Our customer was machining 6Al4V Titanium dental implants and scrap rates increased the longer our competitors collets where in use.
This root cause was primarily result of cutting the threads in the main spindle. Chips wrapped around the finished threads before the implant was handed over to the sub spindle collet for machining of the head hex and internal thread.
Collet wear & bad parts
The unpredictable periodic clamping on the wrapped chips on the workpiece embedded chip impressions in the collet (Fig. 3) which in turn marked the next part when it was chucked on.
As a result the competitor's collet workholding lost it's chucking power from the bell mouthing in the front. By becoming out of round, parts lost their concentricity.
