What are edge finders?
Edge finders are tools used to locate the edge of a workpiece during machine setup operations by using an X and Y axis. They are also referred to as center finders or wigglers, and are used in some machine spindles. Edge finders are used in machining applications to locate a specific distance on the edge of a machine part.
What do you use the V end of an edgefinder for?
well i use the V end to locate the center of slots and grooves that are too small for the .200" section to fit into. i have seen people use that for picking up transfer or center punch dimples and ive seen the edgefinder shatter when the user gets a little heavy handed, even have one myself to remind me what not to do .
How can you tell if an edge finder tool is concentric?
In principle, when the wobbling end is precisely touching the surface, the edge finder tool will be running perfectly concentric. However that’s pretty much impossible to see by eye. If it’s close-but-not-quite concentric, you won’t be able to tell.
How do you use an edge finder stub?
When chucked in the mill, the edge finder’s stub will wobble around like crazy, because it’s free to do so. To use it, you run the spindle at a moderate-to-high RPM (say 1000) and bring the wobbling end up to the workpiece.
How accurate is an edge finder?
This style of edge finder is considered to be the most accurate, and its accuracy can be further improved through the use of a collet. In proper setups, a repeatability of 0.0002 in (0.0051 mm) or better can be obtained.

What is the purpose of an edge finder in milling machine?
Edge finders are used in machining applications to locate a specific distance on the edge of a machine part. They should be used before any work is done on the milling machine. It is composed of two concentric cylinders, spring loaded together.

What is a wiggler on a spindle?
It is a pointer that can be accurately and easily located on the centerline of the longitudinal axis of the spindle to which is attached. Once the spindle is turning at 1000 rpms, the probe is centered and the user can visually center the workpiece under the spindle.

What is a DRO machine?
A “DRO” (as the cool kids call them) is a little computer that knows where the slides are, and thus where your cutter is on the piece . However, there’s a catch. DROs don’t know the absolute position of the spindle, they know the relative position of it. The bottom line is that a DRO is just a fancier version of the graduated scales on the hand wheels. The key difference is that the DRO doesn’t suffer from backlash, because it is measuring the slides directly (via glass scales similar to your digital caliper) rather than inferring position from rotations of the leadscrews. With traditional hand wheels, you have to compensate for backlash every time you change direction, and a DRO saves you from that (among other convenience features).
Why do you need to edge find?
Edge finding is a main reason why. If all your numbers are relative to the same corner , the machinist only has to edge-find once, and there will be less accumulated error from resetting the origin. Either that, or the machinist has to do math to recalibrate all the numbers you gave to be relative to the same place. Both scenarios will make said machinist angry. Help heal the generations-old rift between engineers and machinists by minding your origin. If you don’t, expect to someday find a chuck key on the wrong side of your broken window.
What is a DRO in computer science?
A “DRO” (as the cool kids call them) is a little computer that knows where the slides are, and thus where your cutter is on the piece. However, there’s a catch. DROs don’t know the absolute position of the spindle, they know the relative position of it.
