PROBLEM TO BE SOLVED: To provide a waste liquid processing device capable of surely separating machining chips such as cut chips even by a filter having a comparatively coarse mesh. SOLUTION: This machining waste liquid processing device performs processing of the machining waste liquid mixed with machining chips generated by machining in machining liquid supplied when performing machining in a machining device. The machining waste liquid processing device is provided with a waste liquid tank 2 for storing machining waste liquid, a pump 3 for feeding the machining waste liquid stored in the waste liquid tank 2, and filters 4a and 4b for filtering the machining waste liquid fed by the pump 3. Each of the filters 4a and 4b is constituted of filter paper 41 formed into a cylindrical shape, a cylindrical body 42 covering an outer periphery of the cylindrical filter 41 and provided with a plurality of openings on a side surface, a bottom plate 43 closing a lower end of the filter paper 41, and a top plate 44 closing an upper end of the filter paper 41 and provided with a waste liquid introduction port 441 for introducing the machining waste liquid fed by the pump 3. Particle powder 40 is projected into the filter paper 41. COPYRIGHT: (C)2009,JPO&INPIT
