TRABAJABILIDAD
Aserrado
Cutting resistance is reported to be generally high.
Corte de chapa rotativa
It is unsuitable for plywood because of its density.
Chapa tranchada
It is unsuitable for plywood because of its density.
Pérdida de filo_romado
Blunting effect on cutting edges is rated as moderate to high.
Maquinado general
The wood of green heart gives satisfactory results in all machining operations.
Cepillado
A reduced cutting angle of 20 degrees is recommended for planing because of interlocked grain and high density.
Clavado
The material is reported to require pre-boring.
Encolado
Gluing properties are reported to be variable. Special care needed in gluing.
Acabado
The timber is reported to give a lustrous finish.
Doblar al vapor
It is reported to have moderate steam bending properties but it is not recommended for that application.
