What Info Do CNC Shops Need to Quote Fast?

You send a clean drawing, expect a quick quote, and wait days. It’s not because your part is difficult — it’s because the shop doesn’t have enough to price it confidently. CNC shops need complete RFQ data: material grade, quantity, tolerances, surface finish, and delivery deadline. When any of these are missing, estimators pause your […]
Is “Free of Burrs” Helping Your Custom Part—or Hurting Your RFQ?

You send out a drawing with a simple note: “Free of burrs.” One supplier accepts it without comment, another adds cost, and a third asks for clarification. The drawing is the same—but the RFQ results are completely different. A “free of burrs” requirement helps when it protects safety, assembly, sealing, or product performance. But when […]
What Tolerances Should I Really Use for CNC Parts?

Your supplier’s quote doubled—and all you changed were a few tighter tolerances. This happens constantly: engineers apply tight limits everywhere to “be safe,” and shops respond with inflated pricing or quiet rejections. Use tight tolerances only where fit, function, or alignment require them. For most CNC parts, ±0.05 mm is standard, while ±0.01 mm should […]

Paint peeling off anodized aluminum isn’t a minor cosmetic issue — it’s a supplier process-control failure that exposes poor coordination between anodizing and painting. If your coating lifts or flakes within months, the problem began long before the first layer of paint was sprayed. Paint peels off anodized aluminum when the oxide layer is sealed […]
