Avalia??o da madeira de Eucalyptus camaldulensis Dehnh e Eucalyptus urophylla S.T. Blake em ensaios de usinagem, visando à produ??o moveleira

摘要

The objective of this research was to conduct machining tests in woods of 6 and 8-year-old Eucalyptus urophylla and of a ten-year old Eucalyptus camaldulensis and to evaluate their possible use by the furniture industry. The wood samples were obtained from six trees of each clone, planted in a consortium with cattle and grain, owned by Votorantim Metals and Zinc. The plantation is located in the neighborhood of the city of Vazante, in the State of Minas Gerais. The following essays were conducted: cut by a table saw either parallel or perpendicular to the grain; shaping; planing; drilling; routing; mortising and drilling for dowels. All the samples yielded satisfactory results, mainly the eight year old Eucalyptus urophylla, during parallel-to-the-grain and mortising sawing. Woods from the clones tested seem very appropriate for furniture production. In fact, the samples did not show any difficulties during machining.
