When the washing is repeated, the water in the undried water-soluble cutting oil is brought in, so that the amount of water gradually increases,
The surfactant in the cleaning oil may be discharged together with water, and the performance of the cleaning oil may deteriorate. As for the state, the liquid in the reserve tank 2 is sampled to see the separated state of water and cleaning oil, or the circulation of the cleaning liquid is paused for a short time to check the layered separated state of water and cleaning oil in the reserve tank. The quality of the water is judged by looking at the liquid indicator 21. When the cleaning solution is healthy,
When the cleaning liquid is left stationary, the liquid separates into two layers by positioning water in the lower layer and cleaning oil in the upper layer, but when the cleaning liquid deteriorates, a white turbid layer is formed between them, and when the deterioration further progresses Since it becomes cloudy, the performance state of the cleaning liquid can be known. If the surfactant in the cleaning oil is discharged together with water, the above-mentioned white turbidity occurs. At that time, the air valve 16,
38 is opened and the circulation pump 14 is operated to replenish the cleaning tank 1 with new cleaning oil.
