Application of cast iron circular platform: Suitable for various inspection and measurement reference planes; It is mainly used as a benchmark platform for the inspection, calibration, and calibration of circular saw discs for granite cutting tools, and can also be used as a benchmark platform for other inspection work.

Cast iron circular platform material and treatment: The material is high-strength cast iron HT250-300, with a working face hardness of HB170-240; After two treatments (manual annealing at 600 ° -700 ° C or natural aging for 2 years), the accuracy and performance of the product have been stabilized; The materials and treatments of the following products are the same except for ductile iron.

Precision of cast iron circular platform: According to the metrological verification regulations, it is divided into four levels: 0, 1, 2, and 3.

Cast iron circular platform specifications: 300-3000 (if the user requires special specifications, they can be made according to the buyer's drawings or agreed upon by both parties for production and processing).

Platform debugging method:

1. Place the platform flat on the ground, adjust the stability of the four corners by hand, and fine tune the movable feet until stable.

2. Place the tablet on the bracket and adjust its pivot position to be as close to the center symmetry as possible.

3. Adjust each foot initially to ensure even force distribution at each pivot point.

4. Use a level measuring instrument (such as a spirit level or electronic level) to check the horizontal condition of the tablet and adjust the relevant pivot points until they meet the horizontal position.

5. After the initial adjustment is qualified, let it stand for 12 hours before copying. If it is unqualified, it needs to be adjusted again. If it is qualified, it can be used.

6. After use, conduct periodic testing and maintenance based on the actual on-site environment.
