Parallel square ruler

　　Cast iron platformCast iron square ruler product alias: square ruler, cast iron square ruler, inspection square ruler, rectangular angle ruler, square angle ruler, parallel square ruler, equilateral square ruler

Angle rulers and specialized rulers are used for machine tool guides,Customized cast iron partsThe accuracy inspection, geometric accuracy measurement, precision component measurement, scraping and grinding process processing of the workbench are the benchmarks for precision measurement.

Cast iron ruler: manufactured according to JB/T7977-99 standard, material HT250, working surface adopts scraping or precision grinding process,Testing PlatformUsed for inspecting unevenness and straightness in machine tool inspection, the two working surfaces are inspected using instruments such as block gauges, micrometers, and level gauges. At different heights, the parallelism of the two guide rails and the levelness of the unconnected guide rails are checked,Cast iron platformAnd it can be used in conjunction with a square ruler to measure the perpendicularity of two components that cannot be inspected with a square ruler alone. It is also suitable for equipment installation and inspection.
