Cast iron workbench | Cast iron workbench is also called cast iron flat plate and cast iron platform. It is suitable for various inspection work. It is a datum plane for accuracy measurement. It is mainly used as a datum plane in the inspection and measurement of mechanical workpieces to check the dimensional accuracy or behavioral deviation of parts. It can also be used for precise marking and is the most indispensable flat reference measuring tool in machinery manufacturing inspection. The cast iron workbench is made of high-strength cast iron, with a working surface hardness of 0.5%. After two manual treatments (artificial annealing degree - degrees or natural aging years), the product has stable accuracy and good wear resistance. The accuracy of the cast iron workbench: It is implemented in accordance with the national standard metrology and verification regulations, and is divided into six grades: , , , , , 3 and fine planing. Specifications of cast iron workbench: (Special specifications can be produced according to the buyer's drawings or produced and processed as agreed upon by both parties) Use of cast iron workbench: After wear and tear, the cast iron workbench can be re-scraped to restore its accuracy. The cast iron workbench can use the coloring method to check the flatness of parts, which has the advantages of accuracy, intuition and convenience. Pushing the watch base and workpiece on the scraped cast iron workbench is smoother and has no astringent feeling, which facilitates measurement and ensures measurement accuracy. The cast iron quality and heat treatment quality of the cast iron flat plate have a great impact on the performance of the flat plate: either the working surface is deformed due to the large residual internal stress, the accuracy cannot be maintained due to the lack of wear resistance, or the roughness with a small value cannot be obtained due to difficulty in scraping. . Therefore, when using a cast iron workbench, you must pay attention to the selection of cast iron materials, and use aging treatment and other methods to eliminate the residual stress of the cast iron flat plate.
