True squares are designed for fast, precision indexing with angle gage blocks. All faces of Webber True Squares are at precisely 90o to adjacent sides, with perfect optical flatness and parallelism to permit use with autocollimators. Applications for fast precision indexing and setting of angular grinding fixtures are almost unlimited. For example: the work and the true square are mounted together on a revolving fixture. A notch is ground by two successive cuts, one at 90o with the true square, and the other at 2o with the addition of two angle blocks (+3o and –1o) mounted on square. An indicator reading is taken before each grind. This process is then repeated by turning the True Square to successive zero readings. True Squares are designed for use as an accessory to our angle gage blocks to easily make angles greater than 45° and through 180°. Webber True Squares also permit a fast, easy check of indexing tables. The gaging faces are at precise 90° angles with optical flatness and finishes that permit the use of autocollimators.
