Wiggler (tool) : ウィキペディア英語版 | Wiggler (tool)
A wiggler, edge-finder, or center-finder is a tool used in the spindle of a machine such as a mill. The device is used to accurately determine edges or markings and therefore the center of a workpiece or a previously machined feature during the set-up phase of a machining operation. ==Edge finder==
A rotating tool, meaning the machine spindle must be turning for the tool to work. On one edge a cylinder shape is spring-loaded, when the edge finder touches an edge a kickoff of this cylinder is noticed. On the other end a cone shape is also spring-loaded and is used to locate the center of a previously drilled hole. Most accurate of all edge finders. Improved accuracy is obtained by use of collet. Repeatable to or better.
