Q&A K
Q-1 Is it possible to use outer coolant? Drilling diameter and coolant amount
A-1
Outer coolant is not recommended because the amount of chips will be
Q-2 enormous. 60
A-2 Use internal coolant.
See the graph of “Drilling diameter and coolant amount”. 50 Drilling
What level of spindle output is required? 40
Higher output is preferable. 30
What is important is enough torque rather than high spindle rate.
See the examples of required power as below. 20 The amount of coolant is obtained by 90
measuring the coolant after it passes
10 through the drill and is discharged.

* The required power was read on the load meter.
Q-3 The workpiece material is elastic and the chips are stretched and tangled. Is there any countermeasure?
A-3
When chips of elastic material are stretched and tangled, try “low rate + large feed”, “high rate + small feed” or
: Check Availability other settings.
Chips are usually stretched well between the entrance and 10 mm inside, and not any more stretched further
inside. Therefore changing the condition of entrance only will also be effective.
[Low rate + Large feed]
This setting makes the chips thicker so that they easily break off.
E.g. Vc=80 m/min, f=0.2 to 0.25 mm/rev
