    • 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 are disclosed. The machine tool cooling system and cooling method include a hot oil tank storing hot oil, a cold oil tank storing cold oil, a first to third hot oil passages and a first to third cold oil passages, which supply the hot oil and the cold oil to a first to third heat generating portions, a hot oil return passage returning the hot oil to the hot oil tank, a first to third supply control valves interposed in the first to third cold oil passages, and a valve controller controlling opening/closing of the first to third supply control valves so that the cold oil is supplied to the first to third heat generating portions intermittently at different timings.
    • 公开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来进行成本降低,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,储存冷油的冷油罐,第一至第三热油通道和第一至第三冷油通道,其供应热油和冷油 第一至第三发热部分,将热油返回到热油箱的热油返回通道,设置在第一至第三冷油通道中的第一至第三供给控制阀,以及控制阀的开/关控制阀 第一至第三供给控制阀,使得冷油在不同的定时间歇地供给到第一至第三发热部。
