parallel to the grain

The basic density, compression strength parallel to the grain, and tensile strength parallel to the grain and bending strength increase with the age, and reach their relative stableness values at the age of 3-5 years.

基本密度、顺纹抗压强度、顺纹抗拉强度和抗弯强度都随竹龄增加而增加，至3～5年较稳定。

The CNC processing technology of the wood testing part in tensile strength parallel to the grain

模板的加工橄榄球的加工木材顺纹抗拉强度试件的数控加工技术

First of all, through analyzing the size and process requirements of the prepared timber, it determines the composition and layout of the chipper which is NC energy-saving parallel to the grain, including automatic feeding and discharging mechanism and the main cutting bodies.

通过对加工木材的尺寸和工艺要求的分析，确定了数控节能顺纹削片机的组成和布局，这其中包括切削加工机构、自动进料机构和自动出料机构的设计。
