HHIP 6" X 8" X 2" Granite Surface Plate Grade B | Precision Measuring

• The top surface of this plate is precision ground to achieve a high degree of flatness and the accuracy is +/-.0001". It is a Grade B (Grade 1) plate.
• Granite surface plates meet or exceed Federal Specifications GGG-P-463C and it includes a certificate of inspection. (Note that these are not NIST traceable.)
• Granite plates are used for measuring the flatness and squareness of other objects, laying out parts, calibrating instruments, setting up tools, checking parallelism and perpendicularity, and measuring heights with the use of a height gage.
• They are also used as a work surface for assembling, inspecting, and marking parts. Non-magnetic and non-conductive.
• Surface plates are offered by HHIP in various sizes, with different levels of flatness and accuracy and are checked by an auto collimator for overall accuracy assurance.

• Prepare the Surface — Ensure the plate is placed on a stable, level surface. Clean the granite surface thoroughly with a dedicated surface plate cleaner and lint-free cloth to remove any dust or debris before use.
• Perform Measurements — Use the plate as a reference for measuring flatness and squareness of other objects. Place instruments like height gauges or dial indicators directly on the surface for accurate readings.
• Calibrate and Inspect — Utilize the plate for calibrating measuring instruments and setting up tools. Its stable, non-magnetic surface is ideal for inspecting parts and ensuring parallelism and perpendicularity.
• Protect When Idle — When not in use, cover the working surface with a heavy-duty vinyl or wooden cover to protect it from dust, accidental damage, and potential contamination.
