PURPOSE:To enable to keep the cutting fluid at constant level and to effectively collect floating substance by a method wherein a make-up device to make up the reduced amount of the cutting fluid and a scraping device to collect the floating substance are provided in the circulating storage tank of the cutting fluid and in addition both the above-mentioned devices are operated coupled with the stopping action of the device. CONSTITUTION:When the fluid level a, which ascends at the stoppage of supply of the cutting fluid, in the storage tank 10 is lower than the detecting position of a level gage 21, make-up water is supplied through a make-up pipe 23. When the fluid level a reaches to the detecting position of the level gage 21, a guide roller 12a is caused to rotate so as to run a raking-up scraper 14 toward the direction as indicated with an arrow. Owing to the running of the scraper 14, the floating substance B on the fluid level a is collected rightward to the partition wall 15 side and in succession adsorbed with an adsorption belt 18 in order to be discharged through a scraping board 19 to a discharge tray 20. In addition, sediment C is discharged from the opening 10c of a bottom surface 10a. |
