Abstract

PURPOSE: To make possible the cutting work for the curved groove to be effectively executed, by permitting the guide roller to guide the travel of the main body of secateurs, which is provided with the cutting torch equipped with the angle adjuster, and is supported by three wheels.
CONSTITUTION: The cutting torch is equipped in the main body 4 of the secateurs which is supported by a free front wheel 2 and two rear wheels 9. Besides, the angle adjuster 6 for changing the torch angle, and the angle adjuster's driver 7 being connected to the angle adjuster 6, are attached to the main body 4. The front wheel 8 is fixed so as to always face inward against the line of groove cut; the guide roller 5 being attached approximately horizontally to the side of the main body 4, is set along the side plane 11 of the parent metal 3. The torch is set on the estension of the root face, and is fixed at suitable height; and then, the main body 4 is traveled being guided by the curved side plane 11 of the parent metal 3. According to this method, the groove cut can be effectively executed for the parts especially like as the casing body of the hydraulic turbine in which the curvature gradually varies and the groove angle also must be varied.
