PRODUCT DETAILS

cast iron workshop platform is usually also called inspection platform, inspection flat plate, inspection cast iron flat plate, inspection cast iron platform.

1. Product introduction of inspection cast iron platform: The cast iron inspection platform is mainly suitable for inspection work of various products. The inspection platform is also used as a reference plane for precision measurement. The inspection platform is also used as a measurement reference for machine tool mechanical inspection. The inspection platform is used to check the dimensional accuracy or behavioral deviation of parts. The inspection platform is also a basic tool in mechanical manufacturing;

2. Specification of cast iron inspection platform: 100 * 100-4000 * 8000mm.

3. The material and treatment of the cast iron inspection platform: The material of the inspection platform is cast iron HT200-300, and the working surface hardness of the grade inspection platform is HB170-240. The grade inspection platform has undergone two manual treatments (manual annealing at 600-700 degrees and natural aging for 2-3 years), and the accuracy of the grade inspection platform is stable,

4. The cast iron inspection platform can improve the accuracy of the inspection platform: the inspection platform is executed according to the standard metrological verification regulations, which are divided into four levels: 0-level cast iron platform, 1-level inspection platform, 2-level inspection platform, and 3-level inspection platform. The inspection platform (platform) is made of reinforced plate and box type, with rectangular, square or circular working surfaces. The working surface of the inspection platform (platform) adopts scraping technology, and V-shaped, T-shaped, U-shaped grooves, circular holes, long holes, etc. can be machined on the working surface;

5. Surface quality inspection method for cast iron inspection platform: using colored hair for inspection. Level 0 and Level 1 tablets have no less than 25 points on each side within a range of 25 millimeters square, Level 2 has no less than 20 points, and Level 3 has no less than 12 points.

6. Product specification introduction of cast iron inspection platform:

100mm × 200mm --------------400mm × 400mm (this specification is applicable to inspection of flat plates), with precision levels of 0, 1, and 2.

400mm × 600mm -------1500mm × 2500mm (this specification is applicable to manual scraping and grinding platforms) with precision levels of 1, 2, and 3.

1500mm × 3000mm ---------2000mm × 3000mm (this specification is applicable to manual scraping and grinding platforms) with precision of level 2, level 3, and precision planing.

2000mm × 4000mm ---------3000mm × 10000mm/4000mm × 8000mm, with an accuracy of level 3 and precision planing.

7. The functional differences between cast iron inspection platform and marking platform:

The cast iron inspection platform is a reference plane used for measurement in production workshops or metrology departments; The marking platform is a reference plane used for marking in production.

Although both types of tablets are reference planes, their processing methods, plane accuracy, and functional functions are different.

The working surface of the inspection platform using the coloring method needs to be scraped and ground; The working surface of the inspection platform for other purposes needs to be scraped, ground or ground; Scratch the flat surface and smooth it out. From this, it can be seen that the plane of the inspection platform is on the marked flat plate.

The cast iron workshop platform serves as a reference positioning surface when detecting the flatness of workpieces using the coloring method or as an auxiliary tool for various measurements; The marking platform plays a reference role in marking work.
