Hebei Beizhong manufacturer produces round flat plates suitable for various inspection tasks, serving as a reference plane for precision measurement; used as a measurement reference for machine tool mechanical inspection; checking the dimensional accuracy or form deviations of parts, and for precise marking. Cast iron round flat plates are also indispensable basic tools in mechanical manufacturing.
Specifications of round flat plates produced by Beizhong manufacturer: 500-6000mm (special specifications are made according to the buyer's drawings). Uses of round flat plates: Suitable for various inspection tasks, serving as a reference plane for precision measurement; used as a measurement reference for machine tool mechanical inspection; checking the dimensional accuracy or form deviations of parts, and for precise marking. Cast iron round flat plates are also indispensable basic tools in mechanical manufacturing.
Materials and treatment of round flat plates produced by Beizhong manufacturer: The material is high-strength cast iron HT200-300, with a work surface hardness of HB170-240. After two artificial treatments (artificial annealing at 600°C--700°C and natural aging for 2-3 years), the product achieves stable accuracy and good wear resistance. (Except for nodular cast iron, all others are the same.) Accuracy of round flat plates: Executed according to the national standard metrological verification regulations, divided into four grades: 0, 1, 2, and 3.
