Abstract: There is provided a measuring device that is inexpensive and easy to use, yet provides sufficient accuracy and resolution in continuous scanning measurement to measure workpiece surfaces. A dial gauge includes a spindle provided to be movable reciprocatively in an axial direction through a main body case. The main body case includes a stem provided to protrude from a side face of the main body case. A ball bearing that bears the spindle is provided inside the stem. A workpiece and the dial gage are relatively moved while a contact point at the tip of the spindle is in contact with the surface of the workpiece, and continuous scanning measurement is performed to measure irregularities of the surface of the workpiece or the amount of runout of the rotating workpiece.

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 method of placing a work piece on a measuring device in which a work piece is placed on a table of a measuring device is provided. The method includes: using a retainer capable of holding the work piece above the table and a lifting/lowering device lifting and lowering a top surface of the table; holding the work piece above the table with the retainer; lifting the top surface of the table with the lifting/lowering device to bring the top surface of the table into contact with a bottom surface of the work piece; and, after a load of the work piece is borne by the table, releasing the hold of the retainer on the work piece.

Abstract: The invention discloses a method for roundness measurement, which includes the steps of, mounting and rotating an object on a rotary table; driving two measuring surfaces of two measurement units to respectively abut against two opposite sides of the object, wherein the two measurement units are disposed on two opposite sides of the rotary table and the two measuring surfaces are parallel to each other and perpendicular to a to surface of the rotary table; during rotation of the rotary table, measuring intermittently a shortest straight line distance between the two measuring surfaces and generating a variation data and after the rotary table completes a full-circle rotation, a processing unit receiving the variation data and generating measured data. The present invention also discloses a device for roundness measurement.

Abstract: A measuring device for in-process measurement of test pieces during a machining operation on a machine tool, in particular a grinding machine, has a base body, and a measuring head movable between a neutral position and a measuring position and which is connected to the base body via a rod assembly which is configured and set up in such a way that the measuring head in the measuring position follows orbital rotations of a test piece about a rotational axis. The measuring head has a measuring sensor which is deflectable along a linear axis for recording measured values during a measuring operation. A control apparatus is provided for controlling the measuring operation. The control apparatus is configured and set up in such a way that the measuring device may be calibrated in a calibration mode.
