(Japanese Patent Application No. 9-254167). The present invention is to use a water-insoluble cutting oil and another aqueous solution at the same time or by switching over time, collect them in one collection tank, and then separate them based on a difference in specific gravity.

る。Means for Solving the Problems To solve the above problems,
In the method for recovering and supplying cutting oil according to the present invention,
Non-aqueous water based on farolefin or highly refined oil
During cutting using a soluble cutting oil, the aqueous solution
And water-insoluble cutting oil and aqueous solution once.
Collect and store in the collection tank, and use water-insoluble cutting oil and other aqueous solutions.
Are separated and reused at the time of cutting.
The suction port for the water-insoluble cutting oil is set upward.
It is set up and down according to the oil level . When the water-insoluble cutting oil and another aqueous solution are collected in one collection tank and reused, the water mixed in the water-insoluble cutting oil is not immediately separated due to the viscosity. However,
From the relation of the specific gravity, generally, the water mixed in the water-insoluble cutting oil decreases as the oil level increases. Therefore, in the present invention,
The suction port of the water-insoluble cutting oil was moved up and down in accordance with the oil level, so that the water-insoluble cutting oil was sucked up from a position near the oil level. That is, in the present invention, in a cutting process in which an aqueous solution is supplied to a processing location (typically, spraying or spraying) during a cutting process using a water-insoluble cutting oil, the collected liquid is collected and stored in one collection tank. When the water-insoluble cutting oil and other aqueous solutions are separated and reused, the suction port of the water-insoluble cutting oil is moved up and down in accordance with the oil level. In addition, as a method of moving the suction port up and down, there is a method of attaching a float near the suction port, and the position of the suction port may be appropriately changed according to the condition of the equipment. If the suction port is set downward, depending on the degree of separation of the water-insoluble cutting oil and the suction force of the pump, the liquid at the boundary between the water-insoluble cutting oil and the aqueous solution may be sucked. If the mouth is set upward, high-purity water-insoluble cutting oil can be reliably sucked. In the present invention, in order to separate the water-insoluble cutting oil and the other aqueous solution, it is easy to use the specific gravity difference between the two, but in addition to the method using the specific gravity difference, a water-repellent filter or a bubbling device is used. May be used. The water-repellent filter is a filter that allows only oil to pass through, and the bubbling device is
This device promotes separation of water and oil by blowing air.

性が得られる。When a water-insoluble cutting oil containing polyalphaolefin or highly refined oil as a main component is used as in the present invention, a particularly excellent effect is exhibited in the separation property from an aqueous solution. In the present invention, the highly refined oil refers to a refined oil having an aromatic component of less than 4% and a paraffin component of 65% or more. When using such a water-insoluble cutting oil, when performing cutting using the water-insoluble cutting oil while spraying or spraying the aqueous solution to the processing location, the water-insoluble cutting oil and the other aqueous solution are collected into one collection tank. Even if they are collectively stored, they can be reused with high purity because they are quickly separated. A water-insoluble cutting oil composed of a mineral oil and a low-polarity additive generally has excellent separability from an aqueous solution, but according to the study of the present inventors, as a mineral oil to be used, an aromatic component is used. It was clarified that the smaller the better, the more the paraffinic component, and the better the degree of purification by high-level solvent treatment or hydrogenation treatment to suppress unsaturated bonds as much as possible. Synthetic oils such as isoparaffins and polyalphaolefins that have no unsaturated bonds and have few impurities are included, but isoparaffins are inferior to highly refined oils, and polyalphaolefins have very good separability.

The water-repellent filter 7 allows oil to pass through but does not allow moisture to pass, so that the purity of the water-insoluble cutting oil to be reused can be further increased. FIG. 5 shows an embodiment in which the bubbling device 8 is installed in the sub tank S. The bubbling device 8 is configured such that air is blown out through a small hole, thereby promoting separation of oil and moisture.

Pumps 1 and 2 were attached thereto, and the suction port of the water pump 1 was provided at a position 5 cm from the tank bottom, and the suction port of the oil pump 2 was provided 5 cm from the oil level. Table 1 shows that the suction port of the oil pump was upward and downward, and the water content at that time was compared. The flow rates of the pumps were respectively 8 to 10 liter / min, and after operating for 30 minutes, 4 hours, and 8 hours, the amount of water in the oil was measured.

l and 200 ml of water were added, and the mixture was stirred for 30 seconds using a two-shaft hand mixer for kitchen. Regarding the separation state of the mixed liquid, the oil layer A, which is mostly oil, the intermediate layer B in which water and oil are mixed, and the water layer C are separately observed, and the boundary line L1 between the oil layer A and the intermediate layer B is observed.
And the boundary line L2 between the intermediate layer B and the water layer C were determined. The results are as shown in Table 2. The lower the position of L1, the higher the position of L2, and the closer the positions of L1 and L2, the faster the separation. For oil, the viscosity was adjusted to 9 to 11, and tap water was used as water. In the initial state, the oil level was 75 mm from the bottom surface, and the boundary between oil and water was 40 mm from the bottom surface.

In particular, polyalphaolefins and highly refined oils containing less aromatic components have excellent water separation properties. It should be noted that neutral oil (commonly known) having a relatively large amount of aromatic components is apparently excellent in water separation properties, but the turbid state was not improved even after 1 hour, and it was difficult to increase the purity due to a difference in specific gravity. .
