Adjustable Milling Cutters
A new family of high speed milling (HSM) adjustable end mills and face mills from Iscar are said to improve milling of aluminum, non-metallics, cast iron and hardened steel, especially in automotive and aerospace applications. The dynamically balanced cutters are designed to work with polycrystalline diamond (PCD) or cubic boron nitride (CBN) inserts, which provide cutting edge protection and quality surface finishes, the company says. They also accommodate standard HSM-rated Helido 2000 carbide inserts.

Optimal Milling Strategy For Entering Material From The Side
These animations show why an arc in the same direction as tool rotation is effective. The strategy is relevant for entering material from the edge, as well as for pocketing.

Video: 56-Percent Productivity Increase By Reducing Chatter
The video compares a milling pass that chatters to one that is stable. Because the stable speed permits greater depth of cut, productivity increases.

Side Turn-Milling Of A Massive Crankshaft
This video footage showing the machining of a massive crankshaft suggests some of the possibilities of turn-milling. Not all shops realize possibilities such as this even on their own smaller-scale turn-mill equipment.
WatchEnd Mills For Large-Volume Machining
Developed in conjunction with major aircraft builders, Emuge’s Alu-Jet-Cut solid carbide end mills are designed for rapid, large-volume aluminum machining in mold and die, aerospace, automotive and machine tool manufacturing applications. The company says the tools are particularly useful for machining monolithic airframe structural components, which often require removal of as much as 95 percent of the weight of a solid block of material. The end mills are capable of cutting speeds in excess of 3,000 sfm.

The Z-Plunge milling cutter from Kennametal is suited for aerospace, die and mold and general engineering applications. The cutter is designed to increase chip evacuation and productivity. Four cutting edges per insert offer good economy, the company says.

SGS Tool Company’s Z-Carb-AP variable rake end mill offers three stages of chatter suppression resulting in a quiet, stable milling operation. In stage one, unequal flute spacing disrupts the rhythmic pattern created by the cutting edge of common end mills. This suppresses the development of damaging harmonics.

Valenite has added the V560 heavy-duty, roughing face mill to its general purpose Penta family of five-sided, face milling cutters. The 0. 400" depth-of-cut capability allows for machining under the tough outer layer of forge or cast workpieces, reducing insert wear compared to smaller inserts, the company says.

A line of high-performance end mills for aluminum materials consists of two- and three-flute tools for roughing and finishing applications. This line, manufactured by Onsrud Cutter, also includes a selection of corner radii and neck and flute lengths. The large “sweet spot” of the tools allows for virtually chatter-free machining at high rpm and on heavy cuts.
