Usually , if very easy CNC tuning or milling parts , sheet metal parts , we will charge 40-50usd .
if some difficult products or high precision parts , we will calculate the machining time then get a machining cost , for our factory , the cost also lower than other factory .
for our facotry , we can do 0.01mm tolerance , so we have no problemd for high precision parts .
If you also have prototype or big production need do ,welcome contact us get a competitive price . thanks .
