1. As a benchmark for inspecting workpiece errors: The granite platform can be used to inspect workpiece errors, such as flatness, straightness and contour measurement, to ensure that the size and shape of the workpiece meet the design requirements.
2. Installation and debugging of equipment and workpieces: During the installation and debugging of mechanical equipment, the granite platform provides a stable datum to ensure accurate installation of the equipment.
3. Planar and three-dimensional scribing: In the plane and three-dimensional scribing of various parts, the granite platform provides a stable benchmark to ensure the accuracy of the scribing.
4. High-precision measurement: Due to its high accuracy and stability, the granite platform is particularly suitable for high-precision measurement work, such as the inspection of instruments, precision tools and mechanical parts.
