Machining Dry Is Worth A Try | Modern Machine Shop
For dry milling, horizontal-spindle machines tend to be best because they allow the chips to fall directly onto a chip conveyor under the machine. In fact, some builders have designed their latest HMCs to be open in the center to eliminate horizontal surfaces that can collect chips in the work envelope.

When near-dry milling with MQL, the tool's cutting edge works inside a mist formed from oil and compressed air, which is sprayed directly into the cutting zone. Depending on the design of a machine tool and milling cutter, the mist is delivered externally or internally through the cutter. The main function of MQL is to lubricate the cutting edge.
