Note The cutting conditions above are a guide. Actual conditions will need to be adjusted according to machine rigidity, work clamp rigidity, depth of cut and other factors. ■ Recommended Values for Helical Milling and Ramping Precautions for Helical Milling Recommended Values for Helical Milling and Ramping For Minimum Diameterand Below WEX1000 (AX□T06···) WEX2000 (AX□T12···) WEX3000 (AX□T17···) ø Center uncut portioncannot be removedCutter Dia.
