flatness gauges

Flatness Gauges

(11)
The Lapmaster Flatness Gauges provides a quick, reliable method of inspecting lap plates, polishing plates, surface plates and other large surfaces for flatness. The Flatness Gauge determines flatness by measuring the deviation from a straight line on a plane determined by the gauge body. This deviation, convex or concave, is then read directly in .0001 increments on a dial indicator (digital indicators also available). Lapmaster manufactures flatness gauges with 4-3/8" between centers for plates up to 15" diameter and 9-3/8" between centers for plates of 20" diameter and larger. Lapmaster also manufactures a line of flatness gauges specially designed for use with dual face machining plates.

SPI Interferometer

(2)
Lapmaster International’s SPI Interferometers with grazing incidence are an inexpensive, fast and accurate means for flatness inspection of ground, fine ground, lapped or polished parts. Flatness readings of non-reflective ground surfaces on all materials are clearly displayed as easily read fringes. Contact Lapmaster International to receive a light band (fringe) reading chart on an accompanying monitor. Eliminate secondary polishing operations, where polishing is performed only for the purpose of checking for flatness with optical flats (secondary polishing can alter flatness characteristics of the original lapped or ground surface). Whether used directly next to the lapping, fine grinding or grinding machine, or in the inspection ...

Instuments for Fast, High - Accuracy, Non - Contact Flatness Measurement of Precicsion Parts.
  • Instruments for non-contact flatness measurement of precision-manufacturing surfaces with sub-micron accuracy. They meet the requirements for objectively working measurement tools for the production and quality control of sophisticated components, such as those being utilized, for instance, in fuel injection systems, pumps or valves.
  • The measurements principle is based on interferometr y with grazing incidence of light. This set-up allows for flatness measurements of polished as well as non-reflective, rougher surfaces, which would not be measurable with traditional interferometers for flatness testing.
