Abstract

A feeder for a machine tool adapted to move a table relative to a saddle by rotation of a motor includes a ball thread nut fixed to the saddle and a ball thread shaft that engages with the ball thread nut in a rotatable manner but is immovable in an axial direction of the ball thread shaft relative to the table. The motor is fixed to the table and the ball thread shaft is coupled to the motor. A sum of a movable distance of the table relative to the saddle and a length of the saddle in the axial direction is shorter than a length of the table in the axial direction. The feeder further includes rails fixed to the table on its surface where the motor is fixed and bearings that are fixed to the saddle and bear the rails.
