摘要： To provide a rod member feeding device that reduces the load on a spindle chuck and a finger chuck when a rod member is positioned, as well as providing a machine tool provided with the rod member feeding device, and a control method for the rod member feeding device. A rod member feeding device includes: a feed rod for supplying a rod member to a spindle; a servomotor for moving the feed rod along the axial direction of the spindle; and a control device (exemplified with a motor control device and a control device) for controlling the driving of the servomotor. The control device calculates a deviation between a command position based on an advance amount of the feed rod and the actual position of the feed rod that has been actually advanced by the driving of the servomotor, and controls the driving of the servomotor based on the magnitude of the deviation.

摘要： A sample mounting plate has: a substrate made of alumina ceramic which exhibits white; and a cover layer which is laminated so as to cover the front surface of the substrate and which has multiple grooves formed in some areas. The cover layer has: a conductive interference layer which exhibits conductivity and is configured so as to exhibit a prescribed color (such as navy blue) through light interference and which is laminated on the substrate; and a water-repellent layer which exhibits higher water repellency than that of the substrate and is laminated on at least a part of the conductive interference layer and on which a sample is to be mounted.
