By controlling the number difference of the end blocks 4, the finishing area of the measuring inclined plane 3 is reduced, and the manufacturing cost is reduced.
It should be noted that, when the verticality detection device composed of the dial indicator 6 and the cross rod 7 is used for measuring whether the main shaft is perpendicular to the measuring inclined plane, the dial indicator 6 can also be directly placed on the measuring inclined plane 3 and connected with the main shaft head through the cross rod 7, and the main shaft is judged to be perpendicular to the measuring inclined plane 3 through the indication differences of the dial indicator 6 at a plurality of positions of the measuring inclined plane 3 within the set difference. However, since dial gauges are placed at a plurality of positions on the measurement slope 3, it is necessary to ensure a finish area of the entire measurement slope, which increases the manufacturing cost compared to placing dial gauges 6 on a plurality of end blocks 4.
