Poor<br />
Coolant volume is weak<br />
and too high. The coolant<br />
is not aimed into the<br />
cutting zone, which limits<br />
its effectiveness in flushing<br />
the chips, lubricating and<br />
cooling at the point of cut.<br />
Good<br />
This example of coolant placement shows<br />
plenty of flush at the end mill. The three<br />
spray nozzles are pointing down at the end<br />
mill, forcing the chips up and out of the<br />
cutting zone.<br />
Poor<br />
There is not enough coolant<br />
volume to adequately flush<br />
chips out of the cutting<br />
zone. This condition will<br />
result in re-cutting of chips<br />
and premature tool wear.<br />
Best<br />
The best coolant flush for evacuating chips<br />
from a pocket uses a coolant flush-type collet<br />
and through-spindle coolant (if your machine<br />
is equipped with it). Coolant is forced all<br />
around the end mill – 360° – at high pressure.<br />
High-pressure coolant hits the bottom of the<br />
cut and lifts the chips out and away from the<br />
cutting zone quickly and efficiently.<br />
