The present disclosure relates generally to high viscosity lubricants that may be used in machining processes. Machining lubricants, also known as cutting fluids, are commonly introduced in the machining process to enhance the performance of machining parts. In general, lubricants reduce the heat and friction in the contact region between the machine tool and the work piece. They also assist in work piece chip removal, reduce the likelihood of tip welding, reduce or eliminate oxidation, increase the lifetime of the working tool, and allow for a more accurately manufactured work piece.
Many machining lubricants are liquid based which allows them to be easily sprayed onto the contact region to cool and lubricate the cutting tool. To be delivered in this manner, the lubricant usually has a low viscosity. The low viscosity of the lubricant also means that the lubricant can quickly transition through the contact region and drain away thus requiring additional lubricant to be applied. Additionally, applying the lubricant as a spray means a significant quantity of lubricant is never applied to the contact area and is thus wasted. Also, some lubricants include chemicals that are harmful. Prolonged exposure to cutting fluids may result in skin disorders, respiratory problems, and even cancer. Spraying the lubricant makes this unwanted exposure more likely as much of the lubricant is lost into the air and applied to surrounding surfaces.
Disclosed is a high viscosity lubricant for use in machine work. In one example, the lubricant includes avocado oil which is a naturally occurring plant product that can also provide lubricity at higher temperatures. In another aspect the lubricant may include over 20% avocado oil. In another aspect, the lubricant has a viscosity that allows it to be dispensed as a paste, gel, or semi-solid. In another aspect, the lubricant includes wax to increase viscosity, the wax may be of any suitable type such as, for example, paraffin based wax or, more preferably, soy wax.
Soy wax as used herein may include between 50% and 100% of high melting point soy wax and between 0% and 50% of low melting point soy wax, provided that the total of them is 100%. In another aspect, part of the soy wax, preferably not more than 50%, may be replaced by other waxes of natural origin, such as, for example, beeswax or carnauba wax, or other waxes derived from the hydrogenation of various vegetable oils such as palm oil, corn oil, sunflower oil, peanut oil, olive oil or cottonseed oil, among others.
In another aspect, the high-viscosity lubricant may be applied as a paste, gel, or semi-solid to the inside of a hole, groove, or other negative space defined by a work part. For example, the lubricant may be applied to a hole while machining threads in metal. In another aspect, the lubricant may be free of water.
In another aspect, the lubricant may be dispensed from a rigid tubular applicator as a semi-solid or paste. The applicator may optionally be a twist-up type where the lubricant projects outwardly from the tube when a portion of the tube is rotated.
In another aspect, the lubricant composition may include over 75% emollient carriers, and may optionally include boric acid to reduce flammability. In another aspect, the lubricant may be produced by combining emollient carriers and avocado oil at between 100 and 180 degrees Fahrenheit. In one example, the emollient carriers and avocado oil are combined at about 140 degrees Fahrenheit. In another aspect, the lubricant may optionally be used with any of the following material types aluminum, brass, carbide, cast iron, copper, fiberglass, glass, iron, nickel, plastic, rubber, stone, stainless steel, steel, and/or titanium, or any combination thereof.
In another aspect, disclosed is a lubrication device that includes a container having a closed end and an open end, the open end selectively covered by a cap. The lubrication device may also include an actuator assembly having a rotating member outside the container, and a lubricant inside the container, the lubricant optionally having a mixture of avocado oil and soy wax that has a high viscosity at room temperature of at least 1×10{circumflex over ( )}4 centipoise.
In another aspect, the lubricant may be coupled to the actuator assembly and retained within the container by virtue of the actuator assembly and high viscosity of the lubricant. In another aspect, the actuator assembly may be arranged and configured to selectively extend or retract the lubricant from the container.
In another aspect, the wax includes, or is predominantly, a soy wax. In another aspect, the lubricant may include over 20% avocado oil by weight. In another aspect, the lubricant includes over 75% emollient carriers by weight. In another aspect, the lubricant further includes boric acid to reduce flammability. In another aspect, the emollient carriers optionally include soy wax. In another aspect, the soy wax optionally has a melting point that is above 50 degrees centigrade. In another aspect, the lubricant includes at least 40% avocado oil by weight to increase temperature resistance. In one example, the lubricant includes at least 20% avocado oil by weight, at least 75% emollient carriers, and the emollient carriers optionally include soy wax.
In another example the actuator assembly includes a plunger that engages the lubricant. The rotating member optionally extends into the container and engages the plunger. In another aspect, the plunger is optionally configured to move inside the container toward the open end when the rotating member is rotated in a first direction, and toward the closed end when rotated in a second direction opposite the first direction. In another aspect, the cap is coupled to the open end of the container. In another aspect, the lubricant has a high viscosity of at least 1×10{circumflex over ( )}8 centipoise at room temperature.
In another aspect, disclosed is a method of using the lubrication device which includes opening the cap to expose the open end of the container, optionally engaging the rotating member to extend an exposed portion of the lubricant from the open end of the container, and applying the exposed portion of the lubricant to a work piece. In another aspect, the lubricant is optionally oriented vertically with the exposed portion directed downward into the hole when the lubricant is applied to the work piece. In another aspect, the work piece includes aluminum, brass, carbide, cast iron, copper, fiberglass, glass, iron, nickel, plastic, rubber, stone, stainless steel, steel, and/or titanium, or any combination thereof.
In another aspect, the ingredients used in the disclosed high-viscosity lubricant are eco-friendly and sustainable. Preferably, the lubricant is free of known carcinogens and includes carbon neutral and sustainable materials. In another aspect, the lubricant container includes bio-degradable compounds.
The system and techniques as described and illustrated herein concern a number of unique and inventive aspects. Some, but by no means all, of these unique aspects are summarized below.
Any suitable couple mechanism for the cap may be used. In another example, the cap 110 is coupled to the housing 105 with a threaded connection. In another example, the cap is coupled to the housing and selectively movable away from the opening 140 while still coupled to the housing.
In another aspect, the actuator 120 may be rotated clockwise and/or counter clockwise direction to move a threaded portion 125 that extends into the container and the lubricant. The rotational movement of the threaded portion 125 causes a riser 130 to move within the container either toward or away from the open end 140. In one example, the clockwise rotation of the actuator 120 may result in clockwise rotation of the threaded portion 125. This rotational movement may then cause movement of the riser 130 which in turn may result in movement of the lubricant 135 either toward or away from the opening 140. The threaded portion 125 may also retain the lubricant 135 within housing 105 regardless of whether the housing 105 is rotated in any angle or direction relative to gravity. For example, the housing may be held vertically with the opening 140 directed downward with respect to gravity, or in any position in between without the lubricant 135 coming free and separating from the housing.
As for the composition, the lubricant 135 may include a mixture of soy wax and avocado oil in a semi-solid state. In one example, the lubricant includes at least 20% avocado oil by weight and at least 75% by weight emollient carriers such as soy wax. The mixture of avocado oil and emollient carriers creates a high viscosity lubricant of at least 1×10{circumflex over ( )}4 centipoise. In another example, the mixture includes 40% avocado oil by weight, and about 25% soy wax by weight. This configuration may provide additional temperature resistance. In another aspect, the lubricant components are mixed together between 100-180 degrees Fahrenheit. Mixing the ingredients at these temperatures may optionally provide for efficient bonding of the component chemicals.
In another aspect, the lubricant may be used to lubricate a machine tool during a machining process. An example of this in operation is illustrated in
In one example, the tool 305 is a CNC machine. In alternate embodiments the tool 305 may be a power tool, a hand tool, a grinding tool, a cutting tool, a milling tool, a lathe, and/or any other tool that may be used to shape or work a material. The work piece 310 may be any suitable material of interest that is being modified by the tool 305. In one example, the work piece 310 is aluminum. In alternate embodiments the work piece 310 may be brass, carbide, cast iron, copper, fiberglass, glass, iron, nickel, plastic, rubber, stone, stainless steel, steel, titanium, and/or any other material in need of modification.
The tool 305 may contact the work piece 310 at the contact region 315 where the tool 305 interacts with the work piece 310. The contact region 315 may be the area of greatest friction and thus the region where heat and friction are most prevalent and the need for lubricant 135 is the greatest.
In one example, the applicator 100 may be used to apply lubricant 135 to the contact region 315 parallel with the work piece 310. In this example, the lubricant is applied to the tool or work piece, or both, thus optionally providing a lubricating film on the tool 305 and/or the work piece. The high viscosity of the lubricant 135 thus allows the lubricant to maintain position on the tool 305 without immediately leaking away.
In another example, the lubricant 135 is applied continuously to the contact region 315 at an angle of roughly 45 degrees relative to the tool, such as in the case of applying a threading tap to a hole. The 45-degree angle of incidence may allow the lubricant 135 to enter the contact region 315 and maintain the proper temperature and lubrication levels throughout the machining process. In a further example, the lubricant 135 is applied to the contact region 315 perpendicular with the work piece 310. This method allows the lubricant 135 to fill the contact region 315 with lubricant 135. It should be appreciated that the high viscosity of the lubricant 135 allows for a variety of application methods and angles. The lubricant 135 may be applied at any suitable angle relative to the tool 305 or the work piece 310.
The HVL undergoes a phase change at 430 at approximately 120 F. The phase change 430 represents a change in state of the lubricant 135 from a solid to a liquid. In the solid phase at 435, the lubricant is in the semi-solid state with a high viscosity. As the lubricant warms, it becomes less viscous until it reaches the phase change 430 where the lubricant 135 transitions to a more liquid state at 440.
Comparing the curves of the HVL at 415 with the MCO at 420, and the APO at 425 illustrates how the HVL advantageously performs under heating. Notably, for example, the MCO at 420 and the APO at 425 show an exponential increase in temperature with time, while the HVL at 415 shows a more linear, or approximately linear, rate of increase thus maintaining the structural integrity of the high-viscosity lubricant longer and under higher temperatures. This advantageously provides for better control of the application of the lubricant as the work piece and cutting tool become warmer during a machining process.
Combining the information from graph 400 and graph 500 gives insight into the bounds of the semi-solid state of the lubricant 135. For example, the lubricant remains in the semi-solid state from −24 F to 120 F. This wide temperature span allows the lubricant to be at a high viscosity for most machining and/or tapping applications. As has been discussed previously, the semi-solid, high viscosity of the lubricant 135 allows the lubricant 135 to be applied to the working region from a variety of angles and with a variety of lubrication methods.

As used herein, the following definitions apply to the following terms or to common variations thereof (e.g., singular/plural forms, past/present tenses, etc.):
“Actuator” generally refers to a device that causes a machine or other device to move. Actuators may be mechanical, electrical, hydraulic, and/or pneumatic. An example of a mechanical actuator is a jack screw. A jack screw consists of a heavy-duty vertical screw with a load table mounted on its top, which screws into a threaded hole in a stationary support frame with a wide base resting on the ground. A rotating collar on the head of the screw has holes into which the handle, a metal bar, fits. When the handle is turned clockwise, the screw moves further out of the base, lifting the load resting on the load table. In order to support large load forces, the screw usually has either square threads or buttress threads.
“Centipoise” generally refers to a unit of measure for dynamic viscosity. One centipoise is equal to one millipascal second. For example, water is 1 centipoise whereas peanut butter is about 250,000 or about 2.5×10{circumflex over ( )}5 centipoise.
“Dispenser” generally refers to a container, package, device, or machine for holding and dispensing a substance or substances in quantities which may, or may not be, of a fixed or predetermined size. Examples include twist-up type dispensers, collapsible tubes (e.g. for toothpast), metered dispensers, and the like.
“Lubrication” generally refers to the process or technique of using a lubricant to reduce friction and/or wear and tear between two surfaces in contact. Lubricants include solids, semi-solids, liquids, and/or gasses. Examples include grease, water, oil, wax, and/or any other material with a low friction value. The goals of lubrication are to reduce friction, reduce wear, protect equipment from corrosion, dissipate heat, provide a seal, and/or reduce contamination.
Types of lubrication include full-film lubrication, boundary lubrication, and mixed lubrication. Full-film lubrication may be broken into two types hydrodynamic and elastohydrodynamic. Hydrodynamic lubrication occurs when two surfaces in sliding motion relative to each other are fully separated by a film of fluid. Elastohydrodynamic lubrication occurs when the surfaces are in rolling motion relative to each other. The film layer is much thinner than in hydrodynamic lubrication, and the pressure on the film is greater. Boundary lubrication is found in conditions with frequent starts and stops. In this lubrication type, only the anti-wear additives and/or extreme-pressure additives are protecting the material. This is not ideal as friction is high. Mixed lubrication is a cross between boundary and hydrodynamic lubrication. In this type the bulk of the surfaces are separated by a lubricating layer, but the asperities still come into contact with each other.
“Lubrication Device” generally refers to a device used apply lubricant. The device may be configured to work with solid, semi-solid, liquid, and/or gaseous lubricants.
“Melting Point” generally refers to the temperature at which a substance changes state from a solid to a liquid. The melting point is dependent on the material in question. For example, the melting point of water is 0 degrees Celsius. Whereas the melting point of paraffin wax is 37 degrees Celsius.
“Snap-Fit Connector” or “Snap-Fit Connection” generally refers to a type of attachment device including at least two parts, with at least one of which being flexible, that are interlocked with one another by pushing the parts together. The term “Snap-Fit Connector” may refer to just one of the parts, such as either the protruding or mating part, or both of the parts when joined together. Typically, but not always, the snap-fit connector includes a protrusion of one part, such as a hook, stud and/or bead, that is deflected briefly during the joining operation and catches in a depression and/or undercut in the mating part. After the parts are joined, the flexible snap-fit parts return to a stress-free condition. The resulting joint may be separable or inseparable depending on the shape of the undercut. The force required to separate the components can vary depending on the design.
By way of non-limiting examples, the flexible parts are made of a flexible material such as plastic, metal, and/or carbon fiber composite materials. The snap-fit connectors can include cantilever, torsional and/or annular type snap-fit connectors. In the annular snap-fit type connector, the connector utilizes a hoop-strain type part to hold the other part in place. In one form, the hoop-strain part is made of an elastic material and has an expandable circumference. In one example, the elastic hoop-strain part is pushed onto a more rigid part so as to secure the two together. Cantilever snap-fit type connectors can form permanent type connections or can be temporary such that the parts can be connected and disconnected multiple times. A multiple use type snap-fit connector typically, but not always, has a lever or pin that is pushed in order to release the snap-fit connection. For a torsional snap fit connector, protruding edges of one part are pushed away from the target insertion area, and the other part then slides in between the protruding edges until a desired distance is reached. Once the desired distance is reached, the edges are then released such that the part is held in place.
“Tool” generally refers to a device or implement used for a particular function. Some examples are power tool, hand tools, outdoor tools, indoor tools, milling tools, cutting tools, grinding tools, boring tools, and/or autonomous tools.
“Viscosity” generally refers to a measure of a fluids resistance to deformation at a given rate. A fluid that has a low viscosity has little resistance to shear stress. For example, water. A fluid with a high viscosity has a larger resistance to shear stress. For example, syrup. A fluid with no resistance to shear stress is known as an ideal or inviscid fluid. This is only observed at very low temperatures in superfluid's such as liquid helium. Dynamic viscosity is measured in Pascal-seconds in the SI system and is measured in poise or centipoise in the centimeter-gram-second measurement system.
“Wax” generally refers to a lipophilic organic compound that presents as a malleable solid near ambient temperatures and may include alkanes and lipids. Waxes commonly have melting points above about 40 degrees Centigrade (about 104 degrees Fahrenheit) at which point they are commonly a low viscosity liquids. Waxes are commonly insoluble in water but soluble in organic, nonpolar solvents. Examples of include:
Animal Waxes
Waxes produced by animals, or created from animal byproducts. Beeswax is a well-known example of animal wax used by bees in constructing honeycombs. A major component of the beeswax is myricyl palmitate which is an ester of triacontanol and palmitic acid. Its melting point is 62-65 degrees Centigrade.
Another example of animal wax is spermaceti which occurs in large amounts in the head oil of the sperm whale. Raw spermaceti is liquid within the head of the sperm whale and is composed mostly of wax esters (chiefly cetyl palmitate) and a smaller proportion of triglycerides. Most of the carbon chains in the wax esters are relatively long (C10-C22). In another related example, the blubber oil of the whale is about 66% wax. When it cools to 30 degrees Centigrade or below, the waxes begin to solidify. Spermaceti is insoluble in water, very slightly soluble in cold ethanol, but easily dissolved in ether, chloroform, carbon disulfide, and boiling ethanol. Lanolin is a wax obtained from wool, consisting of esters of sterols.
Plants secrete waxes into and on the surface of their cuticles as a way to control evaporation, wettability and hydration. The epicuticular waxes of plants are mixtures of substituted long-chain aliphatic hydrocarbons, containing alkanes, alkyl esters, fatty acids, primary and secondary alcohols, diols, ketones, aldehydes. One common plant wax is carnauba wax, a hard wax obtained from the Brazilian palm Copernicia prunifera. Containing the ester myricyl cerotate, it has many applications, such as confectionery and other food coatings, car and furniture polish, floss coating, and surfboard wax. Other more specialized vegetable waxes include jojoba oil, candelilla wax and ouricury wax.
Plant and animal based waxes or oils can undergo selective chemical modifications to produce waxes with more desirable properties than are available in the unmodified starting material. This approach has relied on green chemistry approaches including olefin metathesis and enzymatic reactions and can be used to produce waxes from inexpensive starting materials like vegetable oils.
Although many natural waxes contain esters, paraffin waxes are hydrocarbons, mixtures of alkanes usually in a homologous series of chain lengths. These materials represent a significant fraction of petroleum. They are often refined by vacuum distillation. Paraffin waxes are mixtures of saturated n- and iso-alkanes, naphthenes, and alkyl- and naphthene-substituted aromatic compounds. A typical alkane paraffin wax chemical composition comprises hydrocarbons with the general formula CnH2n+2, such as hentriacontane, C31H64. The degree of branching has an important influence on the properties. Microcrystalline wax is a lesser produced petroleum based wax that contains higher percentage of isoparaffinic (branched) hydrocarbons and naphthenic hydrocarbons. Paraffin waxes are common with millions of tons produced annually. They are used in foods (such as chewing gum and cheese wrapping), in candles and cosmetics, as non-stick and waterproofing coatings and in polishes.
Montan wax is a fossilized wax extracted from coal and lignite. It is very hard, reflecting the high concentration of saturated fatty acids and alcohols. Although dark brown and odorous, they can be purified and bleached to give commercially useful products.
Polyethylene waxes are manufactured by methods that include direct polymerization of ethylene (may include co-monomers also), thermal degradation of high molecular weight polyethylene resin, and recovery of low molecular weight fractions from high molecular weight resin production. Each production technique generates products with slightly different properties. Key properties of low molecular weight polyethylene waxes are viscosity, density and melt point.
Polyethylene waxes produced by means of degradation or recovery from polyethylene resin streams contain very low molecular weight materials that must be removed to prevent volatilization and potential fire hazards during use. Polyethylene waxes manufactured by this method are usually stripped of low molecular weight fractions to yield a flash point greater than 500 degrees Fahrenheit (greater than 260 degrees Centigrade). Many polyethylene resin plants produce a low molecular weight stream often referred to as Low Polymer Wax (LPW). LPW is unrefined and contains volatile oligomers, corrosive catalyst and may contain other foreign material and water. Refining of LPW to produce a polyethylene wax involves removal of oligomers and hazardous catalyst. Proper refining of LPW to produce polyethylene wax may be ueful when being used in applications requiring Food and Drug Administration (FDA) or other regulatory certification.
Soy wax generally refers to wax that is made by the full hydrogenation of soybean oil. This full hydrogenation gives a triglyceride containing a high proportion of stearic acid. It is typically softer than paraffin wax and with a lower melting temperature, in most combinations. However, additives can raise this melting point to temperatures typical for paraffin-based candles.
The triglycerides are esters of fatty acids and glycerol, in which the three hydroxyl groups of glycerol are esterified. The main factors that determine whether a triglyceride is solid or liquid at room temperature are the degree of saturation or unsaturation of the fatty acids that constitute it, as well as their chain length. In general, the higher are the saturation degree and the length of the triglyceride's fatty acids chain, the higher is its melting point.
Soy oil mainly contains a mixture of triglycerides, mainly mono- or polyunsaturated, the majority being derived from linoleic, oleic, and alpha-linolenic acid. One can distinguish different types of soy wax according to its degree of hydrogenation, which in turn determines its melting point, so that, the greater the hydrogenation the higher the melting point is.
Soy wax can be classified into high melting point soy wax and low melting point soy wax. High melting point soy wax generally has a melting point is above 50° C., while low melting point soy wax has a melting point that is 50° C. or lower. The melting point ranges from 49 to 82 degrees Celsius (120 to 180 degrees Fahrenheit), depending on the presence of other chemicals combined with it. The density of soy wax is about 90% that of water or 0.9 g/ml. Soy wax is available in flake and pellet form and has an off-white, opaque appearance.
