Abstract

Technical Field
[0001] This utility model belongs to the technical field of grinding devices, specifically relating to a grinding device for rotary core filling. Background Technology
[0002] In the manufacturing process of rotary cores, casting is a common pre-processing step. The rotary core blank obtained through casting requires cutting of the top gate after molding. However, current cutting processes inevitably leave some residue at the gate. If this residue is not completely removed, it can cause significant damage to the cutting tools during subsequent machining processes due to sudden increases in cutting depth. Frequent tool damage not only increases production costs but also leads to production interruptions, disrupting production plans. Furthermore, the need to replace damaged tools and readjust machining parameters further reduces production efficiency.
