Walter has launched a major extension of its turning geometry program with new products that bring Walter precision and reliability to a range of new applications. Extensions include the FM4 positive inserts. Engineered for finishing stainless and high temperature alloys (ISO M, S), these inserts have excellent chipbreaking capabilities at low feed rates and low cutting depths. They are available in grades WSM10S, WSM20S and WSM30S.
Walter’s RM4 positive inserts are targeted at stainless and high-temperature alloys (ISO M, S) for roughing and medium machining operations. They are available in grades WSM10S, WSM20S, WSM30S and WMP20S.
The new FP6 positive inserts excel at finishing steels (ISO P) and provide superior chip control. They are available in grades WPP10S and WPP20S. The FP6 is a productive alternative to FP4 and MP4 and replaces PS5 in steel applications.
Walter’s FK6 positive inserts, available in grades WKK10S and WKK20S, are engineered specially for finish to medium machining. They are an alternative to MK4 and replace PS5 in iron applications.
Importantly, the Walter turning program extension also includes positive wiper inserts for PF and PM geometries. These inserts provide high surface quality and high feed rates. They also give users the flexibility of choosing to maintain their current surface quality with double the feed rate or 50 percent lower surface roughness with their current feed rate.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
Metal-removing edge on the face of a cutter that travels in a plane perpendicular to the axis. It is the edge that sweeps the machined surface. The flat should be as wide as the feed per revolution of the cutter. This allows any given insert to wipe the entire workpiece surface and impart a fine surface finish at a high feed rate.
The PCD inserts impart the finest surface finishes while shoulder, face and slot milling. The tools enable precise machining with reduced cutting forces and minimal vibration tendencies. They have a low cost because of their extremely long tool life as a result of the cutting edge being made of the…
WBH20C WL25 indexable inserts are full-radius copy turning inserts with Walter Lock positive engagement. The WL positive engagement provides maximum stability and precision for reliable machining of contours. With pocket support right under the cutting edge, and exceptional ability to prevent…
The MD344 Supreme and the MD340 Supreme three-flute versions both feature a 38° helix, while the MD340 Supreme four-flute has a 39°/41° variable helix, the MD340 five-flute version features a differential or unequal pitch.
A new type of flute design reliably evacuates chips, even with the tinniest drills. This capability ensures that hole depths up to 30 × Dc can be easily achieved with the DB133 Supreme micro drill with its 140° point angle. The DB131 Supreme micro pilot drill features a 150° point angle. Emulsion,…
To cover the widest possible range of applications, Walter offers the MP6 geometry in CCMT, DCMT, TCMT and VBMT basic shapes. Its short protective chamfer, which is characteristic of roughing inserts, ensures a high strength of cutting edge, even in challenging conditions, for example when…
TC388 Supreme (50–58 RC) and TC389 Supreme (55–65 RC) feature new patent-pending cutting geometries that fully shear off the root of the chip when reversing, thus torque peaks are minimized. This prevents fractures, prolongs the tool life, and increases process reliability. Furthermore, the new…
The 180°-point angle makes the DC118 Supreme ideal for plunging into inclined or round surfaces because the drill is guided quickly on the margins and centered accurately. At the same time, burr formation remains extremely low. The protective corner chamfer on the cutting edges protects against…
These WXN15 grade coated inserts are all introduced with a highly positive shaped geometry, which is particularly effective in machining ISO N materials. When used in advanced cutter bodies like the new Xtra·tec® XT M5468 button insert milling cutter, with G88 geometry, this also increases…
The system handles axial grooves from dia. 2.362-in (60 mm), cutting depths up to 1.299-in (33 mm), with insert width of 0.197-in (5 mm). The new system delivers maximum productivity and cutting parameters due to optimal cooling, strength and controlled chip breaking, along with high cost-…
The TC620 Supreme thread milling cutters utilize patent-pending Walter DeVibe technology with an anti-vibration land to effectively suppress vibrations and allow higher cutting parameters, while contributing to other TC620 Supreme advantages like a high level of process reliability and easy…
