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 />
