鑄鐵平臺(tái)的外觀質(zhì)量及測量介紹

鑄鐵平臺(tái)的外觀質(zhì)量及測量介紹：

適用于各種檢驗(yàn)工作，精密測量用的基準(zhǔn)平面，用于機(jī)床機(jī)械測量基準(zhǔn)，檢查零件的尺寸精度或形位偏差，并作精密劃線。在機(jī)械制造中也是不可缺少的基本工具。按國家標(biāo)準(zhǔn)計(jì)量檢定規(guī)程執(zhí)行，分別為0，1，2，3級(jí)四個(gè)級(jí)別。鑄鐵平臺(tái)在精度等級(jí)低于”00″級(jí)的平臺(tái)工作面上，對(duì)于直徑小于15mm的砂孔允許用相同的材料堵塞，其硬度應(yīng)低于周圍材料的硬度。   

在工作面上堵塞的部位應(yīng)不多于四處，其相互之間的距離應(yīng)不小于80mm。鑄鐵平臺(tái)工作表面不應(yīng)有砂孔、氣孔、裂紋、夾渣及縮松等鑄造缺陷。鑄鐵平臺(tái)外觀質(zhì)量檢驗(yàn)通常不需要破壞平臺(tái)，借助于必要的量具、樣塊和測量儀器，用肉眼或低倍放大鏡即可確定平臺(tái)的外觀質(zhì)量狀況。鑄鐵平臺(tái)外觀質(zhì)量檢驗(yàn)通常不需要破壞平臺(tái)，借助于必要的量具、樣塊和測量儀器，用肉眼或低倍放大鏡即可確定平臺(tái)的外觀質(zhì)量狀況。 

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.
