Wood planing is a surface leveling technique, a necessary processing step. It consists in removing a layer of material to remove large irregularities, roughnesses and other defects that appeared during sawing.
Planing is straight and profiled. In the first case, flat surfaces are processed, in the second – curved details. When large volumes of work are involved, high-precision machines are used in production that can process lumber of different sizes in a matter of minutes. Machines allow high precision, down to the millimeter. The surface of the products is very smooth and does not need to be sanded.
The sphere of application of planed lumber:
- Furniture manufacturing;
- Interior and exterior cladding;
- For flooring;
- For the manufacture of stairs;
- Building houses and other objects;
- Construction of fences.
Before planing, the wood must be prepared. Logs are sawn into boards, bars of different lengths and thicknesses, and the edges are trimmed. Depending on the purpose of the lumber for planing, several types of machines are used: planer, planer and combined. A four-sided planer is used to process the lumber on all sides at once. It is used to process surfaces and make shaped profiles.
High-precision planing is needed to produce smooth surfaces for joinery. For example, table tops, window sills, staircases.
