Circular flat plate application: suitable for various inspection work and measurement reference planes; Used as a benchmark for mechanical inspection and measurement of machine tools; Checking the dimensional accuracy or shape deviation of parts and making tight lines is also an essential tool in mechanical manufacturing.

Circular flat plate material and treatment: The material is cast iron HT20-40, and the working surface hardness is HB770-240. After two treatments (manual annealing at 600 ° -700 ° and natural aging for 2-8 years), the accuracy of the product has been stabilized. The materials and treatments of the following products are the same except for ductile iron.

Circular flat plate accuracy: According to the standard metrological verification regulations, it is divided into four levels: 0, 1, 2, and 3.

Daily maintenance of circular tablets:

To prevent deformation of the circular flat plate, four steel wire ropes of the same length should be used to simultaneously hang the four lifting holes on the circular flat plate during lifting, and the circular flat plate should be smoothly lifted onto the transport vehicle.

※ Place and level the support points of the circular flat plate, ensuring that each support point is evenly stressed and the entire circular flat plate is stable.

During the installation of the circular flat plate, the various support points of the circular flat plate should be padded and compacted with adjustment shims, and the technical personnel should adjust the circular flat plate to a qualified accuracy.

When using a circular tablet, handle the workpiece gently and do not move rough workpieces on the circular tablet to avoid damage such as bumps and scratches on the working surface of the circular tablet.

To prevent the overall deformation of the circular flat plate, after use, the workpiece should be removed from the circular flat plate to avoid long-term heavy pressure on the circular flat plate caused by deformation.

When the circular flat plate is not in use, the working surface should be cleaned in a timely manner, then coated with a layer of anti rust oil, and covered with anti rust paper. The outer packaging of the circular flat plate should be used to cover the circular flat plate to prevent damage to the cast iron flat plate working surface caused by carelessness.

The circular flat plate should be installed in a ventilated and dry environment, and kept away from heat sources, corrosive gases, and corrosive liquids.

Circular flat plates are subject to regular weekly inspections according to standards, and the inspection cycle may be 6-12 months depending on specific circumstances. Packaging: There are two forms of packaging: iron plate packaging and wooden packaging. The platform table is sealed with plastic film. This packaging is suitable for inland transportation of flat plates and has good measures to protect the flat plates, such as shock resistance, rust prevention, and rough handling, for transportation to the site.
