Cast iron flat plate is a flat reference tool used for workpiece inspection or marking.

According to their materials, they are divided into steel flat plates, cast iron flat plates, and rock flat plates.

According to their structure, cast iron flat plates are divided into ribbed plate and box type, while rock flat plates are divided into flange type and non flange type.

According to their purposes, they are divided into inspection plates, marking plates, and sand pressing plates.

According to their accuracy levels, the tablets are divided into 00, 0, 1, 2, and 3 levels, with level 2 and above being inspection tablets and level 3 being marking tablets.

Application of cast iron flat plate: Suitable for various inspection work and precision measurement reference planes, mainly used as reference planes in mechanical workpiece inspection and measurement, to check the dimensional accuracy or behavioral deviation of parts, and can be used for marking. It is an indispensable flat reference measuring tool in mechanical manufacturing inspection.

Cast iron flat plate material: High strength cast iron HT200-300, with a working face hardness of HB170-240. After two manual treatments (manual annealing at 600-700 degrees or natural aging for 2-3 years), the product has stable accuracy and good performance.

Cast iron flat plate specifications: 200 × 200-2000 × 4000, (special specifications can be made according to the buyer's drawings or agreed upon by both parties for production and processing) Cast iron flat plate accuracy: According to the metrological verification regulations, there are five levels: 0, 1, 2, 3, and precision planing.
