Nexvion AI on Instagram: "Inside a perfect case of high-precision machining with no margin for error. This is zero-tolerance territory — tolerances measured in microns (0.0005 mm or tighter). A CNC mill or wire EDM cuts metal atom by atom using electrical discharge or diamond-tipped tools that remove material in sub-micron layers. The workpiece sits in a climate-controlled room (temperature held to ±0.1°C) because even a 2°C shift can throw the part out of spec. Every pass is monitored by laser
