Qual è la differenza tra una pialla a filo e una pialla a spessore?

Quando si utilizza la pialla a filo il pezzo di legno che viene lavorato viene fatto scorrere sopra l’albero pialla, piallando così la superficie inferiore. Nella pialla a spessore invece il pezzo di legno lavorato viene posizionato sul pianale regolabile in altezza e avanza sotto l’albero pialla, lavorando la superficie superiore dell’asse. Esiste poi anche la pialla a filo e spessore che permette di effettuare entrambe le lavorazioni.

Thicknessers planers and wood planers

Planers are woodworking machines that are used to make a rough surface flat and smooth, or to reduce the thickness of a board, giving it a predetermined thickness. Surface planers allow you to perform surface planing, that is the process that allows you to obtain a smooth surface on a piece of wood. Thicknessers, on the other hand, are used to give a wooden plank a certain thickness. The thicknessing planers are therefore a combined machine that allows you to perform both processes with a single tool.

During the flush planing operations, the piece of wood is slid over the planer shaft and the lower surface is planed. The thickness that is removed can be adjusted by acting on the height of the table. During thickness planing, on the other hand, the piece of wood rests on the height-adjustable platform of the instrument, and advances under the planer shaft. In this way the upper surface of the wooden plank is processed.

The available models of thicknessers planers, as well as those that only allow the planing of the thickness or edge, must be connected to a dust extraction system before each process. Furthermore, all machines are equipped with protection systems. In fact, there are protective casings that have the task of preventing the operator from coming into direct contact with the transmission parts of the machine when it is in action.

Important features that must be taken into consideration when choosing thicknessers planers are certainly the size and height of the tops. In fact, these are characteristics that affect the machining that can be carried out and the pieces that can be machined. Also for thickness planers the dimensions of the worktops are important characteristics to be evaluated.
