PURPOSE:To perform cutting operation even for a large work without causing the deterioration of accuracy, by operating a rotary cutting tool applied not only with its swing feed but its slide feed. CONSTITUTION:A guide shaft 4 is positioned in an optional place for a work 30. An operating handle 17 is gripped and lifted upward, then a grindstone 14 is swingably moved to a position of the grindstone 14', thus a work 30 is cut off by the grindstone against the tension of a spring 33. In case for a large work, cutting operation is started with the method of swing feed, then operating action of a handle 8 both horizontally slides the guide shaft rightward and move the grindstone also rightward, easily permitting the cutting operation even for the large work. |
