Carbatec Black Granite Surface Plate

This Black Granite Surface Plate provides an accurate reference for measuring objects for flatness and squareness, making it ideal for lapping tools or checking set-ups on small engineering projects. By affixing wet and dry paper to the surface, it can also be used as a large sharpening stone. Each plate is supplied with its own surface flatness test report and is packed in a wooden shipping case for safe transport and storage.

The specifications of the surface plate include approximate dimensions of 300 x 230 x 50mm, with a maximum flatness error rated at 2 microns (0.002mm) and a weight of 13.2kg.

Benefits of Black Granite include being harder than steel, resistant to rust and corrosion, and less affected by humidity or temperature changes. It retains accuracy for years, has low water absorption, and is durable under consistent use. To ensure longevity, it is recommended to rotate the surface plate periodically to prevent wearing down the same area. It is also important to keep both the surface plate and tools clean and free from grit or dust, and to avoid dropping items onto the plate, as this can chip its surface.
