Every home builder has a grinding wheel, Every home builder has a grinding wheel. Naturally, Every home builder has a grinding wheel, Every home builder has a grinding wheel. Every home builder has a grinding wheel, Every home builder has a grinding wheel.
Every home builder has a grinding wheel, Every home builder has a grinding wheel. According to GOST, Every home builder has a grinding wheel. With their help processing of various surfaces is carried out. If we talk in detail about these products, then they are a body with a certain degree of porosity. They contain abrasive materials, and in addition artificial natural elements, acting as binders.
It is quite appropriate to compare the abrasive wheel with the teeth of an ordinary saw. After all, essentially, they perform the same task. The main difference, consisting between them, is, that on a grinding wheel they are scattered on its perimeter, and on the saw they are located mainly on the edges of the tool.
A large number of solid particles, contained in the grinding wheel, provides high-quality cleaning of the surface from foreign components. Using this tool, you can quickly process the workpiece. According to GOST, grinding wheels are excellent for processing products from:
Applying grinding wheels in accordance with the requirements of GOST, you can perform easy cutting of bricks, as well as roofing slate. In addition, they can be used for cutting ceramics and concrete. They are suitable for surface treatment of various materials. Applying them, you can easily make grooves and deepen the required depth and shape.
If you refer to the current GOST , then it is recorded, that all grinding products are divided into such types:
An ordinary man, which is often used to perform the operation before the use of grinding wheels, easier to understand the classification, in which all varieties of these tools are divided by purpose and application. Such grinding wheels are most often used in domestic conditions:
Self-locking on Velcro. The main feature of these tools is their reliable self-engagement with the support of the grinder. This is ensured by the presence of a special fabric on the sanding paper.
Petals. A characteristic feature of this tool of the species is its excellent adaptability to the surface, polished. in addition, such circles are highly elastic. They have a fan orientation. This is why they have such an unusual name. One of the advantages of this tool is the absence of secondary burrs. They are most often used for processing pipes.
Grinding wheels on metal. They are indispensable in cases, when it is necessary to process welds and remove burrs. In the manufacture of these products, manufacturers pay special attention to testing this tool for mechanical strength.
Fiber. Their main feature is the presence of a support plate of a certain cross section, thanks to which they are fixed on the grinder. Multilayer vulcanized paper is used to make these GOST circles. These products can be used to clean stainless steel products, wood.
Diamond. Experts recommend using them for finishing the surface. With, using them, you need to keep that in mind, that diamond has low strength and is characterized by high fragility.
Bring together all the parameters, on the basis of which grinding wheels are divided, almost unreal. According to GOST, these products differ in brand depending on the following characteristics:
When choosing a particular brand of grinding wheel must take into account the characteristics, which were listed above.
According to GOST, all parameters, which were previously considered, usually indicated in the complete labeling of abrasive tools.
The manufacturer of this tool often produces product labels in their own way. The most common labeling option will be listed below. It is more understandable to consumers. The buyer can easily decrypt the product information. If you find a grinding wheel in the store, satisfies GOST, with marking 25A25SM26KB3, then it must be understood in this way:
In the same way it is possible to carry out decoding of marking of other grinding wheels. However, some parameters may be missing. Example, as evidenced by GOST, individual circles in the marking may not contain an accuracy class. And in other grinding wheels there are new parameters. Example, the label may contain the following characteristics, as the circumferential speed.
Speaking of the characteristics of this tool, it is necessary to tell separately about granularity, which is also reflected in GOST . This characteristic is very important, because it depends on the purity of the surface, which is obtained after processing. exept this, it determines a number of other parameters:
When choosing the grain size of the product must take into account the allowance, which master plans to remove when using it for grinding. The roughness of the product surface should also be taken into account, treatable. The smaller the grain size of the grinding wheel, the cleaner the surface. You should know, that the fine grain size of the grinding wheel is often the cause of salting of the product and burning of the material, subjected to the grinding procedure. In addition, the productivity of grinding wheels markedly decreases with decreasing grain size.
During the operation of the grinding wheel in the geometry of the product may occur violations. It has to do with that, that in the process of using abrasive grains will break out of the bond under the influence of smoothing, abrasion and destruction. To restore high cutting ability for the product and restore its geometric shape, it is necessary to perform the procedure of editing the circle. It is the removal of abrasive bonds from the surface of the product using a special tool.
Editing can be done in different ways. During the procedure can be used as a diamond, and a diamond-free tool. According to GOST, in the conditions of industrial enterprises it is made by free abrasive or with use of technology of rolling. If the master decided to edit the pressed circle at home, then in this case you can resort to the use of more sophisticated devices for editing the circle. You can use it to repurpose, to clean the circle from salting.
Speaking of grinding wheels, it is necessary to tell about additional equipment, which is used in the process of using grinders. In addition to paired plates, such equipment includes the following elements:
Note, that the category of additional equipment includes industrial vacuum cleaners. Thanks to them processing of a stone and concrete thus formation of a dust on a platform is provided. To avoid such a problem, as a jam, it is necessary to use special quick-release nuts.
According to GOST, use of consumables for their intended purpose, as well as the use of additional cleaning of the product will help to perform the planned work in a short time. At the same time, your tool will be used as efficiently as possible during working hours.
Remember, that the operation of consumables, which are damaged, have non-standard dimensions or have been stored incorrectly, is unacceptable.
It is important to use the tool for its intended purpose, and with it the additional elements. Some people unknowingly use grinders to saw firewood. They cannot be used for this purpose. They are not designed for that.
It is also necessary to properly store abrasive materials and not use them, in which the expiration date has already expired. Defective materials should also not be used.
Grinding wheels are the most common tool, which is not only specialists in enterprises, but also at any house master. They are used mainly for the operation of forging blanks and products from a variety of materials. To qualitatively process a detail using this tool, it is necessary to choose the right grinding wheel, given the characteristics, reflected in Guests . The color should be taken into account when choosing, purpose and a number of other parameters. By selecting a product based on these criteria, you can ensure the speed and ease of the grinding operation and save time on this operation.
Only suitable grinding wheels should be used when grinding . At the same time it is necessary to refuse application of products, which have defects or damage. This will not help to achieve the desired result when performing the operation of processing the part.
