For grinding and polishing surfaces of concrete, stone, granite with angle grinder concrete grinding disc. The bits have very strong diamond segments which allow easy removal of stones from workpieces with a stony structure.

The grinding wheel consists of a metal body (disk), which is a cup, so this equipment is also called a diamond cup. Working surface is the edge of the disc, on which the abrasive segments of diamond grit are located. they can go in a row one after another or in a chaotic order. The height of the segments ranges from 3 to 8 mm. They are firmly bonded to the worktool surface, as they are made by soldering. Single-row and double-row grinding wheels are available. The latter have a large working surface, so the impact on the material is the most intense. The body of the cup has holes for natural cooling during grinding.

There are also wheels for finishing stone. these are polishing nozzles. They are flat and have diamond tips over the entire surface. They are mainly designed for wet polishing, i.e. they require water in the work area.

Area of application

Concrete milling is quite aggressive and is used in the following cases:

The milling machine is suitable for removing layers of concrete, paint, glue, from surfaces.

  • levelling the concrete surface;
  • Removal of the top layer of the monolithic slab, foundation or floor above the required level;
  • Removal of the old polymer coating, or laid with violations of the technological requirements;
  • removal from the concrete surface of linoleum or tiles laid on the adhesive;
  • Removal of the reinforced outer layer of concrete (topping);
  • Cleaning of contaminated surfaces from stains, adhesives and adhesives of all kinds;
  • on the pedestrian areas the device of anti-slip zones. Treatment of pavement to improve surface adhesion to vehicle tires on ramps and off ramps;
  • as a preparatory procedure prior to the application of various materials that increase interlayer adhesion on concrete.

Concrete floor milling provides a smoother surface with increased adhesive properties. In addition, the use of this technology can eliminate the creation of additional screed in the construction of concrete floors, which can reduce material consumption and lower financial costs.

The disadvantages of this type of surface treatment are the high level of noise (about 90 dB) and the large amount of dust that accompanies the operation of the machine. This must be taken into account before starting the process. It is unacceptable to work if there is reinforcement in the upper layers of concrete, as the milling process can damage the torsion shaft on the cutting tool. To avoid this, the reinforcing layer must be removed from the surface. Only after that can you start processing.

Types of power units of milling machines

There are three types of engines available:

  • electric. Equipment with an electric motor is characterized by the maximum ease of use, because it does not emit exhaust gases and has a low noise level. These machines allow you to work indoors and in other poorly ventilated places. The disadvantage of the technique is the need to connect to the electricity grid, which reduces its autonomy and mobility. Electric motors installed on milling machines can be powered from single-phase (220 V) and three-phase (380 V) networks;
  • petrol. Such equipment often exceeds the power of electric and allows you to handle large areas. It is characterized by high autonomy of operation and unpretentious maintenance;
  • diesel. The most powerful and productive machines. Typically used on large jobsites. roads, airfields, warehouse terminals, etc.

Concrete milling: tool selection, technology

Concrete milling is the process of removing the top layer of pavement using special milling machines. Due to the fact that the concrete base is durable, dense and reliable, this type of floor arrangement is currently the most popular. And for its processing certain methods and tools are used.

The principle of removing the layer by milling consists of the impact of the drum and cutters to a certain depth of concrete, which allows you to remove at one pass about 3-8 millimeters of layer. Concrete milling is performed by special machines, which greatly facilitate, simplify and accelerate the task. The machine is operated with a drum, and the concrete is sprayed with a wide range of different cutters.

Machines help to remove various irregularities, defects, remove a layer of desired thickness, give the concrete surface the desired characteristics.

The need for concrete milling

Concrete floor milling can be useful in various situations, for example milling freshly laid or previously used floors, in rooms of different functional purposes, for preparing the concrete for the finish coating, etc.д.

  • If the need to lower the level of the concrete screed. if the project involves any changes or has already been cast once the floor is too high and you want to lower the level for the production of poured floors of polyurethane or epoxy resin, for example
  • To get a good horizon. when the old floor is uneven or mistakes were made during the execution of the floor screed
  • To remove bumps from the surface. to reduce the consumption of tile adhesive or materials when installing polymer floors (polyurethane or other substances)
  • To remove old polymer coating. when grinding or chipping by hand is too labor-intensive and ineffective
  • When a certain degree of roughness needs to be given to a floor. in order to improve the adhesion of materials (concrete base and certain types of finish coatings)
  • To make a slope on a flat surface or to increase the angle of the existing base (to create a water drain in car washes, car repair shops, showers)
  • When it is necessary to cut technical depressions of relatively low depth. it has been proved that milling of concrete floor in this case is more effective than cutting of sectors with angle grinder or cutter followed by slotting with bailer, perorator

Applications

Milling of concrete floors often becomes a necessary step in the execution of repairs in apartments, houses, industrial buildings, airfields, car dealers, car washes and other premises. The procedure allows you to solve a number of important problems.

Where concrete floor milling is used:

  • In residential and non-residential premises, where it is necessary to level the surface
  • Where it is important to remove the top layer of the foundation, floor, monolithic slab to lower the level
  • When removing old polymer coating or what was laid improperly and poorly
  • In rooms where repairs are carried out, in order to clean the surface of glue, adhesives, stains for the purpose of subsequent treatment
  • In industrial areas where it is important to ensure a high level of adhesion of the concrete base. the base is roughened
  • On pedestrian areas of roads to form anti-slip zones, on road surfaces for the same function

milling allows you to quickly and easily perform cleaning, leveling of concrete surface, making it rough or smooth, remove old layers of materials, prepare for the subsequent performance of the finish finish trim. Thanks to high-quality and fast processing it is possible to save time and effort, as well as money, reducing the consumption of materials for finishing.

Repair, dedusting, grinding of the concrete floor

If you need to repair the concrete floor, then you can not do without the milling machine, which will help to make the surface of the base flat, remove depressions and corners, any irregularities, defects.

If you want to grind damaged joints, use an angle grinder with a diamond disk: the joint widen, making its edges perpendicular to the floor, then clean the place of debris and dust, primed the surface of the seam, fill it with cement repair mortar (preferably add polymers), wait for curing and grind.

Grinding is usually performed with a grinder, in the process of leveling the base and making it smooth for further finishing. dusting is carried out with special compounds, which exclude further appearance of dust. You can also paint the concrete floor.

Machining technology of the milling machine

Concrete milling is carried out by special milling machines with cutting diamond segments. The surface is milled with a drum with star tools. The principle of operation of the machine is simple. the drum rotates, on its transverse axis there is a centrifugal force, under the pressure of torque the cutter is ejected, which hits the surface of the concrete and affects it in a certain way (cuts, stabs).

The higher the impact force, the thicker the layer is removed in the milling process.

Modern high performance milling machines allow you to process large areas, to work with specific and complex surfaces, which becomes possible due to the variety of cutters. For concrete processing the ordinary cutting diamond discs and milling cutters of a special design with diamonds set on the ends or with helical segments, which are soldered on.

Equipment and tools

Before you start working on a concrete floor, you need to choose milling equipment, appropriate cutting tools. To do this, it is advisable to first determine the range of tasks and requirements, and then look for equipment with the right characteristics of power, processing depth, width of passage, motor type, etc.д.

Types and designs of concrete milling machines and cutters

All concrete surfaces are characterized by high strength characteristics and high density. However, not always after the concrete floor is poured, it turns out quite even and smooth. To obtain perfect flat surfaces in the construction industry, specialized equipment is used. milling machines, which have a special milling machine for concrete. Thanks to these tools it is possible to level a floor in a few minutes, a platform on a country site and any other surface. After milling concrete, it not only becomes smoother, but also increases its adhesive properties.

The sphere of application of this construction equipment is quite wide, let’s consider it in details.

In which areas of application

Concrete milling is an aggressive mechanical action that is necessary to:

  • Partial and complete leveling of concrete surfaces for subsequent installation of flooring (linoleum, parquet, laminate, tile). In this case, there is no need to perform an additional screed, which saves a lot of money.
  • Removing the top layers of monolithic slabs or foundations if their height is greater than required.
  • Removal of small layers of old or improperly laid coatings (magnesia, polymer, etc.).
  • Removal of tiles or linoleum that have been previously laid on the concrete base.
  • Removing peeling cement-sand screed.
  • Removal of toppings (hardened outer layers of concrete).
  • Cleaning the concrete site of dirt, stains, glue, paint and adhesives.
  • Roughening concrete in industrial applications.

Concrete cutter can remove layers from 1 mm, which is often necessary in residential and industrial construction. The only drawback of such processing is the increased noise level (about 90 dB) and the enormous amount of dust. But in view of their speed and efficiency, you can live with them.

Before you buy or rent a concrete milling machine, it is worth to understand its design features.

Machine design

Aggregates of this type consist of the following parts:

  • A welded metal frame with handles, mounted on rubber chassis;
  • engine;
  • A drum-type rotor with cutting elements (this is, in fact, a concrete cutter).

In turn, the drum consists of 4 or more axes, each of which has blades interspersed with washers for adjustment. Cutter is fixed inside the machine on the shaft and can be easily removed for cleaning or replacement if necessary.

The principle of operation of a concrete milling machine is that the centrifugal force occurs as the drum rotates. The rotating cutter blades are ejected by the torque and hit the machined surface with force, removing unwanted layers of concrete. The faster the drum rotates, the harder the impact, and thus the thickness of the removed layer.

Speed and working depth depend on the engine power and size of the unit. When it comes to milling machine varieties, only single-rotor models are suitable for concrete.

Single-rotor milling machines

These models are more suitable for private construction, when the area of the surface to be treated does not exceed 450 m2. When choosing such a unit for milling a concrete floor or other substrate, you should pay attention to the dimensions of the blades. The single-rotor milling machines have a diameter of 0.3 to 1.2 meters.

If you choose a machine for machining a complex surface with lots of bumps, it is better to prefer smaller units. With their help, processing will be much faster. In addition, such machines are much cheaper than their bulky counterparts.

Machines of this type are equipped with special protective guards, on top of the machines are installed control knobs, with which you can adjust the speed of the drum.

cutting elements of machines, selected according to the type of work.

Types of cutting tools

Fragile, hard, elastic or solid substrates may have to be machined. The equipment should be selected on the basis of the following recommendations:

  • The standard cutter is a versatile tool that is recommended if you want to roughen the surface, prepare an edge or remove large protrusions or paint.
  • “Trefoil” is suitable if it is necessary to increase the volume of concrete to be removed. This significantly increases the efficiency of the equipment. Trefoil blades also do the same job as a standard milling machine.
  • For precision work, it is better to give preference to the tool, equipped with a punching rod cutting elements. They are made of special steel. These knives are suitable for removing varnish, paint, scraping and smoothing floors. They are also used for removing rust from steel surfaces.
  • Circular cutter should be used for large areas and when shaping edges.
  • For removal of large irregularities, 2 to 4 mm in height, or when removing screed, it is better to use carbide blades. Grinding is required after such processing.
  • To get rid of small irregularities (up to 2 mm) and cement mortar, it is better to use a mosaic-sander with corundum or diamond cutting elements.
  • Steel or nylon brushes are used for cleaning.

Which motor to choose

Milling machines are available with gasoline, electric and diesel engines.

electrically powered 220 or 380 V machines (power units) are best suited for indoor surface treatment. They are more mobile and do not emit carbon dioxide as opposed to gasoline or diesel-powered models. However, they require three-phase power to operate, which eliminates the possibility of using them in the absence of electricity or the possibility of connecting to a transformer.

Concrete milling machines

Concrete milling machines are the most practical and effective solution for removing 5-7 millimeters of concrete pavement.The diamond cutters (blades) are the fastest way to get the job done.

Concrete milling machines are widely used for rough levelling or removal of concrete or asphalt layers, for subsequent application of finishing coats, such as laminate, parquet, linoleum, plastic and commercial coatings.Concrete milling machines are equipped with gasoline or electric motors for 220 or 380 V, and the processing width of these machines for the removal of concrete up to 250 mm.Buy cheap milling machines on concrete in our company with delivery throughout Russia.

Concrete floor milling

Contrary to popular belief, concrete floors can be very beautiful and decorative. If we consider the concrete cover in a cut then, from the top layer to the bottom, we can observe the appearance of particles of sand, gravel and crushed stone of different fractions. the upper layer is characterized by complete absence of inclusions and by removing a thin layer of coating, the floor will have a flat mat surface. By removing a deeper layer can be obtained coating with small inclusions of sand, then gravel and gravel of medium fraction, and very decorative, reminiscent of natural stone, coverage with inclusions of a large fraction. In addition to high strength and decorativeness, polished concrete flooring is non-slip, easy to care for and durable. But not all concrete coating can be polished.

When is it necessary to mill the concrete floor?

Today you can often find concrete surfaces, poured without observing the technology and standards. Outwardly it can be manifested by unevenness, the presence of lapping, cracks. Visually invisible may be a difference in the strength of the concrete coating in one area.

What to do in such a case:

  • Completely renovate the coating. That is, pour over the existing one a new concrete coating with a thickness of at least 80 mm. Note that in some defects of the existing coating, this method is impractical.
  • Realize a high-strength self-leveling cement-polymer floor, with a thickness of 10. 20 mm. The new coating is applied on the repaired and leveled out the old one. It has a high decorative effect. Different decorations can be added to the mixture and even a logo can be reproduced on the flooring. This version can be successful in rooms where presentable appearance is very important: hotel lobbies, museum lounges, executive apartments, etc.п.
  • Remove a layer of concrete to a predetermined depth, i.e. to carry out milling. The milling can cope with slurry up to 2 cm in height.

Besides levelling, milling can also create anti-slip grooves, remove low-quality screeds (up to 1 cm), remove screeding and topcoat. Also milling will remove old dirt from the concrete surface, traces of lubricants and other hard-to-remove contaminants.

Milling machines

Depending on the equipment of the company executor or the parameters of the room where the milling will occur (availability of electricity), to mill both gasoline and electric machines (380V). Milling should be carried out to a depth of 2 to 7 mm in one pass. The depth is chosen based on the condition and properties of the existing concrete pavement. During milling, the layers are not peeled off to look as decorative as possible, but until the concrete reaches the strength properties, excluding the loss of aggregate. After using the disc milling machine, it is necessary to work with the mosaic milling machine, to remove the heights formed during milling. Sometimes the mowing-grinding process has to be repeated many times until the desired result is achieved.
