铸铁平台的外观质量及测量介绍

铸铁平台的外观质量及测量介绍：

适用于各种检验工作，精密测量用的基准平面，用于机床机械测量基准，检查零件的尺寸精度或形位偏差，并作精密划线。在机械制造中也是不可缺少的基本工具。按国家标准计量检定规程执行，分别为0，1，2，3级四个级别。铸铁平台在精度等级低于”00″级的平台工作面上，对于直径小于15mm的砂孔允许用相同的材料堵塞，其硬度应低于周围材料的硬度。   

在工作面上堵塞的部位应不多于四处，其相互之间的距离应不小于80mm。铸铁平台工作表面不应有砂孔、气孔、裂纹、夹渣及缩松等铸造缺陷。铸铁平台外观质量检验通常不需要破坏平台，借助于必要的量具、样块和测量仪器，用肉眼或低倍放大镜即可确定平台的外观质量状况。铸铁平台外观质量检验通常不需要破坏平台，借助于必要的量具、样块和测量仪器，用肉眼或低倍放大镜即可确定平台的外观质量状况。 

Introduction to the appearance quality and measurement of cast iron platforms:
Applicable to all kinds of inspection work, the reference plane for precision measurement, used for machine tool mechanical measurement standard, check the dimensional accuracy or shape deviation of parts, and make precise scribing. It is also an indispensable basic tool in machine building. Execute according to the national standard measurement and verification procedures, which are four levels of 0, 1, 2, and 3. The cast iron platform is allowed to be blocked with the same material for sand holes with a diameter less than 15 mm on a platform working surface with a precision level lower than "00". The 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. The working surface of the cast iron platform should not have casting defects such as sand holes, pores, cracks, slag inclusions and shrinkage. The appearance quality inspection of cast iron platforms usually does not require damage to the platform. With the necessary gages, specimens and measuring instruments, the appearance quality of the platform can be determined with the naked eye or a low magnification magnifier.
