Walter has introduced the Walter Tiger·tec Silver WPP05S, an extremely wear resistant indexable insert grade that delivers high performance and maximum productivity in steel machining (ISO P), particularly in roughing forged components and long production runs. This is made possible, in part, by the insert's thicker Tiger·tec Silver coating with its optimized aluminum oxide microstructure, and its post-coating treatment that provides greater reliability, increased toughness and reduced downtime to chipping, especially in high-volume production.
Another key design enhancement to the WPP05S insert grade is a new substrate that delivers better resistance to plastic deformation. This is particularly important at higher cutting speeds required for increased productivity. In addition, a thicker cobalt-enriched zone yields greater toughness and process reliability.
Thanks to features like these, the new Walter Tiger·tec Silver WPP05S inserts, available in multiple geometries (MP3, MP5, RP5 and NRF), can reliably operate at high cutting speeds with greater metal removal rates. In addition, field tests have confirmed significantly increased tool life at high speeds.
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.
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.
The MC377 Advance, with protective chamfer, corner radii, and center cutting edge, can be used for chrome-nickel and steel materials, as well as titanium. The MD377 Supreme is a solid carbide milling cutter with a corner radius and central internal coolant engineered for titanium machining.
The MC128 Advance boasts a wide diameter range of 1/4 -3/4 in. (2-25 mm) with a TiAIN coating for universal use. WJ30TF grade is available for ISO materials P, M, K, and S. The MC128 Advance is well suited for die and mold work as well as general metalworking. The MD128 Supreme provides 64% more…
With this new tool, V or D-style inserts with just two cutting edges and lower stability (ISO VBMT, VCMT, DCMT) are replaced with triangular cutting inserts with three cutting edges and high stability. These three-edged inserts allow for a 50° undercut angle, ideal for profiling operations. Since…
The Walter MD838 Supreme (conical version) has an effective radius of 250-1000 mm, a corner radius of 0.5 - 4.0 mm and is available in diameters of 6-16 mm. Walter also offers a version of this tool with ConeFit exchangeable head. The MD839 Supreme (tangential version) has an effective radius of…
High tool life is achieved thru WEP10C coated cermet grade with multilayer TiCN TiAlN PVD coating and fine cermet micro grain. The combination of edge preparation and grade also ensures dimensional stability over long periods of time, which boosts productivity in mass production
The unique TiAlN-Al2O3 multilayer coating system makes the WSP45G both hard and tough, and thus extremely resistant to abrasive wear and high temperatures, with controlled residual stresses and less flank wear, all boosting tool life. A special mechanical post-treatment improves hairline crack…
Enhancements to the Xtra·tec XT M5130 milling cutter, including a new clearance angle of 7° have added to this universal tool's existing benefits of high performance, high surface quality, exceptional reliability and safety, and outstanding versatility. The M5130 handles a wide array of…
Accure·tec adaptors are ideally suited for the Walter Xtra·Tec® XT milling cutter range. This makes the system highly versatile. For example, for components with deep cavities in aircraft construction and aerospace industry in general, as well as the automotive, energy, die/mold, and general…
The Xtra·tec XT M5012 is highly cost-effective thanks to inserts being offered in a fully ground configuration for maximum precision, or fully sintered configuration for maximum cost efficiency. The bodies are offered in either ScrewFit or shell mount and with two pitches for different applications.
The M5137 Xtra·tec® XT boasts reduced process costs thanks to its Tiger·tec® coating and six cutting edges per indexable insert. This translates to simple tool selection and low cutting material costs, and highly cost-effective operation due to low unit costs.
