Accuracy Standard The accuracy of model CSKR is defined in positioning repeatability, positioning accuracy, backlash and running parallelism (vertical). Positioning repeatability After repeated positioning to a given point in the same direction seven times, measure the resting point and calculate the value of half the maximum difference. Perform this measurement at the center and at both ends of the travel distance; the largest value becomes the measurement value, and the positioning repeatability is expressed by placing the symbol "±" next to the value of half the maximum difference....
