The veneer particle board has a symmetrical structure, and the veneer, the fine shaving layer and the coarse shaving layer are respectively arranged from the surface to the inside. When the veneer particle board is milled by one milling cutter, the milling workload is large, and in order to avoid the phenomenon that the cutter is abraded too fast and the surface is not flat and broken due to overlarge cutting force, the veneer particle board is milled by adopting two milling cutters in a staggered mode, so that the milling surface quality is ensured, and the milling efficiency is also improved.

The design is that the milling depth is low, the rotating speed of the cutter shaft is accelerated, and the feed amount of each tooth is shortened, so that higher milling surface quality is obtained. Because the veneer facing wood shaving board structure is symmetrical structure, from the surface to inside be veneer, thin wood shaving, thick wood shaving respectively. Because the milling length is longer, the cutter is prevented from being worn too fast and the surface is not flat and broken due to overlarge cutting force, and therefore, two integral milling cutters are adopted to mill the veneer flakeboard in a staggered manner.
