How does the steel foundry measure the size of large steel castings?
Because the size of the steel castings is very large, so when the steel foundry in the measurement of size is some difficulty, the traditional method is to use contact coordinate measuring machine, but the efficiency is relatively low, some companies will use gantry coordinate, joint arm and theodolite and other equipment to carry out 3D measurement, but these equipment also has shortcomings, That is, the measurement speed is relatively slow, which is not conducive to improving the production cycle of the mold.
In addition to checking the dimensions of steel castings, steel foundy should also quickly check the key dimensions of good castings in advance, and then input them into the processing center, so that you can determine whether the margin for subsequent processing can meet the standard, improve processing efficiency, and avoid tool damage in the processing center. In addition, we can also calculate the shrinkage coefficient of the steel castings according to the measured size of the casting to determine the more accurate processing allowance of the foam model.
In the process of casting, large steel casting products will be affected by many factors, such as the deformation of sand mold and the shrinkage deformation caused by casting molding, etc., will produce certain errors, steel casting manufacturers should pay attention to, do not think that these errors are insignificant, if the processing size is insufficient, the subsequent results are very serious, it can be seen that, How critical is the size inspection of large steel castings.
