Cast Iron Inspection Surface Plate

The cast iron inspection surface plate serves as the measuring basis, which is used for inspecting the machinery parts' geometric tolerance such as flatness, straightness, etc. Also, it can be used to the scribing, abrasive machining, equipment installation, and more. This iron inspection plate could be plate type or box type in appearance. Its precision includes Grade0, Grade1, Grade2, and Grade3.

Once the cast iron inspection surface plate is abraded, it can be scraped again to restore the precision. Additionally, you can use the coloring method to inspect the flatness, which is accurate, direct, and convenient.

Size
We can make precision surface plate that is available with the size range of 100mm×100mm to 4000mm×10,000mm. For the larger one, we can use the splicing method. In our factory, we also can make the special sized product according to your drawings or the discussion by both parties.

Remark
The quality of both cast iron and thermal treatment has a great impact on the performance of the surface plate. The working surface will deform as a result of the larger remaining inner stress. If the product is nor processed to be abrasion resistant, it can't maintain its precision after having been used for some time. Furthermore, it can not obtain the minimum roughness if the scraping is difficult.

Because of the aforesaid reasons, we should choose the proper cast iron. And use the aging treatment to eliminate the residual stress of the cast iron precision ground plate.

Inspection Method
Inspection Standard: Coloring method for inspection
1. Grade0 and Grade1 Types: within each side of 25mm2, there are at least 25 points.
2. Grade2 Type: within each side of 25 mm2, there should be at least 20 points.
3. Grade3 Type: within each side of 25 mm2, there should be at least 12 points.
