The use of cast iron ruler

Used for precision inspection, geometric accuracy measurement, component measurement, scraping and grinding process processing of machine tool guides and workbenches, it is the benchmark for measurement.

Featuring a vertical and parallel frame combination, suitable for mechanical and instrument inspection, as well as checking for non perpendicularity between machine tools It is an important tool used to check the non perpendicularity between various components inside machine tools.

The working face adopts scraping or grinding technology for measuring the straightness and flatness of the workpiece and equipment installation
