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 […]
Why Does “Free of Burrs” Cause Rejections?
Your drawing says “Free of burrs” — and suddenly, suppliers start rejecting it or delaying quotes. What should’ve been a simple surface note turns into three extra days of silence or inflated pricing. “Free of burrs” causes rejections because it has no measurable definition. Most shops see it as unlimited manual rework risk — extra […]
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 […]
Why Does Paint Peel Off Anodized Aluminum?
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 […]
