Grinding wheel diamond: an overview, description, types and reviews. Diamond grinding wheel

Grinding machines are provided with special nozzles that directly perform the function of adjusting the cutting elements. The equipment is supplied with grinders, which are traditional circular or bowl-shaped disks. Most of these attachments are abrasives made of volcanic substances and other stony mixtures. But a special place in this family is occupied by a diamond circle for grinding tools, which has a fine-grained functional surface. It is not possible to perform the processing of a coarse blade on such a tooling, but there is no equal in the maintenance of carbide materials, napayk on drills and circular saws.

General information about grinding discs

Features of diamond grinding elements are determined by the nature of their purpose. Masters use this abrasive to work with the cutting components of another tool. With chainsaws, cutting metal heads and steel tools, only high-strength rigging will handle. Moreover, for safety reasons, technologists also provide a safety margin for consumables. And grinding wheel diamond meets high requirements, providing not only strength, but also resistance to wear. By the way, some models of such elements are used even in the processing of granite, which confirms the high productivity of the material.

Even if you do not plan to work with solid-state billets, the discs are used for reasons of economy, due to a high working resource. True, alternative applications do not always justify themselves, because the diamond circle for grinding tools has a small grain. Theoretically maintenance of axes, knives and other devices with relatively modest hardness values of the blade is possible, but the workflow will take much longer.

Varieties

The main classification involves the separation of diamond elements in shape. As already mentioned, the most common are cup-shaped and flat disk grinders, which are used especially for solid-state cutting and saw parts. There is also a borderline variety represented by circles in the form of a plate. It can be said that this is a universal diamond circle, which is suitable for a wide range of grinding operations. If you plan targeted treatment with certain parameters, then you should choose the abrasive not only in form, but also in terms of technical characteristics.

Main characteristics

There are two main parameters on which the grinding wheels are chosen by experienced masters - this is the degree of granularity and size. The designations used to designate these indicators use digital designations. As for the dimensional parameters, they are represented by the width, thickness and fit, that is, the diameter of the hole inside the disc. For example, the standard width is 150 mm, the thickness is 10 mm, and the fit is 30 mm. The granularity that a diamond circle possesses is represented by a double digit - for example, 125/100 μm. The higher this value, the rougher the grinding will be performed. For a conventional tool in the form of knives and other blades of household devices, a coarse grain size is also sufficient, but for fine work with hard, high-strength alloys, a fine fraction with a dense structure is necessary.

Edit diamond circles

Over time, diamond abrasives lose their former shape, which affects the quality of the grinding. In such cases, it is necessary to perform editing using one of the methods recommended by specialists. Thus, by means of machining on a grinding machine, the disc can be provided with stepping and rounding. Often used and special devices in the form of abrasive bars and consumables with a similar effect on the structure. In particular, it is recommended to correct the circle with a diamond pencil with the appropriate characteristics. Typically, this operation is used when diamond surfaces appear on the surface of the disc. Alternative methods of dressing include electrochemical methods and the application of a lubricant containing micropowder with abrasive impregnations.

Reviews about disks "Caliber"

The domestic manufacturer of tools and components produces diamond consumables for various purposes. Users note that at a low price such products provide high-quality and accurate processing. In the composition of circles, raw materials with optimal properties are used, which makes it possible to perform accurate sharpening with minimal time costs. However, in terms of longevity, the diamond circle for the "Caliber" grinding is far from being the best option. Still, low cost affects, because of which the properties of material reliability were also lowered. However, if the grindstone is selected for one-time, but responsible tasks, then this option is quite suitable. Also it can be preferred if you serve a household tool that does not require special loads when sharpening.

Reviews about disks Jet

The products of the American brand Jet are praised by ordinary users and specialists. The merits of products include universality and optimal sharpening performance. In the brand line, you can find a complete set for performing any abrasive operations, even with a professional cutting tool. In addition, the grinding wheel diamond is able to perform and function as the correct element for other abrasives. Among the shortcomings, users note the high price tag and the need to carefully select the disks by size, since the markings are inconsistent with the actual indicators.

User Reviews for Oregon

The company primarily focuses on the professional needs of consumers, that is why in its families it represents elements for grinding machines of high class and with corresponding performance. Customer feedback notes that the Oregon diamond circle is also distinguished by its reliability. Some owners regularly operate such abrasives for several years. Of course, in the process of use, editing is also applied, but even with maintenance in mind, this is a good result.

Conclusion

Diamond equipment for the assembly of grinding machines is one of the most effective ways to maintain the cutting ability of solid-state heads. This method of abrasive processing allows you to service crowns for perforators, winning cutters and even restore the performance of chain chainsaws. Achieved high result of sharpening due to the fact that the diamond wheel has increased strength and durability properties. But this does not mean that any element of this type can be used as a universal element. Diamond discs also differ in abrasive characteristics, shape, structure of the internal composition and surface treatment. In view of these parameters, you should select the abrasive for specific tasks. For example, for a knife or a plane, the best option would be a circle with a large grain size, and for delicate work with the winning nozzles it is worth using fine-fragmented elements.
