Description

[0002] Metal castings are metal shaped objects obtained by various casting methods, that is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] A Chinese patent with publication number CN221696422U discloses a metal casting grinding device, including a flipping assembly, a clamping assembly and a grinder.
