Can You Guess the Finest Surface Finish Each CNC Process Can Achieve? Ever wondered how smooth your CNC-machined part can really get? Whether you're designing aerospace components, medical implants, or precision tools, surface roughness plays a vital role in functionality, aesthetics, and performance. 🔍 Discover the smoothest surface finishes achievable in CNC machining! From rough turning to ultra-fine mirror grinding—this infographic reveals which method delivers the sleekest results. #CNCmachining In this guide, we’ll explore the minimum achievable surface roughness across six popular CNC machining methods—and reveal which technique gets closest to a mirror-like finish. 🔧 1. CNC Turning CNC Turning is one of the most commonly used subtractive manufacturing methods, especially for cylindrical parts like shafts, pins, and bushings. The workpiece rotates, while a stationary cutting tool shapes it. Rough Turning Accuracy: IT11 Surface Roughness: Ra 20–10 μm ...
