La plaque d'échelle d'angle comprend, dans une partie de rotation, un bloc calibre fixe que l'on met à nouveau en regard d'une valeur de sinus d'un angle désiré, le bloc calibre étant utilisé comme référence, ce qui permet d'affûter avec précision le dessous de la lame d'un outil et le premier et le second angle de la lame de coupe périphérique. Le corps de la partie d'affûtage est divisé en une partie supérieure et une partie inférieure de façon que le corps supérieur tourne selon un angle désiré et en même temps, et la plaque d'échelle d'angle est formée de façon qu'elle permet à un ouvrier de vérifier l'angle à l'état de rotation, et de former de la sorte un angle sphérique sur l'outil.
