Exploration of casting processing technology
There are many types of castings. With the improvement of the level of casting technology, it has become possible to directly obtain high-precision workpieces using precision casting technology. However, considering the factors such as production cost, casting is mainly used as a roughing method in the manufacturing industry. Most castings are machined to the finished part. In general, the dimensional accuracy of castings is not high, so it is not only necessary but also of great practical significance to analyze how to process the final casting into a qualified finished product. The following is a commonly used sand casting machine tool
