What Is A Granite Surface Plate

The intervals between calibrations depends on the environment where the surface plate is located.

What is a granite surface plate.

Solid granite surface plate and angle plates are used for precision layout inspection and tooling setup. The granite used in a granite surface plate is graded by quality with these four levels of quality. They provide a high modulus of rigidity and are moisture free. Granite surface plate calibration should be performed routinely to maintain proper flatness and ensure measurement accuracy over time.

Construction of surface plate required material properties to make materials used to make surface plates cast iron surface plate granite surface plates glass surface plates. Metallic objects like manufactured components jobs can easily slide on their surface. For technical drawings and 3 d models click on a part number. Read full article here.

These stands have three plate support points to match the support points on most granite plates as defined by fed. A this is an inspection grade granite surface. Grades of granite to consider when looking at a granite surface plate for sale. Use grade aa laboratory plates for precision operations in constant temperature gaging rooms and metrology departments.

When needed lapping or resurfacing is provided to bring measurements within grade guidelines. The foundation of precision measurement is the surface plate. The surface plate is a massive solid structure highly rigid in design which is having a true flatness of the surface. Granite surface plates are considered the more superior material compared to cast iron surfaces.

Their high degree of flatness overall quality and workmanship also make them ideal bases for mounting sophisticated mechanical electronic and optical gauging systems. Granite surface plate have more rigidity for the same depth with the absence of corrosion. The usual range available from 400 250 50 mm to 2000 1000 250 mm. Standridge granite surface plates provide an accurate reference plane for work inspection and for work layout.
