What are the challenges of machining drainage holes in stone outdoor garbage bins?

Machining drainage holes in stone outdoor garbage bins presents several significant challenges for manufacturers. The primary difficulty lies in the inherent hardness and brittleness of natural stone materials like granite or marble, which can lead to cracking or chipping during drilling operations. Tool wear is accelerated due to the abrasive nature of stone, requiring specialized diamond-tipped or carbide drill bits and frequent tool changes, increasing production costs. Achieving precise hole placement and consistent diameter is complicated by stone's natural variations in density and composition. The process generates substantial stone dust, necessitating robust dust extraction systems to maintain a safe working environment and prevent machinery damage. Furthermore, the slow drilling speeds required to prevent thermal shock and breakage reduce overall production efficiency. Manufacturers must also balance functional drainage requirements with aesthetic considerations, ensuring holes do not compromise the bin's structural integrity or visual appeal. These factors collectively contribute to higher manufacturing complexity and costs compared to processing drainage in metal or plastic bins.
