Cast iron ruler

The cast iron ruler is manufactured according to the standard, with material HT250. The working surface adopts scraping or grinding technology for measuring the straightness and flatness of the workpiece and equipment installation. The operating temperature is (20 ± 5 ℃).

The main use of cast iron rulers is for precision inspection of machine tool guides, workbenches, geometric accuracy measurement, component measurement, scraping and grinding process processing, etc. It is the benchmark for measurement.

When using a cast iron ruler, the working surface should be cleaned thoroughly. For larger sizes of cast iron rulers, nylon material lifting ropes should be used in conjunction with lifting, and the operating temperature should be (20 ± 5 ℃). The correct storage method for cast iron rulers is to hang them vertically.

The cast iron ruler is manufactured according to the standard, made of HT250 material. The working surface is scraped or ground to measure the straightness and flatness of the workpiece and the installation of the equipment. It is used at a temperature of (20 ± 5) ℃ and is suitable for inspecting unevenness and straightness in machine tool testing. The two working surfaces are inspected with instruments such as block gauges, micrometers, and level gauges.

Cast iron rulers include bridge shaped rulers, I-shaped rulers, rectangular rulers, angle rulers, and rulers used for precision inspection of machine tool guides, workbenches, geometric accuracy measurement, component measurement, scraping and grinding process processing, etc. They are the benchmark for measurement.

The material of rock rulers, granite rulers, and marble rulers is Jinan blue, while marble rulers have a black luster, uniform structure, good stability, and high strength,. It is a benchmark measuring tool made of stone material, which is an ideal reference surface for the inspection of instruments, tools, and mechanical parts, especially for measurement purposes.

A cast iron ruler is a tool used for maintenance and measurement. The bending point of general steel materials is 30kg/mm2, the bending point of general cast iron parts is 38kg/mm2, and the bending point of cast iron rulers reaches 110kg/mm2. The bending resistance index is far superior to other materials.
