Surface Plates

A surface plate is the flat reference for measuring and marking out in the workshop and inspection room. KNUTH supplies precision surface plates in black granite in three sizes: 400 x 250 x 70 mm, 630 x 400 x 100 mm and 1,000 x 630 x 150 mm, with a flatness of 6 to 9 µm depending on size. With optional accessories they are used to check flatness, squareness, parallelism and roundness.
