We have Turbo and Midbrook and the Midbrook are a bit more depenable
But you are right the biggest problem with Aluminum is the chips float, It tooks us a few years to get it right. But all I can say is Filter Filter Filter.
I acually eliminated the front drag on our Makino's all together and made a flume type system that the coolant flow takes all the chips to the side drag.
And from there its Filter Filter Filter I got 2 sets of rosedales and went to a smaller screen in the side drag. But without the rosedales my nozzel and thruspindle would clog constantly
Also keep your cooloant level a tad lower than you would normaly this helps evacuate chips better
