The detection instrument is the same as that used for detecting the positioning accuracy. The general detection method is to measure at any three positions near the middle point and two ends of each coordinate stroke, and each position is positioned by fast movement, and the positioning is repeated for 7 times under the same condition, so as to measure the value of the stop position and calculate the large difference value of the readings. The coordinate is repeated with one half of the difference in three positions and with positive and negative signs, and the repeated positioning precision is the basic index reflecting the stability of the axis motion precision.

But when the numerical control lathe can detect straightness and verticality, the main shaft of the numerical control lathe is deflected, and at the moment, cutting fluid or other scraps and the like basically exist in the numerical control lathe, and when the objects are stuck on the dial indicator, the degree line of sight of the dial indicator can be influenced, and the dial indicator is extremely easy to read inaccurately when the objects are cleaned.
