Grinding and boring machines are equipped with special nozzles that directly perform the function of adjusting cutting elements. The equipment is supplied with sharpeners, which are traditional circular or bowl-shaped discs. Most of these nozzles are abrasives made from volcanic substances and other stony mixtures. But a special place in this family is occupied by a diamond wheel for sharpening tools, which is distinguished by a fine-grained functional surface. It will not work to process a rough blade on such a tool, but on the other hand, in the maintenance of carbide materials, soldering on drills and circular saws, a diamond blade has no equal.
General information about sharpening discs
Features of diamond sharpening elements are determined by the nature of their purpose. Craftsmen use this abrasive when working with the cutting components of another tool. With chain saws, metal cutting heads and steel cutters, only high-strength equipment can handle it. Moreover, for safety reasons, technologists also provide for a margin of safety for consumables. And sharpeningthe diamond wheel 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 blanks, disks are used for reasons of economy due to a high working resource. True, alternative use does not always justify itself, since the diamond wheel for sharpening tools has a small grain. Theoretically, maintenance of axes, knives and other devices with relatively modest blade hardness is possible, but the workflow will require much more time.
Varieties
The main classification provides for the division of diamond elements by shape. As already mentioned, the most common are bowl-shaped and flat disc sharpeners, which are used specifically for solid cutting and saw parts. There is also a border variety, represented by circles in the form of a plate. It can be said that this is a universal diamond wheel that is suitable for a wide range of sharpening operations. If purposeful processing with certain parameters is planned, then you should choose an abrasive not only in shape, but also in terms of technical characteristics.
Key Features
There are two main parameters by which experienced craftsmen choose grinding wheels - this is the degree of grit and standard size. In labeling, these indicators are useddigital designations. As for the dimensional parameters, they are represented by the width, thickness and fit, that is, the diameter of the hole inside the disk. For example, the standard width is 150 mm, the thickness is 10 mm, and the fit is 30 mm. The graininess that a diamond wheel has is represented by a double digit - for example, 125/100 microns. The higher this value, the coarser the sharpening will be. For ordinary tools in the form of knives and other blades of household appliances, coarse grit is enough, but for accurate work with hard high-strength alloys, a fine fraction with a dense structure is needed.
Editing diamond wheels
Over time, even diamond abrasives lose their former shape, which affects the quality of sharpening. In such cases, it is necessary to carry out editing by one of the methods recommended by experts. So, with the help of processing on a grinding machine, the disk can be provided with stepping and rounding. Often, special devices are used in the form of abrasive bars and consumables with a similar principle of influencing the structure. In particular, dressing the wheel with a diamond pencil with suitable characteristics is recommended. Typically, such an operation is used when diamond grains appear on the surface of the disk. Alternative dressing methods include electrochemical methods and the application of a lubricant, which contains micropowder with abrasive inclusions.
Reviews about discs "Caliber"
A 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. As part of the circles, raw materials with optimal properties are used, which allows you to perform accurate sharpening with minimal time costs. However, in terms of durability, a diamond wheel for sharpening the Caliber brand is far from the best option. Still, the low cost affects, due to which the reliability properties of the material were also reduced. However, if the sharpener is selected for one-time, but responsible tasks, then this option is quite suitable. It can also be preferred if servicing a household tool that does not require special loads when sharpening.
Reviews about Jet wheels
Products of the American Jet brand are praised by both ordinary users and specialists. The advantages of products include versatility and optimal sharpening performance. In the brand line, you can find a complete set for performing any abrasive operations, even for professional cutting tools. In addition, the diamond grinding wheel is able to perform the function of the correct element for other abrasives. Among the shortcomings, users note the high price tag and the need for careful selection of disks by size, as there are discrepancies in the labeling with actual indicators.
Oregon wheel reviews
The company primarily focuses on the professional needs of consumers,therefore, in its families it represents elements for grinding machines of high class and with corresponding performance. User reviews note that the Oregon brand diamond wheel is also reliable. Some owners regularly operate such abrasives for several years. Of course, in the process of use, editing is also applied, but even with maintenance, this is not a bad result.
Conclusion
Diamond tooling for 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 drill bits, victorious cutters, and even restore the performance of a chainsaw. A high sharpening result is achieved due to the fact that the diamond wheel has increased properties of strength and wear resistance. But this does not mean that any element of this type can be used as a generic element. Diamond blades also vary in terms of abrasive characteristics, shape, internal composition and surface finish. With these parameters in mind, an abrasive should be selected for specific tasks. For example, for a knife or a planer, the best option would be a wheel with a coarse grit, and for delicate work with victorious nozzles, you should use fine-grained elements.
