Tiger·tec Gold PVD Grade

August 27, 2022
Tiger·tec Gold® PVD Grade WSP45G for Milling and Drilling

Walter has introduced its Tiger·tec® Gold PVD grade WSP45G, a new generation of indexable carbide inserts for milling that dramatically expands capabilities for slotting, shoulder, and copy milling. The new grade can efficiently process demanding machining applications such as interrupted cuts and difficult materials.

This new grade is now capable of longer tool life, greater reliability, and approximately 30 percent greater performance in stainless steels (ISO M) and heat-resistant super alloys (ISO S), and up to 75 percent greater performance in steels (ISO P) than comparable grades. With the launch phase now complete, the PVD grade WSP45G Tiger·tec® Gold can be used universally in all standard Walter milling cutters.

The key to the grade's performance is its next generation coating technology and its special layer structure. The gold colored ZrN top layer facilitates exceptional low-friction characteristics as well as excellent wear detection, thus making it possible to utilize the full potential of the indexable insert to extend tool life. Next, multiple layers of aluminum oxide (Al2O3) increase the inserts temperature resistance.

All are applied on top of a TiAlN base layer and a premium carbide substrate as a foundation, greatly increasing the overall wear resistance. These properties make the new inserts ideal for challenging conditions, such as interrupted cuts, long overhangs with a tendency to vibrate, or for wet machining.

Related Glossary Terms

  • alloys

    alloys

    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • aluminum oxide

    aluminum oxide

    Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • indexable insert

    indexable insert

    Replaceable tool that clamps into a tool body, drill, mill or other cutter body designed to accommodate inserts. Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded. Some inserts can be resharpened.

  • milling

    milling

    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • physical vapor deposition ( PVD)

    physical vapor deposition ( PVD)

    Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.

  • slotting

    slotting

    Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.

  • stainless steels

    stainless steels

    Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.

  • titanium aluminum nitride ( TiAlN)

    titanium aluminum nitride ( TiAlN)

    Often used as a tool coating. AlTiN indicates the aluminum content is greater than the titanium. See coated tools.

  • wear resistance

    wear resistance

    Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
