.
  • Improved Edge Retention: The low deposition temperature preserves the sharpness of cutting edges, essential for fine finishing and tight tolerances.
  • Oxidation Resistance: PVD coatings help reduce thermal degradation, which is particularly useful in applications involving high-speed or dry cutting.
  • Versatility in Material Compatibility: Effective on a wide range of materials, including stainless steel, titanium alloys, and other difficult-to-machine metals.

Applications

  • Finishing and Semi-Finishing: PVD-coated carbide tools are commonly used for finishing operations where high surface quality is required.
  • Machining of Heat-Sensitive Materials: Useful for applications involving stainless steel, superalloys, and other workpieces that generate high cutting temperatures.
  • Interrupted Cutting: The combination of a tough substrate and hard coating provides durability in operations with variable loads or interrupted cuts, such as milling.
