When we grind the M325×1.5 and M260×3 thread ring gauges with the C8955 shovel, the thread half angle cannot be directly measured. We use the method of grinding the measuring block to check the half angle to ensure the accuracy of the half angle of the thread ring gauge, and the effect is better. As shown in the figure, the measuring block 6 is mounted on the combined jig (the self-made jig is also used), so that the axial cross section of the thread angle passes through the center of the machine tool rotation, that is, the center of the disc rotation, and one side of the flat key 5 of the combined jig is A.
