In reality, the final appearance and performance of a CNC machined component can change dramatically depending on the finishing process used. Two parts may come off the same machine with identical dimensions, yet look and feel completely different after surface treatment. Even more importantly, some finishing methods can slightly affect dimensions, surface roughness, wear resistance, and coating adhesion.

If you’ve ever had a CNC machining project go off the rails—parts that don’t fit, costs that spiral, or lead times that stretch too long—you know how frustrating it can be.
