What are the mechanical processing requirements for a standard cast iron platform

1. The cast iron platform should undergo stability and demagnetization treatment.

2. The cast iron platform is installed and secured with anchor rods, and the spacing is set according to the dimension markings on the machining drawing.

3. Castings should undergo secondary aging treatment, including one manual aging treatment after rough forming and one natural aging treatment after rough planing, and should not deform after long-term use.

4. The small tensile strength value measured based on the standard tensile specimen processed from a single casting test rod with a diameter of Φ 30mm must meet the requirements of the national standard.

Mechanical processing is carried out according to the drawings and technical requirements of the cast iron platform, and the products strictly meet the requirements of the drawings. The processing unit provides inspection reports on the actual dimensions, form and position tolerances, and roughness of the processed surface of the product. If there is a possibility of exceeding the tolerance during the processing, Jin Kuan will truthfully report the actual deviation and provide a solution.

The working surface requires the application of anti rust oil, and non processed surfaces require the application of anti rust paint, which must be firmly applied.

Technical requirements for cast iron platforms:

1. The cast iron platform can be inspected for flatness of parts using the coloring method, which has the advantages of accuracy, intuitiveness, and convenience. Pushing the gauge seat and workpiece smoothly on the scraped cast iron platform without any feeling of roughness, facilitates measurement.

2. The quality of cast iron and heat treatment on the cast iron platform can have a significant impact on the use of flat plates, or the working surface may deform due to residual large internal stresses; Or the accuracy cannot be maintained due to the lack of damage; Or due to difficulty in scraping, roughness with small values cannot be obtained. Therefore, when using a cast iron platform, attention should be paid to the selection of cast iron materials and the treatment of residual stresses in the cast iron platform.

3. The working face of the cast iron platform shall not have defects such as sand holes, air holes, cracks, slag inclusions, shrinkage porosity, scratches, bumps, embroidery points, etc. that seriously affect the appearance and performance.
