Product Description

Coating can make the service life of cutting tools increase 3-8 times and the speed of cutting is 20%-50% up. It is the technology to deposit the 2-18μm superhard films on the tungsten carbide cutting tools via PVD or CVD, finally to form complex structure of “tungsten carbide-transition layer-functional coating”. The hardness of coating cutting tools can reach to HV3000 (the hardness of tungsten carbide cutting tools is around HV1400-1800). In the same time, coating can improve the wear-resistance and hot resistance of tungsten carbide cutting tools.

Features of Tungsten Carbide Cutting Tools With Coating

  • Superior Thermal Stability: Advanced coatings such as TiAlN, AlTiN, or AlCrN act as a thermal barrier, allowing the tool to maintain its hardness at temperatures exceeding 900°C.
  • Enhanced Wear Resistance: The coating provides a surface hardness significantly higher than raw carbide, reducing flank and crater wear by up to 300-500%.
  • Optimized Chip Evacuation: A low coefficient of friction prevents “chip welding” (Built-up Edge), ensuring smoother chip flow and reducing the risk of catastrophic tool failure.
  • High-Speed Capability: Designed for High-Speed Machining (HSM) and dry cutting environments, reducing cycle times and eliminating the need for expensive coolants in specific applications.

FAQs

A1: PVD (Physical Vapor Deposition): Offers a thinner, sharper edge (2-5 um). Ideal for milling, threading, and finishing applications where precision is paramount. CVD (Chemical Vapor Deposition): Provides a thicker, more wear-resistant layer (5-20 um). Best suited for high-speed continuous turning of steel and cast iron.

A2: Specifically, our AlTiN-coated tools are designed for dry cutting. The aluminum in the coating forms a protective aluminum oxide layer under heat, which acts as a solid lubricant and heat shield.

A3: Nano-layered coatings consist of hundreds of alternating layers that stop micro-cracks from propagating through the coating. This significantly increases toughness compared to traditional single-layer coatings.
