Flatness gauges are used for visual flatness inspection, or with the use of feeler gauges. They are divided into knife-edge, flat, and H-type. They come in various qualities (flatness accuracy) based on the DIN 874 standard. These categories are in order GG2 (lowest) GG2 - GG1 - GG0 - GG00 (highest)

Flatness Stripes
Wiki

Flatness Stripes

The straight edges (straight edges) are standard inspection tools used to verify the straightness and flatness of large surfaces. Unlike common rulers, straight edges focus on the edge accuracy of their working edge, which serves as an absolute reference guide for identifying deviations and waviness.

  • Types: They are classified into straight edges with a rectangular cross-section and knife-edge straight edges (knife-edge) for high-precision checks using the light-gap method.
  • Materials: They are made from special tool steel, cast iron, or black granite for maximum thermal stability.
  • Applications: Essential in machine grinding, machine tool assembly, and engine maintenance (cylinder head inspection).
