Three New Milling Grades with Advanced Technology

Walter has introduced the WKK25S, WSM45X and WNN15, a trio of new milling grades that offer an array of benefits due to Walter's use of innovative cutting tool technology.

"WKK25S features Walter's Tiger·tec Silver PVD cutting tool material, providing increased hardness (from 2200-2500 Vickers to 2500-2800), higher crystallization and significantly decreased number of micro defects in the coating surface," said a company spokesperson. "All this translates to increased cutting speeds and higher cutting edge life. WKK25S is specially suited for the machining of cast iron materials.

"WSM45X, with Tiger·tec Silver CVD and post treatment, offers process reliability and excels at the machining of stainless steel (ISO M) and super alloys (ISO S)." It has a broad application area that includes common aerospace materials. In field tests, WSM45X has shown tool life improvement of up to 50% and increases in material removal rate of 25%, the company reports.

Walter's WNN15 features innovative PVD technology. Known as High Power Impulse Magnetron Sputtering (HIPIMS), the new coating technology results in very dense and smooth coating layers. For the user this means reduced friction, significantly reduced build-up edge, good resistance against flank wear and good cutting edge stability. Particularly effective with ISO N materials, application areas for the new grade include demanding aerospace work.
