cast iron surface plate

Cast Iron Surface is manufactured according to standard GB/T22095-2008 and it can be made into  rib type and box type. The material is the high-strength cast iron HT 200-HT 300.Additionally, the working surface are allowed to have V, T or U-shaped grooves, round holes, slot holes. Etc. It is often used as the baseline for all measurements to the workpiece.

铸铁平板用于工件检测或划线的平面基准器具。 铸铁平板用途比较广泛，应用于机械制造、化工、五金、航空航天、石油、汽车制造、仪器仪表制造等行业。 铸铁平板：主要用于检验工件误差的基准，检验平板/检验平台在机械制造过程中起着至关重要的作用它是每个工件出厂前检验的最基本基准工具。

Cast Iron Surface Plate can be used in many fields, such as motor assembly testing, vibration test rail, machinery manufacturing,automobiles, machine tool castings and so on.

铸铁平板保养

1、为了防止铸铁平板发生的变形，在吊装铸铁平板时，要用四根同样长度的钢丝绳同时挂住铸铁平板上得四个起重孔，将铸铁平板平稳吊装在运输工具上。

2、将铸铁平板支承点垫好、垫平，保证每个支撑点受力均匀，保证整个铸铁平板平稳。

3、铸铁平板安装时将铸铁平板板的各个支撑点用调整垫铁垫好、垫实，由专业技术人员将铸铁平板调整至合格精度。

4、铸铁平板使用时要轻拿轻放工件，不要在铸铁平板上挪动比较粗糙的工件，以免对铸铁平板工作面造成磕碰、划伤等损坏。

5、为了防止铸铁平板整体变形，使用完毕后，要将工件从铸铁平板上拿下来，避免工件长时间对铸铁平板重压造成铸铁平板的变形。

6、铸铁平板不用时要及时将工作面洗净，然后涂上一层防锈油，并用防锈纸盖上，用铸铁平板的外包装将铸铁平板盖好，以防止平时不注意造成对铸铁平板工作面的损伤。

7、铸铁平板应安装在通风、干燥的环境中，并远离热源、有腐蚀的气体、有腐蚀的液体。

8、铸铁平板按国家标准实行定期周检，检定周期根据具体情况可为6-12个月。

Maintenance of Inspection Surface Plate:

1.A surface plate is a a surface plate is a datum and should be protected against damage. The top should be frequently wiped clean from dust and other particles. When measurements are being made, a cloth should be spread on the surface plate on which small tools and gauges can be placed when not in use. When the surface plate is not in use the top should always be kept covered.

2. A Grade 0 or Grade 1 surface plate should be placed in a LOCAIION where there is a circulation of air which is under constant temperature control. The plate should be in a LOCAIION away from direct sunlight and sources of draughts which could cause a vertical gradient of temperature such that the top and underside of the surface plate are at different temperatures.

3.Stands should be located on a stable foundation. the surface plate should be supported firmly and levelled.
