High-precision connector pins fail in the field for reasons a standard diameter check won’t catch.
The parting-off face – that circular cross-section left after the cutoff operation – is where burrs form first, where Ra values quietly climb out of spec, and where poor deburring technology choices create field returns nobody traces back to the machining lot.
Solving section surface finish problems starts with understanding why the end face behaves so differently from the turned barrel – and which deburring approaches are actually suited to the pin geometry. [Read more…] about Connector Pin Processing: End-Face Finish and Burr Control
