Ceramic End Mills Excel in High-Speed Roughing, Milling of Heat-Resistant Superalloys

Emuge-Franken, a manufacturer of high-performance taps, thread mills, end mills, drills and other rotary tools, introduces its Cera-Cut end mills featuring a high-hardness cutting ceramic head brazed to a carbide shank for optimal vibration dampening and longer tool life compared to one-piece ceramic tools. Featuring a high-feed duplex cutting edge geometry, Cera-Cut produces high metal removal rates in challenging nickel-based alloys, resulting in machining parts 200-400% faster than conventional carbide end mills. Also, the tool life of Cera-Cut is reported to be up to five times higher than regular carbide end mills.

“With the growing use of heat-resistant superalloys, we are pleased to offer our customers new, long-lasting, five-flute ceramic end mills for roughing and milling in these challenging applications,” Dan Doiron, manager, milling products, Emuge-Franken USA, says. “For example, Cera-Cut excels in the machining of complex aerospace parts.”

Cera-Cut End Mills are designed for the consistent cutting of high-temperature resistant materials such as Inconel, Hastelloy and Nimonic as well as the machining of hardened tool steels. Cera-Cut is also suitable for making interrupted cuts, and offers a tight cutting diameter tolerance ranging from -0.0008" to -0.0016" (-20 to -40 µm), depending on the tool diameter.

Cera-Cut end mills can be used for roughing or pre-finishing, can produce 2D or 3D contours and are suitable for face milling, slot milling, helical milling, contour milling and pocket milling. Emuge-Fraken Cera-Cut End Mills are offered in different diameters from 0.24 to 0.79" (6 to 20 mm). Corner radius, modular and special designs are also available.
