With a new seven-flute, eccentric relief (ER) design, the newest addition to the WIDIA VariMill family, the VariMill III ER solid-carbide end mill, is engineered for higher metal removal, longer tool life, and improved surface finishes in demanding workpiece materials such as titaniums and stainless steels.

VariMill III ER is true finishing endmill for higher metal removal rates, longer tool life, and improved surface finishes in demanding workpiece materials such as titaniums and stainless steels.

“This also means VariMill III ER customers can use high-speed machining techniques such as peel milling or trochoidal machining in high-strength alloys,” West adds.

Moreover, VariMill solid-carbide end mills are available through NOVO, WIDIA’s digital process knowledge application. With powerful process knowledge available on iPad and other digital devices, NOVO helps users define machining features, such as ramping or slotting in specific work materials, and then immediately reduces the product set to those like VariMill that can do the job. This provides far more useful process knowledge than any online catalog alone, all obtained in a fraction of the time.

BIG KAISER has introduced a new set of insert grades for its indexable tools—C-Cutter Mini, C-Centering Cutter and Fullcut Mill. The new inserts are optimized to extend tool life in stainless steel or aluminum.

“OEMs and tier suppliers in the aerospace and energy segments who regularly face working in high-strength, low-weight titaniums and stainless steels will want to see how the VariMill III ER together with the new WIDIA Victory Grade WS15PE can improve performance,” says Ron West, WIDIA product manager.

The Fullcut Mill is now available with the PVD-coated carbide ACP300 with nanometer-level thickness and ultra-multilayered TiAIN and AICrN film, replacing the ACZ350S for general steel applications. The new ACM300F is designed specifically for stainless steel work. The ACM300F boasts fracture and welding resistance and has demonstrated a lifespan 1.5x of conventional inserts in testing.

A newly developed coating and proprietary pre- and post-coat treatment significantly improves cutting edge consistency. Consistent cutting edges mean higher metal-removal rates, longer tool life, and improved workpiece surface finishes in expensive demanding materials. The tool is designed to be a true finishing endmill with the ability to take up to 30% radial engagement.

Demanding markets such as aerospace and energy are defined by the need for increased efficiency. In response, WIDIA is offering the VariMill III ER in a full line of options,including two, three, and five times diameter length-of-cut and all common aerospace radii and chamfered corners, metric and inch. With more and more additive layer manufacturing in the aerospace field, the trend going forward will be from roughing to semi-finishing and finishing operations, perfect for the increased efficiencies VariMill III ER provides. VariMill III ER end mills also come standard with the SAFE-LOCK option by Haimer, eliminating pull-out risk, and making the tool assembly more stable and concentric, which in turn increases surface finish and tool life.

The DS20 for aluminum/non-ferrous metals is available for the first time for the C-Centering Cutter. Its diamond-like DLC coating is ultra-smooth with a low wear coefficient and superior welding resistance, and effectively prevents burrs.

Steel (ISO P) is a complex material and it’s only getting more complex. In a competitive market it is essential to keep progressing and find ways that can make your steel turning operations more efficient and productive.

The new ACM250F stainless steel grade can be used for chamfering and spot drilling with the C-Cutter Mini or C-Centering Cutter. PVD-coated carbide with excellent smoothness, the new grade resists welding and chipping due to the ultra-multilayered thin film structure made of AlTiN and TiAlCrN. The ACM250F replaces the ACZ150 used with the C-Centering Cutter.
