What to Do When Mating Parts Don’t Fit After Anodizing?
Parts that passed machining inspection suddenly won’t assemble after anodizing — now your deadline is in danger and the supplier is blaming the coating. If mating parts don’t fit after anodizing, the supplier likely missed machining allowances for coating growth — even 0.01-0.03 mm per side can turn a correct press fit into interference. Keep […]
Heat Treatment Ruined Your Tolerances — Prevention and Recovery Options
Heat treatment distortion can turn an in-tolerance CNC part into scrap overnight — holes shrink or drift, faces warp, flatness disappears, and suddenly your supplier claims your drawing is the real problem. When this happens mid-project, cost, schedule, and credibility are all at risk. Most heat-treat tolerance failures can be recovered with post-heat-treat machining, CMM-guided […]

If a supplier misses their committed delivery twice and cannot show verified production progress, it’s time to line up a backup supplier. After 2–3 “one more week” delays, the problem is capability, not schedule — and […]
