Material: cast iron plate using HT200-300 casting, material ingredients ingredients and ingredients according to the following criteria (%): carbon: 3.1-3.4, manganese: 0.6-0.9, silicon: 1.5-2.0, sulfur <0.12, phosphorus < 0.3. Hardness> 180, the second tempering treatment.

Cast iron plate It is specially designed for the flattening of large equipment with reasonable design, stable structure, high precision and abrasion resistance. It can be used for flattening from 3000mm to 6000mm. The product is made by scraping or grinding. Measurement, and grinding of machining centers, tool shops, machine shops, inspection and maintenance workshops, large-sized equipment bases, measuring chambers and precision machining, and accurate measurement and inspection of the flatness, flatness and angle tolerance of workpieces. .

Floor boring machine table technical requirements:

1, the platform must be subject to two back stress stress aging treatment, to prevent the deformation of stress memory distortion and the future use of the platform into the phenomenon of cracks in the occurrence of the elimination of casting stress, the purpose of rough stress, stress relief of 90%

2, the working face finished the acute angle blunt;

3, the casting surface to be processed without external force, polished, the inner surface are required to paint anti-rust paint;

4, flat face can not seriously affect the appearance and performance of sand holes, pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects.

3, the precision level of 0 to 3 on the flat face, the diameter of less than 15mm sand hole allows the same material to block, the hardness should be less than the same material hardness of the face of the sand hole should be no more than 4 And the distance between the sand holes should be not less than 80mm.

4, the plate should be used high-quality fine gray cast iron or alloy cast iron and other materials, the face hardness should be 170 ~ 220HB.

5, flat face is usually used in the use of scraping processing. For the use of scraping the processing level of the three flat face, the surface roughness Ra maximum allowable value of 5 ч m.

7, the flat face with the scraping process should be carried out on the color of the test. The proportion of contact area after the inquiry shown in Table 3, or 25mm × 25mm in the number of points of contact should not be greater than 5 points Controversial, according to the ratio of contact area for the assessment basis.

8, the plate relative to the two sides, there should be installed handle or ring device screw hole (or cylindrical hole), and the device location should be designed to minimize the deformation caused by handling.

9, if the flat face set on the working hole (or groove), the location should not be higher than the face.
