摘要： An automatic tool exchanging machine include a machine body such as gear box, a tool exchanging arm having a tool grasping member and supported by the machine body to be rotatable and to be linearly reciprocally movable in an axial direction of a rotation shaft of the machine body, a rotation drive mechanism provided for the machine body, and a power transmission mechanism for transmitting a driving power of the rotation drive mechanism to the tool exchanging arm. The power transmission mechanism is provided with a motion conversion mechanism for converting a rotational motion of the rotation drive mechanism including servo-motors to a linear reciprocal motion of the tool exchanging arm and the motion conversion mechanism is composed of a feed screw mechanism. The feed screw mechanism is a ball screw mechanism.

摘要： A machine tool has a spindle with a tooling body mounted thereon, a detector for detecting an acceleration time for the tooling body to reach from a rotation start to a predetermined rpm, a controller for controlling an rpm of the spindle under a lowered limit when the acceleration time is longer than a reference time. Another detector detects an asymmetricity of radial forces acting on the spindle, and the controller controls the rpm of the spindle under a lowered limit when the asymmetricity of radial forces exceeds a reference degree.
