Removing Aluminium From a Cutter

[Neil LickfoldParticipant @neillickfold44316]

What they did at work was to have a lot of nozzles around the work head, with only 2 at a fairly high velocity, and then the others are just high volume. The Volume ones carry away the chips, and to a point, help in containing the higher velocity jets from splashing forwards, so all the junk goes to the back and out to the LH side away from the operator. It seems to work well with not only the Ali swarf control, but also the steel as well. It did require a bigger hose diameter from the pump, and is a juggle. The volume outlets have a smaller hole further back, then has a longish big diameter hose to turn it from a a jet of water to a flow of water if that makes sense.

On my cnc wood router that we cut Ali with, I have the little airblast thing aiming through a hole on the Vacuum surround . So the air oil mist gets to the cutter and lift the chips, into the direction of the vacuum thing. Keeps it reasonably tidy and swarf free around the area being cut, and the cutters last a long time, with no build up or jamming of chips.
