straight milling collet of lathe machine tool accessories ma

milling chuck collet
imported material SUJ2.
Precision:0.015mm,0.02mm.
Cryogenic treatment and thermal aging treatment

Inspection
1.Using itorsional spring table of 0.001mm division value;
2.The accuracy of inspection tool is 0.002mm, collet every turn 90 ° measuring once, collet turn four times ,

take a peak as the ultimate accuracy value, high precision of no more than 0.005mm for 0.005mm,

high precision of not more than 0.008mm for 0.008mm.
3.Accuracy of 0.005mm collet need to strengthen the heat aging treatment, take stable precision and

size effect, the again detection accuracy is not high than 0.005mm and then determine the accuracy of 0.005mm.
