Edge Finder 寻边器

Edge Finder also known as a wobbler, edge-finder, center-finder or laser-centering-device, is a tool used with a machine like a mill, to accurately align the machine head with the work prior to machining.

寻边器是在数控加工中，为了精确确定被加工工件的中心位置的一种检测工具。寻边器的工作原理是首先在X轴上选定一边为零，再选另一边得出数值，取其一半为X轴中点，然后按同样方法找出Y轴原点，这样工件在XY平面的加工中心就得到了确定。
