鑄鐵平臺的外觀(guān)質(zhì)量及測量介紹：
適用于各種檢驗工作，精密測量用的基準平面，用于機床機械測量基準，檢查零件的尺寸精度或形位偏差，并作精密劃線(xiàn)。在機械制造中也是不可缺少的基本工具。按國家標準計量檢定規程執行，分別為0，1，2，3級四個(gè)級別。鑄鐵平臺在精度等級低于”00″級的平臺工作面上，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)牧系挠捕取?
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。鑄鐵平臺工作表面不應有砂孔、氣孔、裂紋、夾渣及縮松等鑄造缺陷。鑄鐵平臺外觀(guān)質(zhì)量檢驗通常不需要破壞平臺，借助于必要的量具、樣塊和測量?jì)x器，用肉眼或低倍放大鏡即可確定平臺的外觀(guān)質(zhì)量狀況。鑄鐵平臺外觀(guān)質(zhì)量檢驗通常不需要破壞平臺，借助于必要的量具、樣塊和測量?jì)x器，用肉眼或低倍放大鏡即可確定平臺的外觀(guān)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.
