Realize drilling efficiency 5 times and non-step drilling of L/D 20 deep hole.
Drilling deep holes requires a step process because chips are difficult to remove. On top of that, not applying cutting fluid
directly to the cutting point shortens the service life of the cutting edge and vibration may cause damage and uneven wear to the
cutting edge, which makes it difficult to increase productivity. Drilling lubrication holes for auto crankshafts is a typical example of deep drilling where using MQL Power Long Drill combined with the MQL Power Cell improves productivity fivefold.
