Abstract: A measuring probe for measuring a screw groove of a relatively rotatable ball screw includes a stylus having a tip end portion configured to contact the screw groove, a radial-direction displacement mechanism configured to support the stylus so as for the stylus to be displaceable in an X direction toward an axial center of the ball screw, an axial-direction displacement mechanism configured to support the stylus so as for the stylus to be displaceable in an axial direction (Z direction) of the axial center, and sensors configured to detect displacement of the stylus produced by the radial-direction displacement mechanism and the axial-direction displacement mechanism. This enables high-accuracy measurement of a predetermined position of a side surface of a relatively rotatable work.

Abstract: A roundness measurement device provides a rotation table on a base and measures roundness of a measured object placed on the rotation table while rotating the rotation table, and includes a detecting main body, a detecting device driving mechanism, a stylus, a contact member, and a control device. The detecting device driving mechanism displaces the detecting device main body with respect to the base. The stylus has a base end rotatably supported on the detecting device main body and can change an angle position with respect to the detecting device main body using an external force. The contact member is provided at a position where the stylus comes in contact due to displacement of the detecting device main body by the detecting device driving mechanism. The control device controls driving of the detecting device driving mechanism.

Abstract: A roundness measuring machine includes: a base; a table rotatable relative to the base; a probe configured to scan a surface of a workpiece mounted on the table; a motor configured to rotate the table; and a control device configured to control a rotation of the motor. The control device includes: a starting current detector configured to detect a starting current of the motor; and an acceleration/deceleration time setting unit configured to detect at least one of acceleration time and deceleration time for the motor in accordance with the starting current. The roundness measuring machine can suitably set the acceleration time and the deceleration time for the motor corresponding to the inertia moment of the workpiece mounted on the table.
