Cast iron platform Applicable to all kinds of inspection, datum plane for measuring precision, used in machine tools mechanical measurement reference check size or shape and position deviations of the parts, and precision line. In machinery manufacturing is also an indispensable basic tools.

Cast iron platform Info: HT200-250 face hardness of materials for high strength cast iron HB160-210. After two treatment (artificial annealing 600 degrees----700 degrees, or natural aging 2---3 years), so that the accuracy and stability of the product, good resistance to abrasion.

Precision cast iron platform: According to the national standard metrological implement respectively 0, 1, 2, 3 to four levels.

Cast iron platform specifications : 200mmx200mm-2000mmx4000mm (Special specifications can be produced according to drawings or agreed process.

Cast iron plate Specifically applied to large equipment base levelling, reasonable design, structural stability, high precision, wear-resistant characteristics of 3000mm-6000mm Tablet mosaics can be realized, the product is made by scraping or grinding. Widely used in machining, tool shop, machine (test) repair shop, large equipment base, measuring and precision machining of test, measuring and grinding, and precise measurements, test the flatness of the workpiece, flatness and the tolerance value.

1, the platform must go through two back stress aging treatment, prevent stress memory appears distorted and platforms used in the occurrence of cracks in the future to eliminate casting stress and rough purpose of stress, strain relief up to 90%;

2, face processing acute angle obtuse;

3, casting force is not machined surface greasy, polishing, are required to paint coating on the inner surface;

4, flat face without seriously affecting the look and performance of sand, pores, cracks, inclusions, porosity, scratches, bumps, rust and other defects.

3, precision is 0 ~ 3-level on the flat face of diameter less than 15mm blockage of sand allows the use of the same materials, its hardness is less than with the hardness of surrounding materials. Sand blocking the face-hole should be no more than 4. And sand between the distance should not be less than 80mm.

4, plate shall be made of high quality fine grey cast iron or alloy materials such as cast iron, its working surface hardness should be 170~ 220HB.

5, flat working surface is usually applied using a scraping process. Skiving machining of 3 flat working surface, the surface roughness Ra of the maximum allowable value of 5 ч m.

7, flat face paint for the Institute tests should be carried out using the scraping process. Displayed after the grinding point of contact area ratio is shown in table 3 provisions or 25mmx25mm difference between points of contact shall not be more than 5 points. In case of disputes, contact area ratio as the assessment basis.

8, flat on either side, should have a threaded hole of the handle or ring equipment installed (or a cylindrical bore), and location of the device should be designed to minimize the deformation caused by the handling.

9, plate set screw hole on the face (or Groove), which parts should be no higher than the face.
