The cast iron sink platform is used as a foundation platform for machine tool processing, which has the characteristics of moisture resistance, non fading, and low temperature coefficient. There are holes and T-shaped or U-shaped grooves, V-shaped grooves on the working surface. The T-shaped groove is used to fix the workpiece and clean the iron filings generated during processing, and the holes are used for oil leakage or water.

The material requirements for the cast iron sink platform are that the high-strength cast iron HT200-300 has a working face hardness of HB170-240. After two manual treatments (manual annealing at 600-700 degrees and natural aging for 2-3 years), the product has stable accuracy and good performance.

The specifications of the cast iron sink platform range from 300mm × 300mm to 3000mm × 6000mm. (Various specifications of machine tool worktables can be customized according to user requirements.) Machine tool worktable accuracy: According to the metrological verification regulations, there are four levels: 0, 1, 2, and 3.

Precautions for cast iron sink platform: Some product defects may occur during the production process, and correct methods should be used to make up for them. The main defects of cast iron platforms include air holes, sand holes, sand inclusions, shrinkage porosity, etc. There are detailed provisions for treatment in the "Machinery Industry Standard of the People's Republic of China" jb/t7974-2000. The service life of cast iron platforms is closely related to defects. So when dealing with defects in cast iron platforms, strict adherence to process requirements is necessary.
