Walter has introduced single-sided indexable inserts with new HU5 geometry. These HU5 inserts can dramatically boost productivity particularly in rough machining of stainless steels and heat-resistant superalloys and secondarily in steel. They are typically used in machining AISI 316 material, Inconel 718 and titanium.
The main cutting edge, which is protected by a negative chamfer, prevents insert fractures when machining hard scales and heat affected zones and thus optimizes insert performance in forged parts. Components with interrupted cuts and other demanding machining operations benefit as well.
Compared to double-sided negative inserts, HU5 has a large seating surface. This increases stability and permits greater cutting depths, feed rates, and metal-removal rates. In addition to the stable seating, the key factor in this improved productivity is the combination of HU5 geometry and Walter’s Tiger·tec Silver grades. This combination leads to increased tool life up to 75%.
With HU5 geometry, the curved cutting edge and deep chip groove produce low cutting forces even at high feed rates, reducing heat buildup. The variable rake angle at the corner radius allows for lower cutting forces and increases tool life. Available in grades WPP10S, WPP20S, WMP20S, WSM20S and WSM30S, the HU5 geometry rounds out the extensive Walter product range in the areas ISO S and M, leading to a total of 12 insert shapes in six grades.
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
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.
Because of the ground chip breaker on these inserts, the inserts are handed (left hand and right hand insert), but these are standard ISO shapes and sizes- so they are held in conventional ISO turning holders. The inserts also use ‘M’ or maximum material condition tolerance on the corner radii of…
Walter expanded the TC630 Supreme product range to include UNJC4 to UNJC9/16, UNJF4 to UNJF9/16 and MJ3 to MJ10 thread sizes. Optional internal coolant is available for thread sizes starting from MJ4, UNJF8 and UNJC8 to provide effective chip removal on deep threads.
The Paradur® Ti Plus taps are for threading blind holes with a geometry specially developed for machining titanium alloys with a tensile strength of at least 700 N/mm2 using emulsion instead of oil. The Prototex® TiNi Plus tap is effective for through-hole threading. Walter specially developed the…
The M5250 cutter is effective for milling steel, cast iron, stainless steel, aluminum and other non-ferrous metals (ISO P, K, M and N workpiece groups), as well as materials with difficult cutting properties. Unlike other full-effective helical milling cutters, the XTRA∙TEC® XT M5250 can also be…
The TC685 Supreme cutter is a left-hand cutting tool that features a 15° helix angle for excellent chip removal. Cooling with compressed air makes it possible to achieve maximum tool life in materials harder than 50 HRC. Additionally, internal coolant delivery is available for tools that create the…
MA230 Advance milling cutters adapt to most ISO materials and milling approaches. The extensive range includes options like corner radius, corner chamfers, reduced neck, and unequal helix. The helix pitch is meticulously aligned with the number of teeth, ensuring unmatched running smoothness. Your…
The MC166 Advance solid carbide milling cutter with increased core stability compared to a conventional tool core ensures a consistently reliable machining process even in unattended operations. A differential pitch provides optimum operational smoothness and significantly extends tool life.
The holders accept CCGT3xx, DCGT3xx and VCGT2xx indexable inserts and provide a high level of indexing accuracy even when turning parts with tight tolerance specifications. The short head dimension enables short clamping and high stability. The shank dimensions are 12 mm × 12 mm and 16 mm × 16 mm.
With the ability to cut blind-hole threads up to 3.5 × DN, the TC130 Supreme tap is targeted for applications in general mechanical engineering and the energy industry, such as for threading wind turbines. The tap is suitable for threading steel and cast iron (ISO P and K workpiece groups). Also,…
Both WKP01G and WPP05G grades are ideal for continuous cutting and occasional interrupted cuts in high tensile materials (approx. 280-410 HB or 130-200 ksi). Ideal applications include large-scale production of components for the automotive and energy industries, such as gearboxes, gears and rotor…
