[Brief description 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 PREFERRED EMBODIMENTS

[0008] Hereinafter, the embodiments of the present invention will be described, however, the present invention is not limited to the following embodiments as long as they are within the scope of the present invention.

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

[0010] The cleaning liquid can be obtained by mixing a cleaning component such as an additive, for example, a surfactant, with alkaline ionized water and, if necessary, with water. The cleaning liquid may contain a component other than the surfactant as an additive, for example, an alkaline powder such as sodium carbonate or calcium carbonate. Note that the cleaning liquid may be any liquid that has the effect of cleaning an object, and the object to be cleaned is not particularly limited.

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

[0012] The pH of the alkaline ionized water used as a raw material for producing a water-soluble cutting fluid (coolant fluid) is preferably 12 or more, and more preferably 13.2 or more. When mixing with water or other aqueous solutions during production of the cutting fluid, the pH of the resulting cutting fluid changes. The pH of the cutting fluid in the coolant tank of the machine tool is usually preferably 9.5 to 11.0, and more preferably 10.0 to 11.0. In order to suppress putrefaction of the cutting fluid, the pH of the cutting fluid is preferably 9.5 or more. When the workpiece to be processed is made of a ferrous material, the pH of the cutting fluid is preferably 10.0 or more. By setting the pH of the cutting fluid to 10 or more, the machinability of the workpiece is improved. When the workpiece to be processed 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 greater than 10, corrosion of the non-ferrous material is likely to occur.

[0013] Mineral oils are oils that contain hydrocarbon compounds derived from fossil fuels such as petroleum, natural gas, and coal. In addition to the hydrocarbon compounds, they may also contain impurities derived from fossil fuels. Examples of mineral oils include aromatic hydrocarbons, paraffinic hydrocarbons, and naphthenic hydrocarbons. Examples of aromatic hydrocarbons include benzene, toluene, and xylene. Paraffinic hydrocarbons are C n H 2n+2 The naphthenic hydrocarbon is a chain-type saturated hydrocarbon represented by the formula: n H 2n It is a saturated hydrocarbon having a cyclic structure represented by the formula:

[0014] Chemically synthesized oils are oils that do not contain mineral oil and use chemically synthesized lubricating components (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 changes the molecular structure to suit the purpose, such as improving "permeability," "cooling ability," and "lubricity."

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

[0016] The composition of the powder is not particularly limited 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 state where it is dissolved or dispersed in water.

[0017] The cutting fluid may contain an emulsion, soluble or solution as an additive, which is the stock solution of the cutting fluid, and can be obtained by mixing these with alkaline ionized water and, if necessary, water. An emulsion is a stock solution of cutting fluid in which cutting oil such as mineral oil or chemically synthetic oil is emulsified by a surfactant and dispersed in water. A soluble is a stock solution of cutting fluid of a type that is composed of water-soluble components such as surfactants, or water-soluble components such as surfactants and cutting oil such as mineral oil or chemically synthetic oil, and becomes translucent when diluted with water. A solution is a stock solution of cutting fluid of a type that is composed of components that dissolve in water, and becomes 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 synthetic 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 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. It is preferable that the amount (volume) of the raw alkaline ionized water used is such that the ratio of the volume of the alkaline ionized water to the volume of the 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. The ultrafine bubbles can be generated by using an ultrafine bubble generator. The 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 the ultrafine bubbles, the cutting fluid may contain microbubbles with a diameter of less than 100 μm and 1 μm or more.

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

[0025] The cutting fluid may contain additives other than those described above depending on the desired functions, within the range that does not impair the functions of the cutting fluid.

[0026] (Cutting fluid manufacturing equipment or cleaning fluid manufacturing equipment) The cutting fluid manufacturing apparatus will be described below, but an apparatus having the same configuration as the cutting fluid manufacturing apparatus described below can be used as the 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 device 10 may have a function of controlling the liquid A, liquid B, and liquid C supplied to the stirring tank 4 so that the total amount of the liquids is a predetermined amount at a predetermined ratio. The cutting fluid manufacturing device 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 total amount of the liquids A, B, and C supplied to the stirring tank 4 is a predetermined amount at a predetermined ratio. In this way, the labor required for manual production and refilling of the cutting fluid can be eliminated. Furthermore, even if the cutting fluid is repeatedly produced, 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 kinetic viscosity similar to that of water (0.5 to 1.5 mm at 20°C). 2Liquid A is not particularly limited as long as it has a pH of 10.0 / s, but may be, for example, tap water, industrial water, groundwater, or alkaline ionized water. The pH of the alkaline ionized water as liquid A is not particularly limited, and is preferably, for example, 12 or higher.

[0030] Liquid B has a kinetic 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 a pH of 10.0 / s, but 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, a commercially available emulsion-type cutting fluid, or alkaline ionized water. The pH of the alkaline ionized water as liquid B is not particularly limited, but is preferably 12 or higher, and more preferably 13 or higher, for example.

[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 kinetic viscosity (for example, 1.5 to 110 mm at 20°C) than Liquid A and Liquid B. 2 Liquid C has a molecular weight of 0.01 to 0.15g / s, and provides the cutting fluid with a lubricating effect. Liquid C can be, for example, a mineral oil or a surfactant. The surfactant may be a solution diluted with a solvent such as water or a lower alcohol to increase the fluidity at room temperature.

[0033] There is no particular limitation on the combination of liquid A, liquid B, and liquid C. 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 (having a kinetic 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 where liquid C is a surfactant solution.

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

[0035] Even when the cutting fluid is obtained by mixing two fluids instead of mixing three fluids as described above, the ultra-fine bubbles described below can be introduced into the cutting fluid. For example, when alkaline ionized water is mixed with water, the ultra-fine bubble generator 6 can be used to introduce ultra-fine bubbles into the cutting fluid and also to obtain the stirring effect of stirring the water and alkaline ionized water.

[0036] The introduction of ultra-fine bubbles into the cutting fluid will be described. The introduction of ultra-fine bubbles may be performed before stirring the liquid in the stirring tank 4, in parallel with stirring, or after stirring. Ultra-fine bubbles can be added to the mixed liquid before or during stirring of Liquids A to C, or to the cutting fluid obtained by thoroughly stirring these liquids. At least a part of the mixed liquid or cutting fluid in the stirring tank 4 is supplied to the ultra-fine bubble generator 6 via the supply paths 7d and 7e. The mixed liquid or cutting fluid in the stirring tank 4 can be sent to the ultra-fine bubble generator 6 by driving the pump 9a with the valve 8f closed and the valves 8d and 8e open. The mixed liquid or cutting fluid to which ultra-fine bubbles have been added by the ultra-fine bubble generator 6 is returned to the stirring tank 4. By repeating this process, ultra-fine bubbles can be introduced throughout the mixed liquid or cutting fluid in the stirring tank 4. The operating time of the ultra-fine bubble generator 6 can be adjusted as appropriate. In addition, by returning the mixed liquid that has passed through the ultra-fine bubble generator 6 to the stirring tank 4 in this manner, the effect of stirring the mixed liquid can also be obtained.

[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, 7e and then circulated back into the stirring tank 4, thereby obtaining 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 of approximately 0.10 μm were confirmed. In addition, when the ultra-fine bubble generator was not driven and the other conditions were the same, the liquid was sent outside the mixing tank 4 via supply paths 7d and 7e and then circulated back into the mixing tank 4, 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 through the supply path 7g by opening the valves 8g and 8h and driving the pump 9b. The cutting fluid may be automatically supplied to the coolant tanks depending on the amount of cutting fluid remaining in the coolant tank. The storage tank 5 is connected to a plurality of machine tools 20a-20c, and it is possible to appropriately select any one of these machine tools 20 to supply cutting fluid to.

[0041] A cutting fluid can be produced by supplying water to an agitation tank, supplying alkaline ionized water to the agitation tank, supplying mineral oil, chemical synthetic oil and / or surfactant to the agitation tank, and agitating the supplied water, alkaline ionized water, mineral oil, chemical synthetic oil and / or surfactant in the agitation tank. The time required for producing the cutting fluid can be shortened by generating ultrafine bubbles in the mixed liquid containing the supplied water, alkaline ionized water, mineral oil and / or surfactant, or the cutting fluid obtained by agitation with the agitation means. In addition, the cooling effect of the tool during cutting can be improved by generating ultrafine bubbles in the mixed liquid containing the supplied water, alkaline ionized water, mineral oil and / or surfactant, or the cutting fluid obtained by agitation with the agitation means. Alkaline ionized water has a high cooling effect, and when cutting is continued for about two hours with a machine tool using a cutting fluid containing alkaline ionized water, the temperature of the tool can be kept about 50 degrees lower than when a cutting fluid containing water instead of alkaline ionized water is used. Furthermore, by carrying out only two of the supply of water, the supply of alkaline ionized water, and the supply of mineral oil and / or surfactant, it is possible to produce different cutting fluids. It is also possible to supply the cutting fluid obtained by stirring to a storage tank, and to supply the cutting fluid stored in the storage tank to a machine tool.

[0042] The cooling effect of alkaline ionized water was confirmed by the following experiment. A stainless steel plate (150mm x 100mm x 10mm) with a thermocouple attached to the center was heated in a constant temperature bath at 350°C, then removed and 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 kinetic 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 the stirring tank, and the supplied Liquid A, Liquid B, and / or Liquid C can be stirred in the stirring tank to obtain a cleaning fluid or cutting fluid containing alkaline ionized water obtained by mixing three different types of liquids.

[0044] By making the cleaning fluid or cutting fluid contain 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. Therefore, putrid odors are less likely to occur and putrefaction is suppressed, so the amount of waste fluid generated by changing the cleaning fluid or cutting fluid can be reduced. The use of alkaline ionized water leads to an extension of the life of the cutting fluid by preventing putrefaction, and also leads to a reduction in the number of steps required for tool replacement and flushing. The use of alkaline ionized water improves the drainage of cutting fluid adhering to the workpiece and cutting chips, resulting in a reduction in the amount of waste fluid. By adding ultra-fine bubbles to the cutting fluid, the production time of the cutting fluid can be shortened and the cooling effect of the tool during cutting processing can be improved.
