Mechanization

&;8226; Sawing process: high power is required but with no other difficulties.
&;8226; Drying process: slow, high risk of crack formation.
&;8226; Planing process: difficult due to hardness, although risk of repelling only appears on pieces of intertwined fibers.
&;8226; Gluing process: no difficulties.
&;8226; Nailing and screwing process: pre-drilling is required due to its hardness.
&;8226; Finish: no difficulties.
