Cycling ( scrapping ) - the technology of leveling wooden (less often plastic) surfaces by scraping. Performed by manual cycles or mechanized equipment.
Cycling should not be confused with abrasive grinding and planing .
Technology
The purpose of the looping is to remove minor irregularities and a wooden “pile” after the cutting tool. The looping is performed by scraping thin chips from the surface. A layer of material with a thickness of hundredths or tenths of a millimeter is removed. So that the process is just scraping, and not cutting (as with planing), the cycle has a special sharpening. The cycle is a steel or glass plate with a sharpening of about 90 degrees (almost a cut or chip). Quality cycles have a burr on the work surface, which scrapes the material.
Before work, it is recommended to moisten the tree to facilitate the process. The cycle is always led along the fibers, slightly tilting towards the front.
Depending on the initial state and final requirements, the cycling can be an intermediate operation between rough processing (cutting, planing, milling) and finishing ( polishing ).
Cycle not only flat, but also surfaces of complex shape using a curly cycle.
Application
Cycling is a common manual carpentry operation. In industry, it is practically not used due to the low productivity and complexity of sharpening the cycle. Instead, planing and grinding are used.
The best known in everyday life is the cycling of wooden ( parquet ) floors. However, strictly speaking, this operation is not a cycling in our time, because it is most often performed by electric planers or grinders.
Ski cycling is also known (including with plastic sliding surfaces). It is used both to smooth out minor damage to the sliding surface and to remove layers of sliding and protective ointments. In the latter case, soft cycles are used that do not damage the sliding surface, for example, of plastic.
