  • Publication number: 20210299732
    Abstract: 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.
