Granite measuring tools

Granite measuring tools

No deformation: After long-term natural aging, the rock has a uniform structure, a very small linear expansion coefficient, and the internal stress completely disappears without deformation.

High hardness: good rigidity, high hardness, strong wear resistance, and small temperature deformation.

Long service life: no need to apply oil, not easy to stick to dust, easy and simple maintenance, long service life.

No scratches: no scratches, not blocked by constant temperature conditions, and can maintain its original physical properties at room temperature.

Non-magnetized: It can move smoothly during measurement without any sluggish feeling, is not affected by moisture, and has a good flat surface.

Physical properties: Specific gravity 2970-3070kg/m3 Compressive strength: 2500-2600kg/cm3 Elastic coefficient: 1.3-1.5x106kg/cm2 Water absorption.

Classification of granite measuring tools

Granite measuring tools generally include: granite testing platform, flat ruler, square ruler, square ruler, square box, V-shaped block, comparison table, etc.

granite platform

It is suitable for various inspection work and as a reference plane for accuracy measurement. It is used as a benchmark for machine tool inspection and measurement, to check the dimensional accuracy or behavioral deviation of parts, and to make precise markings. The granite platform is also an indispensable basis in machinery manufacturing. tool.

Granite ruler

Used to measure the straightness and flatness of workpieces and equipment installation. Flatness and straightness of machine tool tables, guide rails and precision work. To reduce weight and facilitate use, weight-reducing holes are added.

Granite square ruler

Suitable for measuring straightness, flatness and verticality of workpieces.

granite square ruler

It is mainly used to detect the parallelism, verticality and flatness of workpieces and machine tool guide rails and perform grinding processing.

Granite square box

Used for fitter three-dimensional marking of precision workpieces and measurement and inspection of parallelism and perpendicularity of mechanical parts.

Granite V-block

Used for verticality and parallelism detection, and can be used as a 90° absolute measurement benchmark. Granite V-Blocks are ideal tools for inspecting cylinders. If required, other surfaces can also be machined to the required precision.

Comparison bench

A height meter, mainly used for high-precision measurement of height, parallelism, flatness, etc. of precision parts.
