Frequently Asked Questions

CNC Aluminum machining is a manufacturing process that involves cutting a piece of raw Aluminum until a final desired shape or object remains. CNC machines cut unwanted geometries away from a natural block of Aluminum using a CNC (computer numerically controlled) machine tool. These machines are exact, allowing for high accuracy and part complexity.

The Cost of Aluminum CNC Machining depends on the following factors: Aluminum types, the shape of the parts(simple or complex geometries), tolerances, and part size.
STCNC will always help Minimum the cost of each Part for our customers.
