DD703
Mainly used for processing unmanageable deep pinhole such as threading hole,
drilling hole on ultra-hard conducting material for wire cutting on, nozzle opening of oil pump,
spinneret orifice of spinning die, oil way of hydropneumatic components and cooling hole of engine.
1.Drilling diameter from 0.3mm to 3mm. The maximum depth ratio could be 300:1.
2.Auto deep control, blind hole can also be maken.
3.Precision ( hole straightness) is less than 0.04 mm.
4.Can drill on oblique and curved surface directly.
5.Digital readout 3 axis (X, Y, Z).
6.Fast processing speed and low consumption.
7.Can use water as coolant, low cost and no pollution.
