    • There are provided a machine tool cooling system and cooling method which allow cost reduction by reducing the number of control valves, and in which opening/closing control is simple. The machine tool cooling system and cooling method include a hot oil tank 4 storing hot oil, a cold oil tank 5 storing cold oil, a first to third hot oil passages 9a to 9c and a first to third cold oil passages 10a to 10c, which supply the hot oil and the cold oil to a first to third heat generating portions 1 to 3, a hot oil return passage 11 returning the hot oil to the hot oil tank 4, a first to third supply control valves 16a to 16c interposed in the first to third cold oil passages 10a to 10c, and a valve controller 8 controlling opening/closing of the first to third supply control valves 16a to 16c so that the cold oil is supplied to the first to third heat generating portions 1 to 3 intermittently at different timings.
    • 提供了一种机床冷却系统和冷却方法,其通过减少控制阀的数量而降低成本,并且其中开/关控制简单。 机床冷却系统和冷却方法包括储存热油的热油箱4,储存冷油的冷油罐5,第一至第三热油通道9a至9c和第一至第三冷油通道10a至10c,其中 将热油和冷油供给到第一至第三发热部1至3,将热油返回到热油箱4的热油返回通道11,插入到热油箱4中的第一至第三供给控制阀16a至16c 第一至第三冷油通道10a至10c,以及控制第一至第三供给控制阀16a至16c的打开/关闭的阀控制器8,以使冷油间歇地供应至第一至第三发热部1至3 不同的时间
