Claims

[Claims for Utility Model Registration] (1) It has a processing unit that can move forward and backward with respect to a first processing station and a second processing station, and the processing unit is disposed in the first and second processing stations. first and second spindle heads facing respective workpieces; at least one set of spindles to which a machining tool is attached and coaxially supported by the first and second spindle heads; When one spindle constituting a set of spindles is rotated in the processing direction under the action of an actuator with the direction directed toward one workpiece, the other spindle constituting the set of spindles is directed toward the other workpiece. 1. A double-headed processing device, comprising: a rotational direction converting means for rotating in a processing direction. (2) The device according to claim 1, wherein the rotational direction changing means includes first and second bevel gears pivotally attached to mutually opposing ends of a pair of spindles, and the first and second bevel gears. It consists of one or more third bevel gears that integrally mesh with the gear, and one spindle is rotated in one direction under the action of an actuator, and the other spindle is rotated through the first to third bevel gears. A double-headed processing device characterized by being configured to rotate in the opposite direction. (3) The apparatus according to claim 2, wherein at least one spindle sleeve is supported in the first and second spindle heads so as to be freely movable and retractable, and a set of spindles is rotatably disposed on the spindle sleeve, and A double-headed processing device characterized in that the spindle sleeve rotatably supports two third bevel gears constituting rotational direction changing means.
