Machine tool with air conditioned room

摘要

A processing machine installation is provided with a processing machine (11) having a tool (24) for machining a workpiece (19), heat-generating portions and non-heat-generating portions, a first cover (47) for defining a air conditioned processing machine room (57) around the processing machine (11), an air injector including a plurality of air outlet (53), provided in the first cover (47), for directing air to the respective portions of the processing machine (11), the air outlet being distributed depending on the amount of heat generated in the respective portions of the processing machine so that the air flow through the air outlet (53) portions are adjusted to substantially level the temperature of the respective portions of the processing machine an air conditioner (37) for controlling the temperature and/or flow rate of the air supplied to the air injector on the basis of the air temperature in the air conditioned processing machine room (57). The air temperature in the air conditioned processing machine room (57) is controlled to a desired temperature.
