The accuracy of drilling hole
Accuracy of drilling hole: IT7-IT10 (good condition IT7-IT8; general IT9-IT10) ;
Roughness: Ra 0.4-3.2μm
Deviate of center axis:
A: 0.25mm/500mm (workpiece roate, length :diameter 100: 1, uniform material, suitable feed speed)
B: 0.5mm/1000mm (workpiece roate, length :diameter 100: 1, uniform material, suitable feed speed)
C: 0.5mm/500mm (workpiece not rotate, length :diameter 100: 1, uniform material, suitable feed speed)
