[Brief explanation of the drawings]

[0007] [Figure 1] 1 is a schematic diagram of a cutting fluid manufacturing apparatus according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments as long as they do not contradict the spirit of the present invention.

[0009] (Cutting fluid or cleaning fluid) A cutting fluid or cleaning fluid according to an embodiment of the present invention contains alkaline ionized water and an additive. For example, the cutting fluid can be obtained by mixing at least one of mineral oil, synthetic oil, surfactant, and powder as an additive with alkaline ionized water and, if necessary, water. Cutting fluids are used for lubrication, cooling, and other purposes when performing machining such as cutting using machine tools. However, they can also be used for lubrication, cooling, and other purposes when grinding, in addition to cutting.

[0010] The cleaning liquid can be obtained by mixing alkaline ionized water and, if necessary, water with cleaning components such as surfactants as additives. The cleaning liquid may contain components other than surfactants as additives, such as alkaline powders such as sodium carbonate and calcium carbonate. Note that the cleaning liquid may be any liquid that has the ability to clean objects, and the objects to be cleaned are not particularly limited.

[0011] Alkaline ionized water refers to alkaline electrolyzed water produced on the cathode side by electrolyzing water or water containing dissolved salt. The alkaline ionized water may be obtained by electrolyzing water or water containing dissolved salt using a two-compartment electrolytic cell or a three-compartment electrolytic cell. The salt is not particularly limited, but is preferably, for example, sodium carbonate or potassium carbonate.

[0012] The pH of alkaline ionized water used as a raw material for producing water-soluble cutting fluid (coolant) is preferably 12 or higher, and preferably 13.2 or higher. When mixing with water or other aqueous solutions during production of cutting fluid, the pH of the resulting cutting fluid changes. The pH of cutting fluid in a machine tool coolant tank is usually preferably 9.5 to 11.0, and preferably 10.0 to 11.0. To prevent decay of the cutting fluid, the pH of the cutting fluid is preferably 9.5 or higher. When the workpiece to be machined is made of a ferrous material, the pH of the cutting fluid is preferably 10.0 or higher. By maintaining the pH of the cutting fluid at 10 or higher, the machinability of the workpiece is improved. When the workpiece to be machined is made of a non-ferrous material, the pH of the cutting fluid is preferably 9.5 to 10.0. When the pH of the cutting fluid is higher than 10, non-ferrous materials are more susceptible to corrosion.

[0013] Mineral oil is an oil containing hydrocarbon compounds derived from fossil fuels such as petroleum, natural gas, and coal. In addition to hydrocarbon compounds, it may also contain impurities derived from fossil fuels. Examples of mineral oil include aromatic hydrocarbons, paraffinic hydrocarbons, and naphthenic hydrocarbons. Examples of aromatic hydrocarbons include benzene, toluene, and xylene. Paraffinic hydrocarbons include C n H 2n+2 The naphthenic hydrocarbons are saturated chain hydrocarbons represented by the formula C, and may be straight chain or have a side chain. The number of carbon atoms is preferably 5 to 15. The naphthenic hydrocarbons are represented by the formula C n H 2n It is a saturated hydrocarbon having a cyclic structure represented by the formula:

[0014] Chemically synthesized oil is an oil agent that does not contain mineral oil and uses chemically synthesized lubricating ingredients (synthetic lubricants). A typical synthetic lubricant used is polyalkylene glycol, and because it is a synthetic product, its solubility in water can be freely designed. It is an artificially created base oil that has its molecular structure altered to suit specific purposes, such as improving "penetration," "cooling," and "lubricity."

[0015] The surfactant may be any surfactant having both a hydrophilic group and a hydrophobic group in the molecule, and any surfactant commonly used as a raw material for cutting fluids may be used. The surfactant may be a nonionic surfactant or an anionic surfactant.

[0016] The powder is not particularly limited in composition as long as it is an aggregate of solid particles, but examples thereof include alkaline powders such as sodium carbonate and potassium carbonate. The pH of the cutting fluid or cleaning fluid can be adjusted by adding alkaline powders. The powder may be supplied to the mixing tank in a dissolved or dispersed state in water.

[0017] Cutting fluids may contain emulsions, solubles, or solutions as additives, which serve as stock solutions for cutting fluids. These can be obtained by mixing these with alkaline ionized water and, if necessary, water. Emulsions are stock solutions of cutting fluids in which cutting oils such as mineral oils or synthetic oils are emulsified by surfactants and dispersed in water. Solubles are stock solutions of cutting fluids that consist of water-soluble components such as surfactants, or water-soluble components such as surfactants and cutting oils such as mineral oils or synthetic oils, and become translucent when diluted with water. Solutions are stock solutions of cutting fluids that consist of water-soluble components and become transparent when diluted with water.

[0018] The following describes the case where alkaline ionized water, additives, and water are mixed to produce a cutting fluid or a cleaning agent. When the workpiece to be machined is made of a ferrous material, it is preferable to add alkaline ionized water and water so that the pH of the cutting fluid is 10.0 to 11.0, and when the workpiece to be machined is made of a non-ferrous material, it is preferable to add alkaline ionized water and water so that the pH of the cutting fluid is 9.5 to 10.0.

[0019] When mineral oil, chemically synthesized oil, emulsion, soluble or solution is used as the stock solution for the cutting fluid, it is preferable to dilute it with alkaline ionized water and water so that the resulting cutting fluid is 1.2 to 10 parts by mass per 1 part by mass of the stock solution.

[0020] The amount of alkaline ionized water used is preferably 1 to 50 mass % based on the amount of the resulting cutting fluid.

[0021] The amount of water used is preferably 2 to 100 parts by mass in total of alkaline ionized water and water per 1 part by mass of alkaline ionized water used.

[0022] The following describes the case of producing a cutting fluid containing alkaline ionized water and a surfactant. The amount (volume) of alkaline ionized water used as a raw material is preferably such that the ratio of the volume of alkaline ionized water to the volume of cutting fluid (= (volume of alkaline ionized water) / (volume of cutting fluid)) is 1 / 5 to 1 / 100.

[0023] The cutting fluid may contain ultrafine bubbles. Ultrafine bubbles can be generated using an ultrafine bubble generator. Ultrafine bubbles are bubbles with a diameter of less than 1 μm. The diameter of the ultrafine bubbles is preferably 0.01 to 0.3 μm. The diameter of the ultrafine bubbles is preferably 0.3 μm or less, and more preferably 0.15 μm or less. In addition to ultrafine bubbles, the cutting fluid may also contain microbubbles with a diameter of less than 100 μm but 1 μm or more.

[0024] Ultrafine bubbles have a gas storage effect, and can be created with any gas depending on the application. For example, water containing ultrafine bubbles made with nitrogen gas has the effect of enhancing anti-rust properties by preventing oxidation.

[0025] The cutting fluid may contain additives other than those mentioned above depending on the desired function, as long as the function of the cutting fluid is not impaired.

[0026] (Cutting fluid manufacturing equipment or cleaning fluid manufacturing equipment) A cutting fluid manufacturing apparatus will be described below, but an apparatus having a similar configuration to the cutting fluid manufacturing apparatus described below can also be used as a cleaning fluid manufacturing apparatus. Fig. 1 is a schematic diagram of a cutting fluid manufacturing apparatus according to an embodiment of the present invention. The cutting fluid manufacturing apparatus 10 includes a supply means 1 (e.g., tap water) for supplying liquid A, a tank 2 for storing liquid B, a tank 3 for storing liquid C, an agitation tank 4 for agitating liquid A, liquid B, and / or liquid C, and a storage tank 5 for storing the cutting fluid obtained in the agitation tank 4. An ultra-fine bubble generator 6 may also be provided.

[0027] A supply path 7a is provided between the supply means 1 and the stirring tank 4, and when valve 8a is opened, liquid A supplied from the supply means 1 is supplied to the stirring tank 4 via the supply path 7a. A supply path 7b is provided between the tank 2 and the stirring tank 4, and when valve 8b is opened, liquid B in the tank 2 is supplied to the stirring tank 4 via the supply path 7b. A supply path 7c is provided between the tank 3 and the stirring tank 4, and when valve 8c is opened, liquid C in the tank 3 is supplied to the stirring tank 4 via the supply path 7c.

[0028] The cutting fluid manufacturing apparatus 10 may have a function of controlling the liquids A, B, and C supplied to the mixing tank 4 so that they total a predetermined amount at a predetermined ratio. The cutting fluid manufacturing apparatus 10 has a function of controlling the opening and closing of the valves 8a to 8c, and can control the opening and closing of the valves 8a to 8c so that the liquids A, B, and C supplied to the mixing tank 4 total a predetermined amount at a predetermined ratio. This can eliminate the need for manual labor for manufacturing and refilling the cutting fluid. Furthermore, even if the cutting fluid is repeatedly manufactured, the quality of the cutting fluid can be kept constant without significant fluctuations in characteristics such as pH and concentration.

[0029] Liquid A is water or a liquid with a kinematic viscosity similar to that of water (0.5 to 1.5 mm at 20°C). 2The liquid is not particularly limited as long as it has a pH (pH 7.0 / s), but may be, for example, tap water, industrial water, groundwater, or alkaline ionized water. The pH of the alkaline ionized water used as liquid A is not particularly limited, and is preferably, for example, 12 or higher.

[0030] Liquid B has a kinematic viscosity similar to that of water (0.5 to 1.5 mm at 20°C). 2 Liquid B is not particularly limited as long as it has the pH (pH 7.0 / s), but it may be, for example, a solution in which an additive for imparting some function to the cutting fluid is dissolved in a solvent such as water, or it may be a commercially available emulsion-type cutting fluid, or it may be alkaline ionized water. The pH of the alkaline ionized water used as Liquid B is not particularly limited, but for example, it is preferably 12 or higher, and more preferably 13 or higher.

[0031] At least one of liquid A and liquid B is alkaline ionized water, but both liquid A and liquid B may be alkaline ionized water. When both liquid A and liquid B are alkaline ionized water, they may have different pH values ​​and may contain different components.

[0032] Liquid C has a higher kinematic viscosity (for example, 1.5 to 110 mmHg at 20°C) than Liquid A and Liquid B. 2 Liquid C has a specific surface active agent (e.g., hydroxypropyl ether / s) and provides a lubricating effect to the cutting fluid. Examples of Liquid C include mineral oil and surfactants. The surfactant may be a solution diluted with a solvent such as water or a lower alcohol to increase its fluidity at room temperature.

[0033] The combination of liquid A, liquid B, and liquid C is not particularly limited. For example, liquid A may be water, liquid B may be alkaline ionized water (pH 13.2), and liquid C may be mineral oil, or liquid A may be alkaline ionized water (pH 12.5), and liquid B may be a solution (with a kinematic viscosity of 0.5 to 1.5 mm at 20°C) in which an additive is dissolved in a solvent such as water. 2 / s), and when liquid C is a surfactant solution.

[0034] When producing a cutting fluid consisting of Liquid A, Liquid B, and Liquid C, valves 8a to 8c are opened and a predetermined amount of each liquid is supplied to the stirring tank 4, but for example, only valves 8a and 8b can be opened to produce a cutting fluid consisting of Liquid A and Liquid B. Also, for example, by opening only valves 8b and 8c, a cutting fluid consisting of Liquid B and Liquid C can be produced, and by opening only valves 8a and 8c, a cutting fluid consisting of Liquid A and Liquid C can be produced.

[0035] Even when a cutting fluid is obtained by mixing two liquids instead of three liquids as described above, the ultrafine bubbles described below can be introduced into the cutting fluid. For example, when mixing alkaline ionized water with water, by using the ultrafine bubble generator 6, ultrafine bubbles can be introduced into the cutting fluid and the stirring effect of stirring the water and alkaline ionized water can be obtained.

[0036] The introduction of ultrafine bubbles into cutting fluid will now be described. Ultrafine bubbles may be introduced before, during, or after stirring of the liquid in the mixing tank 4. Ultrafine bubbles can be added to the mixed liquid of Liquids A to C before or during stirring, or to the cutting fluid obtained by thoroughly stirring these liquids. At least a portion of the mixed liquid or cutting fluid in the mixing tank 4 is supplied to the ultrafine bubble generator 6 via supply lines 7d and 7e. With valve 8f closed and valves 8d and 8e open, pump 9a is driven to send the mixed liquid or cutting fluid from the mixing tank 4 to the ultrafine bubble generator 6. The mixed liquid or cutting fluid to which ultrafine bubbles have been added by the ultrafine bubble generator 6 is returned to the mixing tank 4. By repeating this process, ultrafine bubbles can be introduced throughout the mixed liquid or cutting fluid in the mixing tank 4. The operating time of the ultrafine bubble generator 6 can be adjusted as needed. Furthermore, by returning the mixed liquid that has passed through the ultra-fine bubble generator 6 to the stirring tank 4 in this manner, the mixed liquid can also be stirred effectively.

[0037] Furthermore, without driving the ultra-fine bubble generator 6, at least a part of the mixed liquid or cutting fluid in the stirring tank 4 can be sent out of the stirring tank 4 via the supply paths 7d and 7e and then circulated back into the stirring tank 4, thereby achieving the effect of stirring Liquids A to C and generating fine bubbles in the resulting cutting fluid.

[0038] For example, when a mixture of 18.24 L of water, 0.76 L of alkaline ionized water (pH 13.2), and 1 L of emulsion cutting fluid (emulsion particles with a volume average particle diameter of 150 μm) was circulated through an ultra-fine bubble generator (flow rate: 12 L / min (at 0.3 MPa), pressure: 0.2-0.3 MPa) for 3 minutes, ultra-fine bubbles with a volume average particle diameter of approximately 0.10 μm were observed. Furthermore, when the ultra-fine bubble generator was not operated and the other conditions were the same, the mixture was sent out of the mixing vessel 4 via supply lines 7d and 7e and then circulated back into the mixing vessel 4, and fine bubbles with a volume average particle diameter of approximately 0.12 μm were generated.

[0039] When the mixing in the mixing tank 4 is completed, the valve 8f is opened and the pump 9a is driven to supply the cutting fluid obtained in the mixing tank 4 through the supply path 7f to the storage tank 5. At this time, the valve 8e is closed.

[0040] The cutting fluid stored in the storage tank 5 is supplied to the coolant tanks 21a-21a of the machine tools 20a-20c via the supply path 7g by opening the valves 8g and 8h and driving the pump 9b. The cutting fluid may be supplied to the coolant tanks automatically depending on the amount of cutting fluid remaining in the coolant tanks. The storage tank 5 is connected to a plurality of machine tools 20a-20c, and it is possible to select any one of these machine tools 20a-20c to supply cutting fluid to.

[0041] Cutting fluid can be produced by supplying water to an agitation tank, supplying alkaline ionized water to the agitation tank, and supplying mineral oil, synthetic oil, and / or surfactant to the agitation tank, and then stirring the supplied water, alkaline ionized water, mineral oil, synthetic oil, and / or surfactant in the agitation tank. The production time of cutting fluid can be shortened by generating ultrafine bubbles in a mixture containing supplied water, alkaline ionized water, mineral oil, and / or surfactant, or in a cutting fluid obtained by agitation with an agitation device. Furthermore, generating ultrafine bubbles in a mixture containing supplied water, alkaline ionized water, mineral oil, and / or surfactant, or in a cutting fluid obtained by agitation with an agitation device can improve the cooling effect of tools during cutting. Alkaline ionized water has a high cooling effect, and when cutting with a cutting fluid containing alkaline ionized water for approximately two hours, the tool temperature can be kept approximately 50 degrees lower than when a cutting fluid containing water instead of alkaline ionized water is used. Furthermore, different cutting fluids can be produced by performing only two of the following: supplying water, supplying alkaline ionized water, and supplying mineral oil and / or surfactants. The cutting fluid obtained by stirring can be supplied to a storage tank, and the cutting fluid stored in the storage tank can be supplied to a machine tool.

[0042] The cooling effect of alkaline ionized water was confirmed by the following experiment. A stainless steel plate (150 mm x 100 mm x 10 mm) with a thermocouple attached to the center was heated in a constant temperature bath at 350°C, then removed. A test liquid was poured at a constant rate toward the thermocouple to rapidly cool it, and the temperature change of the thermocouple was measured. When water was poured as the test liquid, the temperature of the thermocouple dropped by 110°C after about 2 seconds, but when alkaline ionized water was poured as the test liquid, the temperature of the thermocouple dropped by 200°C after about 2 seconds.

[0043] Liquid C has a higher dynamic viscosity than Liquid A and Liquid B and provides a lubricating effect to the cutting fluid. When at least one of Liquid A and Liquid B is alkaline ionized water, Liquid A can be supplied to a stirring tank, Liquid B can be supplied to a stirring tank, and Liquid C can be supplied to a stirring tank, and the supplied Liquid A, Liquid B, and / or Liquid C can be stirred in the stirring tank, thereby obtaining a cleaning fluid or cutting fluid containing alkaline ionized water by mixing three different liquids.

[0044] By creating a cleaning fluid or cutting fluid containing alkaline ionized water and additives, oxidation of the cleaning fluid or cutting fluid can be prevented and the proliferation of anaerobic bacteria and the like can be suppressed. This reduces the risk of putrid odors and putrefaction, thereby reducing the amount of waste fluid generated when changing the cleaning fluid or cutting fluid. The use of alkaline ionized water extends the life of the cutting fluid by preventing putrefaction, and also reduces the labor required for tool replacement and flushing. The use of alkaline ionized water improves the drainage of cutting fluid adhering to workpieces and chips, resulting in a reduction in the amount of waste fluid. Adding ultrafine bubbles to the cutting fluid can shorten the production time of the cutting fluid and improve the cooling effect of tools during cutting. [Explanation of symbols]
