An operation called tensioning has be performed on the tipped saw used in the sawing for two purposes of the addition of residual tensile stress and the increase of natural frequency. The conventional tensioning method requires a great amount of skill. This paper describes new tensioning methods. One is an expansion fit tensioning and the other is an internal pressure tensioning. The cutting performance of these tipped saws produced by new methods is compared with that of the conventional one. An adequate residual stress is generated by the new methods, and the natural frequency of the disk is increased. At a high sawing speed of 1916m/min, the new method has the same wear resistance as the conventional tensioning method, but cannot saw at all at a low speed of 100m/min.
