用于金属工件的切削加工的方法和机床
摘要：
在用于金属工件的切削加工的方法和机床中，设置有用于输送低温冷却介质（38）到第一刀具（16）的冷却装置（35）和用于输送低温冷却介质（38）到第二刀具（27）的预冷却装置（26）。第一刀具（16）夹持在第一刀具–夹具（13）中并且加工工件，其中，第一刀具（16）在加工过程中借助于低温冷却介质（38）冷却。第二刀具（27）夹持在第二刀具夹具（26）中，并且应用于后续加工工件。为此，借助于预冷却装置（36）向第二刀具（27）输送低温冷却介质（38）并因此预冷却到加工所需的运行温度。因为第二刀具（37）在刀具更换以后已经具有运行温度，可以直接继续进行工件的加工。通过基本加工时间并行地预冷却，减小了机器基本加工时间，由此机床具有更高的生产率。
摘要（英）：

In a method and a machine tool for machining metallic workpieces, a cooling device (35) for feeding a cryogenic cooling medium (38) to a first tool (16) and a pre-cooling device (36) for feeding the cryogenic cooling medium (38) to a second tool (27) are provided. The first tool (16) is held in a first tool holder (13) and machines a workpiece, the first tool (16) being cooled by the cryogenic cooling medium (38) during machining. The second tool (27) is held in a second tool holder (26) and is to be used subsequently for machining the workpiece. For this purpose the second tool (27) is fed with the cryogenic cooling medium (38) by means of the pre-cooling device (36) and thus brought to the operating temperature required for machining. Because the second tool (27) is already at the required operating temperature after a tool change, the machining of the workpiece can be continued immediately. The pre-cooling that occurs parallel to machining reduces the machine cycle time, and the machine tool thus has a higher productivity.
