304 and 316 stainless steel are the mainstream materials for high-end sanitary hardware, but their poor thermal conductivity brings great challenges to automatic grinding. A large amount of grinding heat accumulates rapidly during processing. Excessive grinding pressure or fast feeding speed will instantly raise the surface temperature of workpieces, resulting in irreversible scorching and discoloration. For thin-walled stainless steel parts with a wall thickness of 1-2mm, thermal stress will also cause secondary deformation, leading to dimensional out-of-tolerance and direct scrapping of finished products. Heat-related defects have long been one of the top reasons for low yield in sanitary hardware grinding workshops.

To tackle the problem of heat accumulation fundamentally, DZ Intelligent Manufacturing has built a multi-level temperature control system integrating active cooling, interval heat dissipation and linkage protection. First, dedicated cooling structures are equipped on fixtures and processing stations to cool workpieces in real time during grinding and restrain heat accumulation at the source. Second, we add natural cooling procedures in the production process. Waiting links are set between working procedures to avoid continuous heat superposition.

In addition, the equipment is equipped with an intelligent linkage mechanism of overload protection and cooling system. Once abnormal load is detected during operation, the machine will automatically reduce the feeding speed and strengthen cooling synchronously. The supporting automatic sanding belt cleaning device removes metal debris regularly to prevent belt clogging. Blocked sanding belts will increase friction sharply and generate extra heat, so regular cleaning effectively avoids workpiece scorching caused by friction overheating.

Combined with high-quality ceramic alumina sanding belts, our complete temperature control and grinding process can keep the surface quality of stainless steel workpieces stable all the time, reduce the scrap rate to the minimum, and help manufacturers create high-quality sanitary hardware products.
