Grinding and boring machines are equipped with special nozzles that directly carry out the function of adjusting the cutting elements. The equipment is equipped with sharpeners, which are traditional circular or bowl-shaped discs. Most of these nozzles are abrasives made of volcanic substances and other rocky mixtures. But a special place in this family is occupied by a diamond wheel for sharpening tools, which differs in a fine-grained functional surface. It will not be possible to process a rough blade on such a tool, but there is no equal to a diamond blade in the maintenance of carbide materials, solders on drills and circular saws.
General information about grinding wheels
Features of diamond grinding elements due to the nature of their purpose. Masters use this abrasive to work with the cutting components of another tool. With chain saws, cutting metal heads and steel cutters, only high-strength equipment can handle it. Moreover, for safety reasons, technologists also provide a margin of safety for consumables. And the diamond grinding wheel meets high requirements, providing not only strength, but also wear resistance. By the way, some models of such elements are even used in the processing of granite, which confirms the high productivity of the material.
Even if it is not planned to work with solid-state workpieces, disks are used for reasons of economy due to the high working resource. True, the alternative application does not always justify itself, since the diamond wheel for sharpening tools has a small grain. Theoretically, servicing axes, knives and other devices with relatively modest indicators of blade hardness is possible, but the work process will require much more time.
Varieties
The main classification involves the separation of diamond elements in shape. As already mentioned, the most widespread are cup-shaped and flat disc sharpeners, which are used specifically for solid-state cutting and sawing 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, which is suitable for a wide range of grinding operations. If you plan targeted processing with certain parameters, then you should choose an abrasive not only in form but also in technical characteristics.
Main characteristics
There are two main parameters by which experienced craftsmen choose grinding wheels - this is the degree of granularity and size. The markings use numerical designations to indicate these indicators. 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 granularity possessed by the diamond wheel is represented by a double digit - for example, 125/100 microns. The higher this value, the rougher the sharpening will be performed. For a conventional tool in the form of knives and other blades of household appliances, coarse grain is sufficient, but a fine fraction with a dense structure is required for accurate work with hard high-strength alloys.
Editing diamond wheels
Over time, diamond abrasives lose their former shape, which affects the quality of sharpening. In such cases, it is necessary to carry out the editing with one of the methods recommended by specialists. So, by processing on a grinding machine, the disk can be stepped and round. Often used and special devices in the form of abrasive bars and consumables with a similar principle of influence on the structure. In particular, it is recommended that the circle be edited with a diamond pencil with suitable characteristics. Typically, this operation is used when diamond grains appear on the surface of the disk. As alternative methods of dressing, we can name electrochemical methods and applying lubricant, which contains micropowder with abrasive inclusions.
Reviews on the disks "Caliber"
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 accurate grinding with minimal time costs. However, in terms of durability, a diamond wheel for sharpening the Caliber brand is far from the best option. All the same, low cost affects, because of which the properties of material reliability have been reduced. However, if the grinder is selected for one-time, but responsible tasks, then this option is quite suitable. It can also be preferred if you are servicing a household tool that does not require special loads when sharpening.
Jet Wheel Reviews
The products of the American Jet brand are praised by both ordinary users and specialists. The advantages of the products include versatility and optimal sharpening performance. In the brand line you can find a complete set to carry out any abrasive operations in relation to even a professional cutting tool. In addition, the diamond grinding wheel is able to perform the function of the right element for other abrasives. Among the shortcomings, users note a high price tag and the need for careful selection of disks according to size, since discrepancies in the marking are found with actual indicators.
Oregon Wheel Reviews
The company primarily focuses on the professional needs of consumers, therefore, in its families, it represents elements for high-class grinding machines with the corresponding productivity. User reviews note that the Oregon diamond wheel is also reliable. Some owners regularly operate such abrasives for several years. Of course, editing is also applied in the process of use, but even taking into account maintenance, this is a good result.
Conclusion
Diamond tooling for completing grinding machines is one of the most effective ways to maintain the cutting capabilities of solid-state heads. This method of abrasive processing allows you to maintain crowns for perforators, winning bits and even restore the performance of a chainsaw. A high sharpening result is achieved due to the fact that the diamond wheel has improved strength and wear resistance properties. But this does not mean that any element of this type can be used as universal. Diamond blades also vary in abrasion, shape, structure, and surface finish. Given these parameters, you should choose an abrasive for specific tasks. For example, for a knife or a planer, a circle with a large grain size will be the best option, and for delicate work with victorious nozzles it is worth using fine-grained elements.
