ト装置。[Scope of claims for utility model registration] (1) A slide table that moves back and forth on the field unit, and a slide table that is fixedly attached to the slide table,
and a housing that rotatably supports a spindle having a rotation axis parallel to the reciprocating direction of the slide table, and a cutting tool attached to the tip of the spindle via a tool holder, and the slide table rotates while driving the spindle. Boring processing in which the workpiece is bored by moving the tool forward, and after the slide table moves forward to a predetermined position, the rotation of the spindle is stopped and the slide table is moved backward to retract the tool. In the device, the spindle is rotatably supported by the housing via a bearing metal, and the slide table stop device stops the slide table when the slide table advances to a predetermined position, and the cutting tool is positioned in a predetermined rotation direction after the slide table is stopped. A tool retracting device comprising: a rotation stop device that stops the rotation of a spindle so that the rotation of the spindle is stopped; and a pressing device that presses and urges the spindle in a direction in which the cutting tool separates from the processing surface when the slide table retreats. (2) The tool retracting device according to claim 1, wherein the bearing metal is a partial bearing. (3) The tool retracting device according to claim 1 or 2, wherein the pressing device has a piston that is reciprocated by a hydraulic cylinder, and the top of the piston presses and biases the spindle in a direction in which the cutting tool separates from the processing surface.
