The client faced challenges with <strong>short tool life (800 holes)<\/strong>, <strong>poor surface finish (Ra>1.6\u03bcm)<\/strong>, and <strong>costly trial failures<\/strong> from generic reamers. Through <strong>geometry optimization<\/strong> (adjusted rake\/spiral angles), <strong>material science<\/strong> (ultra-fine carbide + TaC additive), and <strong>coating innovation<\/strong> (TiAlN composite), the solution achieved <strong>1,500-hole lifespan<\/strong>, <strong>\u00b10.005mm tolerance<\/strong>, and <strong>30% efficiency gain<\/strong>. The client adopted it as a <strong>standardized process<\/strong>, saving <strong>\u00a5100,000\/year<\/strong> with <strong>200+ monthly orders<\/strong>.
