METHOD FOR MACHINING A VERTICAL ROLL WITH AN INCLINED CIRCUMFERENCE SURFACE

PURPOSE: A machining method of a vertical roll having an oblique outer peripheral surface is provided to prevent a malfunction of a machining machine by preventing machined chips being scattered to the upper part while machining a vertical roll. CONSTITUTION: A machining method of a vertical roll(12) having an oblique outer peripheral surface(12a) is as follows. A rotary shaft(12b) of a vertical roll having an oblique outer peripheral surface is installed in the vertical roll machining machine to upward and downward directions and rotates. A bite(152) of the vertical roll machining machine moves from the lower part to the upper part, thereby machining the oblique outer peripheral surface of the vertical roll.
