WebThe best and fastest method for checking plate flatness is the use of a Flatness Gauge. This consists of a dial indicator (calibrated to 0.001mm) supported on three points and set to zero on a known flat test piece. The gauge can be used to take readings over several areas of the Lapping Plate. WebThe wedge between the surface of the work and the optical flat may be: Too thick. Press down on the optical flat with a uniform pressure to squeeze out the air film. Too thin. If moisture or oil is present if may cause the optical flat to wring or adhere to the work so closely that bands cannot appear. Too angular.

WebFlatness – The condition of a surface having all elements in one plane. Parallelism – The condition of a surface, line, or axis which is equidistant at all from a datum plane or axis. It's not rocket science. ... Flatness is a feature compared to itself, while parallelism requires that a feature be compared to a datum. Think of a table with two WebJoined Table Systems can be configured with any of our optical tables. Our joiner plate system provides a rigid coupling between sections. ...
