The abrasive grinding machine is characterized by:
Due to intense friction, leaving a high grinding zone temperature. This can cause stress and deformation of the workpiece, and even cause surface burns. It is necessary to inject a lot of grinding coolant to reduce the grinding temperature. Coolant also played Chip and lubrication.
Grinding large radial force. This causes the machine - Flexible concessions workpiece system, so that the actual depth of cut is less than nominal depth of cut - wheel. Therefore grinding will be complete, we should not feed light grinding to eliminate errors.
Abrasive blunt, the grinding force also increased, resulting in grains or broken off, again exposing the sharp edge, this feature is called "self-sharpening." Self-sharpening, the grinding can be normal within a certain time conduct, but work more than a certain time, give artificial trimmed, so the grinding force increases caused by vibration, noise and damage the workpiece surface quality.
Since the metal cutting wheels itself has high hardness and heat resistance, and therefore the grinding can be processed high hardness materials such as hardened steel, carbide.

A wide range of wheel:
Press the abrasive can be divided into ordinary abrasive (corundum and silicon carbide, etc.) and natural abrasive grinding wheels and superabrasive (diamond and cubic boron nitride) grinding wheel;
According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, tile granite cutting wheels, disc wheel and so on; by binding agent can be divided into pottery wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters metal cut off wheels, viscosity, hardness, binding agents, shape, size and the like.
Since the wheel typically operate at high speed, before turning test should be carried out so that the use of (guaranteed at the maximum operating speed of the wheel, do not break) and static balance test (when working to prevent vibrations caused by the machine). Grindstone at work for some time, it should be trimmed in order to restore the grinding performance and correct geometry.

Wheel of life
In the grinding process, with the wheel itself wear, wheel face state is changing. The longer the time, the lower the cutting ability of the grinding wheel, a variety of grinding defects will continue to emerge, the grinding not up to standard. Then it must trim grinding wheels to reach normal state. We usually refer to is the actual grinding wheel life time in two trim wheel between. Wheel length of life directly affects the grinding effects, especially more important for profile grinding.

Install the wheel on the grinder should?
Wheel is working at high speed, then fly or easily spill caused no casualties. So be especially careful before using checks, does not allow cracks. The installation must be reliable, and to go through static balance adjustment, so it will not cause injury.
Between the wheel and the wheel shaft or bore cylindrical flange, not too tight, otherwise the grinding thermal expansion, easy to wheel bursting, not too loose, otherwise prone to eccentric wheel, loss of balance, so as to cause vibration. Usually with the gap of 0.1 ~ 0.8mm, high speed grinding wheel gap to be smaller. When the wheel clamping flange with two flange diameter should be equal to the outer diameter shall be not less than 1/3 of the wheel diameter. Application of the end surface between the flange and the wheel cardboard or oil and rubber, and so do the pad, the pressure evenly distributed, the tightening force of the nut can not be too large, otherwise the wheel will break. Note the tightening screw rotation, and the wheel should spin in the opposite, that is, when the wheel is rotated counterclockwise, with right-hand thread, so that the diamond reinforced concrete in force, will drive the screw nut more tightly.

The introduction and use of the characteristics of the wheel
Wheel is binding agent with many small flange or corners mineral crystal particles cemented together to form. Wheel hardness than particles is grinding and cutting tools, but also the need to have sufficient strength and flexibility, we can resist the impact force generated by the grinding process. These particles are obtained after crushing abrasive.
The abrasive is made from natural and man-made abrasive abrasive material commonly used natural abrasive corundum, emery. Artificial Abrasive ordinary alumina, white alumina, black silicon carbide, green silicon carbide. The size of the abrasive particles called concrete cutting wheels size.
Grindstone at work due to the surface of the particles and the friction between the cutting tool, it will gradually wear blunt, when the grinding resistance beyond the adhesion between particles and a binder, the particles began to fall off, and was replaced by new sharp particles. So the wheel has a self-sharpening performance. But adhesion binding agent should not be too strong, too strong as particles after blunting also attached to the wheel surface grinding wheel will lose effect. Further, since the granite cutting disc and the workpiece is friction will have a lot of heat, the binding agent can easily be softened. By grinding the metal material at the end of the adhesive binder filled with sand in the cracks between the wheel stopper reality. If this plug solid wheel continues to work, not only relatively low efficiency, are causing annealing grinding and cutting tools also become blue. On the other hand if the binding agent is not firmly bonded particles in the particle has not been changed between the pure grinding but also will make it fall off, so wear faster transmission lines sand, easily deformed, require regular trimming.

What is self-grind of the wheel
Since grind of the wheel are also known as "self-sharpening."
Grinding wheel action depends mainly on grains exposed sharp edges, during grinding, sharp edges will gradually be worn and blunted, weakened capacity stainless steel cutting wheels.
Then peel off the surface of the grains or broken, thereby forming a new blade grinding, grinding in order to achieve the effect of a sharp, which is self-sharpening.
Sparks generated during grinding is grinding down a portion of another part of the metal debris is broken off or sand.
If the spark is short, it is bound to self-sharpening poor, a reduced ability to grinding, small metal shavings mill under a sand can not afford to, so little spark and short.

Pottery wheel performance
Ceramic grinding wheel is a cutting tool, which consists of many small and hard, abrasive and adhesive binders from the porous body. Abrasive cutting directly responsible for the work, sharp and must have a high hardness, heat resistance and a certain toughness. Commonly used abrasive alumina (also known as corundum) and silicon carbide two kinds. Alumina-based abrasive, high hardness, good toughness, suitable for grinding steel material. Type silicon carbide abrasive hardness higher, sharper, good thermal conductivity, but more brittle, suitable for grinding cast iron and tungsten carbide.
For the same abrasive grinding wheel, because of its different thickness, surface roughness and processing efficiency is not the same after the workpiece, coarse grains for rough grinding, fine abrasive grains, the more rough abrasive grain size number smaller.
Binding agents from bonded abrasive effect. Commonly used ceramic binders, followed by the resin binder. Different binders choice of materials, the impact wheel corrosion resistance, strength, heat resistance and toughness.
The more firmly bonded abrasive particles, the more difficult to fall from the wheel, the hardness of the wheel is said that the hardness of the wheel is the degree of difficulty of the stainless steel cutting wheel surface under loads off. Easy to fall off called soft, otherwise known as hard. The abrasive grinding wheel hardness and hardness are two different concepts. Surface grinding of the workpiece is relatively soft, abrasive cutting edge (corner) on easy to wear, this time may be longer use abrasive, that some of the firm bonding optional wheels (high hardness of the wheel). Conversely, a low hardness grinding wheel for high hardness workpiece.
Ceramic wheel at high speed work, in order to ensure safety, should be checked before installation, there should be no cracks and other defects; in order to make the wheel steady, balancing test should be carried out before use.
concrete cutting blade after working a certain time, the surface voids are clogged debris, abrasive acute angle blunt, the original geometry will be distorted. It must be trimmed in order to restore the cutting ability and the correct geometry. Required diamond grinding wheel dressing pen.

How to Install Ceramic wheel
Due to the high speed of pottery wheel, grinding wheel and more brittle, damaged and may occasionally result in serious consequences, therefore, whether the wheel is installed properly reasonable, safe and reliable, it is very important. Wheel of installation must be carried out carefully to ensure production safety grinding.
Ceramic wheel installation should pay attention to the following safety technology issues.
① aperture wheel should be freely attached to the concrete cutting wheels spindle or wheel chucks, and remain in compliance with the clearance aperture crude refining on the technical requirements.
Wheel pore size is too large, allowing the use of the liner shrinkage. Bush width smaller than the width of the wheel, but not less than 1/2 the thickness. Wheel chuck diameter of not less than 1/3 the diameter of the wheel, the wheel in order to ensure there is enough power and torque.
Wheel chuck have sufficient rigidity, after pressing the sides to maintain contact with the wheel flat and uniform, must be pressed between the pad surface with a flexible gasket (asbestos rubber sheet) and a thickness of 1 ~ 2mm, a diameter greater than card disc diameter 2mm appropriate. To ensure that the contact surface between energy compaction, compaction, should be kept clean and free of attachments.
When ② installation woodworking saw blade, should pay attention to controlling the compression nut or screw tightness, it is necessary to ensure when the grinding wheel does not slip, but also to prevent excessive pressure, resulting in wheel damage, therefore, it is best to use a torque wrench. If multiple time compression screw shall diagonal order, gradually tightening; wheel and chuck the total weight exceeds 16kg, it should be mounted on a grinder lifting methods and collision avoidance; install the new wheel to check to make sure safe only after the test, all the normal sounds and operation, etc., that can be put into production.

How to choose the wheel?
Abrasive wheel is a grinding tool indispensable, select the appropriate wheel or not, affect the quality of grinding, the grinding cost important condition. The company produces a range of surface grinders, the wheel must be configured to accommodate different plane processing various workpiece. For the convenience of the user and the company design, technology choices, which this paper plane grinding, grinding wheel used different workpiece material selection summary for everyone to use reference.
Many different types of stainless steel cutting wheel, and a variety of shapes and sizes, due to the different abrasive grinding wheel, grinding wheels binder material and manufacturing process, the wheel would have a variety of different performance. Each tile cutting wheel in accordance with its own characteristics, there is a certain scope. Therefore, grinding, must be based on the specific circumstances (such as the material properties of the workpiece grinding, heat treatment method, the workpiece shape, size and processing forms and technical requirements, etc.), choose the appropriate wheel. Otherwise it will directly affect the inappropriate choice of wheel machining accuracy, surface roughness and productivity.

Cut off wheels
LEMAN concrete cutting wheels is usually cut with water (wet cutting), for concrete cutting wheels with adequate water can significantly reduce the dust, keep construction cutting blades cool and extend its life, and improve the cutting efficiency (for wet cutting can be deep and continuous).
However, when there is no water source near the work area, you have to perform dry cutting. As said in the previous section, dry stainless steel cutting wheel should be intermittent and shallow. If deep cutting depth is needed, you should do several passes of shallow cuttings.

Concrete cutting disc
Often the decision of stainless steel cutting wheels wet or dry depends on your preference and job requirements. Dry cutting eliminates messy wet slurry and the need to equip saws with water tanks and hoses. Using a blade wet, on the other hand, reduces dust but makes it necessary to contain or clean up the slurry. For indoor jobs where you need to keep the work area dry, a dry-cutting blade and compatible saw may be your only option.
The main difference between wet and Tile cutting discs is the weld (as described in Step 1). Dry-cutting blades have segment welds that resist heat and don't require water for cooling. They are usually intended for intermittent cutting and for use on handheld, low-horsepower saws. If you're sawing decorative pattern lines in concrete, dry-cutting blades are often the best choice for making crisp, clean cuts (see Sawing and Patterning). These decorative cuts are typically only 1/16 to 1/4 inch deep and do not function as control joints.
Wet-cutting blades are typically used with walk-behind saws for cutting joints in cured concrete flatwork because water cooling permits deeper cuts. Although it's possible to use most abrasive factory with water, never use a wet-cutting blade dry. Always continuously cool the blade with water to avoid segment loss and blade warpage.

Construction cutting blades
For maximum cutting speed and blade life, you should match the blade as closely as possible to the material you're cutting. Characteristics of the concrete you need to know include the compressive strength, the size and hardness of the aggregate, and the type of sand.
Blade manufacturers consider concrete with a compressive strength of 3000 psi or lower a soft material and Diamond cutting discs with a strength above 6000 psi a hard material. Therefore, you should use a blade with a hard bond to cut the lower-strength concrete and a blade with a soft bond to cut high-psi concrete. Similarly, hard aggregate (such as trap rock, basalt, and quartz) dulls diamond particles quickly, so use a blade with a softer bond to allow new diamonds to be exposed as needed.
The size of the aggregate in concrete primarily affects blade performance. When cutting through larger aggregate (3/4 inch and up), construction cutting discs and wears more slowly. Pea gravel (smaller than 3/8 inch) is easier to cut, but the blade will wear faster.
The type of sand determines the abrasiveness of concrete, with sharp sand being the most abrasive cutting wheel and round sand the least. To determine the sharpness of the sand, you need to know where it's from. Crushed or river bank sand is usually sharp while river sand is round and nonabrasive. The more abrasive the sand, the harder the bond requirement.
What if you will be cutting more than one type of concrete? As a general rule, manufacturers recommend choosing the blade based on the material you'll be working with most often or the material for which top blade performance is most important. Most diamond blades can cut a range of materials.

Concrete cutting discs
Concrete can also be cut with abrasive blades, but diamond blades are recommended, for cutting blades can provide at least two times faster cutting, less downtime, and constant depth of cuts.
If you use the diamond blades occasionally and your jobs are small, you can choose the economical grade diamond construction to save your expense (but the cutting speed of the economical diamond blades should be fast enough). If you use the diamond blades frequently or the job is big, you should choose high grade professional diamond blades, for this can decrease your cost per cut.
If you are not sure that you can do concrete cutting wheels job well, you can just hire a professional concrete cutting company to do the job for you.

Diamond discs
You should at least wear a professional respirator, not only in dry cutting, but also in wet cutting, because the small dust particles generated in metal cut off wheels process can penetrate deep into the lungs and can cause serious health effects such as lung cancer or silicosis. If the job is big, other equipment like goggle, earplugs, and protective clothing should also be adopted.
To make the cut straight, you can use a chalk line to mark a straight line on diamond blade, and then place a straight wood board along the line. Then you can cut a shallow line on the concrete along the wood board. The cut can be about 1/4″ deep.Having this shallow straight metal cutting discs, you can perform further cuttings along it to gain the cut you need.

Til granite cutting wheels
What type of handheld saw or flat saw are you using? What is the horsepower and operating speed (or rpm)? Blade manufacturers provide charts with recommended operating speeds and maximum safe operating speeds for their blades. You'll also find this information stamped right on the multi use diamond disc.
Always match the blade with the speed range of the saw. Operating the blade at a lower speed than recommended can concrete cutting blades its cutting life and performance. Exceeding the blade's maximum rpm rating can damage the blade and risk injury to the saw operator.
Other factors to consider:
Blades designed for wet use only must be operated by saws that can deliver a continuous supply of water to cool the blade.Most blades for cutting green concrete are designed for use with special early-entry saws that minimize joint raveling and spalling.Don't use a blade that exceeds the maximum blade diameter and tile cutting wheels depth capacity of the saw.

Concrete cutting discs
Concrete cutting process with the acceleration of urbanization, rapid urban construction.In the big city, the ground has been unable to meet the transport needs of urban traffic up to the elevated light rail, extending down to the subway.Some elevated now seems to have become the factors that restrict the development of cities. reinforced concrete cutting wheels Alterations to these elevated part, inevitably removed, also ensuring that the part is not affected and can be reused, that before us has become a problem.At the time that there was nothing traditional demolition, advanced reinforced concrete cutting by a safe, efficient and environmentally-friendly features.
concrete cutting blades and cutting technology of reinforced concrete diamond wire cutting method.Diamond wire cutting method is faster, more flexible and lower noise.Especially in the construction and renovation project in the growing number of applications.Disc cutting method cutting after breaking away from the traditional pneumatic chipping or blasting construction methods, adopted with a diamond cutting discs cutting, construction cutting neat, straight, does not require subsequent processing, not affected by construction sites, environmental protection, construction, security conditions, are widely used in all kinds of cutting structural transformation and the construction of large buildings.Steel wire-cutting equipment by location of high-power hydraulic machines, drive pulleys and steel line combined with a diamond saw, and hydraulic motor driven through the transmission pulley rotates around the object to be cut high speed steel wire cutting, high operation speed, low noise and no vibration, no dust pollution advantages,metal cutting wheels and cut straight and smooth, without doing the rehabilitation process.By using this technology, for some construction projects with special requirements, such as pressing time limit, high environmental requirements, as well as some large demolition of concrete structures, cutting engineering, these problems can be solved.
