No. 827
Series Edge Finder
Work surfaces may be located easily, quickly
and accurately with these edge finders. Work with flat, straight edges,
shoulders, grooves, round work, studs, dowels, or center points and scribed
lines-all can be accurately located with this handy tool. Body and contacts
are made of tool steel, hardened, ground and lapped to close tolerances
for diameter and concentricity.
How To Use:
Edge finders are easy to use. They are placed in a collet or chuck.
The worktable is then traversed to obtain contact between the rotating
edge finder and the work. Contact will shift to concentric position relative
to the body and with very slight additional table adjustment, will move
off center with a decided wobble. At this point, the center of the finder
is exactly one-half the diameter of the contact from the work edge, permitting
accurate location for other machining operations relative to the edge.
For locating center points and scribed lines, the pointed
contact is used by putting a pencil or rule against the center point and
making it run concentrically. Then the point is brought down to the center
point or intersection of scribed lines and the table is adjusted so that
when the tool barely touches the work, the lineup with the point in question
can be ascertained.
