Grade for High-Performance Cast Iron Milling
November 1, 2014
WIDIA has introduced its latest WK15CM grade for face mills, shoulder mills and copy mills with dedicated geometries for cast iron milling. Parts made of grey cast irons form the foundations of many industries, including automotive, energy, fluid power, heavy equipment and more.
WK15CM features a fine-grained alumina layer to give better wear resistance by improving coating integrity at elevated speeds. Proprietary post-coat treatment of the WK15CM inserts is designed to further increase cutting edge toughness by improved coating stress. "This helps fight thermal cracking and coating flaking, the number one reason most milling inserts fail in machining cast irons, especially when coolant is applied," said a company spokesperson.
Cutting edges are further micro-polished to help ease cutting forces and reduce friction and workpiece sticking. "Cutting tests for WK15CM are showing up to 40% longer tool life," said the spokesperson. "The result is an extremely reliable milling insert shops can use to make more cast iron parts or to ramp up cutting speeds when increased performance is called for."
