の下死点位置精度維持装置。[Scope of Claim for Utility Model Registration] Upper and lower limit position detectors that detect arbitrary upper and lower limit positions of the slide, and upper and lower limit positions corresponding to the number of times the slide is raised and lowered detected by the upper and lower limit position detectors. a storage means for storing the data; and a storage means for determining the distance change trend data between the two positions from the stored upper limit position and lower limit position, and from this data, the amount of change in the lower limit position of the slide at the bottom dead center is calculated as SPM.
It has a factor-separating means for determining whether it is based on a change or a temperature change, and a setting device for setting the lower limit position of the slide,
and a slide position adjusting means for adjusting the lower limit position of the slide at the bottom dead center, and based on the determination result of the factor determining means, drive-controls the slide position adjusting means to adjust the lower limit position of the slide corresponding to the SPM or temperature. A slide bottom dead center position accuracy maintaining device characterized by being configured to be able to correct the amount of change.
