抄録

The effects of ultrasonic sawing (frequency 19.7kc, amplitude max 7.5μ) of the aluminum, brass, duralumin, mild steel etc, by using the hack sawing machine, were investigated. The results were as follows : 1) A built-up edge and residual chip were not obsereved in the ultrasonic hack saw even for soft material. 2) The cutting time is decreased to about 1/2∼1/4 of the conventional sawing. 3) This ultrasonic hack saw was able to cut-off the brittle material smoothly, for example tellurium, which is easily cracked by the conventional sawing cutting resistance. 4) It was proved that this ultrasonic hack sawing was a very effective cut-off process.
