827MA Edge Finder
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 centre with a decided wobble. At this point, the centre 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 centre points and scribed lines, the pointed contact is used by putting a pencil or rule against the centre point and making it run concentrically. Then the point is brought down to the centre point or intersection of scribed lines and the table is adjusted so that when the tool barely touches the work, the line-up with the point in question can be ascertained.
