• Made of black granite with fine particles so there are no burrs and protrusions.
• The structure is dense, the material is uniform, and there is no distortion, which will not affect the workpiece.
• Non-magnetic; non-conductive; 100% anti-corrosion.
• Due to the fine crystal structure of the granite, no sticking property, no burrs or surface bulging, it ensures long-term use and high flatness.
Features are often used as an aid in the detection of flat and machine tables.
It can also be used in lifting work above the flat plate to quickly and easily detect workpieces with shoulders or steps.
The granite flat ruler provides a good economical solution for accurate detection of parallelism and straightness measurement on CNC machines and coordinate measuring systems.
