What Is A Granite Surface Plate

The granite used in a granite surface plate is graded by quality with these four levels of quality.

What is a granite surface plate.

Final inspection and calibration of every surface plate is accomplished by use of the auto collimeter. They provide a high modulus of rigidity and are moisture free. Granite surface plate have more rigidity for the same depth with the absence of corrosion. The properties of granite such as weight resistance and durability create a super smooth surface that is easy to maintain.

36x72x6 b0 precision granite b grade tool room surface plate 36 x 72 x 6 the 36x72x6 b0 precision granite b grade tool room 36 x 72 x 6 surface plate is on sale at gagi. The intervals between calibrations depends on the environment where the surface plate is located. Granite surface plates meet or exceed federal specifications ggg p463. Their high degree of flatness overall quality and workmanship also make them ideal bases for mounting sophisticated mechanical electronic and optical gauging systems.

Grades of granite to consider when looking at a granite surface plate for sale. Read full article here. Solid granite surface plate and angle plates are used for precision layout inspection and tooling setup. Granite surface plate maintenance may be easy but it is still important to perform regular checks and cleaning.

These stands have three plate support points to match the support points on most granite plates as defined by fed. Metallic objects like manufactured components jobs can easily slide on their surface. The surface plate is a massive solid structure highly rigid in design which is having a true flatness of the surface. For technical drawings and 3 d models click on a part number.

Surface plates come in grades of a aa b and ht200 for different applications. A this is an inspection grade granite surface. The foundation of precision measurement is the surface plate. The granite used for surface plates has an excellent distribution of hard quartz which provides a smooth long wearing working surface.

Granite surface plates are considered the more superior material compared to cast iron surfaces. When needed lapping or resurfacing is provided to bring measurements within grade guidelines. Standridge granite surface plates provide an accurate reference plane for work inspection and for work layout. 48x60x6 b0 precision granite b grade tool room surface plate 48 x 60 x 6.
