Polishing with a grinder. Is it possible to polish a car with an eccentric grinder

Greetings friends on our website Car repair in artisanal conditions. Today, the car is not only a means of movement, at the same time an indicator of social status and respectability of its owner.

A pleasant color for the eyes, the ideal shape, a brilliant, completely smooth surface. Such properties serve as a subject of pride for their own “iron horse”.

But the machine is not a decorative product that is stored only in suitable criteria, where it does not threaten the renunciation of the deterioration of all properties.

The environment of the car is an open place with complete negative influences, including both the weather changes and a huge number of anthropogenic and other reasons.

Traces of washing is not uncommon, scratches purchased with inaccurate loading or from branches of trees, chips, stains, to be just spoiling the mood of the car owner.

However, there is an option to correct the situation by resorting to polishing. The process, the result of which is the reconstruction or restoration of the coating.

However, not all owners of the car decide to carry out a similar process without the help of others, but trust only specialists from the car service, and think that they only know how to politely polish the car.

In reality, any of the car owner will do this at home, you only need to follow the main rules, and of course listen to advice and tips.

Polishing is carried out not only for cosmetic purposes, this is also a technique that protects against damage to enamel leading to the formation of rust. In addition, if there is such a need to polish headlights and there are car glasses.

The coating of the car of the bulk of the surface of the body prevents the corrosion process, but the paint is quite simply covered with small cracks.

Specifically, different substances penetrate into such insignificant disadvantages that launch, as it were, an inconspicuous, but rapidly progressive process of corrosion.

The prerequisite for this is the mud and dust, who own abrasive qualities, which in the absence of an overwhelming care leads to an inconspicuous state.

Additionally, a direct negative effect of sunlight for a long time can reduce the radiance of the car surface for a long time.

Of course, the work on polishing the car is conditionally divided into four steps:

First you need to prepare not so much the car, but the room where polishing is performed, for reasons of 3 criteria: lighting, space and purity and cleanliness.

Because they will be polished that it remains to make our client a part of the car and the upper and lower ones because it is better to install not poor lighting in the garage.

It is also better to take out an excessive one from the garage, freeing a place for the car given that the doors will have to be opened from 2 sides. Then it is necessary that it remains to make our client to accommodate and sprinkle the floors well with water.

The car must be painfully washed and wiped dry with a hygroscopic lip. You should not use the villous in another silk matter.

After washing, it is recommended to remove oil, resin spots, the remains of the budon, treating the surface with an alcohol.Containing solvent, for example, “White Spirit”.

To polish the car on your own, subsequent tools will come in handy:

  • Rubber gloves;
  • Circles for polishing;
  • Soft, but dense pieces of rubber;
  • Sandpaper paper;
  • Bucket or other water vessel;
  • Scotch;
  • Polish.

Why is it impossible to polish with a corner grinding (my opinion) what is the difference between a corner grinding and polishing

If you say, your car was painted, then polishing begins with grinding using sandpaper with a grain index of 1.5-3 thousand, depending on the purchased shagings.

There are two types of grinding. Dry on wet, the difference in which is without or the presence of water during operation.

With dry grinding, you do not have to waste time on drying, but such a method asks for an overrun of the sandpaper, because it is rapidly clogged.

For which the design of wet grinding is designed by the paper is often washed with water, for the ability to see the result of the work, the part must be dried.

The question of what method of grinding will be used to solve in advance, guided by purely personal preferences.

After grinding, you need to go through the details of the rubber segment, wrapped in a skin. This shakes shagrin, will also remove the remaining garbage; Then the part is cleaned without rubber.

The main this process is not to overdo it, a layer of painting will be pulled differently, especially acrylic, and the part will need to be painted again.

A similar inconsistent often appears at one time of indistinguishable cleaning of the ends, therefore it is more perfect only a few times to spend on them with sandpaper.

The dried cleaned part must become matte without signs of varnish shine; It is better to get the detail on dry, because it is not appropriate to wet it again.

In this case, the grinding of a painted car ends, you can proceed to the main step. Polishing.

In addition to the often questioned question, how to polish the car, two or more more and more produced is the question of the better to polish the car?

Polishing the machine is carried out using a special polish. Measured emulsion or pasta, resistant to separation and external influences.

How to buff, polish and Wax (the Auto zone way)

For clarity, polishes are divided into three main categories:

There are a huge number of different polishes for mechanical processing, but in the bulk they use strongly ambizer, medium.Meaningly understanding restoration polishes.

The highly ambitious polish erases the unusually screaming layer of the coating, therefore it is recommended to use it only in the latter case.

The medium.Ababral polish removes the insignificant layer of locusts and is used in the presence of insignificant, small scratches on a car.

The restoration polish returns the original color by light removal of paint, usually it is used more than 2 times during the year. Already today, there is a universal tool that combines the characteristics of all types of “mechanical” polishes.

How to polish the car at home

Naturally, by home conditions you need to mean a dry, well.Lit garage. It is impossible to polish a car on the street or in the yard even with a warm summer. Dust brought by the wind, fallen leaves will instantly spoil the results of your work. It is important and uneven drying in the sun of many types of pastes and a polyter that affects the quality of work, a general view of the machine.

Preparatory operations

The garage must be removed before work, getting rid of dust as much as possible. Experienced car mechanics do not advise polishing the car at minus temperatures and in the heat (over 35. 40 degrees). Before starting polishing, a number of preliminary operations are required:

  • Body washing (manual or contactless);
  • Removal of spots and strong pollution (oil, bitumen);
  • Pasting decorative details (chromium, nickel, rubber, plastic);
  • Inspection of the clean body (the selection of abrasives, grain of polishing compositions depends on the degree of damage).

If you have no place or conditions for an independent car washing near the garage, you can visit a car wash right before polishing, better contactless. Having drove into the garage, you need to wipe the car again with a clean dry rag.

After washing, the beam spots, oils, which are removed manually, soft solvents, degreasing, white spirit, are clearly visible. In this case, do not use screwdrivers and knives. By soaking the speck, it is easy to remove it with a fingernail or plastic card.

In order not to damage the decorative elements (edges of the glasses, moldings, mirrors), they are glued with painting tape. Professional polishers also remove the nickels of the door handles, but to beginners at the first experiments, it is not recommended to do this.

Experienced lovers of independent work with the machine, simultaneously with the polishing of the body, polish the glass of the car. Technologically, the operations differ little (only by the compositions of pastes and protective equipment), having gained experience, you will be able to polish the glass yourself. At the first attempt to polish, it is better to seal all the glass.

Restorative abrasive polishing of the body

Before polishing the car with your own hands, you need to take care of the tool and consumables. There are two methods of abrasive elimination of damage to the paint and varnish layer. Manual and mechanical (using a grinding machine). Experts advise starting lovers of independent work first to try their hand at manual abrasive polishing, requiring less material costs.

For manual grinding of the LKP you will need:

  • Abrasive grinding skin (P-20000, R-2500);
  • Water sprayer;
  • Special napkins or cotton rags;
  • Polishing paste and polishes.

Operations of abrasive grinding of the body

Before use, a grinding skin is cut into small pieces and their edges are rounded so that sharp corners do not leave deep scratches. Manual grinding begins with a small section of the body, subsequently moving from it in different directions. Before grinding, the surface is wetted with water from the sprayer.

The paint soaked with a skin is polished in two perpendicular directions, achieving even matte color of the LKP. The process is repeated several times, wiping the water with a damp and dry rag. After the R-20000 skark, the second grinding can be carried out with the Skewon R-2500. After that, with a fine.Grained sponge or plastic card, a polishing paste is applied to the polished area and with effort they are rubbed with a circular movement with special tampons or napkins.

Polishing after grinding will accelerate significantly if you use a grinding machine. Instead of a machine, you can use an electric drill with a special nozzle (only drills with adjustable speeds are suitable).

For mechanical polishing, you will need to add the following tools to the original set:

  • Grinding machine (with adjustable turns from 700 to 3000);
  • Protective glasses;
  • Grinding and polishing discs;
  • Mandrels for fixing disks of various thicknesses;
  • Felt or fur polishing circles;
  • Hard brush for cleaning circles.

In the process of mechanical polishing, the machine is carried out in circular movements. They begin work with small revolutions, making efforts to rub the polishing pasta. In the future, the turns are increased, reducing the squeezing force. Begin work with pastes of greater grain and hard circles. According to the results of polishing, they are sequentially changed to softer circles and pastes with low granularity.

The work of the grinder requires worked out skills, so before the start of polishing the car body, you can practice on the removed body part. If the pastry is incorrectly selected, the rotation of the disk and the effort of pressing the automobile enamel can be erased to the metal, burned (rainbow spots of runners appear, the paint swells). Excesses of the body, figured stamping on the hood, wings, doors that need to be polished especially carefully are especially responsible places.

Car for polishing and grinding vehicles

The body of the machine in proper condition requires constant care of the body. In addition to regular washing, the car is necessary timely body repairs to eliminate minor defects. To facilitate grinding, reducing the time of work and improving quality, a polishing machine for a car is used.

There are a large number of body repair machines, with which you can polish. To improve the quality of work, and at the same time do not erase the paintwork completely, you should choose the suitable machine and take into account the features of the tool when working.

How to choose a polishing machine for a car

When choosing a polishing machine for work, it is necessary to take into account the power and principle of operation of the device, the number of direct surfaces and seams, inaccessible places on the car, the type and thickness of the paint and varnishes, the number, depth and density of minor defects on it.

By type, polishing cars are divided into:

Each model has its own characteristics and advantages.

Disk cars

By appearance and principle of operation, the device resembles a corner grind. A disk.Type car grinding machine is an inexpensive and highly effective tool. The type of spindle rotation allows you to work at large angles, but requires accuracy. It is not recommended to use such a machine for a thin layer of paint. Professional disk grinders differ from the corner grinder with a diameter: for a “home” work with a personal car or a small metal surface, an angular grinder is suitable for radius 125. The device is professionally used by a radius of 185-205.

Among the domestic manufacturers of grinders, Interskol should be allocated. Its tools are great for completing problems of medium complexity, so they are often used by car deles to polish cars.

Orbital cars

The tool is more complicated than disk devices. The cost of an orbital polishing machine for a car is the same power higher than for a disk.

The device is a sole to which the disk is attached. During operation, in addition to rotation of the disk, a progressive movement is performed that moves it along the sole.

The orbital machine is in great demand and is considered the best tool among professionals than other types of polishing devices. Due to the progressive movements, the speed of work and the area of ​​the simultaneously processed surface increases. In addition, the device determines less surface heating, therefore, when working with an eccentric machine, the paint does not burn out and it is better preserved. It is more expensive than other devices, but professionals recommend this type of tools.

Ribbon

Performs grinding due to the movement of a looped abrasive tape. Used to remove paintwork from flat surfaces of large area. The use of such a device is justified, but will require additional equipment to access the operator to hard.To.Reach areas. Used for rough processing before painting.

Vibration and deltas.Grinding

The machine is a sole with an abrasive coating. Provides neat and high.Quality treatment of small surfaces. Vibration machines for polishing the car body are quite heavy and poor for large planes, but work excellent with uneven surfaces.

Deltas.Grinding devices function on the same principle as abrasive, but their sole has the shape of a triangle. This further reduces the area and speed of work, but allows you to get to the most inaccessible places. Professionals use this type of tools for grinding seams, defective surfaces and other natural and acquired irregularities.

What else can be polished

In addition to professional electrical tools, hand.Made tools for polishing the car and improvised means are used to polish with your own hands. Hand tools include shirts and sandpaper. To this method, they resort to if necessary to perform high.Precision work on small surfaces. These funds are more often used at home, in the absence of deltas.Grinding device.

Improvised means. Multi.Purpose tools that can be used, including for grinding metal surfaces. These include:

Devices perform the same functions as professional machines, but with less efficiency, therefore they are used exclusively at home for lack of specialized tools.

Plane

Specialized manual tool for processing wooden and steel surfaces. The rubbish is used to grind the car in the event that high.Precision processing is required. The skin of fine granularity is fixed on the tool, after which the specialist makes smooth progressive movements on the surface. Such processing removes unevenness, but causes minimal harm to the metal. The quality of the operation depends on the number of grinding directions: the variety of trajectories of movement makes the surface more smooth.

Corner grinder

The tool is an analogue of the disk grinding machine at home. Motorists come to the polishing corner grinding after receiving small defects on the body by the machine. Compared to a professional machine, the angular grinder has a smaller radius of the circle and, as a result, less efficiency, but copes well with small defects.

To eliminate small defects, a foam or woolen disk and pasta for applying to the tool. It is important to use a corner grinder with the adjustment of speeds and modes, as well as an electronic system for maintaining revolutions under load in order to avoid even greater damage to the car.

Protective polishing of the paintwork

After processing by abrasives, the restoration polishing pastes, filling the microzarapins, align the surface of the automobile enamel, correctly reflect light rays, which gives the paint a mirror shine. But restoration polishing does not protect the body from new damage. To prevent minor damage to the paint, protective polishing is intended.

Producers produce protective polishes based on:

Before choosing a polishing paste for protective polishing, you need to carefully read the instructions for use. Some of them can be applied to the car manually, others require the use of a grinding machine.

The principle of operation of protective pastes is the same. They create a thin layer on the paintwork that protects the enamel from ultraviolet radiation (the paint burns out less), repulsive water, dirt, chemicals.

Simple soft pastes include wax compositions, which can be manually applied to the body and grind with a special napkin. A car owner can apply a preventive defense to the car body in an hour, but a soft paste withstands only two to three contact sinks.

Silicone.Based polishing protective pastes, Teflon are more durable. They withstand 30. 40 sinks, but you need to polish the car with a grinder with interchangeable nozzles. The polishing technology is similar to abrasive, but requires an accurate exposure of time depending on the drying of the protective composition.

In more expensive nanocramic protective polytheurs, the hard external layer create polymerized compounds containing the smallest crystals of silicon dioxide, titanium oxides. The polymer ceramic layer fills the irregularities of the paint, delays microcracks, protects the enamel from peeling. The protective properties of nanocremics increase depending on the applied layers of the polytheur (use up to ten layers). Professional polishers highly appreciate the politicians Ceramic Pro, Nano Polish, Ceramic Pro Light, Restor FX. Determining the effectiveness of protective polishing is quite simple. If you pour a water coat on the hood of the machine, the liquid will gather on the surface in large drops.

The compositions under the domestic name “liquid glass” contain plastic solutions of silicon dioxide, sodium silicate, which when solidified fill the microsyas and uneven enamels. The mirror layer of silicon compounds obtained from quartz sand, harder than car paintwork, therefore becomes reliable and durable protection of paint. After the end of polishing, the car should not be washed for about two weeks, until the protective layer is completely hardened.

Having independently made abrasive restoration polishing, polishing the car with strong protective compositions, you will return the car to the car not inferior to the new car. Protective polishing operations that need to be repeated once. Twice a year, will reduce the need for abrasive recovery.

How to polish the car at home

Naturally, by home conditions you need to mean a dry, well.Lit garage. It is impossible to polish a car on the street or in the yard even with a warm summer. Dust brought by the wind, fallen leaves will instantly spoil the results of your work. It is important and uneven drying in the sun of many types of pastes and polytheur, affecting the quality of work, a general view of the machine.

6 Useful Drill Machine Life Hacks

Experienced lovers of independent work with the machine, simultaneously with the polishing of the body, polish the glass of the car. Technologically, the operations differ little (only by the compositions of pastes and protective equipment), having gained experience, you will be able to polish the glass yourself.

Restorative abrasive polishing of the body

Before polishing the car with your own hands, you need to take care of the tool and consumables. There are two methods of abrasive elimination of damage to the paint and varnish layer. Manual and mechanical (using a grinding machine). Experts advise starting lovers of independent work first to try their hand at manual abrasive polishing, requiring less material costs.

For manual grinding of the LKP you will need:

  • Abrasive grinding skin (P-20000, R-2500);
  • Water sprayer;
  • Special napkins or cotton rags;
  • Polishing paste and polishes.

Operations of abrasive grinding of the body

Before use, a grinding skin is cut into small pieces and their edges are rounded so that sharp corners do not leave deep scratches. Manual grinding begins with a small section of the body, subsequently moving from it in different directions. Before grinding, the surface is wetted with water from the sprayer.

The paint soaked with a skin is polished in two perpendicular directions, achieving even matte color of the LKP. The process is repeated several times, wiping the water with a damp and dry rag. After the R-20000 skark, the second grinding can be carried out with the Skewon R-2500. After that, with a fine.Grained sponge or plastic card, a polishing paste is applied to the polished area and with effort they are rubbed with a circular movement with special tampons or napkins.

Polishing after grinding will accelerate significantly if you use a grinding machine. Instead of a machine, you can use an electric drill with a special nozzle (only drills with adjustable speeds are suitable).

For mechanical polishing, you will need to add the following tools to the original set:

  • Grinding machine (with adjustable turns from 700 to 3000);
  • Protective glasses;
  • Grinding and polishing discs;
  • Mandrels for fixing disks of various thicknesses;
  • Felt or fur polishing circles;
  • Hard brush for cleaning circles.

In the process of mechanical polishing, the machine is carried out in circular movements. They begin work with small revolutions, making efforts to rub the polishing pasta. In the future, the turns are increased, reducing the squeezing force. Begin work with pastes of greater grain and hard circles. According to the results of polishing, they are sequentially changed to softer circles and pastes with low granularity.

The work of the grinder requires worked out skills, so before the start of polishing the car body, you can practice on the removed body part. If the pastry is incorrectly selected, the rotation of the disk and the effort of pressing the automobile enamel can be erased to the metal, burned (rainbow spots of runners appear, the paint swells). Excesses of the body, figured stamping on the hood, wings, doors that need to be polished especially carefully are especially responsible places.

Using manual tools. Rubank

Rubanok is considered a manual instrument for the body’s body matting. On the device, the skin of fine granularity is fixed and the master begins to make smoothing movements on the surface in any order. The more diverse the trajectory of movement, the higher the quality of the grinding.

When processing a car body, it is recommended that you use sandpaper or scotch-brait with your hands. In this way, areas with a complex relief matte, movements should also not be of the same type.

Grinding machine for polishing the car body

The car for polishing the car is designed to do the work performed without it manually, however, automation of polishing and grinding processes gives additional advantages. The use of the reserved tool allows you to start processing the paintwork with fine.Grained abrasives, which significantly reduces the risk of wiping the layer of varnish through, spoil the surface of the body with uneven processing, etc. However, in addition to the advantages of this method of polishing, there are nuances directly related to the nature of the work and the parameters of the grinder.There is a common misconception about the difference between the corner and ordinary cars for polishing. The corner can only be grinding, and its variety, designed to polish, is a polishing machine. T.E. In the equipment intended for polishing the body, the axis of the disk is always at right angles to the main axis of the tool. On the opposite side there is usually a handle. This does not mean that you can only polish a car with an angular grinding machine: you can do this anything, including a regular drill, but such a corner, the location of the circle axis is much more convenient (the correct distribution of the load and the low center of gravity).

The main parameter of the machine is turnover. To start polishing the car, you need to get at least 1200 revolutions a minute, and for high.Quality polishing up to 3000. When choosing, you need to pay attention not only to the speed range, but also to the smoothness of the launch and the possibility of adjustment. Revolutions can be manual and electronic. It is better to opt for the second option.

Do not be seduced by the ability to work without a network. The body polishing is a long process, and the standard battery is enough for about 10-15 minutes. The presence of a battery increases the cost of the tool by several times, so it becomes easier to find a good adapter to it. It is worth paying attention to the features of the use of circles: some polishing tools cannot use the entire range of polishing circles. Saving on this parameter is not the best option.

Polishing technology with a grinder

The work of the tool is largely similar to polishing with your own hands, but most of it is performed automatically. You need to carefully monitor this. The processing of the car begins with the installation of the desired polishing circle and the acceleration of the device to 1200-1500 rpm. Then the disk is simply pressed to the surface of the body and moves along its plane. The process requires constant control:

  • Uneven pressure is more dangerous than strong (leads to uneven removal of varnish).
  • Strong pressure is more dangerous than weak (it can cause a strong eraser of the LKP).

The car body is heated in the process of processing, so you can’t stop in one place. Local overheating can lead to cracking, exfoliation of varnish and paint, so you need to carefully monitor the heating. The high speed of the car for polishing the car leads to rapidly clogging circles. It is necessary to periodically change them so that the remnants of the LKP do not spread over the surface of the car. Periodically, you need to turn off the tool and carefully inspect the processing site, remove the dust formed with wipes, while wetting the surface with water or purifying liquid.

Polishing is carried out with fine.Grained abrasive, but even ordinary dust can come as such. For this reason, as well as due to heating the car during its polishing, processing should be carried out in a closed room protected from dust and sunlight. When heated above 90 ° C, acrylic enamels can lose their shine completely, and when grinding a car under the sun, such heating is not uncommon.

Nuances of operation

When working with a grinding tool, it is not always possible to guess the initial number of the abrasive, especially since most of the nozzles have their own features of operation. It is recommended for a start to prose the soil, t.E. Test a solid substrate and medium.Grained paste. Local processing of a small section of the car will show what to change: a substrate or paste.

Grinding machine and car tool

The nature of the work of the tool can also vary, especially when it comes to applying a polishing pasta to the body. The polishing properties of the machine are regulated not only by speed of rotation, but also by pressure. The same abrasive can be achieved by the removal of a small layer of LKP, and pure polishing. At the final stage of processing, the pressure on the tool should be reduced and its movement on the surface of the car should be reduced. It is also worth considering the following points:
