A coolant filtering equipment for maintaining a constant temperature is provided to improve cutting ability and a machining accuracy and enhance durability of cutting tools by filtering a coolant discharged from a machining equipment for several times to separate effectively cut chips contained in the coolant and maintaining the temperature of a coolant to be regenerated at a proper temperature level. A coolant filtering equipment for maintaining a constant temperature comprises: a first filtering part for primarily separating cut chips contained in a recovered coolant; a storage tank for low pressure that recovers and stores the coolant; a lower pressure line side supply part for supplying the coolant into a first clean tank for middle pressure through a second filtering part, and supplying the coolant to a temperature control part as well as a low pressure line of a machining equipment; a first coolant pump(6) for supplying the coolant from the first clean tank for middle pressure to a second clean tank for middle pressure through a third filtering part; a second coolant pump(9) for supplying the coolant from the second clean tank for middle pressure to the temperature control part; a middle pressure line side supply part for supplying the coolant from the second clean tank for middle pressure to a middle pressure line of the machining equipment; an air blower(14) for supplying air into the coolant stored in the storage tank for low pressure; a water supply device(15) for supplying water into the storage tank for low pressure; level detecting parts for detecting levels of the coolant stored in the storage tank for low pressure, the first clean tank for middle pressure, and the second clean tank for middle pressure; and a control panel(17) for controlling the first to third filtering parts, controlling the temperature control part, controlling the low and middle pressure line side supply parts, and controlling operations of the air blower and the water supply device.
