In any household, a minimal set of power tools is required, which helps to perform various tasks with less time and physical effort. One of these devices - sharpened electric.
Perhaps, in an ordinary apartment, it is not particularly necessary, since the knife can also be sharpened manually. But in a private or country house, this power tool is becoming more popular. In the country, it can be used for sharpening garden and household equipment.
Also, an emery machine is also necessary when repairing an apartment. On it you can sharpen drills for a drill, chisels for a perforator, a tool for removing old paint and plaster. Using abrasive stone, tiles, metal pipes, wooden plinths and so on are adjusted.
This power tool is safe to use because it has low engine speed. The household version of the sharpener is designed for 2 hours of continuous operation. The power of a household emery machine is from 120 to 400 watts. The greater the power of the electric motor, the more rigid the material that the grinder can handle.
Choosing an Electric Sharpener
If you use a tool that requires periodic sharpening, grinding or polishing, you need to purchase an electric sharpener. How to choose it depends on what type and amount of work you are going to use the device.
For sharpening a simple household tool, simple models with two circles of the same diameter but different thicknesses are quite suitable. Usually one of the circles has a thickness of 40 mm and a fine-grained structure, the second (20 mm thick) is intended for rough pre-treatment. To sharpen kitchen knives, an emery of 150 W and a stone diameter of 125 mm is enough. To sharpen shovels or axes, you need an abrasive wheel with a diameter of 175-200 mm and a machine with an engine power of 250-300 watts.
Pay attention to the diameter of the inner hole of the grinding wheel (fit). The most common is 32 mm. For landing 16 mm, 20 mm, 12.7 mm, it will be more difficult to choose the right circle. When choosing an emery, it is desirable to provide that the nozzles on the shaft allow the installation of discs with different inner diameters.
If you are going to process workpieces for a tool, an electric sharpener with an additional brush disk will suit you. It serves for preliminary cleaning of material that has not previously been sharpened. On some models, the second wheel is replaced by sanding belt. For sharpening drills you need a machine with special grooves. But such grooves are usually not provided on the tool for processing large and thick products, such as axes or shovels.
For finer surface treatment of objects, there are models with different speeds of rotation of the circles. They are usually located in sharpeners perpendicularly. But such machines have large dimensions and they need a large area. The power tool market is saturated with a variety of models of similar devices from various manufacturers. Of domestic brands, the Zubr and Kraton machines have a good reputation.
Knife sharpener
There are household appliances designed specifically for sharpening kitchen knives or scissors. Sharpened electric is now used not only by cooks of restaurants and cafes, but also ordinary housewives. To get a sharp blade, no special skills are required. During sharpening, there is no need to perform complex manipulations with the knife.
The electric knife sharpener itself determines the correct sharpening angle. The process takes place in two or three stages, followed by verification of the result. First, sharpening is carried out directly with abrasives, then polishing the surface of the blade on ceramic plates. Models are often equipped with diamond coated element blocks. Therefore, they work for a long time without the need to replace parts.
