鑄鐵平板是用于精密零件的測量和檢驗！平臺的表面技術(shù)要求。

1、工作表面不應有銹跡、劃痕、碰傷及其他影響使用的外觀(guān)缺陷。 

2、工作表面不應有砂孔、氣孔、裂紋、夾渣及縮松等鑄造缺陷。各種鑄造表面應清除型砂、且表面平整，涂漆牢固。各棱邊應修鈍。在精度等級低于“00”級的平板工作面上，對于直徑小于15mm的砂孔允許用相同的材料堵塞，其硬度應低于周?chē)牧系挠捕?。在工作面上堵塞的部位應不多于四處，其相互之間的距離應不小于80mm。 

3、相對兩個(gè)側面上，應設置有安裝手柄、吊環(huán)等吊裝設施的螺紋孔或圓柱孔。設計吊裝位置時(shí)應考慮盡量減少因吊裝而引起的變動(dòng)。

4、根據用戶(hù)要求，在板工作面上設置螺紋孔或溝槽后，這些部位不應出現高于工作面的凸起現象。 

5、應采用優(yōu)質(zhì)細顆料的灰口鑄鐵或合金鑄鐵制造。 

6、工作面的硬度應為HB 170-220。 

7、工作面應采用刮削工藝，對于“3”級平板工作面也可以采用刨削工藝，刨削工作表面的表面粗糙度按輪廓算術(shù)平均偏差Ra值應不大于5um

8、應經(jīng)過(guò)穩定性處理和去磁。 
平 面 度：可分實(shí)驗室級(Reference)、校驗級(Master)、工 具室級(Working) 三級 
平面研磨：平臺在很早的時(shí)候,人們利用三塊平臺相互匹配以產(chǎn)生真平平面。一個(gè)熟練而 又有耐心的 磨石師傅可以不藉助任何量測儀器,而僅利用三平臺相互匹配的 方式,做多次90度之旋轉, 即可產(chǎn)生令人難以相信的真平程度。 

平面度： 

1.AA級:其平面度(μm)= 1+1.6D2 (D為平臺對角線(xiàn)長(cháng)或直徑),用於高度精密 之測定之用, 常用於實(shí)驗室。 

2. A級:其平面度為AA級之兩倍誤差,常用於工具檢驗室作精密量具之檢驗之用。

3. B級:其平面度為AA級之四倍誤差,常用於工具檢驗室或在現場(chǎng)檢驗量具或劃線(xiàn)之用。

Cast iron plates are used for the measurement and inspection of precision parts! Surface technical requirements for the platform.
1. The working surface should be free of rust, scratches, bumps and other appearance defects that affect the use.
2. There should be no casting defects such as sand holes, pores, cracks, slag inclusions and shrinkage on the working surface. All kinds of casting surfaces should be cleaned of sand, and the surface is flat and the paint is firm. Each edge should be blunt. For flat work surfaces with a precision class lower than “00”, sand holes with a diameter of less than 15 mm are allowed to be blocked with the same material and their hardness should be lower than the hardness of the surrounding material. There should be no more than four places on the working surface, and the distance between them should be no less than 80mm.
3. On the opposite sides, threaded holes or cylindrical holes for lifting equipment such as handles and lifting rings should be provided. When designing the hoisting position, consideration should be given to minimizing changes due to hoisting.
4. According to the user's requirements, after the threaded holes or grooves are set on the working surface of the board, these parts should not appear convex above the working surface.
5. It should be made of gray cast iron or alloy cast iron with high quality fine particles.
6. The hardness of the working surface should be HB 170-220.
7. The working surface should adopt the scraping process. For the “3” grade flat working surface, the planing process can also be adopted. The surface roughness of the planing work surface should be no more than 5um according to the arithmetic mean deviation of the contour.
8, should be subjected to stability processing and demagnetization.
Flat degree: can be divided into laboratory level (Reference), verification level (Master), tool level (Working) level
Planar Grinding: At very early stages, people used three platforms to match each other to create a true flat plane. A skilled and patient grindstone master can create an unbelievable level of flatness without the use of any measuring instrument, but by using three platforms to match each other and doing multiple 90-degree rotations.
Flatness: 
1.AA grade: its flatness (μm) = 1+1.6D2 (D is the diagonal length or diameter of the platform), used for highly accurate measurements, often used in the laboratory.
2. Class A: The flatness is twice the error of AA grade, which is often used in the inspection of precision measuring tools in the tool inspection room.
3. Class B: The flatness is four times the error of AA level, which is often used in tool inspection room or in the field to test gage or scribing.
