(57) [Summary] [Structure] When confirming the properties of the processing oil in use,
The relationship between the viscosity of the unused processing oil and the temperature is obtained in advance, and the allowable viscosity range of the processing oil that does not cause processing defects is obtained. Measure the viscosity and temperature of the processing oil after the lapse of a predetermined time from the start of use, determine the difference between the measured viscosity and the viscosity of the unused processing oil at the measurement temperature, and determine whether this difference is within the allowable viscosity range above. To find out. [Effect] Since the property of the working oil in use can be confirmed, if the working oil deteriorates unexpectedly for some reason and the viscosity of the working oil deviates from the allowable viscosity range within the service life. You can also check this. Therefore, by responding to such deterioration and quickly returning the viscosity of the processing oil to the above-mentioned allowable viscosity range, it is possible to prevent processing defects from occurring in the processed product.

The use of each processing oil was to be completed by the end of its service life.

I remember it as (A). Further, the computing unit (2) stores a reference temperature (S), for example, an allowable viscosity range (T) at which rolling defects do not occur at 40 ° C. Then, the computing unit (2) translates the first curve (A) in the Y-axis direction and translates the detected temperature (P) and the detected viscosity (Q) output from the detector (1) after translation. The second curve shows the relationship between the viscosity of rolling oil and the temperature after a predetermined time has passed from the start of use after being placed on the first curve (A).

The viscosity (Q1) of the rolling oil after the lapse of a predetermined time from the start of use in Fig. 1 was calculated, and this viscosity (Q1) and the first curve (A)
The viscosity difference (Q3) from the viscosity (Q2) at the reference temperature (S) (40 ° C) above is obtained. Then, it is checked whether or not the viscosity difference (Q3) is within the allowable viscosity range (T), the properties of the rolling oil at that time are confirmed, and the confirmation result is output. The calculator (2) also outputs the measured temperature (P) and measured viscosity (Q) values. With this output, the measured values of temperature and viscosity and the above-mentioned confirmation result are displayed on a display device (not shown). Since the allowable viscosity range (T) is the same at temperatures other than the reference temperature (S), the viscosity difference (Q3) is the same at other temperatures.
