旋切机基本原理
Basic Principle of Rotary Cutting Machine
旋切机用来将木段旋切成单板。旋切的一般方法是：左右卡轴夹紧木段两端并带动其旋转，安装在刀床上的旋刀刀刃平行于卡轴轴线并沿其垂直方向做进给运动，沿木段年轮方向旋切出等厚的单板。
The rotary cutting machine is used to cut wood segments into veneers. The general method of rotary cutting is that the left and right clamping axles clamp the two ends of the wood segment and drive it www.xiekou.net.cn www.wantou.net.cn www.buxiugangdai.net.cn www.zhenkongdiaoju.cn www.goucaoguanjia.cn www.kagu.org.cnto rotate. The blade of the rotary knife installed on the knife bed is parallel to the axis of the clamping axle and moves along its vertical direction. The veneer with equal thickness is rotated along the direction of the tree ring of the wood segment.
无论是恒转速旋切，还是恒线速旋切，为了获得一定厚度的单板，都应使卡轴每转一转，刀床的进给量保持不变，其进给量大小等于单板的名义厚度。改变这个进给量，就可获得不同厚度的单板。
Whether constant speed rotary cutting or constant linear speed rotary cutting, in order to obtain a certain thickness of veneer, the clamp shaft should be rotated once, the feed of the cutter bed should remain unchanged, and its feed is equal to the nominal thickness of veneer. By changing this feed rate, veneers of different thicknesses can be obtained.
