An operation called 'tensioning' is performed on the disk of tipped-saw used in the cutting-off process in order to add a residual tensile stress and to raise consequently a natural frequency. The conventional tensioning method which deforms plastically the disk by roller and/or hammer requires a very high skill. This paper proposes two tensioning methods as named 'expansion fit' and 'internal pressure' in order to simplify the operation, and investigates the property of disk such as natural frequency, rigidity etc. In addition, the cutting-off performance of these tipped-saws is compared with that of the conventional method. The new methods proposed can prepare an adequate residual stress in the disk and consequently increase the natural frequency and the rigidity as same as the conventional method. When sawing S45C steel under low cutting speed, however, the cutting edge has broken down due to large amplitude of run-out of the disk and high sawing force from the beginning of sawing.
