Analysis of the Maximum Rotary Cutting Diameter Parameter of Single Board Spinning Machine
As the core equipment for the production of plywood, ecological board and other boards, the maximum rotary cutting diameter parameter of the veneer veneer machine directly affects the utilization rate and processing efficiency of wood. The mainstream models in the current market have formed differentiated diameter adaptation ranges based on their design positioning and technical characteristics.
Traditional models with card shafts are limited by the card head structure, and the maximum rotary cutting diameter is usually in the range of 400-800mm. For example, early single axle models were limited in torque transmission and could only handle wood segments with a diameter of less than 400mm, and the remaining wood core diameter was relatively large, resulting in resource waste. The hydraulic dual card shaft model expands the maximum diameter to 800mm through the coordinated work of the inner and outer card shafts, but the diameter of the wood core still reaches 70-120mm, which is suitable for the initial rotation of large-diameter logs.
The non card axis model breaks through the limitations of card axis structure with friction roller drive technology. Taking the XY-1400 CNC cardless rotary cutting machine as an example, its maximum rotary cutting diameter reaches 600mm, and the minimum processing diameter is compressed to 40mm through an elastic clamping mechanism, reducing the residual amount of wood core by more than 10%. The more advanced 8-foot hydraulic single card models (such as BQ1266/8E) can even increase the maximum diameter to 800mm, and with the centering upper wood system, achieve efficient utilization of large-diameter wood segments.
The direction of technological breakthroughs focuses on improving material strength and transmission accuracy. In 2024, the patented technology utilizes a T-shaped slider linkage structure and an annular gear rack transmission, enabling the equipment to maintain a repeat positioning accuracy of ± 0.05mm even when processing a diameter of 600mm. The application of infrared diameter detection system realizes real-time dynamic adjustment of cutting parameters, ensuring the uniformity of single board thickness.
