With prolonged use of abrasive grinding wheels, their surface is often clogged. For example, after processing gardening tools, it is already quite problematic to sharpen a drill bit for metal.
To edit grinding wheels on an emery machine, the author suggests using a roller cutter, which you can make yourself.
Of the basic materials, special asterisks in the amount of 10 pieces (for the standard width of the abrasive wheel) and a piece of a rectangular profile pipe with a cross section of 60 * 30 mm will be required.
Moreover, note that the washers come with sharp and blunt teeth. With the help of the first, dressing of fine-grained grinding wheels is carried out. Whereas blunt washers are used mainly for dressing circles of medium and large grain size.
The main stages of work
First of all, it is necessary to cut a piece of a profile pipe of a suitable size and drill a hole in the center for a bolt with a diameter of 14 mm.
At the next stage, you need to cut a piece of the profile pipe and weld a piece of round tube (this will be a homemade handle). The result is a fork.
After that, stars are inserted between the walls of the profile and fixed with a bolt. It is not necessary to tighten strongly, they must rotate freely.
