Description

Technical Field

[0001] The invention relates to the field of furniture, in particular to a method for cutting small-diameter solid wood. Background Art

[0002] With the implementation of the natural forest protection project, the timber production has been reduced year by year, resulting in less and less large-diameter timber available for use, and the proportion of small-diameter timber from artificial forests that enter thinning and main felling is increasing. However, due to the small diameter of small-diameter timber from artificial forests (8cm to 14cm in diameter), there is a lot of stress during the growth process. The wood blocks formed by cutting the outer layer of solid wood during the cutting process are very prone to surface cracking, internal cracking, deformation, shrinkage and other defects, which limits the utilization of small-diameter timber.

[0003] Therefore, a cutting method is proposed which can preliminarily eliminate stress before and after cutting. Summary of the invention
