Main technology specification list

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)

D: 1mm/1000mm (workpiece not rotate, length :diameter 100: 1, uniform material, suitable feed speed)

Cutting tool life

Continuous cutting length 12-20m(not include special material)

And cutting tool can use 50times by The cutting tool resharpening , so the total length of cuttting can be more than 600m, good condition is more longer.
