Bridge Type Straight Edge

The bridge type straight edge which applies HT250 as its raw materials, is manufactured in compliance with the JB/T7977-99 manufacturing standard. Its working surface is processed with the scraping technology. Our precision straight edge is mainly used for inspecting the flatness of flat plate, long guide rail, etc., through the coloring method or dial gauge. Moreover, it can be applied to inspect the straightness of the workpiece by the method of light-gap testing.
