Research on Internal Channel Polishing Technology of Multi-channel Component Based on Selective Laser Melting
Research on inner channel polishing technology is carried out to address the surface defects of multi-channel complex components formed by SLM in the aerospace field.The principles of SLM defects and abrasive flow polishing was introduced.By analyzing the characteristics of typical multi-channel components and simulating abrasive flow polishing,the polishing sequence is reasonably arranged,and the parameters are optimized with a diameter of 5～13.5 mm.By dissecting and confirming,the surface of the inner wall of the channel is smooth without hanging powder,and the surface roughness is better than Ra3.2 μm.This provides a high-quality polishing technology solution for the inner channel components manufactured by SLM in the aerospace field.
