Material: cast iron plate with HT200-300 casting, material ingredients when the raw material content plus ingredients as follows (%): carbon content: 3.1-3.4, manganese: 0.6-0.9, silicon: 1.5-2.0, sulfur <0.12, 0.3. Hardness> 180, secondary 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. .

Repair mold / cast iron platform The precision of the working surface is mainly flatness, and the T-groove flat working surface is the positioning criterion of the workpiece and the fixture, and there is a certain relationship with the direction of movement. In order to make the workpiece and the cast iron flat face contact are close and reliable, The maximum value of the straightness error on the table in each direction (vertical, horizontal, diagonal, radiation) is used as the flatness error of the work surface. The measurement method and the straightness of the guide rail are measured The method is basically the same, and the method can be checked by method, method, level and optical straightness.

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 accuracy grade 0 ~ 3 flat face, the diameter of less than 15mm of the sand holes allow the same material blockage, the hardness should be less than the hardness of the same material.Faceface blocked sand holes should not be more than 4 And the distance between the sand holes should not be less than 80mm.

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

5, the flat face is usually applied to use scraping process.For scraping the three-stage flat working face, the surface roughness Ra of the maximum allowable value of 5чm.

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 working surface set screw hole (or groove), the site should not be higher than the face.
