Many years ago running my first ever program on a VMC with flood coolant, it soon became apparent how retarded it was trying to position coolant nozzles to satisfy every tool. I thought that someone needs to invent a programmable position coolant nozzle. I then learned that somebody had. (Spider Cool) There may be others.
I see a lot of inventive ideas here at coolant delivery, but every single one pales miserably compared to programmable coolant nozzle(s).
Sure it really hurts to pay the price. Especially when it comes out of your own pocket like it does for me. The ouch of 2K plus if I remember right. But that pain vanishes almost immediately once it's up and running. You will never-ever regret it.
I have both single and a twin nozzle units. I seldom need or use two nozzles at once, but it is really nice on jobs when the need is there.
Not sure of the mounting location limitations of a Brother machine, but I bet all the smart Brother owners can figure something out.
I can't imagine having just two coolant nozzles even if they are servo aimed.
That won't work in a slot or if a wall of the part blocks the flow.
My first real mill was a 1982 Mori. 40 years ago mori had this shit down. Half a dozen nozzles right around the tool, in the spindle face, spraying down at a shallow angle plus built in air nozzles.
When the nozzles spray down right around the tool, the angle is not a concern unless your tools vary more than a foot.
Programmable coolant probably looks neat until you use a machine that the mtb actually thought through. After that you realize it's just a gimmick and a bad substitute for good design.
