How to cut aluminum figure skating. Circular Saw.
Than and how to cut an aluminum profile
Aluminum plasma cutting. ideal option to get high quality cutting of non.ferrous metal. At the same time, only inactive gases are used for the formation of plasma necessary for the processing of aluminum sheets and its alloys: hydrogen, argon or nitrogen.
Active gases, such as air and oxygen, are designed to form plasma for cutting black metal.
It is not recommended to use a gas mixture combining nitrogen with an argon for plasma cutting aluminum, as it is designed for cutting 50 mm highly alloyed steel.
The use of pure nitrogen gas is possible for cutting aluminum with a blank thickness up to 20 mm.
But nitrogen in combination with hydrogen will allow you to treat aluminum and its various alloys, with a thickness of 100 mm.
Price list with the cost of plasma cutting aluminum
|The thickness of the aluminum sheet, mm||Price per meter (linear)|
The final cost of plasma cutting is determined individually based on the quantity and configuration of products.
Plasma cutting of aluminum plates, aluminum and its alloys, provides a clear outline and even fishing line for a cutting trimmer. The efficiency of aluminum plasma cutting is also important, when a minimum amount of materials is consumed on a small cut width. Compared to oxygen, professional plasma cutting of the FZM has a much higher speed. It requires lower financial costs and it does not contribute to the modification of the metal. The quality of work when using plasma cutting of an aluminum slab or aluminum sheet is much higher than when cutting a laser.
Features of aluminum processing
Many questions from the townsfolk are raised by cutting soft metals. In particular, aluminum. To process such material, there is a wide variety of nozzles for sawing, which have different diameters. Also released and circles for grinding aluminum. Description of cutting circles for corner grinders must be started with their size. So, the external diameter of such products varies from 125 mm to 230 mm. The thickness of the cutting nozzles is in the range from 1 to 3.2 mm. As a rule, a larger disk diameter corresponds to a larger width. As for the circles of small diameter, their thickness can be any, depending on the purpose.
If we talk about aluminum, then for its processing, circles are used with a thickness of about 1 mm. This choice is explained by the alloying of this metal. During operation, the thick nozzle of aluminum becomes viscous from friction and begins to score an abrasive circle with its particles. In such a situation, the disk just stops cutting.
As for the configuration and coating of the cutting part, most often circles for aluminum have diamond fine spraying and cutting edge in the form of several sectors. In fact, this is a saw disk by concrete. It is for them that it is convenient for them to carry out work on cutting aluminum structures. For example, cut a profile. The diameter of such a disc is minimal, that is, 12.5 cm.
Circles of the maximum diameter of 23 cm are most often multifunctional and cut not only metals, but also concrete, plastic pipes and even a tree with nails.
I must say that only by appearance to understand the exact purpose of such a nozzle is almost impossible. Therefore, when buying, it is best to consult with the seller or study the characteristics indicated on the disk itself.
Choosing a grinding circle
In the construction market you can see a wide variety of special circles for various types of grinding and polishing corner grinding machine. There are such nozzles primarily by type of coating:
In addition to abrasive coating on a circle, various pastes with abrasive inclusions are used to grind metal surfaces. Their use depends on how smooth the surface is planned to get. In order to perform black aluminum cleaning, masters use sandpaper with large grains. The structure of the grinding circle should not be dense (with a small number of grains per unit volume of the nozzle). Such work gives at the exit a rather rough surface, which requires cleaner grinding and polishing.
For small and neat grinding, spongy circles are suitable, which can be used along with fine.grained pastes. After them, you can make polishing using interchangeable coatings of felt or fabric, which are fixed on a special nozzle for corner grind. In this case, a paste with minimal grain sizes is used. When choosing a nozzle, the manufacturer’s brand is also important. Products, which should not doubt, produce mainly well.known companies, such as:
If the manufacturer is little known, then there is always a risk of acquiring low.quality goods with poor reinforcement or even without it. Work with such nozzles is dangerous for health.
The skaters themselves note the repetition in the images
The production turned out to be quite successful, the technicality is still at a high level, I want to dance on the rostrum under the musical cut Only one thing can upset-it seems, somewhere it has already been already.
At the premiere of the production of Nastya and Sasha, they spoke a little more about choosing music and frequent use of rock music:
“For Tamara Nikolaevna, this era of rock itself is modern. For her, modern now is rock, therefore, probably, we had three programs in such close styles. And, in fact, I believe that it is right: this style is suitable for us, and it differs from the fact that we ride in short ones ”.
The pair style is really suitable, Gallamov does not even need an electric guitar, as on a show to turn into a rock musician. And in competitions compared to open rental, the production looked better. Even a theatrical afterword appeared-at the Panin-Kolomenkin memorial Sasha, after the end of the music, turned to the audience, allegedly forgetting about the partner, and Nastya at that moment was indignant, lying on ice. Inside the already proven base, the couple uses some new details, and this is beneficial for the program.
A successful pattern is used not only by Mishina/Gallamov
However, other skaters are repeated-three seasons of Kamile Valieva give a lyrical image in a short program, and some common details are traced in the production. The “storm” from the covid season turned out to be very successful and emphasized the winning sides of Camila, so they decided not to risk the Olympic season and now. The junior program of Valieva “Girl on the Ball” is still a mansion-there is a bright image from the picture, perfectly hung on the skater in her 12-13 years, and a characteristic choreography.
Of course, every skater has that zone of comfort, those role in which it is convenient to ride and win due to this. The images of strong female characters have repeatedly passed on the ice Alina Zagitova and Alexander Trusov, and Anna Shcherbakova very organically feels in the lyrics.
In the use of a successful image, the season in the season does not have something bad for skaters: everyone decides whether to try new or put on things, tested by time. Especially when you are world and European champions, winners of the Olympic Games in Personal Tournament and champions in the team. Only it is unlikely that the production near Presley can be called an experiment, as the guys themselves noted on control rolls.
Of course, in such a specific season I would like to see more unexpected transformations, real experiments. games with music, elements, images, in particular, from the same paired skiing that many have long accused of stagnant. On the path of experiments, for example, Daria Pavlyuchenko and Denis Khodykin were followed, but the couple was not even afraid to enter the territory of the unknown. And the program Mishina and Gallamov primarily meets their main goal for the season. to please the audience and win.
On yourself or from yourself
The most common question that torments many owners of a corner grinding of a grinding is “how to cut a corner grinder correctly so that the disk spins from itself or on itself?””. There are many opinions, and everyone proves their own point of view. But the correct answer is one: “You can cut both from yourself and yourself”. Obvious evidence of this is the presence of holes under the handle on both sides of the device. In general, it all depends on individual preferences, to whom it is convenient, he cuts so. However, each method has certain nuances, they should be taken into account.
Many owners of corner grinder do not like and can not even cut from themselves. The bottom line is that this method rarely forgives errors. Any inaccuracy or cutting curve leads to a clip of disk and its rupture. I want to say that I have a friend who is used to cutting on myself, and taking my corner grinding in his hands ditched two discs and gone shouting. This is a person who has been working with a corner grinder for about 10 years. There is also a myth that when you cut it from yourself, when the disk is jammed, the corner grinder will fly away into the stomach. I want to say that if it is normally not holding it in my hands, then it can even fly out of the workshop. The advantage of metal cutting from yourself is that sparks fly from corner grinding and may be better to see the product. In addition, with a disk rupture, it will fly away from you.
Metal cutting at a speed of disk allows you to work with a corner grinder, sorry for the expression, with a slight negligence. But you pay for such convenience sparks flying into the eyes and on your feet. If the protective casing is set incorrectly, then the risk of burning pants increases exponentially. In addition, the product is visible much worse, and when a rupture, the disk can fly under your feet. When cutting metal in this way, I recommend holding the angular grinder so that in the case of jamming and rupture of the disk, the latter cannot get in the leg or other part of the body.
Material cutting is one of the main functions of a corner grinding machine. For this, there are special cutting discs. They were invented to quickly and accurately cut the material with a compact device and do it anywhere. Corner grinder cuts are mobility, ease of use and accessibility.
You need to work the same way as a saw. You turn on the corner grinder, slightly press on the product and after a few seconds it is cut! However, unlike the saw, cutting with a cutting disk, in fact, is the same grinding. Therefore, the total length of the product is reduced, as you remove the material from a certain point. If you take a grinder with a diameter of a couple of millimeters and grind the same place for a long time, you get the same result.
Subtlety is a characteristic feature of cutting discs. They resemble DVD. Subtlety gives them the opportunity to cut products from any material so easily. They are much thinner than all other types of disks for angular grind.
The thinner the cutting disk, the more dangerous it is. Thin discs are easily bent and easier to break. If you work for a workbench with a product clamped in a vice, a thin disk is what you need. But if you are, for example, under the machine in an uncomfortable position, it is better to take the disk thicker (from 3 mm), which will not break if you accidentally move or lose your balance.
With the help of corner grinder, almost any material can be cut: metal, concrete, stone, brick, ceramic tiles and wood. For each material there is a separate type of cutting discs.
R Azdel 10. Execution from the scene of the arc back and down. Rib change. clipping. The main provisions of the free style.
With tart, shown in the pictures 32, a, b, it differs from the start on the edge back and in the fact that you stand your back to the longitudinal axis, leaning in the opposite direction.
|Diagram 7. Conservative arcs back are the attorney. Transition from one rib to another using a spiral. Notice how this differs from the start, from the place|
Stand exactly on both legs, spread them to the sides. NOST HANDS A little to the right, as shown in the picture 32, and. Shift the body weight to the left leg, while raising the right from the ice. Pull the right leg to the left, at the same time move your hands a little to the left (picture 32, b).
Make a semicircular push with your left foot, turning your arms right, hold your shoulder in front. Now you must lean into the circle to push back back and down (picture 32, e). Pull the left leg to the sliding right. and the initial movement is completed.
|Short 32. Consecutive arcs backward|
A common error is shown in the picture 32, and. at the moment of the push, the skater was very much averted to his left shoulder.
Change of ribs. Pulling
So called the transition in sliding from one rib to another. He leaves a wriggling trace on the ice. This movement is made from any rib: if you start from the external, then you finish the movement on the inner edge, and vice versa. Such changes in the ribs are used in all types of figure skating. We will show you the transition from the right forward-will be arranged to the right back and down.
Start as you started to perform an arc forward-arrange. However, in this case, when the free leg goes forward, the left shoulder is pulled back, as shown in the picture 33, e.
You must take this position before approaching the longitudinal axis, and when you find yourself on the axis line, pull your free leg back, and serve your free shoulder forward. Having done this, you will switch to the inner rib.
There is another position when making a transition from one rib to a rib that differs from what is shown in the picture 33, g. It is given in the picture 33, d. In this case, the shoulders do not change their position. And the other way has its advantages.
It is not difficult to carry out this change of ribs, and usually errors are not noticeable until you begin to use this movement in any figure. There, even small errors can be very significant.
|Short 33. Change of ribs|
|Diagram 8. Change of ribs: A- right; b. incorrectly. “oblique” change of ribs; B-incorrectly-s-forming rib change|
The diagram 8 shows how successfully and unsuccessfully the change of the ribs is made. this is clearly visible in the wakes left on the ice. Since in the book we do not talk about various figures, so it makes no sense to delve into details. We will only say that you will perfectly make the change of the ribs, following our instructions, without throwing your free leg up before the change itself, it is only fed, without raising it high.
In addition, do not “deepen” the rib before the change itself.
Keep in mind that the change of rib is instantly; Also instantly change the body position. Do not make incomprehensible movements just a few centimeters before changing the rib. Keep in mind that the change of position is not a change of rib. It’s just that in a modified position it is more convenient and easy to make a haul. But we are already too much in the details. Do how we taught you, and the change of the ribs will take place perfectly!
Rock is second
With about acquaintance with skates and boots, figure skating begins. And therefore, first of all, I want to talk about our inventory.
Before the start of the season, dad and mothers are seriously concerned: where to get the children’s skates? Small sizes are a deficit, because hundreds of thousands of boys and girls want to become skaters. Skates in children’s groups begin to move from one generation to another and are stored carefully and lovingly.
However, it is necessary to monitor your sports equipment in any case, because the speed with which you will master the skills of figure skating largely depends on it. It will take a lot of time after the first.time shoes with skates for figure skating first appear on your feet, and you will already know every fold on boots, every “dash of character” of skates. And when you have to change shoes and skates. the leg grows. parting with them and getting used to new every time it will be difficult.
You have probably noticed that figure skiing boots have high boots. centimeters twenty higher than that of ordinary boots. Such a high boot did not appear by chance, because complex movements on the ice require that the boots, horse and leg make up a single whole. With a short boot, this cannot be achieved, it is necessary that it be at least eight to nine centimeters above the ankles.
The shoa of the skater should be exactly on the leg. With a woolen sock, he sits, as Nikolai Panin-Kolomenkin figuredfully remarked, like a good glove on his hand.
The boot should be tough. But it happens that the new shoes have too hard back and shook his leg. Then the easiest way out is to knead your back with your hands. And so that the leg is not rigid when lacing, under the long tongue of the boot you can put (or pick up) a special gasket. Many experienced skaters under the tongue lay a foam laying.
All this is done so that the legs do not heat up, so that the blood circulation in the legs is not broken.
The color of boots for beginners does not matter. But there is an order by which the skaters ride in black boots, and the skater. white.
You already obviously know that the skaters have your own, not similar to other skates. The skate blade is connected by three racks with the sites for fastening skates to boots. Even in the figure, you will easily notice that the skate blade is curved (the middle part is the most flat, it is most often used by skaters). The curvature of the blade generally is of great importance: the nature of the skiing of the skater depends on it.
Look carefully at the skate blade: it is also unusual. If you look along the blade, you can see that it is not even, but is coated in the form of a groove with slightly raised sharp edges. These edges are called skate ribs. I will talk about them in many classes, since the ribs are of great importance for all the movements of the skater.
The front of the skate, in shape resembling a dilaponous scoop, has several sharp teeth. They are also necessary when performing various complex elements, rotations, stops.
How to pick up skates? At first, shoes are selected, and then already. to them. skates. The correct selection can be done in this way: attach the horse to the sole of the boot. the end of the front site to strengthen skates should coincide with the edge of the radar. If at the same time the lower tooth is also on one perpendicular, then everything is correct. The back platform on the heel should occupy a central place and not go a millimeter for a heel. If there are no skates of the required size, then it is better to choose more for the number than for the number less.
Correct fastening of skates is a difficult matter. That is why the skates are first attached with several control screws, and after the skater tested on ice, fixed to all the screws or slightly shift, if there is a need for this. When the skates are attached incorrectly, it is difficult to stand and move on the ice: it seems that the boots fall out or inside.
The largest figure skating specialist, the American Gustav Lus-Si believes that the skates should be attached so that their blades are somewhat shifted inside from the central line of the boot. He considers this method of fastening skates one of the best, since the ankles are strengthened.
Based on the experience of the work of children’s groups of figure skating, I want to recall once again that when buying boots (their quality often leaves much to be desired), you need to carefully examine the boots from all sides, especially from above and from the side of the sole, because sometimes the boots are uncented, heel, heel Leaned to the side. It is necessary to check the boot of the boot. which should be, as you already know, is solid and well hold the ankle. The skates certainly need to be checked by the racks so that they are perpendicular to the sites, and the blade should not have any bends along the entire length. Extremely carefully use the inventory that is already in use, especially this applies to boots, as they are most susceptible to deformation.
It happens like this: both the horse and the boots are good, and the leg of the young skater is flooded inward or outside. This happens, in particular, with a congenital defect in the feet: if the child is oblique, it is difficult for him to deploy the horse and slide with a “Christmas tree”, and the push to the other foot with a teeth. In this case, you need to look for a convenient option for fastening the skate for a young skater. If the boots are flooded inward, you can also shift the skates a little inside, and if out, then the skates are rearranged to the outer part of the boot.
And one more necessary detail in the sportsman sports inventory: skates covers. Sharp ribs of well.sharpened skates. easily elevated. Even on an ordinary wooden floor, they are covered with scratches, burrs. And in order to protect the skates of the skates, after class, when moving to the locker room, special covers are put on. These covers are sold in sports stores. However, if necessary, they can be made by themselves.
Covers exist for boots. Skiters always make such covers themselves. Woolen socks (shoes selected in the color of the boots) are cut in the center of the sole, buttons and loops are sewn to the edges and fastened under the sole boot. These covers protect the legs from hypothermia.
Rock is fifth
And here we are again gathering at the side of the rink. Before the start of the lesson, a few more minutes, but everything should already be assembled.
We will always start each lesson with the repetition of the passed and learned material, and then move on to unknown, new movements, exercises.
And one more thing: the numbers of the lessons in my book, of course, will not coincide with the numbers of your lessons on the ice, because mastering the tasks of the Book Lesson will require several ice classes. The distribution of tasks is already a purely individual business, and it is important that all tasks are well completed. Because you will not learn some complex movement, because you have not learned more than simple.
Now. on the ice. For starters. ordinary sliding forward. Just sliding. Be attentive to what will happen at the end of the sliding when you put two legs on the ice. Take a look not only at yourself, but also to others. Let’s do the exercise several times, and then get together all together. What did you pay attention to at the end of the sliding when both legs were on the ice? Here you are, boy, what you noticed?
You were twisted at the end of the sliding either to the right or left. Correctly. So it should be. And you didn’t notice anything else? My neighbors also did not see anything unusual? Ah, they even unfolded their backs to the movement! You’re right. This happens, and even very often. And this is completely natural, because it is due to the very design of your skates, and indeed all skates for figure skating. We can say that this is one of the advantages of our sports weapons. About how to use this dignity, we will talk today. But first, let’s recall what you know about the ribs of skates for figure skating. We talked about this in detail in one of the previous lessons.
And now in practice we’ll try to use the properties of our skates, let’s see what it gives us.
Stand on one right leg. Then push off your left and in the third position, slightly tilting the torso to the right side and taking the right hand forward, make yourself drive as long as possible on the outer edge of the right skate along the arc.
Just take your time. The tilt of the body is necessary, do not keep it completely straight. If you do not lean right, and even more precisely. to the center of the future circle that you should draw, the movement in a circle is generally impossible. That is why I asked to immediately tilt the body.
At the same time, you also need to know that the greater the sliding speed in a circle, the more you need a slope, without it it is difficult to resist the skate. When you study the laws of physics, you will learn about centrifugal and centripetal forces. It is they who often act on the skater in various movements. Without tilt inside the circle, movement in a circle is impossible.
And since you just don’t be able to lean inside the circle, the arcs that you are driving will not be very steep, and the initial sliding speed is low. A light push, a small tilt of the body. and you slide in an arc or in a circle without much difficulty.
You have questions? Please ask. So, so, I just expected this particular question: “What is the tilt of the body?»Let’s figure it out.
The tilt of the body should look like this. You bent to the right (or to the left. depending on which direction and on which edge you make an arc or circle). Do not be afraid. Just do not curve your leg in the ankle joint. clear? Well, that’s good. And yet. try not to be skewed.
I understand that it will not work right away that it is not easy to feel the support of the skate rib. That’s why I ask you additional homework. It will not require any additional inventory. This exercise on the wall is performed. There should be shoes with skates on the legs. You lean toward the wall, relying on it with your right or left hand, depending on which direction you are tilt. The body should be straight, in no case do not “break” it.
Repeat this exercise dozens of times. And when you once again go out on the ice, you will immediately feel how much it gave you.
When gliding on the right leg on the outer edge of the skate, the left leg is free, it should be raised by ice, and its toe should be deployed from behind.
The execution of this movement will be very difficult at first. And that’s why. You will either sharply tighten you in a spiral, or, on the contrary, you can’t “lie down” on the arc, because the slope will be insufficient. No need to despair. Check the position of the hands: for an arc on the right leg on the outer edge. in front of the right hand and right shoulder, the left hand and left shoulder are allotted back; for an arc on the left leg on the outer edge. the position of the arms and shoulders is mirror. Now it all depends on your perseverance.
Make yourself tirelessly repeat the unexpected movement. After all, this is how your will also check, your character! And in the end, you will feel. this moment will definitely come, you just need to be prepared for it and not miss it. at what inclination, at what position of your free leg and hands you are most convenient to slide on the edge of the skate. I had already told you what functions perform your hands and body. It is most important for me that you feel muscle and remember forever a position in which the most convenient is gliding on the edge of the skate.
This is a very important touch, which must always be remembered. It is impossible to fix a single movement for a long time if you do not feel the muscles if you do not catch the moment when it turns out for the first time accurately and easy. And then we will still have to learn to regain this muscle feeling that it becomes its own, close, always accessible.
You probably want to know what can still prevent you from quickly learning to slip on one edge, if all my recommendations are made?
The question is natural. I want to immediately pay attention to a free leg. She is the skater, as it were, the steering wheel: with the same tilt of the body with the movement of the free leg, you can tighten the arc cooler or, conversely, make it very gentle.
What is the standard position of the free leg, in which sliding on the edge on the arc is the most successful? The leg should be pulled back, expanded with the toe and be over the following or a little side of the trace that you pave. In this case, the free leg should not cross the trace.
You do everything right. Just don’t forget how to hold your hands and shoulders. When gliding on the right outer edge of the skate, it is necessary to put forward the right shoulder and right hand forward, and the left hand and shoulder should be taken back. Fix this position. Get used to it, although at first it will be uncomfortable and unusual.
How to cut an aluminum profile
Aluminum profile cutting technology depends on the technical parameters and the volume of work. If the work is not enough and the material is not thick, then you can use improvised tools.
You can learn more about the variety of profiles on a specialized site.
When it is necessary to make many cuts on thin aluminum and you need to do this regularly, it is better to choose a more serious equipment. Also, the choice of suitable equipment depends on the type of cut, straight or cut along the curve.
There are various types of cutting aluminum profile using such equipment:
scissors and hacksaw for metal; electrician and electrician; corner grinder; milling installation.
Features of cutting by electrician and electrician
With the help of modern electrolobesis, you can easily perform various cuts in metal sheets. But this tool is used when cutting a small aluminum thickness.
Each master, using an electrician, can cut the corners and make a figure cutting of metal. For the cut of aluminum sheets, it is necessary to use lobe with high power.
With small volumes, you can use electrician. They have high accuracy of the cut and can perform curved cuts without curving the aluminum profile.
The lack of such a tool is the possibility of cutting only from the edge of the metal sheet. If you need to start work from the point inside the sheet, then it is better to use the cutting scissors for metal.
The most suitable cutting tool
It is extremely important to arrange when cutting aluminum protection against shavings. The fact is that, regardless of the cut (straight or figured), chips can cause significant damage to the master.
To prevent them from happening, the tool should have protection against chips, and the master. by personal protective equipment: special clothes gloves plastic glasses.
The implementation of an aluminum cut
The bottom line is that aluminum is a rather soft metal. If we are talking about a large thickness (aluminum slabs), it is recommended to act as follows. Using a cutting tool along the cutting line, it is necessary to carry out several times.
Only in this way it becomes possible to cut off the metal evenly and qualitatively. Otherwise, when cutting in a “one sitting”, an active organ of a cutting tool may get stuck in the metal.
In the worst case, this will lead to the grass of the worker. In the best. the metal section will be technologically disgusting and will require additional processing. And this is an increase in time.
At the same time, do not forget that it is recommended to apply oil, paraffin or aviation kerosene to the place of the cut. This will avoid overheating of metal in the cutting area.
As a result, a perfectly even cut will be obtained, regardless of the configuration. Thus, thanks to the qualitative approach and the use of a specialized tool for cutting aluminum sheet/stove, it becomes possible even in a garage workshop.
The video will demonstrate the use of various BOSH files for aluminum cutting:
