Walter has added Walter Capto toolholders and insert widths to its Walter Cut MX grooving system. Capto toolholders feature enhanced rigidity and modularity, while the tapered polygonal shape handles both torsional and bending forces with ease. This interface can be used for lathes and turn/mill centers.
With the new Walter Capto monoblock tools (C3–C6), the MX system can now also be used on machines with Capto interfaces. In addition, new parting blades are introduced to work with automatic lathes and multiple-spindle machines. Walter has completed the range with new grooving inserts and toolholders for larger insert widths. Where previously only 0.031 in. (0.80 mm) to a maximum of 0.128 in. (3.25 mm) were possible, the insert width now ranges up to 0.222 in. (5.65 mm)—including the very common dimensions of 0.125 in. (3.18. 0.157 in (4 mm) and 0.196 (5 mm). Maximum cutting depth is 0.24 in. (6 mm).
These extensions are intended to make new applications possible for users of the MX grooving system, from small-parts production where a high degree of precision is needed; to job shops, where the focus is on fast, precise tool changes and cost efficiency.
The Walter Cut MX grooving system uses dowel pin location to prevent improper assembly of inserts into the holders. The dowel pin location along with the horizontal seating surface also provides high positioning accuracy and diameter repeatability for the inserts; thus, eliminating the need for “test cuts” after every cutting edge of insert change. With a unique design, the four-edge indexable inserts can be used even after one or more cutting edge breaks for maximum cost efficiency. The inserts also have a very long tool life thanks to the Walter-specific precision cooling and the Tiger·tec Silver grades.
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.
When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.
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.
