The set contains two edge finders, large and small, a center finder (pointer) and an indicator arm.

The machines I use at work have digital probes but it gets does get used, mainly for the occasional job on a manual machine. Using an MPG pendant makes this process a whole lot easier than using your keyboard to do this.Īlways double check the step increment distance you have active in your software to avoid wiping out your edge finder as you get closer to the part.
These instructions apply to most edge finders including the wiggler or wobbler style of tool. Adjust the offset to account for the radius of the contact head.When it is exactly against the edge, the contact head will move to one side.As it starts to get close to centering, reduce step increment to.When it touches, the contact head will start to center up to the body.Move the required axis incrementally toward the part.Set the RPM of the spindle to approx 700rpm, no more than 1000 rpm.Manually position the contact head close to the edge to be touched.The contact head is pushed to one side so that it is off center.The edge finder is gently tightened in the spindle collet or chuck.

How to use an Edge Finderĭifferent styles of edge finder are used in slightly different ways but I will explain how the most common type, as described above, are used in a cnc machine. The surface finish on the end of the main body and the contact head is especially important as they have to slide against each other with as little friction as possible.Īlso, the part of the contact head that touches the edge has to be ground to an accurate known diameter so the position of the center can be easily calculated.
The main body and the contact head are made of hardened steel and ground to a fine finish.
