By analyzing the cutting performance of low copper content recycled brass alloy prepared from scrap copper, influences of lead mass fraction, process parameters, and environmental conditions on the surface processing quality of the material were studied. Results revealed the following trends: as lead content increased, both surface machining cutting force and roughness values of the material initially decreased and subsequently increased. When lead content ranged from 1.5% to 2.5%, surface roughness values exhibited minimal variation, all achieving relatively ideal levels with an average Ra value of approximately 2.5 μm. Notably, when the lead content reached 2.5%, surface machining cutting force was at its lowest, measuring F=164.96 N. With lead content fixed at 2.5%, optimal cutting performance was achieved when lathe rotational speed (n) was set at 700 r/min and feed rate (f) at 0.15 μm/Z. The use of coolant cooling method significantly reduced cutting force on the surface of the material to F=139.37 N, while surface roughness decreased to R_a=2.024 μm. Compared with natural cooling, air cooling method improved surface roughness of the material during processing, reducing it from R_a=2.529 μm to R_a=2.216 μm. This study provided practical process guidance for the efficient and precise machining of extruded round bars with recycled brass, offering significant potential for applications in material development and mechanical manufacturing.

对废杂铜制备的低铜含量再生黄铜合金进行切削性能测试，研究了铅质量分数变化、工艺参数、环境条件对表面加工质量的影响。结果表明：随着铅质量分数增加，材料表面加工切削力和表面粗糙度均呈现先降低后升高的变化趋势； 当铅的质量分数为1.5%~2.5%时，加工表面粗糙度变化不大，均能达到理想值，R_a≈2.5 μm； 当铅的质量分数为2.5%时，表面加工切削力最低（F=164.96 N），且在车床转速n=700 r/min和进给量f=0.15 μm/Z的工艺条件下，可获得良好的切削性能。采用冷却液冷却方式可使材料表面加工切削力显著降低至F=139.37 N，同时表面粗糙度下降至R_a=2.024 μm； 相比自然冷却，采用空气冷却方式时，材料加工表面粗糙度有所改善，从R_a=2.529 μm降低至R_a=2.216 μm。本研究为再生黄铜高效精密加工挤压圆棒生产提供了工艺指导，在材料研发和机械制造领域具有实际应用价值。
