For some types, we will do machining on two ends before final grinding to reach high precision, the possible runout of end surfaces can reach 0.03 mm, we grind the two ends by korean lapping machine.

Quality control system of oil pump vane rotor:

Work instruction paper and pictures at each working position

Process flow card with each tray (Fully traceability)

Sampling inspection and routing inspection

TS:16949 5 tools: PPAP, APQP, FMEA, SPC, MSA

Dimensional report as per your requirement by CMM, projector, etc
