In this paper, the machining properties of Toona sinensis, compared with Castanopsis hystrix, were tested. Their properties were conducted 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 show that four kinds of machining properties(planning, sanding, shaping and crosscutting) of Toona sinensis show excellent, and the drilling and mortising properties a bit poor, show good; but, the machining properties of Castanopsis hystrix in the planning, sanding, drilling, shaping and crosscutting all show excellent, the mortising properties, a bit poor, show good; in the machining performance comprehensive evaluation system for full marks 50 points, their comprehensive marks are separately 43.9 points and 44.4 points, so that both of them have excellent machining property.
