OP90精磨外圆检测手段：三坐标 ， 0-25数显千分尺检测频次：各1

OP90 precision grinding external circle <br>inspection method: three coordinates, 0-25 digital micrometer <br>Inspection frequency: each 1 piece/first, middle and last/shift, 4 pieces/each shift, 100%/each shift <br>Control means: three self-three inspection records, Process inspection record SPC, process random inspection does not record

OP90 finely grinds the outer circle<br>Detection means: three coordinates, 0-25 numbers show a microse d'scale<br>Frequency of detection: 1 piece / first middle end / class, 4 pieces / class, 100% / class<br>Control means: three self-inspection records, process inspection records SPC, process sampling records
