Atomizer unit of a minimal quantity lubrication system

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

• wherein the atomizer unit comprises a chamber arrangement comprising a chamber arrangement interior, at least one first supply duct for supplying a first compressed-air stream into and through the chamber arrangement interior to a continuation duct, and an injection valve for injecting a coolant and/or lubricant into an injection region into the first compressed-air stream in the chamber arrangement interior,
• wherein the atomizer unit comprises at least one second supply duct for supplying a second compressed-air stream into and through the chamber arrangement interior to the continuation duct,
• wherein the atomizer unit is configured in such a manner that, downstream of the injection region, the second compressed-air stream combines with the first compressed-air stream and with the coolant and/or lubricant injected into the first compressed-air stream, to form a transport stream for transporting the injected coolant and/or lubricant, and wherein the transport stream is routed through the continuation duct to the machining location.
