Product Description
Granite measuring base
It is composed of granite base and metal support, and needs to be combined with dial indicator, dial indicator, electronic measuring equipment, to accurately measure the flatness and parallelism of parts.

Granite V-shaped block
Its V-shaped notch design can effectively disperse the pressure, improve the bearing capacity of stone, and play an important role in the detection, marking, calibration and assembly of precision shaft parts.
Granite parallel ruler
The Granite parallel rule is mainly used to measure the parallelism and straightness of parts, each two for a group, widely used in industrial production and laboratory measurement work, can replace the use of equal height blocks, to ensure the high precision and stability of measurement.
Granite flat ruler
It is mainly used to measure the straightness of parts, and check the flatness and straightness of machine table, guide rail and precision work, suitable for industrial production and laboratory measurement work.
Granite square ruler
It is a professional measuring tool, mainly used to detect the verticality and parallelism of parts, to ensure the accuracy of product processing and equipment installation, and is widely used in precision measurement and calibration work in the machining industry.
Granite square box ruler
It is mainly used for three-dimensional marking, flatness inspection, verticality measurement and other tasks of precision parts, especially in machine tool assembly and electronic original parts production;
Used to measure the straightness and verticality of workpieces and equipment installation and debugging to ensure the accuracy and stability of the equipment.
It is an ideal datum surface for high-precision measurement and inspection of instruments, precision tools, and mechanical parts.
Granite four sided square ruler
It is an important measuring tool, mainly used for high-precision machinery and instrument inspection and verticality inspection between machine tools. with vertical and parallel frame combinations, it is suitable for the inspection of various high-precision machinery and instruments, especially for checking the perpendicularity between internal parts of machine tools.
It is composed of granite base and metal support, and needs to be combined with dial indicator, dial indicator, electronic measuring equipment, to accurately measure the flatness and parallelism of parts.
