The cast iron floor bed plate can be used to inspect the flatness of the parts by the coloring method, which has the advantages of accuracy, intuitiveness and convenience. Pushing the watch seat on the cast iron flat plate that has been scraped and the workpiece is smoother, without any astringency, and can be accurately measured.

The quality and heat treatment of the cast iron floor bed plate have a greater impact on the performance of the slab: or the working surface is deformed due to large residual internal stress; or the accuracy cannot be maintained; or the roughness is large due to difficulty in scraping.

 

The cast iron plate is manufactured according to the GB/4986-85 standard. The product is made of ribbed plate type and box type. The working surface is rectangular, which adopts the scraping process and can be processed with V and T shapes. , U-shaped groove, round hole, long hole, etc. The material is gray iron HT200-300, which should be made of fine grey cast iron and other materials, and the hardness of the working surface should be 170~220HB. In order to prolong the service life and accuracy of the cast iron plate. The quality of scratching contact spots is an important technical indicator of cast iron slabs.

 

The plate installation should be adjusted to the level, the load should be distributed on each fulcrum, and vibration should be avoided when using at ambient temperature. The cast iron slab has a precision grade of 0, 1, 2, 3, and fine planing. The cast iron floor bed plate is made of ribbed and box-shaped, and the working surface is rectangular, square or round.

 

Cast iron floor bed plates are widely used in various industries such as machine tools, technology, automobiles, motors, and shipbuilding. The cast iron plate is a plane reference instrument used for workpiece detection or scribing, or to detect the dimensional accuracy or behavior deviation of precision parts, and make precision scribing.
