Nov 1997Precision SolutionsRequest Info
Precision-Optical Engineering has added a laser position-feedback interferometer to one of its large CNC lathes, giving its diamond turning facility an inherent machining accuracy of 2.5 nm. The company has also added a CNC-controlled angle-dividing head to its fly-cutting lathe, which will allow it to produce more accurate multifacet metal polygon mirrors for scanning applications. POE can now manufacture polygons with square, fixed-angle or varied-angle facets with a >2-arc-sec facet-to-facet accuracy.
