Atomizer unit

An atomizer unit of a minimal quantity lubrication system for cooling and/or lubricating a subtractive machining process between a tool and a workpiece at a machining location,

• the atomizer unit comprising a chamber assembly comprising an injection chamber and comprising an atomizer chamber, the injection chamber being connected to the atomizer chamber by a nozzle,
• the atomizer unit comprising at least one first infeed duct for feeding a first compressed air flow into the injection chamber, and at least one second infeed duct for feeding a second compressed air flow into the atomizer chamber,
• the atomizer unit comprising an injector valve for injecting a coolant and/or lubricant into the first compressed air flow in the injection region of the injection chamber,
• the atomizer unit being designed in such a manner that the first compressed air flow, from the injection chamber flows through the nozzle into the atomizer chamber and therein is atomized by the nozzle,
• the first compressed air flow being unified with the second compressed air flow in the atomizer chamber so as to form a transport flow for transporting the injected coolant and/or lubricant and being directable to the machining location,
• the atomizer unit comprising a heating which heats the coolant and/or lubricant and/or the first compressed air flow and/or the second compressed air flow and/or the transport flow.
