What does a casting polisher do?

After the casting is poured, there will be a lot of flash on it, as well as pouring risers, which are not needed in the final product. At this time, the castings are still semi-finished, so these flash edges and gates must be removed before the products can be delivered to customers. If it is iron castings, it is usually knocked off directly with an oil hammer, and the steel castings need to be cut off by gas cutting, but a small piece will still be left on the castings after being knocked off and cut off, so it needs to be polished by a casting grinder. Generally, electric grinder is used for grinding, with a large diameter of more than 400, and there is also a small grinder in hand to grind off the redundant flash and riser on the casting a little bit, which is smooth and beautiful. This job is mainly noisy, dusty and demanding.
