Estimating the term…
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.
A measuring device comprising:
A method for measuring a workpiece using a measuring device including a spindle provided to be movable reciprocatively in an axial direction through a housing part and a lever-type contact point to be attachable to a tip of the spindle and including a contact point at a tip of a lever part extending in a direction intersecting an axis of the spindle, wherein the housing part includes a bearing part configured to guide the spindle to move linearly, and the bearing part is a ball bearing, and the lever-type contact point includes a base that is attachable to or detachable from the tip of the spindle, and the lever part is a shaft supported by the base to freely rotate and be fixed at a desired angle, the method comprising:
