Kadimi international offers osg corporation japan`s new wxs solid carbide endmills for ultra hard machining. These endmills are suitable for machining 45-70 hrc. Wxs coating is a new coating developed by osg to meet the requirements of high speed milling of hardened steel. Wxs endmills allow for milling of 65 hrc materials at 60,000 rpm. Wxs oxidizes at over 1,300 c compared to tiain, which oxidizes at about 875 c. This allows for machining at much higher sfm with the wxs coating. Higher sfm means higher rpm. In turn, higher rpm means higher feed rates thus reducing cycle times. The wxs coating has a coefficient of friction of 0.3 to boot, while tiain has a coefficient of friction of 0.8, giving wxs coated tools more lubricity. Better lubricity allows for extended tool life and superior surface finishes, but to benefit from this greater lubricity, this new coating must be run at higher rpm. Endmills are available in standard sizes [square & ball nose] and for rib processing.
