Valenite adds high-velocity performance and precision accuracy to its lineup of milling cutters with the launch of VFlash for the high speed machining of aluminum alloys. Featuring a serrated, pocket design and direct-mount insert clamping system, the milling cutter offers safe, rigid and chatter-free operations at speeds as fast as 20,000 sfm—rates for optimal use of PCD inserts for aluminum applications and CBN tools for other  materials. According to the company, the milling cutter reduces premature tool wear, which minimizes unnecessary tool changes. Also, it provides high metal removal rates and improved surface finishes.   The high rigidity of the insert mount is characterized by a closed wedge-lock, pocket design where 75 percent of the insert body is protected and able to absorb high centrifugal forces. Overall system strength is enhanced by incorporating a serrated insert face and pocket surface to align and secure the insert. This decreases lateral shift during operation. Within the pocket, the hardened wedge lock is positioned at the insert underside, acting as a damper against vibrations and designed to protect the cutter body.   The direct-mount insert results in a more compact and durable clamping system than conventional-style mechanisms, and it permits a more aggressive pitch and higher insert density, the company says. This allows for greater feed and material removal rates. The clamp design also allows for quick change-over.   Sizes range from 2" through 12" in diameter. Cutters with metric diameters and mountings are also available, as well as special tools designed for specific applications.
