Sandvik Cormant's End Mills Eliminate Machining Chatter

Sandvik Coromant has expanded its line of CoroMill Dura solid end mills with aluminum-specific tools.

The standard assortment offers diameters from 2–25 mm, depths of cut between 1.5–3 × D, neck options, extended reach cutters and sharp and corner radius styles. Custom options include coated grades for more abrasive aluminums, specific diameters, corner designs and shank options.

Sandvik Coromant’s specialized WhisperKut helix concept — in which each flute is carefully oriented, unequally spaced from the others and has its own individually adapted helix angle — is designed to break up harmful harmonics and eliminate vibrations, resulting in silent, safe and efficient machining.

“One of the main advantages of the new CoroMill Dura aluminum-specific end mills is their versatile performance in all different types of roughing applications, while also offering finishing capabilities,” says Antti Wikström, global product manager, solid end mills, at Sandvik Coromant.“Up to 2×D full slot, pocketing, 5-20-degrees ramping, shoulder milling and more — all with the same end mill.”

The online CoroPlus Tool Guide for CoroMill Dura assists with tool and cutting data recommendations. “Having the right cutting data is, of course, a prerequisite for both secure and efficient machining,” says Wikström. “With the CoroPlus Tool Guide for CoroMill Dura, we can give the most accurate starting values for a specific application. And, if you have CAM software with the CoroPlus Tool Guide plug-in, you get the most relevant cutting data recommendations directly into your CAM program.”
