The quality of machine tool castings can not only be seen from the appearance of machine tool castings, but also the quality of machine tool castings can be seen by observing the shape and color of iron cutting during processing. The hardness of castings can also be seen through processing. After processing, the smoothness of the processed surface, the presence of pores, sand holes, shrinkage porosity, sand inclusion, etc. can be seen.

In order to ensure the casting quality of the front of the machine tool casting, the front of the casting is usually downward and the bottom is upward. If brown spots are found after processing, it can be determined that these spots are caused by the floating of the carburant during the pouring process, indicating that the quality of the carburant is poor and the carburant with better quality needs to be replaced.
After processing, if there are regular small shrinkage, or small shrinkage with shape. According to the shrinkage position, it can be checked whether the back of the gray iron casting is designed with reinforcing rib layout or link rib plate. If there is, it can be explained that the shrinkage of the processing surface of the gray iron casting during the cooling process is supplemented with reinforcing ribs or connecting rib plates, resulting in such shrinkage phenomenon.
