[0002] Stainless steel castings are produced through casting technology and are made of stainless steel. This type of steel has the corrosion resistance of stainless steel and can also obtain complex shapes through casting. It is widely used in fields with special corrosion resistance requirements and structural design requirements. The equipment for grinding stainless steel castings is mainly designed to remove excess materials and burrs on the surface of castings and obtain the required surface finish. This type of equipment is usually equipped with grinding discs of different particle sizes and materials to meet different grinding needs. The grinding discs of existing stainless steel casting grinding equipment are fixedly installed and cannot be quickly disassembled and replaced after wear, which may reduce production efficiency.

In this patent solution, it grinds stainless steel cast steel parts with a grinding disc. However, the grinding disc is fixedly installed and cannot be quickly disassembled and replaced after wear. It takes more time and tools to disassemble and assemble the grinding disc, which increases downtime and reduces overall production efficiency. The complex disassembly and assembly process may lead to additional maintenance costs, including labor costs and possible repair costs. The inability to quickly replace different types of grinding discs limits the equipment's ability to adapt to different materials and different grinding requirements. Utility Model Content
