"The woman is created for a man, not a man for a woman" - such a postulate ...
It can be definitely said that any home keeps their riddles. Their number in each house is yours. To cope with them, as a rule, you need to use the advice and knowledge of other people who are familiar with similar problems. One of those complex tasks It is considered to than drill a stainless steel. Not possessing certain knowledge and skills, you will probably try to make the hole you need in the layer of stainless steel, but unsuccessfully.
Instructions for the implementation of this event:
1. First of all, in order to do a hole in the stainless steel layer, you need to use a special lubricant. Most often to get this lubricant, it is necessary to mix a certain type of sulfur mixed with machine oil. The sulfur needed for this mixing is sold in special stores. When buying it, pay attention to the name of this sulfur. Its name may be as follows:
- Erotic sulfur.
- Colloid sulfur.
- Sulfurian.
If you bought sulfur, which is called "colloidal sulfur" or "sulfur", it can be mixed with oil in the form in which it is in the package. But in the event that you have a "sulfur", you must first develop it, then add oil and mix.
2. To create a lubricant with much more efficient properties compared with lubricant of sulfur and machine oil, you need to mix sulfur with fatty acids. Where to take these fatty acids? For this, the lowest is the lowest economic soap grind, and then add hot water. In the prepared soap solution, a significant amount of hydrochloric acid should be pouring, for this take technical hydrochloric acid. After the reaction of the interaction of these substances, fatty acids will be on the surface of the tank. Then add a lot to this vessel cold water. This will lead to the fact that fatty acids thicken, and they can be removed from the surface. Spend 5 precipitation procedures of fatty acids. First add hot water, then cold, collect them from the surface, and so on.
3. Having gathered a sufficient amount of fatty acids, mix them with gray. Proportions must be 6: 1. Thus, the lubricant for holding a hole in stainless steel is prepared, it remains to use it. Do not forget that, carrying out the process of drilling, the drill should not overheat. Periodically make a break to work so that the drill can cool. Not following this instruction, the lubricant may instead of helping to have difficulty in performing this event.
Compliance with uncomplicated rules
In order not to encounter difficult situations, such as, strong overheating of drilling site, extreme heating of the drill and others, must be observed simple rulesIt will help to perform absolutely smooth holes without concomitant time and money. It should also be borne in mind that due to a viscous structure of stainless steel, the reservoir of the stainless steel should be drilled on small revolutions to prevent overheating of the drill. Drills you need to use only very sharp. In addition, in order to prevent significant overheating of the drilling site, which will lead to great difficulties in carrying out drilling, every 10 seconds it is necessary to minimize the temperature of the drill.
Follow the chips during the period of carrying out drilling, if it turns out everything is smaller and darker, this means that the drill fastened, and the place of the hole in the stainless steel overheat. Therefore, you must divert the drill or change to another to successfully finish the work started. As a rule, it is necessary to start drilling with a drill having a small diameter, the size of which, respectively, four or five. Then gradually move on to the drill, which has a suitable size for obtaining the desired opening. Performing a drilling process in a similar way, you can make a smoother hole, and at the same time strongly reduce the time spent on it.

Our brother, a peasant, unwitting have to be able to do everything you need in the house. I'm not saying that a man should be able not only to eat, but also cook, even if a woman is preparing canceled. Sometimes you need (and you can) make a woman a surprise: she came, and everything is ready, just sit down. At worst - not all, but something is very tasty so that the woman missed his second (third, fourth ...) work, shift, watch, or how they talk about it yet. Despite the fact that they love to say that they love to cook (some ...), but still it (cooking) thing is not quite simple in the sense of organization and time. If the man is only eating, it's a spectacle and this fact someday and will fall out in a conversation, and then do not consider reproaches. It will take some time, and again we will be inclined on all cases. Who will like it? Therefore ... you need to take part in the "process". Although I often do not even want to take ... But you need to understand it ... Not yet only nails saw. Not everyone.
You will be "well done", if you make something necessary, as they say, "socially useful" - will bring garbage, (especially on their initiative), clean the onions, potatoes (list is large). Before that, you can even bring all this from the store, including some chicken (the list is huge). Just need some time to spend together time for cooking, cleaning (here again list ...) And then in the relationship everything will be OK (most often, I hope)
They say women can all, but it is not. If a woman can do everything, it is probably worth considering it in more detail, and it is better to ask her, and what makes her man. Or she spoiled him that he did nothing. Well still, if he earns a lot. But then ... Yes, we will not be about sad ...
But there are cases that a woman cannot do. Not women, but a woman. Women can all, especially when they are all together. Then they can give one to one man. All together ... But it happens that the woman is faced with the fact that it hits the current, as it happens to me, and not the first, by the way, once. That's strange, it beats her, but I do not. Paradox ... Skura elephant anything or drum ... in short, it does not break me. But her ...
But once thunder rolled, it is necessary ... not baptized, but faster eliminating possible reasons electric power. Turning on the voltmeter, I saw 188 volts, and after a couple of minutes only 5 ... Biot between gas stove and washing in the kitchen. Sink from a stainless steel ... It is possible that some crank, on the letter "Mu", they are still called marriages, planted its problems on the part of electricity, since it is too lazy to make a ground, and it is worthy of decent money. And here she took some wires to the pipe of the water pipe, and the case with the end. Maybe not caught. And who will catch it, who needs it? And on others, because we have us ...
I went to Google, as to how grounding should be done correctly, I was interested in what resistance should be on the contour of this grounding. The fact is that I have been made by my predecessor of the earth contour. Of course, some time passed, and on the time the magnitude of this resistance, according to the rules equal to 0.05 Ohm, less, alas, does not become.
The laboratory courtesy suggests only 2000 rubles to measure this resistance. And the fact that this resistance I have not 0.05 Ohm, I am so almost safe.
The decision was born immediately and for a long time: it is necessary to connect with a thick wire "in 6 square" those hulls, between which the voltage was observed. Obviously, the wisdom turned on its installation for a while, but then only 5 volts remained. That's 5 volts and you can try to navigate. The most important thing is that now there is a time to do - the problems with the roof now moved to the third plan - the workers made the roof, although it is not well everywhere, but this can already be corrected, for their omissions, which not stated by me after the calculation become mine. Now I have to pay, well, you know, with whom ... Therefore, you can now hire on ... electrical safety, which we do.
Wire "About six square", of course, long bought. For a long time, everything you need to correct the consequences of the activities of that possible Mudra, which created this situation on my car wash, which wipes some ... and now it is necessary to combine electrically cleaning with gas and part-time electric furnace Production of respected by me by Bosh. Descriptions, as always, in place and did not turn in time. I called the store where we bought this miracle oven. The question was such: where the point is displayed to which it is possible to pick up grounding in this apparatus. The seller said that you need to join the ground to the fork, to its grounding contact.
Honestly, this contact always seems to me that there is insufficient, some ephemeral. Consciousness begins to draw large currents that can go through this, in my opinion, squeezed contact, which is carried out so strangely. Another thing is when there is a petal on the housing, or some place where you can attach this ground.
But since we are pushed at such a step, you have to try, join this wire on the fork, which is just a grounding contact and the housing of our furnace is connected to it.
In order to join the sink, you need to create constant contact with the sink. Attach the clamp with a grounding wire to the sink will be ugly, I'll also blame me now, I know it perfectly. So, you need to drill a stainless steel to create a connection.
But after all the trouble: the stainless steel will not be drilled, especially from the direction from the side, where this connection will not be visible. I climb into "Google" with the question: how to drill a stainless steel? It is necessary, it turns out, to use ... and sulfur (?!) For drilling, and to make it all, it is necessary to mix the soap with hydrochloric acid and ... Read it, as it all complicates, although it is probably necessary to do it, but Where to run something for acid looking at the evening?
Fortunately, someone intelligent advised to drill, first, on very small revolutions (this was all advised, the advisers from former country Soviets, and what only they did not advise, in particular, to use ... Soviet drills from Steel P9 and P18). Well, where they are right now, in the evening, you will find? We have everything imported, even ... drills.
It is necessary to use cooling drill from oil and other liquids. And in addition to the screwdriver and the pair of drills are nothing. Yes, and the surface that must be drilled, is vertically and you can not raise this very sink to arrange yourself at least some convenience so that you can at least press the screwdriver with the drill ... in a word, the problem.
And secondly, smart man advised such exotic for drilling, like ... Salo. I climbed into the refrigerator, I did not find Sala, although I know for sure that somewhere we have it. And give, I think I will try ... Smoked-boiled breast, which I feel almost every day. Before that I tried drills, and German high-quality, and cobalt, yellowish color. All in vain. And the revolutions changed from a minimum to the maximum. Nothing helped, there was only a tiny moon in a stainless steel, and the drill refused to do their job. But I took a piece of breast, immersed the drill to the place where Salo was, turned on the turnup, scored a fat on the drill and began to drill its recalcitable stainless steel to the "cobalt" drill. I had to "score bass" a couple of times on the drill and, about a miracle! I got a hole in the stainless steel. And the thickness of this stainless steel is quite a little bit, but it was not thrilled after all ...
After a couple of minutes, the hole of up to three and a half millimeters was expanded the same manner, then a bolt is inserted with washers, and between them the wire, one end, the cable tip for a bolt with a diameter of 4 millimeters was in advance. On the bolt, on the other hand, lamb was planted so that it was possible to conveniently enhance contact with a stainless steel washing, which turned out to be practically not very disfigured by the protruding ball head. Everything else hid in space under the sink.
Why do I describe all this in this way? After all, I still need to make the wire on the other hand, connecting it to the sink of electric furnace. I just wanted to emphasize that such exotic as fatIn my case, played a key role. If the fat did not help, the economic soap would go, the machine oil (list is small, alas), but Salo and here it helped at all I salo very much, especially with meat veins, delivered from the freezer and finely chopped on the typewriter
So, if anyone have to drill a stainless steel, then this is necessary for success: the sharp new quality drill is hardly up to the dental bagu, small speed and ... fat, as ... coolant. (I even looked at the site, as drilling, or rather, burn in the stainless steel of the British hole. But these are ...)
Well, and then, after all the deed, all that was needed, maybe, as a snack, a woman will not beat, I hope ... the winners are usually not judged. Although, anything happens ...

Stainless steel is widely used in the household and industrial sector to create various items due to a significant amount positive qualities. It is a alloy different materialswhich gave stainless steel corrosion resistance and aggressive medium. Based on their percentage, the alloy can create different types material.
At home, it is often used objects from the so-called food stainless steel, cranes and mixers, sinks and washing in the kitchen, dining room tableware and other things. Therefore, often for any purpose you need to drill a stainless steel. However, the process should be prepared. That is, to study the recommendations more experienced mastersIf the procedure is done for the first time with your own hands, as well as pick up suitable drills and lubricants.
In addition to experience, it will take a thinness of sensitivity and attentiveness. This is far from the only thing that the master is required. Most of all when drilling helps lubricating fluid, without which the master risks damage drills and material. The lubrication consists of machine oil and sulfur, so it is easy to recognize on viscous form and increased fatty. Besides right choice Material, you need to know some of the features of how to drill a hole in the stainless steel.
Nuances when drilling
What needs to be done is to determine the tool. What exactly use depends on how the diameter needs holes. If up to 12 mm, then at home, cost a hand drill.
Nothing else will help to reveal the holes in the stainless steel, as a preliminary markup. It is especially effective when single holes are made or treated and handled and sheet metal. Under the drill on the workpiece are applied axial risks, and then make a slight recess in the product. Later they deepen them to the desired size.
The template is what else will help save time when drilling, because the contours of the holes are noted on it. Masters have to go for a trick when the work is performed with the edge of the surface. Typically, it is necessary for semi-sides, which are made as follows: to the processed product attach a plate of the same material that is clamping in the vice. After that, it is possible to take a standard deepening, and at the end of the work simply remove the attached plate.
Useful techniques when drilling
Each master who has gripped his hand in this matter, there is a couple of cunning techniques, significantly simplifying the drilling process. Many videos and photos on the site will clearly demonstrate what and how to do.
First of all, attention should be paid to which plane is a working surface. When you need to drill a hole in a horizontally located object, cooling fluid poured into a small plugThrough which the drilling is carried out.
If the design is installed vertically, then the ball of paraffin is attached to the place of the future hole. Thanks to such tricks, it is possible to quickly perform work even in the most inconvenient places.
Other an important nuancewhich should be remembered when you plan to drill stainless steel steel, installing a drill to minimal rev.. To get standard holes sufficiently speed up to 150 revolutions. With too high revs, the lubricant simply will not have time to cool the drill.
What to do with that equipment where there is no speed switch? Press the "Start" button and release 1-2 seconds. If you work with such short presses, the drill motor will not develop a greater speed.
If there is a lot and often drill a stainless steel, you should buy a special stand for a drill. IN financial Plan Costs will be small, and the process will be much simplified.
It is possible to determine that the drill was blocked or overheated, it is possible to darke chips. Therefore, the wizards are first used to use a small diameter drill, for example, four. Then the hole is brought to desired size, getting smooth and neat edges. This is especially important when stainless pipes are drilled. In this case an ideal result can be obtained only with a special step conical drill. When it is required to make a hole of a large diameter, from about 15 millimeters, apply a crown, simply speaking, crown.
Use of lubricants
So that the procedure fails fails, you need to use cooling materials. The thing is that stainless steel is characterized by increased viscosity. In the process of operation, the load is at the same time on the drill and material, as a result of which the overheating or one or the other may occur. Therefore, it is so important to foresee than to cool the tool.
When you have to drill a lot, it is reasonable to attach an automatic lubricant supply to the machine. If the drilling is a single and rare case, then process the drills immediately before drilling. As a lubricant, a mixture of machine oil and sulfur is used. At the same time, the sulfur can be taken both colloid, and for the fusion, well known as "sulfur".
If it was purchased in the form of a powder, the substance is simply mixed with machine oil. When sulfur is a piece of sulfur, it will still be overcome. Effective coolant is a mixture of sulfur with fatty acids that can be obtained from the usual economic Soap.
For this, the following actions are performed:
- a piece of soap is rubbed, and the resulting mass is poured with hot water;
- technical hydrochloric acid is carefully poured into a soap solution;
- when fatty acids will float on the surface, pour cold water;
- wait until they harde and remove the top layer.
When creating cooling material, fatty acids and sulfur is taken in proportion 6: 1. The efforts and time are justified, because such a composition will help to drill even the largest stainless steel.
Choosing a drill
Choosing a reliable drill - an important stage When preparing for drilling. You can find foreign tools manufactured according to the DIN-338 standard and having HSS-CO labeling. It becomes clear that the composition has at least 5% of cobalt, as in the old Soviet drills. Recognize the product for stainless steel can be blunt corner sharpening, which facilitates the centering at the beginning of work. Such a tool is easy to get in any specialized store at an acceptable cost.
As for the carbide tool, it is suitable for processing stainless surface and products from this material. But there may be problems with its acquisition, since such drills are not available in every construction store, plus it is much more expensive.
When choosing tools, only high-strength products should be purchased. You can search for old cobalt drillswhich are still considered the best. If there is a failure, then it is worth staying on the products of Ruko, Bosch, Gross, Hilti, which are in most shops. The price depends on the diameter, for example, the 3 mm tool can be bought from about 100 rubles. The larger the diameter, the higher the price. This craftsmen will not work to fit the angle regular drill In the presence of a diamond circle house.
Industry and high product certification requirements in international markets lead to wide application Quality stainless steel. Designers when creating projects prefer welding connections of individual nodes.
Connection bolted, the riveted from this did not suffer and is often used in modern designs. The drilling of stainless steel may be needed to create technological holes. Presented in this article the material will give general concepts and the features of this process with anti-corrosion alloys.
Preparatory work
Preparatory work consist in eliminating some negative factorsConjugated with the drilling of stainless steel. Consider what properties make difficulties in this process:
- The chemical composition of stainless steel grades helps to increase the plasticity of the metal. The chips when drilling such steels sticks to the drill, from this cutting edges are excluded from the process, and on the walls inside the unfinished hole, slope is formed. Such a superficial slope makes it difficult further processing And changes physical properties in this place.
- The heat removal from the rotation heated and cutting the drill occurs over the metal surface. Without conducting warning events, you can get a section-colored section around the drilling. In addition to the spoiled decorative surface, it reduces the corrosion resistance and requires additional technological operations to restore the specified parameters.
To avoid the shortcomings described above, it is necessary to decide before drilling to be solved as the surface will cool and what to do to eliminate sticking chips. Among effective methods Suitable water. If the volume of the muscles is more than one hole with a diameter of 10mm in a sheet with a thickness of 2 mm, then it should be thought about cooling with an oil or a special emulsion.
Attention. Cooling with water when drilling a stainless steel is made during the process itself. Cooling by lowering the hot drill in a jar standing nearby leads to hardening and metal leave and loss of basic properties. The coolant is fed to the contact point when drilling. To reduce the consumption, you can put a rubber ring on the surface, surrounding the contact point. 
Drilling modes
The correct choice of drilling mode is the key to getting a high-quality hole. The main components of the speed, feed and torque.
Cutting speed - The conditional value defining how quickly the point rotates on the surface of the instrument relative to its center. This means that for different diameters, the drills need to choose different revs to achieve the same cutting speed.
Example. For steel 08x13n with a thickness of 10-15 millimeters in the directory, the speed of cutting 20m / min is indicated. If necessary, drill a hole with a diameter of 1 mm Spindle rotation speed drilling machine Must be 6366 revolutions per minute. If the hole is drilled with a diameter of 10 mm, then turns should not exceed 637 revolutions in 60 seconds.
Drill feed In the metal means the value of moving to the depth of the opened hole for a certain number of revolutions. That is, this is the immersion rate. It is measured in millimeters for 1 turnover. It is important to withstand recommended values \u200b\u200bto obtain a qualitative result and reducing the effects of chips on cutting edges. 
Torquetransmitting drill in the process of drilling is an important factor for drill and material, determines the selection of steel for drill and composition of cooling fluids. By conventional words, it is a load on the drill, resulting from the resistance of the material by deformations created by the edges of the drill.
The choice of each of the parameters is due to the stainless steel brand, the sheet thickness or part, the choice of equipment, the selection of the cooling method, the material of the drill, surface roughness and other factors. By major brands there are many reference literature and regime cards. Proper selection And the high qualifications of the technologist, which make up the regime cards, will avoid additional processing operations and finishing, reducing the cost of production.
Drills for stainless steel.
The variety of drilling equipment today can put even experienced professionals in a dead end.
The most common are cobalt drills. Their name indicates the presence of cobalt in chemical composition Alloy. Stainless steel drill belongs to high-speed steel products. The increase in the percentage of cobalt increases the redstability, the alloy will retain its properties after heating to the temperatures of red cagine. These include instrumental steel P6M5K5, main material for manufacture cutting tool For stainless steel in domestic and foreign markets. 
In addition to the material, the design of the drill itself is important. The most expensive and qualitative of them are manufactured using technology when grooves form on grinding machines. The absence of deformation stresses makes them stronger and expands the mode parameters of drilling. Such grooves do not have microscopic sizards and simplify the output of chips, preventing the sticking of grooves. The coaching angle of drill must be 135 degrees. This leads to a reduction in the load. 
Drilling technique
The drilling of the opening of more than 6 millimeters must be produced in two stages. First, the hole is drilled with a diameter of up to 5 mm, and then it is brought to the required diameter. The absence of internal voltages before drilling will be simplified and expand the range of modest parameters. This will prolong the service life of the drill, will avoid surface overheating.
Before drilling stainless steel, find out its brand, thickness, recommended drilling control parameters. Decide with coolant. If there is no such, you can use vegetable oil (Olive or sunflower), Saletz, Emulsion of Economic Soap in Water.
