Introduction
Although I'm sure you all understand the concept of friction'm see many of you probably do not know the term "lubrication". Lubricity is defined in Merriam-Webster Dictionary as: the ability to reduce friction. You may also recall that the ability of a lubricant (oil, water, Teflon, etc.), to reduce friction between two objects. For your information, is the study of lubrication of the biggest science of tribology - the study ofSurfaces in relative motion. While this information can be very interesting and some annoying, others, it is important for everyone to understand the real, want to grind and polish the blade. So if you belong to this particular group or would like to continue reading.
Lubricant & The Pursuit Of The Perfect Edge
Since the search for perfection is the cutting edge of our program here, let the principles of the lubricity of sanding and polishing are good knives. Suppose you have a flat surfacecovered with a liquid, the particles that are harder than steel. Suppose also that we are a steel blade to move on this surface, with only the weight of the blade for the downward pressure. Since the increased lubricity of the fluid, the friction between the abrasive surface and the contact of steel, the surface decreases. This reduction of friction reduces the ability of the abrasive to remove metal. The extent to which an abrasive material will be removed bythe "shear" of the abrasives.
Since the average power is what we all want from our rough, we always want to keep the lubricating ability at least, is not it? Well, it depends. Have you ever tried sharpening a blade of water on a dry stone? How about on the dry-DMT diamond plate? If so, you have already experienced the effects of the lubricating very low - more or less metal is removed (not always where you want) and the stone or plate will soon be clogged with metal shavings worn.This makes the surface of an abrasive cutter inconsistent - and a few other points that will cut hard and, where average power is practically nonexistent. Moreover, this lack of lubrication also makes for a very rough edge - something that can be seen under a microscope, and, of course, you feel on the skin.
The role of lubricants in the creation of a better board
E 'for these reasons, we usually use a lubricant (which increases the lubrication), if we are sanding. Lubricants reduceThe friction between the abrasive and the blade - to reduce the average power, but produce a more substantial "cut" and a smoother edges. The lubricant also helps to remove the metal (and particles "used" abrasive), by the abrasive action, so that the "block" Hon-or remove the surface when the surface is too dry to be avoided. Eventually extended the life of a lubricant with an abrasive surface.
Proper lubrication is especially important if youAbrasives that sharpen considerably more difficult than the piece that you try to polish or are you - and not everyone is harder than diamond. Diamonds, natural or synthetic, are the hardest substance on earth. The difficulty is not the same force - you could take a hammer and gently compressed the engagement ring (do not try this at home), it just means that if they moved against a softer material (which is different from everything else in another diamond of the Earth) with enough pressure, theThe diamond is cut into the material and remove some of them. The depth and shape of this cut, and the amount is removed from the material, are all influenced by the shape of the diamond, the pressure applied to the workpiece against the diamond-and last but not least, is the piece of the settlement between him and the softer material.
Water is the most common and least expensive lubricant. It also has very low lubricity and viscosity (a measure of the resistance of a liquid under pressure,one of the reasons why it is not used to lubricate the moving parts of engines is in cars and trucks - often known as "thick"). It does, however, the qualities that are very desirable to have when honing a razor, knife or fine tool. And 'plentiful and cheap, easy to clean and has a job fair put on metal fatigue and spent abrasive, to ensure a consistent "cut" and extended the life of abrasive materials. It also helps to produce a less jagged edge, as you wouldotherwise have a dry surface, although not as smooth as it gets to it with a lubricant higher.
The Princess and the Pea - as something very small can be very irritating
Although the main theme of this work, I leave the subject for a little lubrication 'to overcome the abrasive particles in microns and above all, speak the sub-micron level. You have to trust me that this is important and that brief detour back to the topicin a few paragraphs. First try in a hurry, our brains around the concept of micron-sized particles in the wind. To view in microns, one can assume that the point at the end of this sentence is about 400 micrometers wide, and that a micron is about 1/300th the diameter of a human hair. Sub-micron level are apparently even smaller particles - so small, in fact, that electron microscopes are needed to see them.
Despite the small size, aresludge is a common complaint, use the diamonds to less than one micron in size - have an advantage that is too difficult to leave or "teeth". This seems somewhat counter-intuitive, if the particles are so small, but it's true. This effect leads honemeisters many (skilled in the edge perfect) and chromium (a substance that is softer than diamond) using strops inserted after the use of diamond spray. The argument goes something like this: "Diamonds are aheavy substance and it cuts deeper scratches and rougher as chromium oxide, chromium oxide honing on 'therefore necessary to' smooth 'the edge. "This is only partially correct and it is usually through the use of the wrong type of diamond in the wrong way.
Synthetic diamond single crystal (SMD)
Most of the formulations for the diamond blade for sharpening blades (including those sold by market leader current hands-American) to be sold are based on synthetic single crystalDiamonds (MDS) as an abrasive.
People at extremely low cost and long life, SMD diamond suspensions are an excellent choice for the material initially, but they have some inherent problems that make it a poor choice for the final completion of work. These problems are mainly the shape of the particles themselves, is "blocks" with very strong, but very few edges. SMD mud also suffer from problems with the form of particles, such as the existence of needle-like"Splitter" and long, flat "flat structures." Fragments of damage to the blade beneath the surface - these "stray" who moved frequently and past even the highest quality particle size distribution (PSD), test equipment to be relatively high "interest free" Lead SMD. These scratches are not visible through the microscope magnification, normal (you would need an electron microscope to see them), but can be an advantage for shaving, as they used to be perceived "hardness".
For thisReasons SMD diamond suspensions are not the first choice for producers of the need to produce the best surfaces. They are not recommended because the use of diamonds used in MDS sub-micron level mud for finishing / polishing. Although beyond the scope of this work is to investigate the morphology of diamond subject, I say this because I felt I had a complaint on the website of the current market leaders, hands-American, that are mono-crystalline diamonds moresuitable for finishing, why not leave a "tooth edge", such as polycrystalline diamond (# http://www.handamerican.com/compoundnotes.html 20Shape% of the particles). This is simply untrue. In fact, there are numerous studies to achieve exactly the opposite conclusions.
Synthetic polycrystalline diamond (SPD)
Synthetic polycrystalline diamond (SPD) share many properties of their mono-crystalline cousins (especially hardness), but their structure - made up of a subsidiaryDetonation of explosives is very different. Each contains tiny particles even smaller Social Democratic Party "microcrystalline", whose many aircraft are in different crystallographic directions every 10 to 50 nanometers (a measure much smaller than a micron) attention - regardless of the size distribution of particles parent. The micro hardness of the individual crystallites can be compared with the synthetic monocrystalline diamonds. Due to the increased number of sharp andremove more surface contact with the workpiece at the same time, SPD-based muds more metal sludge and SMD are much less likely to cause damage to the metal underground ±. But all these good qualities to come at a price - with polycrystalline diamond costs much more than mono-crystalline preparations.
Lubricant Revisited
Earlier in this article I described the problems characteristic use of abrasive products with little or no oil - inconsistent cut, cut hardand obstruction of the abrasive surface. Given what we know about the "stray" particles in the sludge of MDS learned, it's no wonder that these problems would be exacerbated by a solution with very low lubricity - especially when using particles with a tendency to "pipe?" Scratches did not deteriorate in the absence of lubrication?
Most diamond blades sprays, such as those produced by hand-American (I have a 4 oz bottle of.25 micron monocrystalline silicon slurry sprayfor $ 34.95 from chefsknivestogo.com), use the carrier (the solution in which the abrasive particles in suspension) with very low oil - depends primarily on de-ionized water to reduce friction. You can see how they sprayed them in the product (spray) - a fine mist, similar to tap water (a little 'too good, in my opinion, at a distance from 5 to strop ", leads a circle approximately 8. "diameter - there is more mud on the table near the shotcrete that strop.Sludge to be "concentrated" at one point.). Also dries very quickly to 100% heavy wool felt strop - a sign of a primary dependence on water as a lubricant. You may also think that the almost complete absence of viscosity in the perception of "draw" or friction when you pull a knife against a wool felt hard on the hand strop American product to be treated. And since it is often dry (which may or may not be the method of use are - no instructions included), is that the frictionbetter - at least until the debris of metal begins to clog the surface.
So, after spraying strop a razor blade of wool felt hard on this product, wet or dry, I find that pulling chromium oxide before use is necessary - as the blade is sprayed from a way that tends to leave a strop hard edge. If you work with a knife, you will probably want a border more difficult - especially in sub-micron level, as microscopic scratches may produce a better media - you mightwant to pay less.
How To Get The Ultimate Edge for less money
We are looking for customers around the world, to put the perfect edge razor blades, knives and tools in fines. In response to these needs, has little StropperTM products that are less expensive synthetic monocrystalline diamonds in our mud 1 and 2 microns (where a zero rate is less than significant and perhaps even desirable) is made and more expensive synthetic polycrystalline diamond (SPD) our.50and.25 microns microns sludge. Since the sub-micron level can be used for finishing and polishing sludge tend to be, we felt that the use of polycrystalline synthetic diamond, scratching with their much lower prices, it was worth the extra cost. In all of our recipes that we use in much higher water-soluble lubricant, such as is found in leading brands. To feel less friction when you use our products, but you will get a better and smoother edges. They are alsoless the product of how we have developed special ingredients to pull off the surface wet for a long period continue to add.
Another thing is that I appreciate our prices. Our formulations SPD using much more expensive diamond products of our MDS are a little 'less than the leading brand. Depending on the formula used, the cost of our products ounce for ounce up to 35% less than similar products. We announce the following products, which will be availableSales in January 2011:
× 2 micron monocrystalline synthetic diamond disks Premium Spray (2 oz size) × 1 micron monocrystalline synthetic diamond disks Premium Spray (2 oz size) ° 0.50-micron polycrystalline synthetic diamond award slurry spray (2 oz size) ° 0.25-micron polycrystalline synthetic diamond award slurry spray (2 oz size) · SlurryLubeTM - a good diamond disks and extender oil (2 oz size)
Warning participants bearing Carats
A word aboutthe wise - be careful with diamond blade manufacturers that distract you from the price for their product, trying to calculate the number of carats of diamonds in the bottle. "Stuffing" diamond dust deeper into a bottle of liquid manure, and certainly provides a justification for paying a high price is unlikely to improve product performance. The diamond particles additional wasted until the end. Our products are formulated with a focus on performance and results - not in caratsWeight. So you end up paying for effective, non-diamond powder.
Completion
I have a lot 'of science and jargon used in this document - I apologize and have tried to keep it as low as possible. But most of you reading (and thanks for coming with me so far) not tribology. They are people who want to know how I, a shave every day. Want to knife to cut cleanly without slipping. Would you like chisels and other tools, the blade is removedMaterial reliable and "skip" areas or damage to your creations. You want to have even less time and money there.
