What rotary cutting machine is used in the production of birch veneer
The choice of rotary cutting machine directly affects the quality and yield of birch veneer production. At present, the mainstream equipment in the industry mainly consists of card and non card rotary cutting machines, and some high-end production lines use card and non card integrated rotary cutting machines to meet the processing needs of different specifications of birch wood.
The card rotary cutting machine is a traditional core equipment for birch veneer production, especially suitable for large-diameter logs. Taking the Finnish Raute R5 rotary cutting machine as an example, it adopts a dual spindle and fixed pressure gauge structure, combined with modern optimal rotary cutting geometry (OPG) technology, which can accurately adjust the tool clearance and pitch angle through the touch screen interface, ensuring that the uniformity error of the single board thickness is controlled within ± 0.05mm. This model has a wide range of wood segment diameters, with a minimum core diameter of only 55mm and a rotary cutting speed of up to 300 meters per minute, making it suitable for efficient processing of hard woods such as birch.
The cardless rotary cutting machine demonstrates advantages in the utilization of small-diameter birch wood. The domestically produced CNC cardless rotary cutting machine drives precision screw feed through servo motors, achieving stepless adjustment of thickness from 0.2mm to 3.8mm, and can adapt to different wood species without the need to replace gears. Its dual pressure roller anti bending technology and automatic cutting function for broken boards can effectively improve the yield of birch veneer.
The integrated rotary cutting machine with and without card represents the forefront of industry technology. The four meter model introduced by Mudanjiang Xusheng Wood Processing Factory from Japan can complete the continuous conversion of rotary cutting with and without card shafts on the same production line, especially suitable for the diverse raw material specifications in birch veneer production.
