That is to say, a precise measuring block is used to stick to the left end face of the rack, fixed with 502 glue, and 2 - Φ 15.09 steel ball is placed in the tooth slot, and fixed with 502 glue as well. It is placed as close as possible to the two end faces of the rack, about 5-10 mm from the end faces of both ends, so as to facilitate the measurement of the outside micrometer. When measuring, it is not allowed to contact with the two sides of the tooth slot. The parallelism and flatness of the two sides of the measuring block are required to be less than 0.005. During measurement, measure 36.1 dimension with outside micrometer, then measure 115.12 dimension, then remove measuring block, measure 95.45 dimension, and calculate:
