H ^SMSU'JEii! Features and Applications Announcing the development of a radius mill with a long cutting flute to enable machining even of non-uniform work material formed by casting without worrying about the cutting amount. Even if the cutting amount of the work material is not uniform, rough machining of shaped area by contour machining can be performed. Can also be used for rough machining of flat surfaces of structural areas. Compared to ball end mills of conventional machining methods, this new radius mill offers great leaps in efficiency. Conventional machining method Heavy radius mill...

Cautions regarding handling (1) When removing the tool from the case (package), be careful not to drop it on your foot or drop it onto the tips of your bare fingers. (2) When actually setting the inserts, be careful not to touch the cutting flute directly with your bare hands. 2. Cautions regarding mounting (1) When preparing for use, be sure that the inserts are firmly mounted in place and that they are firmly mounted on the arbor, etc. (2) If abnormal chattering occurs during use, stop the machine immediately...
