Angle Gage Block Sets
Angle Gage Blocks permit fast, simple and accurate measurements of any angle. They are far superior to sine bar measuring methods, that involve trigonometric formulae and complex stacks of gage blocks.
Standard Reference Bars
Standard Reference Bars are used in checking table movement of machine tools, accuracy of Vernier height gages, surface plate transfer measurement, and final inspection of precision machine tools.
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.
Stable and maintenance free, reflecting cubes are ideal for 90° indexing or alignment in optical tooling or inspection. Reflectivity: 55% in the visible spectrum and >80% at 10.6 microns.
Chrome Carbide Polygons are indispensable optical tools for checking angles and flatness.
Fused Quartz Optical Flats
For visually checking the flatness of seals, gages and mating surfaces. Through means of interpreting light interference patterns or bands, the optical flat provides a simple, accurate precision method for measuring surface flatness.
Gage Block Stones
If a block does not wring together with other blocks, it may be the result of nicks or other damage. Examine blocks carefully with a magnifying glass. If a small burr is found, it may be removed with a gage block stone.
These Starrett-Webber synthetic chamois cloths, rather than natural chamois, are recommended for wiping gage surfaces.
