Logs are peeled into thin sheets, typically 0.6 to 6 millimeters thick, to create veneer. Professional jargon refers to this phase as "slicing." Before turning a tree trunk, often called a log, into veneer, there are a few stages that need to be completed.
Choosing the right wood to cut and turn into veneer is a meticulous procedure that calls for skill, knowledge, and experience. Evaluating the manufacturing and quality of wood panels is an important first step. To produce veneers of superior quality, every log is examined separately based on a number of criteria, including straightness, surface flaws, size (diameter and length), color, form, and so forth.
The logs are prepared for slicing as soon as they arrive at the slicer facility. A smooth and superior slicing procedure is ensured by first stripping the trees of their bark and then immersing them in hot water baths to soften the wood fibers.
Once the logs have been steamed, they can be sliced into thin wood layers. They have the option to be either peeled or sliced. For peeling, the log is aligned beside a stationary knife from one end to the other. It is supported in the middle by a mechanical mechanism and spins on its axis. Similar to a pencil sharpener, the veneer is always in constant contact with the knife and is consistently unrolled. Rotary, vertical, or horizontal slicing is possible. Rotary slicing stands out as the most impressive technique.
The tree trunk, divided into four parts, spins on its axis against a stationary blade. Every rotation results in a layer of veneer being created. Logs are securely held in place on a table that moves in either a vertical or horizontal direction using suction or claws. Every time the log passes over the machine's blade, a veneer sheet is created.
Different patterns will be visible on the veneers depending on how the log is cut before slicing and the method of slicing.
Simple cutting: creates a cathedral grain design. It is claimed that the veneer exhibits a leaf-like design.
Quarter slicing: results in a straight pattern. It is claimed that the veneer has a pattern of straight grains.
Rotary slicing: produces a random grain pattern.
Following the cutting process, the veneer sheets, which are still warm and wet, are dried one by one. It is crucial to stack the veneer sheets in the same order they were made both before and after drying. Using the sheets in the same sequence later on will help to form a cohesive wood design.
Rotary slicing is both the most cost-effective and most decorative method for creating high-quality real wood surfaces. One cubic meter of wood can yield up to 2000 m² of veneer. No other wood processing method can rival slicing in terms of efficiency and sustainability of natural resource utilization.
