Research on the Machining Properties of Parashorea chinensis Wood for Engineering

In this paper, aiming to apply Parashorea chinensis to engineering, its machining properties (including planning, sanding, drilling, shaping, mortising and crosscutting) compared with Toona sinensis, were tested. Their properties were tested according to the criteria ASTM D1666-87 and the test on crosscutting was referred to the method established by New Zealand Forest Research Institute. The results shown: the machining properties of Parashorea chinensis and Toona sinensis in the planning, sanding, shaping and crosscutting show excellent; the mortising properties of Parashorea chinensis and Toona sinensis are separately fair and good; in the machining performance comprehensive evaluation system of full marks 50 points, the comprehensive marks of Parashorea chinensis is 45.6 points, better than Toona sinensi 43.7 points, which shows that it is a kind of excellent wooden-products material for engineering and can be used to product high-grade furniture and so on.
