Abstract: The invention relates to an atomizer unit of a minimal quantity lubrication system (3) for cooling and/or lubricating a chip-removing machining process between a tool (5) and a workpiece (6) at a machining station, wherein the atomizer unit (2) has a chamber arrangement (8) with a chamber arrangement interior (9), at least one first supply duct (10) for supplying a first compressed air stream (11) into and through the chamber arrangement interior (9) to a continuation duct (12) and an injection valve (13) for injecting a coolant and/or lubricant (4) into an injection region (14) into the first compressed air stream (11) in the chamber arrangement interior (9). It is proposed that the atomizer unit (2) has at least one second supply duct (15) for supplying a second compressed air stream (16) into and through the chamber arrangement interior (9) to the continuation duct (12), wherein the atomizer unit (2) is configured such that the second compressed air stream (16) joins the first compressed air stream (11), and any coolant and/or lubricant (4) injected into the first compressed air stream (11), downstream of the injection region (14) to form a transport stream (17) for transporting the injected coolant and/or lubricant (4), and wherein the transport stream (17) is conveyed through the continuation duct (12) to the machining station (7).

Abstract: An atomizer unit of a lubrication system has a chamber arrangement having 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. The atomizer unit has at least one second supply duct for supplying a second compressed-air stream into and through the chamber arrangement interior to the continuation duct. The atomizer unit is designed in such a manner that the second compressed-air stream combines with the first compressed-air stream and with the coolant and/or lubricant possibly injected into the first compressed-air stream, to form a transport stream for transporting the injected coolant and/or lubricant, and the transport stream is routed through the continuation duct to the machining location.

Abstract: Embodiments relate to an atomizer unit that has a chamber assembly with an injection chamber and an atomizer chamber. The injection chamber is connected to the atomizer chamber by a nozzle, and the atomizer unit has a first feed channel for feeding a first compressed air flow into the injection chamber, a second feed channel for feeding a second compressed air flow into the atomizer chamber, and an injection valve for injecting a coolant and/or lubricant into the first compressed air flow in the injection region of the injection chamber. The first compressed air flow flows from the injection chamber into the atomizer chamber through the nozzle, is atomized in the atomizer chamber by the nozzle, is combined with the second compressed air flow in the atomizer chamber in order to form a transport flow for transporting the injected coolant and/or lubricant, and can be conducted to the machining location.

Abstract: The invention relates to an atomizer unit of a minimal quantity lubricant system (2) for a cooling and/or lubricating function of a cutting-machining process. The atomizer unit (3) has a chamber assembly (8) with an injection chamber (9) and an atomizer chamber (10), wherein the injection chamber (9) is connected to the atomizer chamber (10) by a nozzle (11), and the atomizer unit (3) has at least one first feed channel (12) for feeding a first compressed air flow (13) into the injection chamber (9), at least one second feed channel (14) for feeding a second compressed air flow (15) into the atomizer chamber (10), and an injection valve (16) for injecting a coolant and/or lubricant (4) into the first compressed air flow (13) in the injection region (17) of the injection chamber (9). The atomizer unit (3) is designed such that the first compressed air flow (13) flows from the injection chamber (9) into the atomizer chamber (10) through the nozzle (11), is atomized in the atomizer chamber by the nozzle (11), is combined with the second compressed air flow (15) in the atomizer chamber (10) in order to form a transport flow (18) for transporting the injected coolant and/or lubricant (4), and can be conducted to the machining location (7). The atomizer unit (3) has a heater (20) which heats the coolant and/or lubricant (4), the first compressed air flow (13), the second compressed air flow (15), and/or the transport flow (18).
