WEZ - The new standard in 90° shoulder milling

With the new WEZ SEC Wavemill Series Sumitomo has combined the good results of many innovations of the last years in one milling tool. The result is a milling cutter that is very versatile and can be used for almost all milling tasks.

Whether you want face milling, shoulder milling, trimming, full slot milling, bore widening, angular plunging, circular milling or plunge milling, the new WEZ milling cutter from Sumitomo is your first choice, the WEZ milling cutter can shoulder all tasks.

But that's not all: there is also a new, universally applicable carbide grade ACU2500 for indexable inserts, which covers an unusually wide range of applications. It is suitable for machining steels and stainless steel as well as cast iron. The basis for this is, as is now standard with the modern indexable inserts from Sumitomo, the newly developed Absotech® Platinum coating technology. These multilayer coatings are characterized by extremely good layer adhesion and high heat resistance. This is the basis for long tool life and versatile application.

Sumitomo's WEZ milling cutters are available both as shell end mills and end mills. The cutter diameters range from 14 mm to 160 mm. The series includes two inserts of different sizes, so that various working areas can be better covered. In addition, matched to the desired diameters of the WEZ milling cutters, separate cutting edge geometries are available.

Although these milling cutters can be used universally, there are 6 different cutting edge designs and two different insert sizes to choose from in order to optimize the application to the respective task. The different cutting edges provide either high stability with heavily interrupted cuts or special accuracies for finishing applications, depending on the task. Type F inserts, for example, have sharp cutting edges that prevent burr formation and ensure even more precise squareness for all diameters.

Type P inserts also have sharper cutting edges. At the same time, however, the insert has been developed for even more precise shoulder angularity and produces right-angled milling surfaces comparable to results otherwise only achievable with solid carbide end mills.

A special feature is the shape S: In addition to a very sharp cutting edge, this insert type has a lapped rake face. This ensures that the chips slide off optimally and prevents the formation of built-up edges. In addition, this insert type is also available with a particularly adhesive-resistant DLC coating, which is particularly suitable for machining non-ferrous metals.

Those who choose the new WEZ milling cutter system from Sumitomo can choose between 10 different carbide and cermet grades, with and without coatings, which allows the universal tool to be optimally adapted to the material to be machined and the individual machining task.

The common feature of all WEZ milling cutters is the unusually soft cut with very low cutting forces. This not only reduces the noise level in the workshop, but also ensures lower energy consumption during machining. Older and weaker motorized machines can achieve previously unattained milling performance with WEZ cutters.

Depending on the type, the contact surfaces of the inserts are either sintered or ground with high accuracy, which gives these inserts a high precision insert seat and a stable contact and clamping. This provides high repeatability, improves axial run-out, avoids vibrations and enables very good surface qualities. The selection of ground cutting edges, which have also undergone special edge treatments, are not only designed for high cutting performance, but also ensure the stability of the inserts in tough everyday workshop conditions. In combination with the high-performance coatings, they ensure the unusual universality as well as the extremely long tool life of the new WEZ milling cutter series from Sumitomo.

It is fair to say that the universal WEZ milling cutter will become a "benchmark" in the workshops, against which the competition will have to measure itself in the future. The rapid sales success in the home country Japan already confirms this.
